HelloPharmacist Scorecard of Meditate by Codeage

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 4 of its 13 active ingredients.
  • “CodeAge Deep Blue Mind Enhancing Blend” is a proprietary blend — the label gives one combined amount (500 mg) without saying how much of each component you get.
  • “organic, wild-crafted Blueberry blend” is a proprietary blend — the label gives one combined amount (100 mg) without saying how much of each component you get.

Meditate contains 13 active ingredients across botanical extracts and compounds. The main players are GABA (gamma-aminobutyric acid, a relaxation neurotransmitter), NeuroFactor (a coffee fruit extract with caffeine), two cordyceps species, reishi and lion's mane mushroom extracts, rhodiola root, ashwagandha, and three types of blueberry.

There's also a proprietary "CodeAge Deep Blue Mind Enhancing Blend," dihydrohonokiol-B, and one inactive ingredient — vegetable cellulose capsule. These ingredients are chosen for brain health and calm, drawing on botanicals used in traditional medicine alongside compounds like GABA that support relaxation.

The mushroom extracts and blueberries bring polysaccharides and antioxidants; ashwagandha and rhodiola are adaptogens (plants traditionally used for stress); and the small amount of caffeine from coffee fruit may support alertness.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Stress and anxiety support with mental clarity.
  • We looked for evidence on: Anxiety, Age-related cognitive decline, Cognitive function, Mindfulness, Mental balance, Daily stress relief.
  • The strongest evidence on file: Ashwagandha is rated "Possibly Effective" for Anxiety (Natural Medicines).
  • Also on file: Ashwagandha is rated "Possibly Effective" for Generalized anxiety disorder (GAD), Stress.
  • Also on file: Bilberry is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline.

The evidence picture is mixed and largely incomplete. Ashwagandha shows Possibly Effective for anxiety, stress, and insomnia — making it the strongest candidate in this blend for calming effects.

NeuroFactor (coffee) is Likely Effective for mental alertness and Possibly Effective for heart health, Parkinson disease, and blood sugar control, though its benefit depends on caffeine dose and sensitivity. Cordyceps are rated Possibly Ineffective for athletic performance.

Reishi, lion's mane, blueberry ingredients, GABA, rhodiola, and the proprietary blend all have Insufficient Reliable Evidence To Rate for their claimed effects — meaning research hasn't yet shown them to be clearly effective or ineffective for anxiety, cognition, or the other conditions listed. In short: ashwagandha and caffeine have some backing, but most of this product's ingredients lack solid clinical proof of benefit for brain health or relaxation.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 9 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

GABA is often well tolerated short-term but long-term safety is unclear; avoid it unless your doctor advises otherwise. The most common side effects are drowsiness, nausea, gastric upset, throat burning, and muscle weakness.

Ashwagandha is generally well tolerated short-term in healthy adults, though quality varies and it's traditionally thought to risk miscarriage — avoid in pregnancy and do not breastfeed while taking it. Rare case reports link ashwagandha to liver problems (hepatitis, liver failure) and one case of intracranial bleeding; stop and seek medical attention if you notice jaundice, abdominal pain, or severe headache.

Cordyceps and reishi are generally well tolerated short-term with limited evidence, but avoid both in pregnancy and while breastfeeding due to insufficient safety data. The most common cordyceps side effects are abdominal discomfort, constipation, and diarrhea; one rare case of liver inflammation (cholestatic hepatitis) was reported.

Reishi may cause dizziness, dry mouth, nausea, itching, rash, or stomach upset. Lion's mane, rhodiola, and blueberries are generally well tolerated, though blueberry supplements (not whole fruit) may cause constipation, diarrhea, nausea, or vomiting, and one clinical trial saw 26% of participants drop out in week one due to GI complaints.

Caffeine is well tolerated in moderate amounts but can cause agitation, anxiety, insomnia, headache, and premature heartbeat, especially at high intakes or in children and older adults; withdrawal may cause headache and depressed mood.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Meditate is marketed for relaxation and mind support, with ashwagandha and GABA as its calming leads and caffeine from coffee for alertness. Most of the botanical ingredients lack strong evidence of benefit, and the product carries real risks — especially if you take blood-pressure meds, blood thinners, diabetes drugs, seizure or mood medications, or immunosuppressants.

Pregnancy and breastfeeding are not advised. Before starting, check your medications with the interaction tool on this page, and talk to your pharmacist or doctor if you're on any regular prescriptions.

Ashwagandha root & leaf extract10 drug types · 1,372 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Likelihood Possible Evidence C

organic Rhodiola rosea root extract10 drug types · 1,271 drugs

Antidiabetes Drugs

Theoretically, taking rhodiola with antidiabetes drugs might increase the risk of hypoglycemia.
In vitro and animal research shows that rhodiola extract can decrease blood glucose due to alpha-glucosidase activity.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
In vitro and animal research shows that rhodiola extract inhibits angiotensin-converting enzyme (ACE) and might lower blood pressure.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that rhodiola inhibits CYP2C9. This effect is highly variable and appears to be dependent on the rhodiola product studied. Also, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, rhodiola use might interfere with immunosuppressive therapy.
In vitro and animal research show that rhodiola has immunostimulatory effects.

Likelihood Possible Evidence D
Losartan (Cozaar)

Rhodiola might increase the levels and adverse effects of losartan.
A clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, rhodiola might increase levels of P-glycoprotein substrates.
In vitro research shows that rhodiola inhibits P-glycoprotein. Theoretically, using rhodiola with P-glycoprotein substrates might increase drug levels and potentially increase the risk of adverse effects.

Likelihood Possible Evidence D
Antidepressant Drugs

Theoretically, rhodiola might increase the risk of adverse effects when taken with antidepressants.
A review of adverse event reports in Poland identified cases of tachyarrhythmias, myalgia, arthralgia, gum pain, restless leg syndrome, swallowing disorders, and changes in consciousness when rhodiola was taken in combination with paroxetine, escitalopram, fluoxetine, sertraline, trazodone, and/or duloxetine.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that rhodiola inhibits CYP1A2. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of caffeine, a CYP1A2 substrate.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that rhodiola inhibits CYP3A4. This effect is highly variable and appears to be dependent on the rhodiola product studied.

Likelihood Possible Evidence B

NeuroFactor33 drug types · 591 drugs

Ephedrine

Theoretically, concomitant use might increase the risk of stimulant adverse effects.
Coffee contains caffeine. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death. Tell patients to avoid taking caffeine with ephedrine and other stimulants.

Likelihood Probable Evidence D
Adenosine (Adenocard)

Theoretically, coffee might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Coffee contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines such as caffeine, as well as methylxanthine-containing products, be stopped 24 hours prior to pharmacological stress tests. However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.

Likelihood Possible Evidence B
Alendronate (Fosamax)

Coffee reduces alendronate bioavailability.
Separate coffee ingestion and alendronate administration by two hours. Coffee reduces alendronate bioavailability by 60%.

Likelihood Probable Evidence B
Anticoagulant/Antiplatelet Drugs

Theoretically, coffee may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Coffee contains caffeine. Caffeine is reported to have antiplatelet activity. Theoretically, the caffeine in coffee might increase the risk of bleeding when used concomitantly with these agents. However, this interaction has not been reported in humans. There is some evidence that caffeinated coffee might increase the fibrinolytic activity in blood.

Likelihood Unlikely Evidence D
Beta-Adrenergic Agonists

Theoretically, concomitant use of large amounts of coffee might increase cardiac inotropic effects of beta-agonists.
Coffee contains caffeine. Caffeine can increase cardiac inotropic effects of beta-agonists.

Likelihood Probable Evidence D
Cimetidine (Tagamet)

Theoretically, cimetidine might increase the effects and adverse effects of caffeine in coffee.
Coffee contains caffeine. Cimetidine can reduce caffeine clearance by 31% to 42%.

Likelihood Likely Evidence B
Clozapine (Clozaril)

Theoretically, coffee might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Coffee contains caffeine. Caffeine can increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg daily inhibit clozapine metabolism. Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Researchers speculate that caffeine might inhibit CYP1A2. However, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients be more sensitive to the interaction between clozapine and caffeine.

Likelihood Possible Evidence B
Contraceptive Drugs

Theoretically, concomitant use might increase the effects and adverse effects of caffeine found in coffee.
Coffee contains caffeine. Oral contraceptive drugs can decrease caffeine clearance by 40% to 65%.

Likelihood Probable Evidence B
Dipyridamole (Persantine)

Theoretically, coffee might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Coffee contains caffeine. Caffeine is a methylxyanthine that may inhibit dipyridamole-induced vasodilation. It is recommended that methylxanthines such as caffeine, as well as methylxanthine-containing products such as coffee, be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.

Likelihood Probable Evidence B
Disulfiram (Antabuse)

Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
Coffee contains caffeine. In human research, disulfiram decreases the clearance and increases the half-life of caffeine.

Likelihood Probable Evidence B
Diuretic Drugs

Theoretically, concomitant use might increase the risk of hypokalemia.
Coffee contains caffeine. Caffeine, especially in excessive amounts, can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.

Likelihood Possible Evidence D
Estrogens

Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Coffee contains caffeine. Estrogen inhibits caffeine metabolism.

Likelihood Probable Evidence B
Fluvoxamine (Luvox)

Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Coffee contains caffeine. Fluvoxamine reduces caffeine metabolism.

Likelihood Probable Evidence B
Lamotrigine (Lamictal)

Coffee consumption can decrease the levels and clinical effects of lamotrigine.
A pharmacokinetic study in patients taking lamotrigine shows that consumption of coffee, both caffeinated and decaffeinated, can decrease the area under the concentration-time curve (AUC) and the peak plasma level (Cmax) of lamotrigine. Each additional cup of coffee reduced the AUC and Cmax by 4% and 3%, respectively. It is unclear whether this interaction is due to induction of lamotrigine metabolism or inhibition of lamotrigine absorption.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Coffee can reduce the absorption of levothyroxine.
In some patients, coffee can reduce levothyroxine absorption, possibly through the formation of non-absorbable complexes. A pharmacokinetic study in these patients found that 25-30 mL of espresso coffee consumed with levothyroxine tablets delayed the time to peak plasma levels by 38-43 minutes, reduced the peak plasma level (Cmax) by 19% to 36%, and reduced the area under the curve (AUC) by 27% to 36%. Coffee consumed one hour after levothyroxine did not affect absorption. It is not known whether this interaction occurs with other types of coffee. Tell patients to avoid drinking coffee at the same time that they take their levothyroxine, and for up to an hour afterwards.

Likelihood Possible Evidence B
Lithium

Theoretically, abrupt coffee withdrawal might increase the levels and adverse effects of lithium.
Coffee contains caffeine. Abrupt caffeine withdrawal can increase serum lithium levels. Two cases of lithium tremor that worsened with abrupt coffee withdrawal have been reported. There is also one case of a 2.8-fold increase in blood lithium levels after a patient taking lithium reduced his coffee consumption from 13-20 cups daily to 10 cups daily.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Coffee contains caffeine. Caffeine has been shown to inhibit monoamine oxidase (MAO) A and B in laboratory studies. Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis. In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension. Hypertension was resolved after the patient switched to drinking decaffeinated coffee.

Likelihood Possible Evidence D
Nicotine

Theoretically, concomitant use might increase the risk of hypertension.
Coffee contains caffeine. Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly.

Likelihood Probable Evidence B
Pentobarbital (Nembutal)

Theoretically, coffee might reduce the effects of pentobarbital.
Coffee contains caffeine. Theoretically, caffeine might negate the hypnotic effects of pentobarbital.

Likelihood Possible Evidence B
Phenylpropanolamine

Theoretically, phenylpropanolamine might increase the risk of hypertension, as well as the levels and adverse effects of caffeine.
Coffee contains caffeine. Concomitant use of phenylpropanolamine and caffeine might cause an additive increase in blood pressure. Phenylpropanolamine also seems to increase caffeine serum levels.

Likelihood Probable Evidence B
Pioglitazone (Actos)

Theoretically, coffee might increase the levels and clinical effects of pioglitazone.
Coffee contains caffeine. Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone. However, the exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Coffee contains caffeine. Concomitant use of caffeine and quinolones can decrease caffeine clearance and increase effects and risk of adverse effects.

Likelihood Probable Evidence B
Riluzole (Rilutek)

Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Coffee contains caffeine. Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce metabolism of one or both agents.

Likelihood Possible Evidence D
Stimulant Drugs

Theoretically, concomitant use might increase stimulant adverse effects.
Coffee contains caffeine. Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects.

Likelihood Probable Evidence C
Theophylline

Theoretically, coffee might increase the levels and adverse effects of theophylline.
Coffee contains caffeine, which can increase theophylline levels.

Likelihood Probable Evidence B

Gamma-Aminobutyric Acid2 drug types · 419 drugs

Antihypertensive Drugs

Theoretically, taking GABA with antihypertensive drugs might increase the risk of hypotension.
Some clinical research shows that GABA can decrease blood pressure in patients with hypertension.

Likelihood Possible Evidence B
Cns Depressants

Theoretically, GABA might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Endogenous GABA has well-established relaxant effects and GABA(A) receptors have an established physiological role in sleep. However, the effects of GABA supplements are unclear, as it is unknown whether exogenous GABA crosses the blood-brain barrier. Although there have been limited reports of drowsiness or tiredness with GABA supplements, these effects have not been widely reported in clinical studies. Additionally, intravenous GABA 0.1-1 mg/kg has been shown to induce anxiety in a dose-dependent manner.

Likelihood Unlikely Evidence D

organic Reishi Mushroom fruiting bodies extract3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.

Likelihood Possible Evidence D

Alpine Blueberry4 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro, animal, and clinical research suggest that anthocyanidin extracts from bilberry can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity. Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Erlotinib (Tarceva)

Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib. This interaction has not been reported in humans.

Likelihood Possible Evidence D

organic Cordyceps militaris fruiting bodies extract3 drug types · 249 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.

Likelihood Possible Evidence B
Testosterone

Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D

Alaska Blueberry3 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.

Likelihood Unlikely Evidence D
Buspirone (Buspar)

Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.

Likelihood Unlikely Evidence B
Flurbiprofen (Ansaid, Others)

Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.

Meditate by Codeage: Common Questions

Does Meditate by Codeage interact with any medications?
Yes. Based on its ingredients, Meditate has a known interaction with 1,575 medications, including 8 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Meditate contains 13 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Meditate while I'm pregnant?
No, you shouldn't. Ashwagandha is traditionally thought to risk miscarriage, and cordyceps, reishi, and rhodiola all lack enough safety data in pregnancy. GABA's pregnancy safety isn't clear either. Talk with your doctor before taking any supplement while pregnant.
Is it safe to breastfeed while taking this?
The safety data advises against it. Ashwagandha, cordyceps, reishi, and rhodiola all have not been well studied in breastfeeding. Caffeine passes into breast milk and can make babies fussy or sleepless. If you're breastfeeding, ask your pharmacist or doctor first.
What's the caffeine content, and will it keep me awake?
The product facts don't list the exact caffeine dose, but NeuroFactor is a coffee fruit extract, so it contains caffeine. If you're sensitive to caffeine or take it late in the day, it could interfere with sleep — especially since GABA may add drowsiness and the two effects could clash in unpredictable ways.
Does ashwagandha in this product really help with anxiety?
Ashwagandha is Possibly Effective for anxiety and stress in the clinical evidence we hold. That doesn't mean it will work for you, but it has the strongest backing of any ingredient here. Results vary, and it takes time — it's not a quick fix like a prescription anti-anxiety medication.
Are there any fillers or ingredients I should watch for?
The product has one inactive ingredient — vegetable cellulose capsule, which is the capsule itself. No other fillers are listed.
I take a blood-pressure medication. Can I use this?
Not safely without checking first. Several ingredients in Meditate — GABA, reishi, rhodiola, and ashwagandha — can theoretically lower blood pressure. Combined with your medication, you could end up with dangerously low blood pressure. Check this product against your exact drug using our medication tool, or ask your pharmacist.
