HelloPharmacist Scorecard of Veggies by Amen
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
Amen Veggies is a vegetable supplement capsule containing 13 ingredients: spirulina, pea protein, green tea, alfalfa, barley grass, carrot, spinach, reishi mushroom, maitake mushroom, chaga mushroom, broccoli, and lion's mane mushroom powders, plus a "Raw Whole Veggies Blend" of component ingredients listed individually. The supplement also contains methylcellulose as an inactive ingredient (a binder).
The formula combines whole-food powders with adaptogenic mushrooms (reishi, maitake, chaga, lion's mane) and cruciferous vegetables (broccoli, spinach, carrot). Spirulina and barley grass are nutrient-dense algae and grasses, while pea protein provides plant-based protein.
Green tea brings polyphenols and caffeine into the mix.
Does it work?
Strong evidence
The evidence varies widely by ingredient. Barley grass is likely effective for high cholesterol and heart disease risk.
Green tea shows likely effectiveness for human papillomavirus (HPV) and possibly effective for high cholesterol. Spirulina is possibly effective for high blood pressure.
Carrot is possibly effective for vitamin A deficiency. For most other proposed uses — including diabetes, allergies, muscle soreness, cognitive function, and cancer — the evidence we hold is insufficient to rate these ingredients reliably.
The mushroom ingredients (reishi, maitake, chaga, lion's mane), pea protein, alfalfa, and spinach all lack established effectiveness evidence in our data for their commonly marketed uses.
How safe is it?
Well-documented data
Overall, most ingredients in this formula are generally well tolerated when used short-term. Spirulina, pea protein, green tea, alfalfa, barley grass, carrot, spinach, reishi, maitake, chaga, broccoli, and lion's mane are generally well tolerated, though common mild side effects across the group include bloating, gas, diarrhea, and nausea — particularly at higher doses.
A few more serious but rare concerns exist: green tea extract in high doses has been linked to liver injury; spirulina quality varies and some products carry contamination with toxins or heavy metals; barley contains gluten; carrot and pea can trigger allergies in sensitive individuals; and chaga contains high oxalate levels, with two reported cases of kidney failure from excessive consumption. Anaphylaxis has been reported rarely with spirulina, green tea (matcha), barley, carrot, and pea protein in allergic individuals.
Long-term safety for reishi, maitake, chaga, and lion's mane mushrooms is not well established. For pregnancy: green tea is possibly safe in moderate amounts but avoid high-dose extracts; barley and spinach are likely safe as foods; broccoli is likely safe; carrot is likely safe as food but avoid high-dose supplements; pea protein has insufficient data so discuss with your doctor; alfalfa, reishi, maitake, chaga, and lion's mane all have insufficient or inadequate data — talk with your doctor or pharmacist before using during pregnancy.
For breastfeeding: green tea is possibly safe in moderate amounts (caffeine passes to milk); spinach and barley are generally fine; carrot, pea, and broccoli have insufficient data; alfalfa, reishi, maitake, chaga, and lion's mane are not well studied — check with your doctor or pharmacist.
Meds to double-check
Major interaction found
Before you take Amen Veggies, double-check with your doctor or pharmacist if you're on any of these: blood thinners like warfarin (Major concern from alfalfa's vitamin K and moderate from spirulina, chaga, and lion's mane); beta-blockers like nadolol (Major from green tea); cholesterol drugs like atorvastatin (Major from green tea); seizure medications like phenytoin, valproate, ethosuximide, or felbamate (Moderate from green tea); stimulants like ephedrine (Major from green tea); blood pressure medications (Moderate from reishi and maitake); diabetes drugs (Moderate from spirulina, alfalfa, spinach, reishi, maitake, chaga, and lion's mane); immunosuppressants (Moderate from spirulina, alfalfa, chaga, and lion's mane); hormone therapy or birth control (Moderate from alfalfa); or drugs processed through CYP1A2 or CYP2A6 liver enzymes (Moderate from broccoli). Turkey tail mushroom could not be checked against our data.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
Amen Veggies is a whole-food vegetable and mushroom powder blend. It may appeal to people looking for concentrated nutrition or adaptogenic mushroom support, particularly those interested in barley's heart-health and cholesterol benefits or green tea's antioxidants.
However, if you take any prescription medication — especially blood thinners, beta-blockers, diabetes drugs, seizure medications, birth control, hormone therapy, or immunosuppressants — you need to review your specific drugs against the interaction list before starting. Talk with your doctor or pharmacist about whether this supplement fits safely into your personal medication routine.

Veggies by Amen Drug Interactions
HelloPharmacist Interaction Report
Amen Veggies contains several ingredients with documented interactions: spirulina, green tea, alfalfa, spinach, reishi mushroom, maitake mushroom, chaga mushroom, broccoli, and lion's mane mushroom.
The most serious interaction involves green tea with nadolol (a beta-blocker for heart conditions), ephedrine (a stimulant), and atorvastatin (a cholesterol drug) — all Major severity — where green tea can significantly reduce how well these medications work.
Read the full breakdown — every affected drug type, severity by severity
Beyond those three, green tea also has Moderate interactions with seizure medications (felbamate, valproate, ethosuximide, and phenytoin), where caffeine in the tea may theoretically reduce their anticonvulsant effects. It can also interfere with dipyridamole, used during stress testing.
Spirulina theoretically raises bleeding risk with anticoagulants or antiplatelets, and may lower blood sugar with diabetes drugs or interfere with immune-suppressing medications. Alfalfa carries a Major interaction with warfarin (a blood thinner) because it contains high vitamin K, which opposes warfarin's effect; it also has Moderate concerns with diabetes drugs, birth control, hormone therapy, and immune-suppressing drugs.
Spinach contains vitamin K and theoretically increases diabetes drug effects. Reishi, maitake, chaga, and lion's mane mushrooms all have Moderate interactions with blood pressure medications, blood thinners or platelet drugs, and diabetes medications.
Broccoli may reduce levels of drugs processed through specific liver pathways (CYP1A2 and CYP2A6 substrates).
We could not check turkey tail mushroom for interactions because we hold no data on it. Pea protein and carrot powder show no documented interactions.
Altogether, these interactions span 1,496 individual medications.

For each ingredient in Veggies with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Green Tea, Powder
Atorvastatin (Lipitor)
Green tea extract seems to reduce the levels and clinical effects of atorvastatin.
In healthy humans, taking green tea extract 300 mg or 600 mg along with atorvastatin reduces plasma levels of atorvastatin by approximately 24%. The elimination of atorvastatin is not affected. Atorvastatin is a substrate of organic anion-transporting polypeptides (OATPs). Research shows that two of the major catechins found in green tea, epicatechin gallate (ECG) and epigallocatechin gallate (EGCG), inhibit OATPs. Some OATPs are expressed in the small intestine and are responsible for the uptake of drugs and other compounds, which may have resulted in reduced plasma levels of atorvastatin. It is not clear if drinking green tea alters the absorption of atorvastatin.
Ephedrine
Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Green tea 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.
Nadolol (Corgard)
Green tea seems to reduce the levels and clinical effects of nadolol.
Preliminary clinical research shows that green tea consumption reduces plasma concentrations of nadolol. Compared to a control group, both peak levels and total drug exposure (AUC) of nadolol were reduced by approximately 85% in subjects who drank green tea daily for two weeks. Drinking green tea with nadolol also significantly reduced nadolol's systolic blood pressure lowering effect. Other clinical research shows that a single dose of green tea can affect plasma nadolol levels for at least one hour. Green tea catechins have been shown to inhibit organic anion transporting polypeptides (OATP), one of which, OATP1A2, is involved in the uptake of nadolol in the intestine The interaction is thought to be due primarily to the epigallocatechin gallate (EGCG) content of green tea.
5-Fluorouracil
Theoretically, high doses of green tea might increase the effects and side effects of 5-fluorouracil.
Animal research shows that taking green tea in amounts equivalent to about 6 cups daily in humans for 4 weeks prior to receiving a single injection of 5-fluorouracil increases the maximum plasma levels of 5-fluorouracil by about 2.5-fold and the area under the curve by 425%.
Adenosine (Adenocard)
Theoretically, green tea might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Green tea contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine doesn't seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines and 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.
Anticoagulant/Antiplatelet Drugs
Theoretically, green tea may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Conflicting reports exist regarding the effect of green tea on bleeding risk when used with anticoagulant or antiplatelet drugs; however, most evidence suggests that drinking green tea in moderate amounts is unlikely to cause a significant interaction. Green tea contains small amounts of vitamin K, approximately 7 mcg per cup. Some case reports have associated the antagonism of warfarin with the vitamin K content of green tea. However, these reports are rare, and very large doses of green tea (about 8-16 cups daily) appear to be needed to cause these effects. Furthermore, the catechins and caffeine in green tea are reported to have antiplatelet activity.
Beta-Adrenergic Agonists
Green tea contains caffeine. Theoretically, concomitant use of large amounts of caffeine might increase cardiac inotropic effects of beta-agonists.
Bortezomib (Velcade)
Theoretically, green tea might interfere with the effects of bortezomib.
In vitro research shows that green tea polyphenols, such as epigallocatechin gallate (EGCG), interact with bortezomib and block its proteasome inhibitory action. This prevents the induction of cell death in multiple myeloma or glioblastoma cancer cell lines. Advise patients taking bortezomib, not to take green tea.
Carbamazepine (Tegretol)
Theoretically, green tea might reduce the effects of carbamazepine and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when taken in doses above 400 mg/kg. Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine 2-fold in healthy individuals.
Celiprolol (Celicard)
Theoretically, green tea might reduce the levels and clinical effects of celiprolol.
In a small human study, taking green tea daily for 4 days appears to decrease blood and urine levels of celiprolol by at least 98%. This interaction is possibly due to the inhibition of organic anion transporting polypeptide (OATP). Green tea catechins have been shown to inhibit organic anion transporting polypeptides (OATP), one of which, OATP1A2, is found in the intestine The interaction is thought to be due primarily to the epigallocatechin gallate (EGCG) content of green tea.
Cimetidine (Tagamet)
Theoretically, concomitant use might increase the effects and adverse effects of caffeine in green tea.
Green tea contains caffeine. Cimetidine can reduce caffeine clearance by 31% to 42%.
Clozapine (Clozaril)
Theoretically, green tea might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Animal research suggests that, although green tea extract does not affect the elimination of clozapine, it delays the time to reach peak concentration and reduces the peak plasma levels. Also, concomitant administration of green tea and clozapine might theoretically cause acute exacerbation of psychotic symptoms due to the caffeine in green tea. 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.
Contraceptive Drugs
Theoretically, concomitant use might increase the effects and adverse effects of caffeine found in green tea.
Green tea contains caffeine. Oral contraceptives can decrease caffeine clearance by 40% to 65%.
Cytochrome P450 1A2 (Cyp1A2) Inhibitors
Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Caffeine is metabolized by cytochrome P450 1A2 (CYP1A2),. Theoretically, drugs that inhibit CYP1A2 may decrease the clearance rate of caffeine from green tea and increase caffeine levels.
Dipyridamole (Persantine)
Theoretically, green tea might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Green tea contains caffeine. Caffeine might inhibit dipyridamole-induced vasodilation. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.
Disulfiram (Antabuse)
Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
In human research, disulfiram decreases the clearance and increases the half-life of caffeine.
Diuretic Drugs
Theoretically, using green tea with diuretic drugs might increase the risk of hypokalemia.
Green tea contains caffeine. In excessive amounts, caffeine can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.
Estrogens
Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Estrogen inhibits caffeine metabolism.
Ethosuximide (Zarontin)
Theoretically, green tea might reduce the effects of ethosuximide and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that caffeine 92.4 mg/kg can decrease the anticonvulsant activity of ethosuximide. However, this effect has not been reported in humans.
Felbamate (Felbatol)
Theoretically, green tea might reduce the effects of felbamate and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that a high dose of caffeine 161.7 mg/kg can decreases the anticonvulsant activity of felbamate. However, this effect has not been reported in humans.
Fexofenadine (Allegra)
Green tea can decrease blood levels of fexofenadine.
Clinical research shows that green tea can significantly decrease blood levels and excretion of fexofenadine. Taking green tea extract with a dose of fexofenadine decreased bioavailability of fexofenadine by about 30%. In vitro, green tea inhibits the cellular accumulation of fexofenadine by inhibiting the organic anion transporting polypeptide (OATP) drug transporter. Research shows that two of the major catechins found in green tea, epicatechin gallate (ECG) and epigallocatechin gallate (EGCG), inhibit OATPs, specifically OATP1A2, OATP1B1, and OATP2B1. In addition, green tea has been shown to reduce the absorption of some drugs that are OATP substrates.
Flutamide (Eulexin)
Theoretically, green tea might increase the levels and adverse effects of flutamide.
Green tea contains caffeine. In vitro evidence suggests that caffeine can inhibit the metabolism of flutamide. Theoretically, concomitant use of caffeine and flutamide might increase serum concentrations of flutamide and increase the risk adverse effects.
Fluvoxamine (Luvox)
Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Fluvoxamine reduces caffeine metabolism.
Hepatotoxic Drugs
Theoretically, concomitant use might have additive adverse hepatotoxic effects.
Green tea extract supplements have been linked to several cases of hepatotoxicity and might have additive hepatotoxic effects with other drugs..
Imatinib (Gleevec)
Theoretically, green tea might reduce the levels and clinical effects of imatinib.
In animal research, a single dose of green tea extract reduces the area under the curve (AUC) of imatinib by up to approximately 64% and its main metabolite N-desmethyl imatinib by up to approximately 81%. This interaction has not been shown in humans. The mechanism of action is unclear but may involve multiple pathways.
Alfalfa, Powder
Warfarin (Coumadin)
Theoretically, alfalfa might reduce the anticoagulant activity of warfarin.
Alfalfa contains a large amount of vitamin K. This could theoretically interfere with the activity of warfarin.
Antidiabetes Drugs
Theoretically, alfalfa might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that alfalfa decreases blood sugar in diabetic mice. Also, in one case report, a diabetic patient experienced hypoglycemia after consuming alfalfa extract. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Contraceptive Drugs
Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.
Estrogens
Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.
Immunosuppressants
Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.
Photosensitizing Drugs
Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.
Reishi Mushroom, Powder
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.
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.
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.
Spirulina, Powder
Anticoagulant/Antiplatelet Drugs
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.
Antidiabetes Drugs
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.
Immunosuppressants
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Chaga Mushroom, Powder
Anticoagulant/Antiplatelet Drugs
Theoretically, chaga may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that chaga extract can inhibit platelet aggregation. This effect has not been reported in humans.
Antidiabetes Drugs
Theoretically, taking chaga with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that chaga might decrease blood glucose levels and increase insulin levels. This has not been reported in humans.
Immunosuppressants
Theoretically, chaga might interfere with immunosuppressive therapy.
In vitro research suggests that certain constituents of chaga stimulate immune function. This has not been reported in humans.
Lion's Mane Mushroom, Powder
Anticoagulant/Antiplatelet Drugs
Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation.
Antidiabetes Drugs
Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin.
Immunosuppressants
Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system.
Maitake Mushroom, Powder
Antidiabetes Drugs
Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes.
Antihypertensive Drugs
Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.
Warfarin (Coumadin)
There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects.
Broccoli, Powder
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.
Cytochrome P450 2A6 (Cyp2A6) Substrates
Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.
Spinach, Powder
Antidiabetes Drugs
There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
Warfarin (Coumadin)
Spinach contains vitamin K, which can interfere with the activity of warfarin.
In human research, although eating spinach with one meal does not result in coagulation test results outside the therapeutic range, daily consumption for one week necessitates dose adjustment of warfarin. Individuals using anticoagulants should consume a consistent daily amount of spinach to maintain the effect of anticoagulant therapy.
Barley Grass, Powder
Triclabendazole (Egaten)
Theoretically, barley might decrease the clinical effects of triclabendazole.
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly. This effect has not been shown in humans.
