HelloPharmacist Scorecard of Sleep Synergy Drink Mix Chamomile by CBDistillery

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 1 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (58 mg) without saying how much of each component you get.
  • “Broad Spectrum Hemp Aerial Parts Extract” is listed as a grouped ingredient — the label gives one combined amount (30 mg) without saying how much of each component you get.

This drink mix contains four active ingredients. L-Theanine is an amino acid that supports relaxation and focus.

Valerian root extract is a plant remedy traditionally used for sleep. Chamomile extract comes from the chamomile flower and is commonly used to promote calm.

Cannabidiol (CBD) is derived from hemp, though we lack interaction data for this ingredient. The product also contains inactive ingredients — tapioca maltodextrin, natural chamomile flavor, other natural flavor, sugar, and stevia extract — which serve as sweeteners and carriers for the active compounds.

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: Sleep support and relaxation.
  • We looked for evidence on: Anxiety, Generalized anxiety disorder (GAD), Insomnia, Stress, Sleep quality, Relaxation — and 1 related terms.
  • The strongest evidence on file: Valerian is rated "Possibly Effective" for Insomnia (Natural Medicines).
  • Also on file: Valerian is rated "Insufficient Reliable Evidence To Rate" for Pre-procedural anxiety, Stress.
  • Also on file: German Chamomile is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Generalized anxiety disorder (GAD), Insomnia.

Valerian root extract is possibly effective for insomnia, making it a reasonable choice if that's your main goal. For L-Theanine and Chamomile extract, the evidence we hold does not establish effectiveness for sleep or anxiety — the ratings show insufficient reliable evidence.

The evidence base for these ingredients on sleep specifically is not established in our data, so you're relying partly on traditional use rather than proven benefit.

The evidence, ingredient by ingredient Theanine Valerian German Chamomile Hemp

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-Theanine is generally well tolerated in healthy adults for short-term use, though long-term safety isn't well studied. Reported side effects include headaches, drowsiness, and vivid dreams.

Valerian root extract is also generally well tolerated short-term but can cause dizziness, drowsiness, mental slowness, headache, and vivid dreams — and if you stop it abruptly after prolonged use, withdrawal symptoms like anxiety and insomnia can occur, so taper slowly. Chamomile extract is generally well tolerated but can cause allergic reactions in people sensitive to ragweed and related plants; severe reactions including anaphylaxis have been rarely reported.

Both L-Theanine and Valerian lack sufficient safety data in pregnancy and breastfeeding — the data advises against use during both periods. Chamomile also lacks enough reliable safety data in pregnancy and is best avoided unless your doctor approves; limited data exist for breastfeeding, so check with your pharmacist.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Valerian, German Chamomile, Theanine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 1,139 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check with your pharmacist if you take any of the following: blood pressure medications (antihypertensives) — Theanine may lower your pressure further; CNS depressants like sedatives, sleep aids, anxiety medications, or opioids — all three ingredients may increase drowsiness; oral contraceptives or estrogen hormone therapy — Chamomile may reduce their effectiveness; blood thinners like warfarin — Chamomile may increase bleeding risk; drugs metabolized by CYP2D6, CYP2C9, or CYP3A4 liver enzymes — Chamomile may raise their levels; alprazolam (Xanax) or other benzodiazepines; or alcohol. We could not check Cannabidiol, so its medication interactions remain unknown.

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

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

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

Valerian root extract6 drug types · 902 drugs

Alcohol (Ethanol)

Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba. However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone.

Likelihood Possible Evidence B
Alprazolam (Xanax)

Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Valerian has sedative effects. Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4). Despite being statistically significant, this increase is not likely to be clinically significant.

Likelihood Possible Evidence B
Cns Depressants

Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.

Likelihood Possible Evidence D
Glucuronidated Drugs

Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate.

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

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme. In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4. However, this mild inhibition is unlikely to be clinically relevant.

L-Theanine3 drug types · 565 drugs

Antihypertensive Drugs

Theanine might lower blood pressure, potentiating the effects of antihypertensive drugs.
Animal research shows that theanine can lower blood pressure in spontaneously hypertensive animals. Theoretically, concomitant use of theanine and antihypertensive drugs might potentiate the antihypertensive activity.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, theanine might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Theoretically, theanine may compete with glutamate and/or increase plasma gamma-aminobutyric acid (GABA) levels, which could cause CNS depression. In one clinical study, some subjects taking oral theanine reported drowsiness.

Likelihood Unlikely Evidence D
Serotonergic Drugs

Clinical studies regarding the effects of L-theanine on serotonin levels are conflicting. Some studies suggest it can increase serotonin levels in the brain while others report that it may decrease them. Nevertheless, there have been no reports of l-theanine being a causative agent in serotonergic-related side effects or serotonin syndrome.

Sleep Synergy Drink Mix Chamomile by CBDistillery: Common Questions

Does Sleep Synergy Drink Mix Chamomile by CBDistillery interact with any medications?
Yes. Based on its ingredients, Sleep Synergy Drink Mix Chamomile has a known interaction with 1,190 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sleep Synergy Drink Mix Chamomile contains 4 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 this if I'm pregnant or breastfeeding?
No. L-Theanine and Valerian both lack enough safety data, and the facts advise against both during pregnancy and breastfeeding. Chamomile also lacks reliable safety data in pregnancy and is best avoided unless your doctor approves; limited data exist for breastfeeding. Talk to your doctor or pharmacist about what's safe for you.
What side effects might I experience?
The most common are drowsiness, dizziness, headaches, and vivid dreams. L-Theanine may also cause increased dream activity. Valerian can cause mental slowness and gastrointestinal upset. Chamomile may cause allergic reactions, especially if you're sensitive to ragweed. If you take Valerian long-term and stop suddenly, you might experience withdrawal symptoms like anxiety and insomnia — taper slowly instead.
Does this actually work for sleep?
Valerian root extract is possibly effective for insomnia based on our data. For L-Theanine and Chamomile, we don't have enough reliable evidence to say whether they work for sleep — so you're relying on traditional use rather than proven benefit.
Is it safe to drink alcohol with this?
No. Valerian has additive sedative effects with alcohol, and mixing them could cause excessive drowsiness and impaired judgment. Avoid alcohol while using this product.
What if I'm allergic to ragweed?
Chamomile extract can trigger allergic reactions in people sensitive to ragweed and related plants — sometimes severe. If you have a ragweed allergy, check with your pharmacist before using this product.
Can I take this long-term?
The safety data for long-term use of L-Theanine and Valerian is not well studied, so we don't know if they're safe over months or years. If you plan to use this regularly, talk to your pharmacist about what's appropriate for you.
