HelloPharmacist Scorecard of CalmEZ Brain Tonic by Allergy Research Group

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

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 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1.80 Gram(s)) without saying how much of each component you get.

CalmEZ Brain Tonic contains three active ingredients. Jujube (Ziziphus mauritianae) seed extract and Silk Tree (Albizia julibrissin) bark extract are traditional plant extracts included for their calming properties.

Ramulus uncariae (hook) extract — a botanical also known as cat's claw — rounds out the formula. These are combined with inactive ingredients (capsule material, microcrystalline cellulose, and L-leucine) that help hold the supplement together.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: calming and sleep support.
  • We looked for evidence on: Anxiety, Insomnia, stress relief, relaxation.
  • The closest evidence on file: Zizyphus is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Zizyphus is rated "Insufficient Reliable Evidence To Rate" for Insomnia.

The evidence on jujube for the conditions it's traditionally used for — aging skin, anemia, anxiety, asthma, and athletic performance — is rated insufficient. We don't have enough reliable human data to say whether it works.

Albizia (Silk Tree) has no established effectiveness ratings in our data. Ramulus uncariae was not checked.

If you're considering this product for a specific health goal, talk with your pharmacist about what the current evidence actually shows.

The evidence, ingredient by ingredient Zizyphus Albizia Julibrissin

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 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Jujube fruit as a food is widely eaten and considered safe, but concentrated supplements haven't been well studied. A small clinical trial noted two cases of headache with jujube seed extract, plus occasional mild diarrhea, dry mouth, and changes in bowel movements in a handful of participants.

Silk Tree (Albizia) has limited human safety data and should only be used under professional guidance. For pregnancy, jujube is rated likely safe, but Silk Tree should be avoided — there isn't enough safety information.

For breastfeeding, jujube data is insufficient, so talk with your doctor; Silk Tree should be avoided due to lack of reliable safety data.

Meds to double-check

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?
  • 2 of the 2 matched ingredients can interact with medications — Zizyphus, Albizia Julibrissin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 469 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 CalmEZ, double-check if you're on any CNS depressants (Moderate severity) — sedatives, sleeping pills, anti-anxiety medications, or narcotic pain relievers — because jujube and Silk Tree may add to drowsiness or impair alertness. Also flag any diabetes medications (Moderate) that lower blood sugar, since jujube theoretically raises the risk of low blood sugar, and any drugs your liver metabolizes as CYP1A2 substrates (Moderate), where jujube may reduce their effectiveness.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

CalmEZ Brain Tonic may appeal to you if you're interested in traditional herbal support for calm and focus — but you'll want to check your medications first, especially sedatives, blood sugar drugs, and anything your liver processes as a CYP1A2 substrate. If you're pregnant or breastfeeding, discuss this with your pharmacist before starting.

Jujube (Ziziphus mauritianae) (seed) extract3 drug types · 469 drugs

Antidiabetes Drugs

Theoretically, zizyphus might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that zizyphus has hypoglycemic activity. However, a small clinical study shows that zizyphus fruit powder does not reduce fasting blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, zizyphus might cause additive sedative effects when taken with CNS depressants.
Some animal research has found that various parts of zizyphus have sedative effects. However, other animal research shows that zizyphus plant extract does not alter sleep parameters when used in combination with pentobarbital.

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

Theoretically, zizyphus might decrease the levels and clinical effects of drugs metabolized by CYP1A2.
Animal research shows that zizyphus induces CYP1A2 enzymes. However, this effect has not been reported in humans.

Cns Depressants

Animal research suggests that certain constituents from Albizia julibrissin flowers can potentiate pentobarbital-induced sleeping time in mice. Theoretically, Albizia julibrissin might enhance the therapeutic and adverse effects of CNS depressants.
Some CNS depressants include pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), clonazepam (Klonopin), lorazepam (Ativan), zolpidem (Ambien), and others.

CalmEZ Brain Tonic by Allergy Research Group: Common Questions

Does CalmEZ Brain Tonic by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, CalmEZ Brain Tonic has a known interaction with 469 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CalmEZ Brain Tonic contains 3 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 while I'm pregnant?
Jujube is rated likely safe in pregnancy, but Silk Tree (Albizia) should be avoided because there isn't enough safety data — it's traditionally been avoided during pregnancy. Talk with your doctor or pharmacist about your specific situation before starting.
Is it safe to breastfeed while taking this?
The data on jujube while breastfeeding is insufficient — we don't know either way — so ask your doctor or pharmacist. Silk Tree should be avoided because there's no reliable safety information.
What side effects did people experience in trials?
In a small study, jujube seed extract was linked to two cases of headache. Jujube fruit extract was associated with a few cases of mild diarrhea in infants, and the seed extract was linked to dry mouth and increased bowel movements in a couple of participants. Adverse effects were rare.
Does jujube actually lower blood sugar?
Animal research suggests it might, which is why we flag it as a theoretical risk with diabetes drugs. However, one small human study found that jujube fruit powder didn't actually reduce fasting blood sugar in people with type 2 diabetes, so the real-world effect in humans isn't clear.
What is Ramulus uncariae?
It's also known as cat's claw, a plant extract traditionally used in herbal supplements. We don't have interaction data for it, so we can't say how it might interact with your medications.
