HelloPharmacist Scorecard of CalmEZ Brain Tonic by NutriCology

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

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 3 active ingredients: Ramulus uncariae (hook) extract, Jujube seed extract, and Silk Tree bark extract, all delivered in a proprietary blend. The capsule also includes inactive ingredients — microcrystalline cellulose, hydroxypropyl methylcellulose, and L-leucine — that serve as binders and flow agents.

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, rest.
  • 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 for these ingredients is incomplete. For Jujube seed extract, the data we hold rates its effectiveness as insufficient for aging skin, anemia, anxiety, asthma, and athletic performance — meaning there isn't enough reliable research to say whether it works for those uses.

No effectiveness ratings are on file for Ramulus uncariae or Silk Tree extracts.

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 seed extract is widely eaten as food and is likely safe in that form, but concentrated supplements haven't been well studied. A small clinical trial reported two cases of headache, one case of dry mouth, and one case of increased bowel movements; a separate study found three cases of mild diarrhea in newborns.

Silk Tree extract has limited human safety data — the facts advise using it carefully and under professional guidance. There isn't enough reliable information to know whether Jujube is safe while breastfeeding, and Silk Tree should be avoided during breastfeeding.

Jujube itself is rated Likely Safe in pregnancy, but Silk Tree was traditionally avoided in pregnancy due to insufficient safety data.

Side effects, ingredient by ingredient Zizyphus Albizia Julibrissin

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 Brain Tonic, check any CNS depressants you use — sleeping pills, sedatives, and certain pain relievers — as Silk Tree and Jujube extracts may amplify their effects (Moderate severity). Also double-check if you take CYP1A2 substrates (some antidepressants and other drugs), because Jujube may lower their effectiveness (Moderate).

And if you're on diabetes medications, Jujube may increase your risk of low blood sugar (Moderate).

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.

This product may appeal to you if you're exploring herbal brain tonics, but it's not straightforward. Two of its three active ingredients interact significantly with common medications — especially sedatives and diabetes drugs.

Check your exact medications with the tool on this page before starting. And talk with your pharmacist or doctor if you're pregnant, breastfeeding, or taking any prescriptions.

Each ingredient & the kinds of drugs it affects

For each ingredient in CalmEZ Brain Tonic 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.

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.

Likelihood Possible Evidence D

Silk Tree (Albizia julibrissin) (bark) extract1 drug type · 248 drugs

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 NutriCology: Common Questions

Does CalmEZ Brain Tonic by NutriCology 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.
Is it safe to take this while pregnant or breastfeeding?
Jujube seed extract is rated Likely Safe in pregnancy, but Silk Tree extract was traditionally avoided during pregnancy because there isn't enough safety data. For breastfeeding, there isn't enough information to know whether Jujube is safe, and Silk Tree should be avoided. Talk with your doctor or pharmacist before using this product if you're pregnant or nursing.
What does Jujube seed extract do in this formula?
The product facts we have rate Jujube's effectiveness as insufficient for aging skin, anemia, anxiety, asthma, and athletic performance — meaning the research isn't clear yet. We don't have information on what it's meant to do in this specific blend.
Will this make me drowsy?
Jujube and Silk Tree extracts both have sedative properties and may add to the effects of sleep medications or other CNS depressants you're taking. If you're not on those types of drugs, we don't have data on drowsiness as a standalone side effect, though a small study did report headaches with Jujube seed extract.
Can this affect my blood sugar?
Jujube has shown hypoglycemic activity in animal research, meaning it may theoretically increase the risk of low blood sugar if you're on diabetes medications. However, a small human study found that Jujube fruit powder did not reduce fasting blood glucose levels. Check with your pharmacist or doctor before adding this if you take diabetes drugs.
What's in the capsule besides the active ingredients?
The capsule contains microcrystalline cellulose (a filler), hydroxypropyl methylcellulose (a binder), and L-leucine (an amino acid used as a flow agent). These are inactive ingredients.
