HelloPharmacist Scorecard of GABA 750 mg by NusaPure

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

NusaPure GABA 750 mg contains one active ingredient: GABA (gamma-aminobutyric acid), an amino acid your brain naturally makes. The capsule also holds cellulose, magnesium stearate, rice flour, and silica as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Gamma-aminobutyric Acid (gaba) product and its label doesn't state a use — see Gamma-aminobutyric Acid (gaba)'s own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for GABA isn't established yet in the data we hold. We have insufficient reliable evidence to rate it for anxiety, ADHD, athletic performance, cerebral palsy, or chronic bronchitis.

If you're considering this supplement for any of these reasons, talk with your doctor about what the current research shows and whether it makes sense for your situation.

The evidence, ingredient by ingredient Gamma-aminobutyric Acid (gaba)

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

GABA taken by mouth is generally well tolerated short-term, but long-term safety hasn't been well studied, so caution is warranted with longer use. The most common side effects reported are drowsiness, nausea, stomach upset, minor throat burning, and muscle weakness.

There isn't enough safety information to recommend this product during pregnancy; the data we hold doesn't address pregnancy safety. There also isn't enough information to know if it's safe while breastfeeding — talk with your doctor or pharmacist for personalized advice.

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?
  • 1 of the 1 matched ingredient can interact with medications — Gamma-aminobutyric Acid (gaba).
  • The most serious interaction on file is rated Moderate.
  • For scale: 419 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.

Check with your doctor or pharmacist before taking this if you're on blood pressure medications — GABA may lower your pressure further. Also double-check if you take sedating drugs or sleep aids, as GABA might increase drowsiness.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

GABA 750 mg might appeal to someone exploring options for relaxation, but the evidence for its effectiveness isn't solid yet. If you're on blood pressure medication or take sedating drugs, you'll want to clear this with your doctor or pharmacist first — GABA could add to their effects.

Long-term safety is an open question, so this isn't a take-forever supplement without discussion.

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.

GABA 750 mg by NusaPure: Common Questions

Does GABA 750 mg by NusaPure interact with any medications?
Yes. Based on its ingredients, GABA 750 mg has a known interaction with 419 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
GABA 750 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is GABA and what does it do?
GABA (gamma-aminobutyric acid) is an amino acid your brain naturally produces to help with relaxation. This supplement contains 750 mg of it, though the evidence for its effectiveness in pills is still unclear.
Can I take GABA if I'm pregnant or breastfeeding?
There isn't enough safety information about GABA in pregnancy to know either way — talk with your doctor or pharmacist about whether it's right for you. The data advises against use while breastfeeding.
What are the most common side effects?
The most common ones reported are drowsiness, nausea, stomach upset, minor throat burning, and muscle weakness. Most people tolerate it well in the short term, but long-term safety hasn't been thoroughly studied.
Will GABA help with my anxiety?
We have insufficient reliable evidence to rate GABA for anxiety, so we can't say whether it works for that. If you're looking to treat anxiety, your doctor can discuss options with better evidence behind them.
What's in the capsule besides GABA?
The capsule contains cellulose, magnesium stearate, rice flour, and silica — these are inactive ingredients (fillers and binders) that make up the capsule itself, not the active part.
How long can I safely take GABA?
GABA seems well tolerated for short-term use, but long-term safety hasn't been well studied. If you're planning to take it regularly, discuss duration with your doctor or pharmacist.
