HelloPharmacist Scorecard of GABA 750 mg by SuperiorLabs

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 11, 2026

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.

This product contains a single active ingredient: 750 mg of gamma-aminobutyric acid, commonly known as GABA. GABA is a neurotransmitter — a chemical messenger in your brain — that helps calm nerve activity and promote relaxation.

The capsule also contains cellulose and rice as inactive ingredients.

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 — see Gamma-aminobutyric Acid (gaba)'s own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support healthy cortisol levels and relaxation.
  • We looked for evidence on: Anxiety, Depression, Insomnia, Psychological well-being, Hypertension, stress — and 2 related terms.
  • The closest evidence on file: Gamma-aminobutyric Acid (gaba) is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Gamma-aminobutyric Acid (gaba) is rated "Insufficient Reliable Evidence To Rate" for Depression, Hypertension, Insomnia, Post-traumatic stress disorder (PTSD), and more.

The evidence for what GABA supplements actually do isn't established yet in the data we hold. It's been studied for anxiety, ADHD, chronic bronchitis, athletic performance, and cerebral palsy, but the research to date is insufficient to say whether it works for any of these purposes.

Your doctor or pharmacist can tell you more about what's emerging in the literature, but based on current reliable evidence, we can't rate its effectiveness.

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 is generally well tolerated in the short term, but long-term safety hasn't been well studied, so caution is warranted if you're thinking of taking it long-term. The most common side effects reported with oral GABA are drowsiness, stomach upset, minor throat burning, muscle weakness, and nausea.

One case reported a temporary loss of menstrual periods in a patient taking GABA with another supplement. There isn't enough safety data for pregnancy or breastfeeding — your doctor or pharmacist can discuss whether the unknown risks are acceptable for your situation.

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.

Before you take this product, check any blood pressure medications (Moderate risk of lowered blood pressure) and any CNS depressants like sedatives or sleep aids (Minor additive relaxation risk) with the search tool on this page.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

GABA might be worth considering if you're interested in its relaxing properties, but the evidence for what it actually does isn't solid yet. If you take blood pressure medication or any nervous system depressants, check with your pharmacist first.

Long-term safety is unclear, so talk to us before making it part of your routine.

Gamma-Aminobutyric Acid2 drug types · 419 drugs

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.

Does GABA 750 mg by SuperiorLabs 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 is it supposed to do?
GABA is gamma-aminobutyric acid, a chemical messenger in your brain that helps calm nerve activity. Supplements are marketed for relaxation and anxiety, but the reliable evidence to back up those claims isn't solid yet.
Can I take GABA if I'm on blood pressure medication?
That's a conversation you need to have with your pharmacist or doctor before you start. GABA may lower blood pressure further, which could be risky if you're already on medication for high blood pressure. We can check your specific drugs with the tool on this page.
What are the side effects of GABA?
The most common ones reported are drowsiness, stomach upset, minor throat burning, muscle weakness, and nausea. One patient on GABA also reported a temporary loss of menstrual periods, though this is rare. A full safety picture hasn't been drawn yet.
Is GABA safe to take long-term?
We don't have good long-term safety data yet. It's generally well tolerated in the short term, but if you're thinking of taking it regularly for weeks or months, talk to your pharmacist first.
Can I take GABA while pregnant or breastfeeding?
There isn't enough safety information to know either way. Speak with your doctor or pharmacist about whether the unknown risks fit your situation.
