HelloPharmacist Scorecard of GABA 500 mg by Bluebonnet
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
This product contains 2 active ingredients. Vitamin B6 (pyridoxine) is a B-complex vitamin that supports nerve function and metabolism.
GABA (gamma-aminobutyric acid) is a neurotransmitter your brain naturally produces. The capsule also contains inactive ingredients—cellulose, hypromellose, purified water, and magnesium stearate—that help hold the product together.
Does it work?
Not established
The evidence varies by ingredient. Vitamin B6 is effective for treating sideroblastic anemia and vitamin B6 deficiency, and it's been shown effective for a rare seizure disorder called pyridoxine-dependent epilepsy.
It's likely effective for high homocysteine levels (a heart risk factor) and possibly effective for pregnancy-related nausea. GABA, however, doesn't have reliable evidence behind it for any of the conditions commonly used for—including anxiety, ADHD, athletic performance, and cerebral palsy.
The data we hold shows insufficient evidence to rate it.
How safe is it?
Well-documented data
Vitamin B6 is well tolerated in doses under 100 mg daily. Common side effects at higher doses can include headache, nausea, heartburn, and loss of appetite.
At very high doses (over 1,000 mg daily or long-term high intakes), it can damage nerves, causing tingling or weakness—a condition called sensory neuropathy. GABA appears generally well tolerated short-term, with reported side effects including drowsiness, nausea, muscle weakness, and mild throat irritation.
Long-term safety of GABA hasn't been well studied. There isn't enough safety data on either ingredient during pregnancy or breastfeeding to know whether they're safe, so talk with your doctor or pharmacist before use if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Double-check this product before taking it if you're on phenobarbital or phenytoin (seizure medications)—vitamin B6 at high doses may reduce how well they work. Also screen blood pressure medications, amiodarone (heart rhythm medication), and levodopa for Parkinson's disease.
If you take sedatives, sleep aids, or drink alcohol regularly, discuss the possible additive drowsiness from GABA.
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.
This product works best for people with vitamin B6 deficiency or specific medical conditions like sideroblastic anemia—and for that, talk to your pharmacist about dosing. If you take seizure medications, blood pressure drugs, or levodopa for Parkinson's, check your medications against our tool before starting.
The GABA component lacks solid evidence for the conditions it's often marketed for, so know what you're buying.

GABA 500 mg by Bluebonnet Drug Interactions
HelloPharmacist Interaction Report
Bluebonnet's GABA 500 mg contains two active ingredients, and both can interact with medications.
Vitamin B6 has the most serious documented interaction: it may reduce the blood levels and effects of phenobarbital and phenytoin (seizure medications) at high doses, potentially making these drugs less effective.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 can also have additive blood-pressure-lowering effects with antihypertensive drugs (a Moderate concern), might worsen photosensitivity from amiodarone, and may speed up the metabolism of levodopa (a Parkinson's medication) when taken without carbidopa. GABA itself can theoretically add to the blood-pressure-lowering effects of antihypertensive medications and may increase drowsiness when combined with central nervous system depressants (sleep aids, sedatives, alcohol), though the clinical relevance of the GABA interaction is unclear.
Altogether, these interactions span 423 individual medications. Before you start this product, use the medication checker on this page to search your exact prescriptions.

For each ingredient in GABA 500 mg 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.
Gamma-Aminobutyric Acid
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.
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.
Vitamin B6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
