HelloPharmacist Scorecard of PMA Positive Mental Attitude by Viva Vitamins

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

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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

PMA Positive Mental Attitude contains four active ingredients. L-Glutamine is an amino acid used to support recovery from illness and physical stress.

GABA (gamma-aminobutyric acid) is a neurotransmitter your brain uses to promote relaxation. L-Tyrosine is another amino acid that supports brain function and mood.

The product also contains DL-Phenylalanine, which we cannot verify for you. The capsule itself is made from vegetable cellulose.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: mental alertness, focus, mood, and motivation.
  • We looked for evidence on: Attention deficit-hyperactivity disorder (ADHD), Cognitive function, Depression, Fatigue, Memory, Psychological well-being — and 4 related terms.
  • The strongest evidence on file: Tyrosine is rated "Possibly Effective" for Cognitive function (Natural Medicines).
  • Also on file: Tyrosine is rated "Possibly Effective" for Memory.
  • Also on file: Gamma-aminobutyric Acid (gaba) is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD), Depression, Post-traumatic stress disorder (PTSD), Psychological well-being.

The evidence behind these ingredients is mixed. L-Glutamine is effective for sickle cell disease and shows possible benefit for muscle wasting in HIV/AIDS, recovery after surgery, and critical illness from trauma.

L-Tyrosine is effective for phenylketonuria (PKU) and possibly effective for focus and memory — though it appears ineffective for athletic performance. GABA has insufficient evidence for the conditions it's marketed for, including anxiety, ADHD, and athletic performance.

We hold no effectiveness data for DL-Phenylalanine.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-Glutamine and L-Tyrosine are generally well tolerated in healthy adults, though people with kidney or liver disease should use L-Glutamine only under medical supervision. Common side effects from L-Glutamine include bloating, constipation, diarrhea, nausea, and headache.

L-Tyrosine may cause fatigue, headache, heartburn, and nausea, especially at higher doses. GABA is often tolerated short-term, but long-term safety isn't well studied.

It may cause drowsiness, nausea, muscle weakness, and minor throat irritation. Rare cases of mania have been reported with high-dose glutamine in people with bipolar disorder.

Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Gamma-aminobutyric Acid (gaba), Glutamine, Tyrosine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: seizure medications; Parkinson's medications.
  • For scale: 440 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 product if you use anticonvulsant medications (seizure drugs), antihypertensive drugs (blood pressure medications), levodopa (Parkinson's medication), thyroid hormone medications, or CNS depressants (sedatives, sleep aids, anxiety medications). L-Tyrosine and levodopa doses should be separated by at least 2 hours if you take both.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to someone looking for a brain-support blend, but the evidence for most of its ingredients is thin or absent. If you take anticonvulsants, blood pressure medications, Parkinson's medication, thyroid hormone, or any sedating drugs, you'll want to discuss this product with your doctor or pharmacist first — the interaction risks are real, even if some haven't been seen in humans yet.

People with kidney, liver, or bipolar disorder should talk to their healthcare provider before starting.

GABA2 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.

Likelihood Unlikely Evidence D
GABA full monograph & interactions

L-Glutamine1 drug type · 50 drugs

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

Likelihood Possible Evidence D
L-Glutamine full monograph & interactions

L-Tyrosine2 drug types · 21 drugs

Levodopa

Theoretically, tyrosine might decrease the effectiveness of levodopa.
Tyrosine and levodopa compete for absorption in the proximal duodenum by the large neutral amino acid (LNAA) transport system. Advise patients to separate doses of tyrosine and levodopa by at least 2 hours.

Likelihood Probable Evidence D
Thyroid Hormone

Theoretically, tyrosine might have additive effects with thyroid hormone medications.
Tyrosine is a precursor to thyroxine and might increase levels of thyroid hormones.

PMA Positive Mental Attitude by Viva Vitamins: Common Questions

Does PMA Positive Mental Attitude by Viva Vitamins interact with any medications?
Yes. Based on its ingredients, PMA Positive Mental Attitude has a known interaction with 440 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
PMA Positive Mental Attitude contains 4 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 L-Glutamine safe if I have kidney disease?
No — if you have kidney or liver disease, you should only use L-Glutamine under close medical supervision. Talk to your doctor before starting this product.
Can I take this while pregnant or breastfeeding?
L-Glutamine is rated likely safe in pregnancy. However, there isn't enough safety data for GABA and L-Tyrosine during pregnancy, and GABA should be avoided while breastfeeding. There's insufficient data for L-Tyrosine while breastfeeding. Talk to your doctor or pharmacist about whether this product is right for you.
Will this actually help my anxiety?
The evidence for GABA to treat anxiety is insufficient — we don't have reliable data showing it works. Your best bet is to discuss anxiety management with your doctor or pharmacist.
What are the most common side effects?
From L-Glutamine you might experience bloating, constipation, diarrhea, nausea, or headache. L-Tyrosine may cause fatigue, headache, heartburn, or nausea. GABA may cause drowsiness, nausea, or muscle weakness.
Can I take this long-term?
L-Glutamine and L-Tyrosine are generally well tolerated, though you should check with your doctor before regular use. GABA's long-term safety hasn't been well studied, so short-term use is what we know most about.
