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.

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 4 active ingredients: L-glutamine, GABA (gamma-aminobutyric acid), L-tyrosine, and DL-phenylalanine. L-glutamine is an amino acid that supports recovery and immune function.

GABA is a neurotransmitter involved in relaxation and nerve signaling. L-tyrosine is another amino acid that serves as a building block for neurotransmitters and thyroid hormones.

DL-phenylalanine is an amino acid compound. The capsule itself is made from vegetable material.

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 support.
  • We looked for evidence on: Anxiety, Attention deficit-hyperactivity disorder (ADHD), Cognitive function, Depression, Fatigue, Insomnia — 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 Anxiety, Attention deficit-hyperactivity disorder (ADHD), Depression, Insomnia, and more.

Evidence for this product's effectiveness is limited and mixed. L-tyrosine is possibly effective for cognitive function and memory, and effective for the rare metabolic condition phenylketonuria (PKU).

The other ingredients have insufficient reliable evidence to rate them for mental attitude or mood support — meaning the science hasn't established whether they work for those purposes in the way this product markets them. GABA, for example, shows insufficient evidence for anxiety, despite common claims about its calming role in the brain.

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

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 is rated likely safe in pregnancy and lactation. However, all four ingredients carry cautions about long-term safety — the data is incomplete.

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. GABA and L-tyrosine aren't recommended during breastfeeding because there isn't enough safety information.

Common side effects across the ingredients include headache, nausea, and gastrointestinal upset like bloating, constipation, or diarrhea. At higher doses, L-glutamine has been linked to dizziness and, rarely, mania in people with bipolar disorder.

GABA may cause drowsiness or muscle weakness.

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?
  • 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're on any of the following: seizure medications (anticonvulsants), blood pressure medications (antihypertensives), levodopa for Parkinson's disease, thyroid hormones, sedatives or sleep aids (CNS depressants), or any psychiatric medications. These are the medication types documented to interact with ingredients in this product.

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.

If you take seizure medications, blood pressure medications, Parkinson's medication (levodopa), or thyroid hormones, you'll want to talk with your doctor or pharmacist before starting this product. Even if you don't take those specific drugs, the interaction data is substantial — check your full medication list with the tool on this page.

L-glutamine and L-tyrosine are generally well tolerated, but long-term safety for all four ingredients isn't well established, and evidence that they improve mood or mental attitude is lacking.

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.

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 or liver problems?
L-glutamine is generally well tolerated, but if you have kidney or liver disease, it should only be used under medical supervision. Talk to your doctor before taking this product.
Can I take this while breastfeeding?
There isn't enough safety information for GABA or L-tyrosine during breastfeeding, and the product label advises caution. L-glutamine is rated likely safe, but the overall product carries a caution. Discuss it with your doctor or pharmacist before starting.
What are the most common side effects?
The most common side effects reported across the ingredients are headache, nausea, and gastrointestinal issues like bloating, constipation, and diarrhea. At higher doses, you might experience dizziness or drowsiness.

Is there a risk of mania or mood disturbance?
Mania and hypomania have been reported in two patients with bipolar disorder taking glutamine at high doses. If you have bipolar disorder, mention this product to your doctor before starting.
