HelloPharmacist Scorecard of Agmatine 90 G by NutraBio

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 12, 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 powder contains one active ingredient: agmatine sulfate. Agmatine is a naturally occurring compound that forms in your body from the amino acid arginine.

There are no other inactive ingredients — what you see is what you get.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle and exercise performance support.
  • We looked for evidence on: Athletic performance, Muscle strength, Muscle pumps, Nitric oxide, Workout recovery.
  • The closest evidence on file: Agmatine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Agmatine is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

The evidence we hold on agmatine doesn't yet establish whether it works for the conditions it's marketed for. We have insufficient reliable evidence to rate it for alcohol use disorder, Alzheimer disease, anxiety, athletic performance, autism spectrum disorder, and bipolar disorder.

If you're considering it for one of these, talk with your doctor or pharmacist about what the current research actually supports.

The evidence, ingredient by ingredient Agmatine

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.

Short-term use of agmatine appears generally well tolerated, but long-term safety in humans hasn't been well studied, so we don't know what happens if you take it for months or years. The most common side effects reported in clinical studies are diarrhea, indigestion (dyspepsia), and nausea — these showed up in a small number of participants within 2–3 days of starting and resolved once they stopped.

There isn't enough safety data for pregnancy or breastfeeding, so the data advises against use during both. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

The bottom line

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

Agmatine is a single-ingredient supplement that's generally well tolerated short-term, but anyone on blood pressure or diabetes medications should check their specific drugs first — the interaction risk is real. Long-term safety isn't established, and it's not recommended in pregnancy or while breastfeeding.

Talk with your pharmacist before starting, especially if you take medications.

How can one product interact with so many drugs?
Agmatine 90 G 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 exactly is agmatine?
Agmatine is a compound your body naturally makes from the amino acid arginine. This supplement gives you a concentrated dose of it as agmatine sulfate powder.
What side effects has agmatine caused in studies?
The most common ones are diarrhea, indigestion, and nausea. In the studies we have, these appeared within a few days of starting and went away once people stopped taking it.
Is agmatine safe to take long-term?
Short-term use appears generally well tolerated, but long-term safety in humans hasn't been well studied, so we don't know what happens if you use it for extended periods.
Can I take agmatine while pregnant or breastfeeding?
There isn't enough safety data to say it's okay, so the data advises against it during both pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice.
Does agmatine actually work for anxiety or Alzheimer disease?
We don't have enough reliable evidence yet to say whether it works for those or the other conditions it's marketed for. The research isn't established in the data we hold.
