HelloPharmacist Scorecard of Agmatine 500 mg by OL Olympian Labs

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 one active ingredient: agmatine sulfate, which is a compound your body produces naturally and that's also found in some foods. The rest of the capsule is made up of inactive ingredients — hydroxypropyl methylcellulose, ascorbyl palmitate, microcrystalline cellulose, silica, and rice flour — that help hold the capsule together and protect the powder inside.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Agmatine product and its label doesn't state a use — see Agmatine's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for agmatine isn't established yet. Our data shows insufficient reliable evidence to rate it for alcohol use disorder, Alzheimer disease, anxiety, athletic performance, autism spectrum disorder, bipolar disorder, and several other uses.

That doesn't mean it doesn't work — it means we don't have enough solid human studies to say one way or the other.

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 appears generally well tolerated. The most common side effects reported in studies were diarrhea, upset stomach (dyspepsia), and nausea — and a small number of trial participants experienced mild-to-moderate diarrhea and nausea within a few days of starting it, which went away once they stopped.

Long-term safety in humans hasn't been well studied, so we don't know what happens with extended use. There isn't enough safety data to recommend agmatine during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist about whether it's right for you in those situations.

Side effects, ingredient by ingredient Agmatine

Meds to double-check

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 — Agmatine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 258 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, double-check with your pharmacist if you're on any blood pressure medications (Moderate interaction) or diabetes medications (Moderate interaction). Either one could have its effect changed by agmatine.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Agmatine may be worth considering if you're interested in trying it for one of the uses we've listed, but the evidence isn't solid yet. If you take blood pressure or diabetes medication, check with your pharmacist before starting — this product could affect how those drugs work.

Short-term side effects are mild and usually go away, but long-term safety is unknown.

Agmatine 500 mg by OL Olympian Labs: Common Questions

Does Agmatine 500 mg by OL Olympian Labs interact with any medications?
Yes. Based on its ingredients, Agmatine 500 mg has a known interaction with 258 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Agmatine 500 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.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way, so it's best to avoid agmatine during pregnancy and while breastfeeding. Talk with your doctor or pharmacist for personalized advice about your situation.
What side effects might I get?
The most common ones reported in studies were diarrhea, upset stomach, and nausea. A small number of people in trials experienced mild-to-moderate diarrhea and nausea within 2–3 days of starting, and these effects went away once they stopped taking it.
Is this safe to take long-term?
Short-term use appears generally well tolerated, but long-term safety in humans hasn't been well studied. If you're thinking about taking it for weeks or months, talk with your pharmacist.
What is agmatine and what's it supposed to do?
Agmatine is a compound your body makes naturally and that's also in some foods. Our data shows insufficient evidence to rate it reliably for several uses, including anxiety, cognitive function, and athletic performance — meaning we don't have enough solid studies to say whether it works.
Does this product have any fillers?
Yes — the capsule contains inactive ingredients like microcrystalline cellulose, rice flour, silica, and others that help hold it together.
