HelloPharmacist Scorecard of 100% Pure L-Ornithine 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

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: L-Ornithine Hydrochloride, a form of the amino acid ornithine. That's it — the label says there are no inactive ingredients or fillers.

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

This product doesn't appear to be marketed for a specific use, so we graded Ornithine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Ornithine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Athletic performance — rated "Possibly Effective" (Natural Medicines).

The evidence supports ornithine's use for athletic performance, where it's rated possibly effective. For dry skin, insomnia, and periodontitis (gum disease), there isn't enough reliable research yet to say whether it works.

The evidence, ingredient by ingredient Ornithine

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

L-Ornithine is generally well tolerated in the short term, but we don't have good long-term safety data, so caution is warranted if you're thinking of using it regularly over months. The safety data advises against taking it during pregnancy or while breastfeeding — there simply isn't enough information to know it's safe for your baby.

Side effects, ingredient by ingredient Ornithine

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for L-Ornithine.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and some safety-information gaps remain.

If you're looking to support athletic performance, ornithine may be worth trying. If you're pregnant, nursing, or planning long-term use, talk to your pharmacist or doctor first to weigh what we know against your own health situation.

Does 100% Pure L-Ornithine by NutraBio interact with any medications?
We do not currently list a known interaction for the mapped ingredients in 100% Pure L-Ornithine. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
100% Pure L-Ornithine 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.
Does L-Ornithine actually help with athletic performance?
The evidence suggests it possibly helps — that's the best-supported use we have on file. If you're considering it for workouts or training, it may be worth trying, but results aren't guaranteed.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against it — there isn't enough information to know it's safe for your baby. Talk to your doctor or pharmacist about your specific situation before starting.
Are there any side effects?
No side effects are documented in our data. It's generally well tolerated in the short term, though long-term safety hasn't been studied carefully.
Does it help with insomnia or dry skin?
There isn't enough reliable evidence yet to say whether it works for either of those. The research just isn't there to support or rule it out.
What exactly is L-Ornithine Hydrochloride?
It's a form of the amino acid ornithine — a building block your body uses for various functions. The hydrochloride is just the salt form that makes it stable and easier to use as a supplement.
