HelloPharmacist Scorecard of L-Ornithine 500 mg by Bluebonnet
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
This product contains one active ingredient: L-ornithine hydrochloride 500 mg per capsule. Ornithine is an amino acid that your body can make on its own, and it plays a role in immune function and wound healing.
The capsule also holds several inactive ingredients — cellulose, hypromellose, purified water, magnesium stearate, and silicon dioxide — which are common binders, thickeners, and flow agents used to hold the supplement together.
Does it work?
Moderate evidence
L-ornithine is possibly effective for athletic performance according to the evidence we hold. For other uses — dry skin, insomnia, and periodontitis (gum disease) — there isn't enough reliable evidence in our data to rate whether it works.
If any of those other uses interest you, talk with your doctor or pharmacist about whether the current evidence supports trying it for your situation.
How safe is it?
Some data gaps
L-ornithine is generally well tolerated in short-term use, but long-term safety hasn't been well studied, so we don't have solid data on what happens with extended supplementation. The safety data advises against use during pregnancy and while breastfeeding due to insufficient information.
If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this supplement.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we hold on file. That doesn't guarantee none exist, so check your exact medications with the tool on this page, and talk with your doctor or pharmacist if you have any concerns about adding this to your routine.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
This supplement may be worth considering if you're looking to support athletic performance, though evidence is still limited. Long-term safety data is thin, so it's best as a short-term option.
If you're pregnant, breastfeeding, or have questions about whether it fits your health picture, check in with your doctor or pharmacist before you start.
