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 at 500 mg per capsule. Ornithine is an amino acid your body makes naturally and can also obtain from protein-rich foods.
The capsule itself is made from cellulose and hypromellose (plant-based materials), with small amounts of purified water, magnesium stearate, and silicon dioxide as inactive ingredients to help with manufacturing and stability.
Does it work?
Moderate evidence
The evidence for L-Ornithine is mixed depending on what you're using it for. It's rated possibly effective for athletic performance — meaning there's some research suggesting it may help, but the evidence isn't yet solid enough to be certain.
For dry skin, insomnia, and periodontitis (gum inflammation), the evidence we hold is insufficient to say whether it works or not. If you're considering this for one of those other uses, talk with your pharmacist about what the current science shows.
How safe is it?
Some data gaps
L-Ornithine is generally well tolerated when used short-term. However, long-term safety hasn't been well studied, so we don't have solid data on what happens if you take it for months or years on end.
The safety data advises against use during pregnancy and while breastfeeding due to lack of adequate safety information. If you're pregnant, breastfeeding, or planning either, 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 L-Ornithine Hydrochloride. That doesn't mean none could occur in your individual situation, so mention this supplement to your pharmacist when filling any new prescriptions — they can flag any concerns specific to your medications.
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.
L-Ornithine may be worth considering if you're looking at athletic performance support and want an ingredient with a possibly effective rating. Because long-term safety isn't well established and pregnancy/breastfeeding safety data is limited, anyone in those categories should check with their pharmacist first.
No medication interactions are documented for this ingredient.
