HelloPharmacist Scorecard of L-Proline Powder by Source Naturals
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-proline, an amino acid your body uses in collagen and connective tissue. There are no inactive ingredients listed for this powder.
Does it work?
Not established
The evidence we hold does not establish that L-proline works for athletic performance, bone health (osteoporosis, osteopenia, or fracture prevention), or wound healing. The available data is rated insufficient to say whether it helps with any of these uses.
If you're considering it for a specific health goal, talk it over with your doctor or pharmacist about whether the current evidence supports trying it.
How safe is it?
Some data gaps
L-proline is generally considered low-risk when eaten in food, but the safety of taking it as a supplement in extra amounts has not been well studied. The data we hold does not give us reliable information on what dose is safe to use, so it's best to avoid supplemental amounts unless your doctor advises otherwise.
There isn't enough reliable data on whether L-proline is safe to take while breastfeeding. If you are pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist about whether this supplement is right for you.
Meds to double-check
No known interactions
No interactions are documented in our data for L-proline. If you take any medications, you can confirm there are no concerns using the search tool on this page, or check with your own doctor or pharmacist before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and some safety-information gaps remain.
L-proline is an amino acid with no documented drug interactions, so timing with medications is not a concern. However, the evidence does not yet establish that it works for athletic performance, bone health, or wound healing, and supplement safety at higher doses hasn't been well studied.
If you're thinking about using it, discuss your reason and dose with your doctor or pharmacist to make sure it fits your health plan.
