HelloPharmacist Scorecard of L-Proline 2,000 mg by Nutricost
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 to build and repair connective tissue like collagen. You're getting 2,000 mg per serving.
There are no inactive fillers or binders — it's proline powder only.
Does it work?
Couldn't assess
The evidence we have doesn't establish that L-proline reliably works for athletic performance, bone strength (osteoporosis, fractures, or osteopenia), or wound healing. That's not to say it does nothing — it means the reliable studies simply aren't there yet in the data we hold.
How safe is it?
Some data gaps
L-proline from food sources is generally well tolerated. Supplement safety at higher doses hasn't been well studied, so it's wise to stick with the dose on the label unless your doctor tells you otherwise.
There isn't enough reliable data on supplemental doses during breastfeeding, so if you're nursing, talk it over with your doctor or pharmacist before taking extra amounts.
Meds to double-check
No known interactions
No interactions are documented in our data for the medications we checked. Still, run your specific prescriptions and over-the-counter drugs through the search tool on this page before you start, or ask your pharmacist.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
L-Proline is an amino acid that plays a role in collagen, but we don't have solid evidence it works for the conditions it's often sold for. If you're thinking about adding it to support joints, bone, or recovery, it's worth discussing with your doctor or pharmacist to see if it makes sense for you.
Don't exceed the label dose without medical guidance.
