HelloPharmacist Scorecard of PreProtein Natural Cherry Flavor by Kramer Novis
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: collagen peptides, which are a form of dietary protein derived from collagen. The remaining ingredients are water, various flavorings and sweeteners (including natural cherry flavor and sucralose), acids, and preservatives — these are inactive ingredients that give the liquid its taste and shelf stability.
Does it work?
Not established
Collagen peptides are possibly effective for aging skin and dry skin, according to the data we hold. For muscle strength, the evidence suggests it's possibly ineffective.
For acne and athletic performance, there isn't enough reliable evidence yet to rate whether it works.
How safe is it?
Well-documented data
Collagen peptides are generally well tolerated as a dietary protein. Side effects are mild and uncommon; those that do occur may include nausea, indigestion (dyspepsia), diarrhea, and gas, but these are rare.
The safety data for pregnancy and breastfeeding is limited. The facts advise checking with your doctor before using during pregnancy, and caution is suggested during breastfeeding because there's little safety information available.
Meds to double-check
No known interactions
No interactions are documented in our data for the collagen peptides in this product.
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 safety information is well characterized.
If you're interested in a collagen supplement for skin health, PreProtein Natural Cherry Flavor offers a single-ingredient option that's generally well tolerated. Pregnant or breastfeeding women should talk to their doctor or pharmacist first.
Since this is primarily a dietary protein, it's not likely to interfere with medications, but always check with us if you're on a prescription.
