Collagen Peptides
Vital Proteins (Nestlé) · For GLP-1 shedding · ~$27/bottle
Collagen peptides are popular and some people feel their hair and nails improve, while just as many notice no difference. The honest read from the community is that your body breaks collagen down into amino acids anyway, so for hair during GLP-1 shedding, hitting your overall protein target does more than a collagen scoop.
Who it is for
- You already enjoy it and want a general protein or skin supplement
Who it is not for
- You are buying it specifically to stop GLP-1 shedding
- You have not yet hit your daily protein target (do that first)
What users report
- Some users feel their hair and nails improve (user reviews)
- An easy way to add a little protein to a drink (user reports)
Complaints and concerns
- Just as many report no noticeable difference for hair (user reviews)
- It is digested into amino acids, so it is not hair-specific; total protein matters more (community consensus)
Before you try it
- For GLP-1 shedding, prioritize total daily protein over a collagen-specific product
Ingredients and proposed mechanism
Hydrolyzed collagen provides amino acids. There is little hair-specific evidence; it contributes to overall protein intake like any other protein source.
