Youtheory: price per serving
This site tracks 10 listings from Youtheory across 2 categories: Hair, skin & collagen, Protein. Every price below is normalized to cost per serving so packages of different sizes can be compared directly.
Most of the Youtheory listings tracked here are collagen products in the hair, skin and collagen category, sold as capsules, powders, and liquids. The catalog also carries one whey protein powder from the brand that is marketed under a GLP-1 support name.
That last point is worth pausing on. A product name that references GLP-1 does not change what the product is. Read the ingredient panel and the protein content, then compare it against the other protein powders in the tracker on cost per serving rather than on the name.

What this page does not tell you
- Nothing about product quality. Price per serving is a cost normalization. This site does not test products, assess ingredient quality, or verify manufacturing claims.
- Nothing about whether a supplement is appropriate for you. That is a conversation for your prescriber, particularly if you take other medications.
- Nothing about products sold outside Amazon. The catalog covers Amazon listings only, so a brand may sell products that never appear here.
How these numbers are calculated is documented in full on the methodology page.
