One scoop here gives you 10g of **hydrolyzed bovine collagen** — squarely inside the 5–20g range used in clinical research, and at the top of the 2.5–10g window where studies show gains in skin elasticity, hydration, and wrinkle depth. The peptides are hydrolyzed into smaller fragments your body absorbs more readily, so for skin support you're getting a full, effective dose in a single daily serving with no pill burden.

Collagen is the only active here, so what you see is what you get. Your body uses vitamin C as a cofactor to build collagen, so taking this alongside a vitamin C source can help you make the most of those peptides. One caveat if you're sulfite-sensitive or asthmatic: the label lists sulfites among the other ingredients, which is worth knowing before you buy.

Natural and Artificial FlavorsFlavor

The 'artificial' component means synthetic chemicals are used, but the exact compounds are proprietary and not disclosed on the label. If you have sensitivities or allergies, you cannot verify what's in it. Products using only natural flavors are more transparent.

SulfitesPreservative

Sulfite sensitivity affects ~1% of the general population and up to 5% of asthmatics. Can trigger bronchospasm, hives, and anaphylaxis in sensitive individuals. FDA mandates labeling above 10 ppm.
