Daily collagen peptide supplementation
The speaker reviews extensive evidence: a 2022 RCT showed improvements in wrinkles, roughness, elasticity, and moisture; a 2023 meta-analysis of 26 RCTs confirmed significant benefits for hydration and elasticity; four additional trials since 2023 all positive. The new bovine collagen study adds to this, showing 25% wrinkle reduction in 8 weeks. The speaker personally includes 12.5 grams of collagen peptides in his own supplement, Microvitamin Plus Powder. He addresses the criticism that collagen is just amino acids by citing the burn patient study where collagen peptides outperformed protein for wound healing, and the mechanistic data on peptide absorption and fibroblast stimulation. He concludes that collagen peptides are a science-backed, safe, and simple intervention for skin aging.
Collagen peptides are short chains of amino acids absorbed intact via peptide transporters in the gut. They reach the skin and signal fibroblasts to upregulate production of collagen, elastin, and proteoglycan, improving skin structure and hydration. This is distinct from merely providing amino acid building blocks; the peptides act as bioactive signaling molecules.
This is why I included 12 1/2 grams of collagen peptides in microvitamin plus powder. But just because I take a supplement does not in any way mean that you should as well.
Supplementing with collagen peptides has been shown to boost skin hydration and elasticity.
