Feeding Collagen
Skin builds collagen from raw materials you eat: adequate protein, vitamin C, and zinc are non-negotiable inputs; collagen peptide supplements show promising but industry-heavy evidence.
How it works
Collagen synthesis requires glycine and proline (from dietary protein) and vitamin C as an essential cofactor for cross-linking enzymes — frank deficiency literally stops wound healing. Trials of hydrolyzed collagen peptides report modest gains in skin elasticity and hydration, though many are industry-funded; food-first covers the fundamentals either way.
The practice
Daily: a palm of protein at each meal, one vitamin-C-rich food (citrus, berries, peppers, amla), zinc sources (seeds, legumes, eggs). Bone broth and slow-cooked cuts are the traditional collagen kitchen.
The tradition
Nutritional dermatology; traditional broth cookery
