Planet Paleo Pure Collagen

Bone broth, raw kefir/yogurt, tahini or sesame, nettle tea, and tinned sardines with bones. Calcium should come with a matrix.

Homemade bone broth simmered long enough to gel; chicken feet or trotters when appropriate; grass-finished gelatin strips; collagen from real animal parts, not a dessert-flavored powder pretending to be ancestral.

Whole pastured eggs, wild fish, organic meat, raw Greek yogurt, skyr, bone broth, and local grass-fed dairy protein when food is realistic.
