Food-derived protein-based calcium chelates: digestive stability, intestinal transport, and bone-related functions
Conventional calcium supplements often show limited bioaccessibility and suboptimal gastrointestinal tolerance. Food-derived proteins, protein hydrolysates, and peptide–calcium chelates have been investigated as protein-based calcium chelates. This review organizes these systems along a structural continuum from protei...
