Calcium and Marine Collagen can be taken together. Any benefit from combining them rests on limited evidence. Marine collagen (5–10 g/day) can be taken at any time and with calcium. A bone benefit has not been shown.
No trial cited here tested marine collagen with calcium on bone density or fractures.
Marine collagen peptides (primarily type I) provide the hydroxyproline-proline sequences that stimulate osteoblast collagen synthesis, creating the organic scaffold for calcium-hydroxyapatite deposition. Marine collagen is rich in specific sequences (e.g., Pro-Hyp, Ala-Hyp) that are absorbed and detected by osteoblast receptors to promote bone matrix formation.
What to do: Marine collagen (5–10 g/day) can be taken at any time and with calcium. A bone benefit has not been shown.
