Is Zinc Picolinate Safe with Collagen Peptides?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Take zinc supplements and collagen peptides at separate times (at least 1 hour apart). Patients on immunosuppressive kidney medications should maintain adequate zinc levels and monitor accordingly.
Why this interaction occurs
Collagen peptides are rich in histidine and cysteine residues which can chelate zinc ions in the gastrointestinal tract, reducing zinc bioavailability. In transplant patients on calcineurin inhibitors already at risk for zinc deficiency, this interaction may be clinically meaningful.
Evidence
Evidence level: limited.
