Zinc Picolinate

MODERATE EVIDENCEMineralLast updated

AVELOR SUMMARY

Zinc picolinate has 4x greater absorption than zinc gluconate and 2x greater than zinc citrate in a 1987 comparison study. Picolinic acid (a tryptophan metabolite) is the body's natural zinc-binding ligand for intestinal absorption. Dose: 15-30mg elemental zinc. The original Barrie 1987 study is the primary evidence for superior bioavailability. Some experts dispute the magnitude of absorption advantage. Regardless: well-absorbed and well-tolerated. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
