Zinc Picolinate

Zinc picolinate supports over 100 enzymes involved in immune function and wound healing, and reduces cold symptom duration by 33% when taken within 24 hours of onset, according to a Cochrane review. This outperforms #8 Methylfolate in acute immune response, offering superior absorption via picolinate chelation. A daily dose of 15–30 mg addresses subclinical deficiency affecting 2 billion people worldwide, providing 20% better bioavailability than zinc gluconate.
