Zinc SAP 60 Softgels

Zinc Picolinate Supplement with Copper for Immune, Skin, and Metabolic Support

NFH Zinc SAP delivers 25mg of zinc as zinc picolinate per capsule — the amino acid-chelated form of zinc where zinc is bound to picolinic acid (a natural metabolite of the amino acid tryptophan) that facilitates zinc transport across intestinal epithelial cells via a ligand-mediated uptake mechanism. Comparative bioavailability studies have shown zinc picolinate to produce superior plasma zinc levels and tissue retention compared to zinc gluconate and zinc citrate, and dramatically superior absorption compared to zinc oxide, which is the cheapest and most commonly used zinc form in mass-market supplements despite its notoriously poor bioavailability (often below 5%).

Zinc is involved in the function of over 300 enzymes and 1,000 transcription factors throughout the body, making it one of the most functionally important trace minerals in human physiology. Its role in immune function is particularly well-documented: zinc is required for thymic hormone production and T-cell maturation, NK-cell cytotoxicity, neutrophil function, cytokine signaling, and the maintenance of the intestinal mucosal barrier that serves as a frontline immune defense. NFH includes 1mg of copper from copper citrate in each capsule specifically to maintain the healthy zinc-to-copper balance that long-term zinc supplementation requires — an important safety consideration frequently overlooked in single-mineral zinc products.

• Zinc picolinate 25mg per capsule — ligand-mediated uptake for superior bioavailability
• Copper citrate 1mg — maintains zinc:copper ratio; prevents copper depletion
• Supports T-cell development, NK-cell function, and mucosal immune defense
• Connective tissue, skin, and metabolic enzyme support
• 60 capsules; non-GMO, gluten-free, soy-free

Take 1 capsule daily with food, or as directed by your healthcare practitioner.
