Nutra BioGenesis Tri Zinc delivers zinc in three complementary, highly bioavailable forms — providing comprehensive zinc replenishment that a single-form zinc supplement cannot match. Formulated for healthcare practitioners seeking precise, high-quality zinc supplementation. 90 capsules.Zinc is an essential trace mineral required as a cofactor for over 300 enzymatic reactions including immune T-cell function, testosterone synthesis, DNA polymerase and RNA transcriptase activity, wound healing, antioxidant enzyme (SOD) activity, and insulin signaling. Zinc deficiency is the most prevalent micronutrient deficiency in the world. Tri Zinc combines zinc picolinate (highest bioavailability, absorbed in the small intestine), zinc citrate (good bioavailability with GI tolerability), and zinc bisglycinate chelate (gentle, well-absorbed amino acid chelate) — providing complementary absorption pathways for more complete replenishment than any single form. Nutra BioGenesis is a physician-grade supplement brand formulated exclusively for healthcare practitioners, providing pharmaceutical-quality clinical nutrition supplements with independent testing and clean formulations. Available at Beauty Riche — authorized retailer with same-day shipping.
