Support optimal wellness with a highly absorbable form of zinc. Zinc supports general wellness, promotes healthy connective tissue, and helps maintain eye and reproductive health. If there was a super mineral, then zinc would be a contender. Zinc is an essential micronutrient that is crucial to more than 200 enzymatic reactions and plays a key role in growth, immune function, testosterone metabolism, and numerous other functions in your body. If the body has trouble absorbing a nutrient, then it can't obtain the nutrient’s benefits. Thorne offers two highly absorbable forms of zinc: Zinc Picolinate and Zinc Bisglycinate. Zinc Picolinate is zinc that is bound to the organic acid picolinic acid, which is naturally made in the body from the amino acid L-Tryptophan. Zinc Bisglycinate is zinc that is bound to two molecules of the amino acid glycine – creating a true amino acid chelate.
