Premier Reseach Labs Liquid Zinc Ultra is Highly Absorbable Liquid Zinc. Zinc is a critical micronutrient, but the type of zinc in supplements can influence the impact on the body. Many zinc supplements on the market are formulated with zinc oxide or zinc carbonate, which are poorly absorbed and nearly insoluble. In contrast, Liquid Zinc Assay is made with zinc sulfate heptahydrate, a hydrated form of zinc sulfate, that is water soluble. This highly absorbable form of zinc is designed to provide healthy zinc supplementation.
