The raw materials are l-aspartate and food-grade calcium hydroxide, adopting the advanced nano-chelating technology. Two amino acid molecules clamp one calcium atom to form a super-stable chemical structure, the absorption rate and the bioavailability of the human body (especially the bone) is particularly high, more than 90%. These features of calcium amino acid chelates are second to none. Absorption rate is higher than 90%. No need gastric acid hydrolysis, so the stomach is comfortable and no burden at all. No need vitamin d3.
