Calcium citrate

Calcium citrate, supplied though not directly manufactured by NINGBO PANGS CHEM CO., LTD., is a widely used dietary supplement notable for not requiring stomach acid for absorption, making it well-suited to older adults and those on acid-reducing medications like proton pump inhibitors. The supplier describes it as helping prevent and treat calcium deficiency conditions such as osteoporosis, rickets, and osteomalacia while supporting muscle contraction, nerve transmission, blood clotting, and heart rhythm, though it notes potential interactions with thyroid hormones, certain antibiotics, and bisphosphonates that warrant spacing doses apart. Samples are available, and it is distributed to markets across the Americas, Europe, Australasia, Asia, the Middle East, and Africa.
