Product Overview


  • Dietary Supplement
  • Amino Acid Chelate with Vitamin D-3

Calcium and magnesium work together in several key physiological processes. They are important in the regulation of blood pressure and are responsible for healthy muscle function. Calcium is needed for muscle contraction and magnesium for muscle relaxation. In addition, they are both components of skeletal tissue and magnesium is necessary for calcium's absorption into the bones.

Nice Calcium & Magnesium supplement with a side of Vit D

Posted by iHerb Customer on May 12, 2014 | Verified Purchase

These are perfect for someone looking for a lower dose of Magnesium and Calcium with an added bonus of Vit D. The only draw back is that the pills are very large and could be difficult to swallow whole. But you could break them up if needed.

Thanks for your feedback!
