The well-balanced formula provides a rich source of calcium with co-factors to help maintain strong bones and teeth, as well as the health of the heart, muscles, and nerves. The formula includes the full-recommended daily allowances of calcium and magnesium, which play a vital role in bone development, along with vitamin D3 and zinc. Vitamin D contributes to normal bone growth and development by helping the bones absorb calcium. It is also responsible for bone mineralisation and producing the hormones which maintain healthy levels of calcium and phosphorus levels in the bones and bloodstream. Suitable for vegetarians.
