Calcium Osteo Complex

From a convenience perspective we decided to use Calcium Citrate when formulating this product because it contains the highest amount of elemental calcium by weight - around 40%.

While studies show Calcium Carbonate is a little easier to absorb, it only contains 21% calcium - meaning you would need to take more tablets to be able to hit your daily recommended calcium requirement.

Yes. Puro Calcium Complex was formulated to pair well with other products in range. It can be used alongside other supplements which do not already contain calcium.

Yes. Puro Calcium Complex is non-GMO & does not contain wheat or gluten.

We use Magnesium Citrate as it's gentler on your stomach (meaning less side effects), highly bioavailable & easier for your body to absorb (meaning better results).

Some researches shows the earlier you receive a good supply of calcium the better. Getting enough calcium is especially important:
For growing children, throughout pregnancy and breast-feeding, during and after the menopause, for elderly men and women and also for athletes and dancers. This supplement can be taken for as long required.
