I've recently discovered a new brand of protein powder named (Nutrabolics IsoGainer, 5LB)?

Question

Its just that, for some reason, when I saw the nutrition facts and compared them all with a few other webpages, some shows (Calcium 390mg) and some dosen't.

Please if anyone knows the real answer please tell me.

Answer 1

Some protein powders have added extracted milk minerals (calcium) to their products, which is a highly bioavailable form of calcium without the fat & lactose of dairy products.  It also contains other minerals & nutrients like magnesium, phosphorus, potassium, & zinc, which are needed for optimal bone formation & metabolism.

A higher calcium intake can also reduce high blood pressure.  

The reason bodybuilders and other athletes like having added calcium to their protein supplements is because a higher calcium intake leads to reduced body fat levels and helps shift metabolism to increased lypolysis (fat burning), and decreases lipogenesis (fat storage).
