USES:Calcium is the most abundant mineral in the human body and it is vital for bone and teeth growth as well as cell membranes, muscular contraction and immunity.

Calcium absorption is increased in the presence of vitamin D and lactose found in dairy as well as during pregnancy and lactation.

Calcium absorption is reduced by diets high in oxalates and phytates, steroid use and high intake of caffeine. A diet very high in protein may promote calcium urine loses.

Magnesium is important for calcium absorption as it plays an important role in vitamin D metabolism.

Rickets, osteomalacia, osteoporosis, tooth decay, brittle nails and insomnia are possible symptoms of calcium deficiency.

Food sources of calcium include dairy, kale, broccoli, fish with bones (sardines and canned salmon), wholegrains which also include good levels of magnesium and aid calcium absorption, nuts and seeds, beans and pulses.
