                                 Dietary Minerals 

Dietary Minerals are the group of minerals which is essential for our body to sustain normal functions and physical health.

                                      Calcium

Calcium, a trace mineral plays an important role in build and maintain strong bones and teeth, found abundantly in meat, poultry, fish, nut, seeds, bean, etc. As we age, calcium is absorbed less effectively.

     BK Channels in Cardiovascular Diseases and Aging
Aging is a major risk factor for cardiovascular diseases, one of the main world-wide causes of death. Several structural and functional changes occur in the cardiovascular system during the aging process and the mechanisms. BK channels are transmembrane proteins that play a key role in many physiological processes, including regulation of vascular tone.In vascular smooth muscle cells, BK opening and the consequent efflux of potassium (K(+)) leads to membrane hyperpolarization, which is followed by the closure of voltage-dependent Ca(2+) channels, reduction of Ca(2+) entry and vasodilatation. BK regulates nitric oxide-mediated vasodilatation and thus is crucial for normal endothelial function(13).
