Bamboo is an edible grass that has been part of mankind's diet for thousands of years. It is also the principal food for many species of mammals. The Indian elephant is smaller than its African cousin, but is much stronger. The Giant Panda of China exists almost exclusively on bamboo and its skeletal system is incredibly strong, yet very flexible. These unique properties are believed to be related in some part to the high silica content of bamboo. Bamboo extract is the richest source known of natural silica, containing over 70% organic silica. That is ten times the level found in the widely used Horsetail plant (Equisetum) which contains about 5% to 7% silica. Bamboo Silica extract is prepared from the Tabashir bamboo stem from India (Bambusa vulgaris). Silicon is the 2nd most abundant element on earth after oxygen. It is now known to play a part in the integrity of the skin, ligaments, tendons, and bone. The body constantly metabolizes silicic acid. Silica is eliminated from our bodies via natural processes including hair loss, nail trimming, and urination. This natural secretion of silica can be from 10 to 40mg daily. The average adult body contains about 20 grams of silica, and it needs to be maintained at this level to promote good health. As we age, less silica is assimilated; therefore daily supplementation with Bamboo Silica will help maintain the necessary equilibrium, and minimize the effects of premature aging. To further enhance the effectiveness of Enerex Bamboo Silica, the formula includes 200mg of calcium citrate. Calcium absorption is enhanced by the presence of silicon, and like silicon, calcium is involved in normal bone development. Calcium also has a role to play in regulating heartbeat, in energy production, immune function, and cell membrane permeability. Like silicon, a deficiency of calcium may speed skin aging.
