20 mg of natural Silica from Horsetail extract per tablet Vegetarian Supplement With Calcium, Magnesium and Zinc Futurebiotics Super Silica Complex is a vegetarian complex of silica from Horsetail leaf extract, minerals and select nutrients that nutritionally supports healthy bones, hair & nails* Silica (silicon) is required for proper integrity of the skin, ligaments, tendons, and bone. The highest concentrations of silicon in the body are found in skin and hair. As we age, skin levels of silicon decline. Research has shown that supplemental silicon can help support beautiful skin and healthier hair. In addition, research shows that silicon-deficient diets lead to depressed collagen synthesis and abnormal ligament, tendon, and bone integrity. Specifically, silicon is required by the enzyme, prolyhydroxylase, which is involved in collagen synthesis in bone, cartilage, and other connective tissues. Silicon is also believed to play a role in bone calcification as high concentrations of silicon have been found at the calcification sites of growing bones. Super Silica Complex provides 20 mg of natural silica from Horsetail leaf extract. Super Silica Complex is further enhanced with the minerals Calcium, Magnesium and Zinc. Calcium helps build strong bones and teeth. It is also an essential nutrient for the healthy function of the heart, nerves, blood and muscles. Magnesium plays a critical role in calcium metabolism. Low serum levels of magnesium have been found to result in hypocalcemia (low serum levels of calcium), which affects proper bone growth. Magnesium is also required for more than 300 biochemical reactions in the body. Zinc is an important nutrient for healthy skin, a vital component of many enzyme reactions and is required for protein synthesis and collagen formation.
