Silica is an essential mineral for health. The highest concentration of silica (silicon dioxide) is found in connective tissues, cartilage and skin, with skin and the epicuticle of the hair containing the most. This mineral strengthens collagen and elastin fibres and contributes to tissue elasticity. As the silica level of the skin diminishes with advancing age, the tissues become increasingly inelastic and brittle. silica is found in high concentration in the calcification sites of growing bone and healing bone fractures. The silicon content of arteries is significantly decreased in areas with atherosclerotic plaques. Interestingly, heart disease death rates are lowest in regions of england and finland where the silicon level of drinking water is highest. silica-ok provides organic silica to strengthen connective tissues, obtained from the horsetail plant, together with zinc, selenium, antioxidant vitamins and b-vitamins.IndicationsSilica is essential for production of collagen, a protein that maintains skin subtleness and elasticity.See all
