Silica is a trace mineral which is vital in the development and formation of collagen. It provides strength and elasticity to all connective tissue and cartilage. As we age, the silica levels in our body becomes depleted, which could result in wrinkles, dry skin, unhealthy looking hair, brittle nails and bones. HealthAid uses bamboo extract which provides a superior quality, high strength source of natural silica, which helps maintain healthy hair, skin, nails and joints.
