CELLFOOD Silica is designed to provide foundational support for bones, joints, muscles, and connective tissue. In our youth, our tissues absorb and maintain high levels of silica – enabling our bodies to remain flexible, resilient, and energetic. As we age, our body’s natural ability to produce silica steadily declines. Silica supplementation can be an aid in supporting healthy bones, joints and cartilage, skin, nails, hair, teeth and gums.
