Silicon is found in high concentrations in skin and nails and can help to strengthen hair. It also appears to play a part in building strong bones. Food sources include flaxseed, steel cut oats, almonds, peanuts and kelp, to name just a few. Horsetail Grass (also called Shavegrass) is naturally high in silicon. I think a colloidal preparation is easiest to absorb.
