Silicon is a naturally occurring mineral. It's the second-most abundant element on earth after oxygen. Food sources include water, fruits, and vegetables.

Silicon supplements are sometimes used as medicine. It's not clear if silicon has a function in the human body. But there's some evidence it might have a role in forming bone and collagen.

People use silicon for weak bones (osteoporosis), aging skin, and many other conditions, but there is no good scientific evidence to support most of these uses.

Do not confuse silicon with silicone. Silicone is a group of materials resembling plastic that are used to make medical devices.
When taken by mouth: Silicon is commonly consumed in foods. There isn't enough reliable information to know if silicon is safe when used as a medicine.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Silicon is commonly consumed in foods. There isn't enough reliable information to know if it's safe to use as medicine or what the side effects might be. Stay on the safe side and stick to food amounts.

Surgical removal of the stomach (gastrectomy): Silicon levels in the blood might be lower in people who have had their stomachs surgically removed.
