Overview Information

Silicon is a naturally occurring mineral. Many foods including water, beer, coffee, and some vegetables naturally contain silicon. Silicon supplements are also used as medicine.

Silicon is used for weak bones (osteoporosis), heart disease, aging skin, and other conditions, but there is no good scientific evidence to support most of these uses.

Do not confuse silicon with silicone. Silicone is the name of a group of materials resembling plastic that contain silicon, oxygen, and other chemicals. Silicone is used to make breast implants, medical tubing, and a variety of other medical devices.

How does it work?

A clear function of silicon in humans has not been established. There is some evidence, though, that silicon might have a role in bone and collagen formation.


Uses & Effectiveness?

Possibly Effective for

  • Weak and brittle bones (osteoporosis). Men and younger (pre-menopausal) women who get more silicon from their diet seem to have stronger bones, which could reduce the risk of weak bones. But higher silicon intake does not seem to benefit older (post-menopausal) women unless. These women tend to develop weak bones because their bodies continually break down bone. Silicon doesn't seem to stop the bone breakdown. It promotes only bone formation.

Insufficient Evidence for

  • Aging skin. Early research shows that taking a specific silicon product by mouth might improve skin firmness and texture but not wrinkles or skin brightness.
  • Alzheimer disease.
  • Digestion problems.
  • Hair loss.
  • Heart disease.
  • Sprains and strain.
  • Other conditions.
More evidence is needed to rate the effectiveness of silicon for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Silicon is LIKELY SAFE in food amounts. There isn't enough information to know if silicon is safe when used as a medicine.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Silicon is LIKELY SAFE when used in food amounts. Its safety in larger medicinal amounts is unknown. Stay on the safe side and avoid use.

Surgical removal of the stomach (gastrectomy): Silicon values may be lower in patients who have had their stomachs surgically removed.



We currently have no information for SILICON Interactions.



The following doses have been studied in scientific research:



  • For weak and brittle bones (osteoporosis): Eating a diet that includes 40 mg of silicon seems to be linked with stronger bones than lower doses.
Currently, there is no recommended dietary allowance (RDA) for silicon.
