What is Silica?

Silicon is the Earth's second most abundant element and a vital trace mineral for human health. It plays a key role in forming structural components of bone and connective tissues, such as collagen and elastin, which provide strength and elasticity to skin, blood vessels, and bones. Silicon is especially crucial in early bone mineralization and is concentrated in growth plates.

In the body, silicon is primarily present as silica, or silicon dioxide. This is a bioavailable form that supports collagen synthesis and connective tissue health. Natural health practitioners often recommend silicon for:

  • Bone strength
  • Cardiovascular health
  • Brain health
  • Potential to slow neurodegenerative aging

In essence, silicon becomes bioactive as silica, bridging the gap between the element and its beneficial roles in supporting structural and connective tissue in your body. 

The Difference Between Silicone & Silica

Not to be confused with silicone (the breast implant material), silicon is the inorganic mineral form of this atom, which is the type found in the soil. Silicon is commonly found bonded to oxygen in plants and animals, which is a form called silica or silicon dioxide. This is the organic and supplemental form that is available to our bodies.

Top Health Benefits of Silica

Strengthens Hair and Nails

When used topically, silica creams and gels are shown to benefit hair and nail strength. Supplementation thickens both hair and nails, and can be a simple way to solve problems with brittle growth. Unfortunately, if a deficiency was not the cause of the brittle hair and nails, silicon supplementation will not make a huge difference. If you do not see results in a few weeks, consult with your healthcare practitioner for other options.

Bone Formation

During your late teens and early 20’s, supplementing with silica can help to promote the synthesis of stronger bones. Unfortunately, this effect is only seen in growing bones, so there is less of an effect on bone health with silica supplementation in our later years.

Cognitive Protection and Aging

Silicon is thought to protect the body from aluminum accumulation. Silicon levels decline with age and a deficiency of silica may lead to degeneration of the vessels, bones and connective tissue that is commonly seen in the elderly. One 2008 study found that higher silica levels in water helped to reduce the risk of dementia by 11%.

Silicon and Wound Healing

There has been some recent research into the use of silicon gels in the treatment of wounds and burns to prevent excess scarring. The research is not conclusive, but this is an interesting area for further research.

How Can I Get More Silica?

It can be taken as a liquid or in capsules. Encapsulated silica supplements are usually made from the Horsetail herb, which naturally concentrates silica from the soil. Silicon is naturally abundant in the husks of grains and other high fibre foods, but is lost from foods during the refining process. Because this is only a trace mineral in the body, high doses are not necessary and may even cause problems. Stay within the recommended dosages.
