Colloidal Silica for Hair, Skin and Nails

By on October 24, 2016

Silicon levels have been discovered to decrease with age. Silica is a compound primarily comprised of silicon, a trace mineral that is found in our bodies in the form of silicic acid or silanate. 

Although no recommended daily intake has been established for silicon, deficiencies are known to impact the hair, joints, nails and skin.

Silica is being studied as a possible adjunctive treatment for osteoporosis because of its association with improved bone mineral density. Silicon supplementation may improve the condition of hair, nails and skin in some people.

Silicon levels have been discovered to decrease with age. While it is found in many commonly consumed foods such as bananas, string beans, rice and barley, the degree of dietary absorption can be highly variable.
Colloidal silica is readily absorbed from the intestinal tract. In fact, its degree of absorption has made it appealing as a possible delivery mechanism for poorly-absorbed medications. 

Because silicon can build up in the body if you have impaired kidney function, please consult your MD or ND before taking a supplement if you have renal disease.

Silica Facts
• Silicon is an essential trace element derived from silica and required for the formation and maintenance of connective and other bodily tissues.
• Silica is most commonly found in nature as sand or quartz and is not normally bioavailable
• Colloidal silica is a more pure and potent source of silicon than the herb horsetail Equisetum arvense
• Silicon increases tissue levels of hydroxyproline, one of the key amino acids required for the synthesis of collagen 
  and elastin, components of bone, sinew and muscle
• Silicon improves some health parameters such as firmness and strength of the connective tissues, cartilage and the skin, nails, and hair
• Silica is not silicone which is an inert, synthetic compound that is typically heat-resistant and rubber-like with a variety of forms and industrial uses
