Silicon supplement by Ray Sahelian, M.D. health benefit of silicon supplement
On planet Earth, silicon is the second most abundant element (after oxygen) in the crust. In the form of silica and silicates, silicon forms useful glasses and ceramics. At this time it is not clear which medical conditions would be helped by adding a silicon supplement. For more research in this area, consider signing up to a free email Newsletter.
Silicon and hair thickness
Effect of oral intake of choline-stabilized orthosilicic acid on hair tensile

Silicon has been suggested to have a role in the formation of connective
tissue and is present at 1-10 ppm in hair. Choline-stabilized orthosilicic acid
is a bioavailable form of silicon which was found to improve skin microrelief
and skin mechanical properties in women with photoaged skin. The effect of
Choline-stabilized orthosilicic acid on hair was investigated in a randomized,
double blind, placebo-controlled study. Forty-eight women with fine hair were
given 10 mg silicon a day in the form of Choline-stabilized orthosilicic acid
beadlets or a placebo, orally for 9 months. Hair morphology and tensile
properties were evaluated before and after treatment. Urinary silicon
concentration increased significantly in the Choline-stabilized orthosilicic
acid supplemented group but not in the placebo group. The cross sectional area
increased significantly after 9 months compared to baseline in Choline-stabilized
orthosilicic acid supplemented subjects but not in the placebo group. The change
in urinary silicon excretion was significantly correlated with the change in
cross sectional area. Oral intake of Choline-stabilized orthosilicic acid had a
positive effect on tensile strength including elasticity and break load and
resulted in thicker hair.
Jarrow silicon
Los Angeles-based Jarrow Formulas is adding BioSil, a form
of silicon to its product line. In addition to its 30 ml liquid and 30-capsule size, Jarrow
introduced BioSil in a 60-capsule size. Each BioSil capsule in both the 30- and
60-capsule sizes has 5 mg of silicon as a stabilized, concentrated orthosilicic
acid per Vegi-cap. BioSil Caps is the encapsulated version of the patented
liquid concentrate of stabilized orthosilicic acid. The company claims
Stabilized orthosilicic acid is Biologically Active Silicon because it is the
only form of silicon absorbed directly through the stomach wall and the
gastrointestinal tract into the bloodstream. More research is needed with
silicon to determine if the claims by Jarrow Formulas is correct regarding
BioSil to be the only form of silicon absorbed directly through the stomach wall
and gastrointestinal tract.
Jarrow Formulas silicon supplement BioSil contains a
choline-stabilized and concentrated form of orthosilicic acid, ch-OSA. This
product was tested on hair thickness, strength and elasticity and the results
were presented by University of Cincinnati College of Pharmacy Professor R.
Randall Wickett at the Fifth International Congress of Hair Research held in
Vancouver Canada on June 13-16, 2007. An international research team conducted a
9-month, randomized, double-blind placebo controlled study using 48 healthy
Caucasian women with fine hair and an average age of 43 years. Half the women
supplemented their regular diet with 10 mg of silicon in the form of choline-stabilized
orthosilicic acid, while the other half received a placebo. The BioSil group
experienced an improvement over the placebo group including:
- Increased cross sectional area of hair fibers: 7.8 percent increase average
(twice the placebo group)
- Increased diameter of hair fibers: 3.8 percent increase average (1.7 percent
for the placebo group).
- Hair tensile strength and elasticity decreased significantly in the placebo
group (- 10.8 %) whereas in the BioSil group no significant change was observed.
“This is a rigorously controlled study demonstrating that the oral intake of a
dietary supplement may improve hair quality,” says Randy Wickett, Ph.D,
Professor and Director of the Cosmetic Science Program at the University of
Cincinnati. “Hair tensile properties such as strength and elasticity may degrade
over time because of exposure to sunlight or other factors. In this study the
intake of choline-stabilized orthosilicic acid increased the diameter of the
hair and reduced the loss of elasticity and tensile strength compared to
placebo.”
BioSil contains a choline-stabilized and concentrated form of orthosilicic acid,
ch-OSA and is manufactured by Bio Minerals n.v. in Destelbergen, Belgium.

Silicon questions
Q. Any thoughts on the safety and/or effectiveness of orthosilicic acid
supplements such as Jarrow Biosil? I ask because I've read organic silicon can
help improve skin texture and hair quality but I am concerned about toxicity.
Any thoughts would be most helpful.
A. We have not seen any significant human research with
orthosilicic acid, silicon supplements or Jarrow Biosil, hence we don't have a
strong opinion on this supplement at this time.
