Does BioSil Strengthen Hair, Skin and Nails? -- Bottle of BioSil

Answer:

Silica (silicon dioxide) is a form of the element silicon that is used as a food additive to keep ingredients flowing during manufacture. It is also the building block of quartz and is abundant in sand.

A bioavailable form of silicon, known as orthosilicic acid (which is, essentially, silica with attached water molecules) is naturally found in a variety of foods and beverages and is a key ingredient in BioSil, a dietary supplement that includes choline and has been promoted as "clinically proven to increase collagen formation, increase skin elasticity, reduce wrinkles, thicken and strengthen hair, increase bone collagen formation, and increase bone mineral density." However, the evidence supporting these claims has weaknesses, and there is a possible safety concern with one of the compounds in BioSil.

Products sold as "silica supplements" typically contain either orthosilicic acid or natural plant ingredients that contain it or other natural chemical forms of silicon.

Why would choline increase cardiovascular risk? I thought choline was essential for things like brain health.

I know someone who has used BioSil for 15 years (on & off) and found that it really does make a difference in the softness of fingernails. The person is a "nail biter" when nervous.
After taking the liquid daily, added to pull-apart "00" capsules for three weeks, the nails would tear off evenly in a straight line. Without the BioSil, the nails tear partially straight and vertically.

I wonder about taking just silicon, such as Life-Flo Silica Drops which I take once a day. 6 drops of that has only 6 mg silica, so maybe it's not enough to make a difference?
