What is the recommended dosage for Silicon (Silica)?

General: 10-25 mg/day bioavailable silicon; Skin Hair Nails: 5-10 mg ch-OSA per day

What are the side effects of Silicon (Silica)?

Potential side effects include: Generally well-tolerated, Mild gastrointestinal discomfort (rare).

What is silicon (silica) and how may it support skin health?

Silicon is a trace element involved in collagen cross-linking and glycosaminoglycan formation in connective tissue. Orthosilicic acid (bioavailable silicon) supplementation has been studied for skin, hair, and nail health. Clinical trials suggest silicon may improve skin roughness and strengthen hair and nails.

What dosage of silicon has been studied for skin benefits?

Clinical trials have used 5–10 mg of bioavailable silicon per day as choline-stabilized orthosilicic acid (ch-OSA, branded as Biosil/Regensil). Studies lasted 8–20 weeks. Silicon from horsetail extract and colloidal silica has lower bioavailability. The ch-OSA form has the best clinical evidence.

What are the potential side effects of silicon supplements?

Oral silicon supplements are generally well tolerated at studied doses. Mild digestive discomfort has been reported. Long-term safety data is limited. Crystalline silica (different from dietary silicon) is a known carcinogen when inhaled, but this does not apply to oral silicon supplements.

About

Silicon is a trace mineral involved in collagen cross-linking and glycosaminoglycan synthesis. An RCT found ch-OSA (10 mg/day for 20 weeks) significantly improved skin roughness and hair brittleness. Dietary silicon intake has declined with modern food processing.

How It Works

Trace mineral involved in collagen cross-linking and glycosaminoglycan synthesis; supports connective tissue formation by activating prolyl hydroxylase; choline-stabilized orthosilicic acid (ch-OSA) is the most bioavailable supplemental form.
