Silicon is a trace mineral essential for collagen synthesis, bone mineralization, and connective tissue formation.
The best-absorbed form is orthosilicic acid (OSA), BioSil® / Regensil® brands.
A 2005 RCT found OSA (10mg/day, 20 weeks) increased femoral BMD by 2% and improved skin elasticity, hair thickness, and nail brittleness.
Silicon concentration in connective tissue is 200-600 μg/g, higher than iron. Beer is the richest dietary silicon source (due to barley processing). Dose: 5-10mg/day as OSA.
