BioSil® combines ch-OSA® (choline-stabilized orthosilicic acid) with selenium to support the body's own collagen-generating pathways, plus antioxidant defenses that contribute to skin elasticity, hair resilience, and joint tissue maintenance. ch-OSA® is the clinically studied form of bioavailable silicon designed to activate collagen-producing cells rather than simply supplying collagen directly.
Why It's Worth Considering: The ch-OSA® complex uses choline as a carrier to significantly enhance orthosilicic acid absorption compared to standard silica sources, and the addition of selenium supports cellular protection against oxidative stress.

More category questions
How much selenium should I take?
For maintenance: 100-200mcg daily (selenomethionine form preferred). For thyroid support: 200mcg. The RDA is 55mcg but most functional medicine practitioners recommend 100-200mcg. Do NOT exceed 400mcg/day — selenium has a narrow therapeutic window and excess causes selenosis (hair loss, nail brittleness, GI issues).
Is selenium good for thyroid?
Yes — selenium is critical for thyroid function. It's required for the enzyme that converts inactive T4 to active T3, AND it protects thyroid cells from oxidative damage. In Hashimoto's, 200mcg selenium daily reduces TPO antibodies by 20-40% in clinical trials. It's one of the most evidence-based supplements for thyroid health.
Can I just eat Brazil nuts instead?
One Brazil nut contains 70-90mcg selenium — so 2 nuts/day provides a therapeutic dose. However, selenium content varies dramatically by soil (some nuts have 10mcg, others have 300mcg). If you rely on Brazil nuts, be cautious about overconsumption — 4-5 large nuts could exceed 400mcg. A supplement provides a consistent, known dose.
