+ All FAQs

Who should take Biosil®?

Biosil® can be beneficial for everyone. Collagen production typically peaks around age 21, and levels decline an average of 1% per year thereafter, though degradation rates vary with genetics and lifestyle factors.
People usually observe the effects of collagen loss in their skin, hair and nails, and feel the changes in their bones and joints. Biosil® helps rejuvenate these collagen-dependant tissues at any age.†
When should I expect results with Biosil®?

1 month: Faster growing nails are one of the first improvements people say they notice.†
2 months: More voluminous, faster-growing, and lustrous hair is commonly reported in the second month.†
3 months: Glowing, brighter, more luminous skin can happen within three months for some people, according to reviews.†
3 months: Biosil® reduces joint discomfort, increases mobility and range of flexibility, and improves cartilage condition after three months, according to a clinical study.†
4-5 months: Biosil® significantly improves wrinkles and fine lines, as well as skin elasticity in this timeframe, according to a clinical study.†
4-6 months: Biosil® reduces nail brittleness after four months, and reduces vertical lines and roughness after six, according to a clinical study.†
9 months: Biosil® strengthens, thickens, and elasticizes hair after nine months, according to a clinical study.†
12 months: Biosil® increases bone collagen production, and improves bone density at the hip, according to a clinical study.†
Can I trust these clinical trials?

Meaningful proof of Biosil®’s effects on skin, hair, nails, bones, and joints comes from randomized, double-blind, placebo-controlled human clinical trials published in top peer-reviewed medical journals—the highest standard for clinical testing.
There is a major difference between the phrases "clinically proven" and "clinically tested." Any product can be tested in a clinical setting, but only those products that show statistically significant results may use the phrase "clinically proven." Biosil® is clinically proven in double-blind, placebo-controlled clinical trials.
