Healthy hair: grow strong and beautiful hair.
BioSil® is clinically proven to help each strand of your hair grow stronger and thicker. By activating the collagen-producing cells in your body, BioSil® improves nutrient flow to the hair's root, and enlarges the root itself. It also helps bind the keratin fibers in each strand, which reduces fraying and split ends.†
Hair is 97% keratin, but it grows from collagen-based tissue in your skin. When your body produces enough collagen, each strand of hair grows from a larger, healthier root, and the result is thicker, more beautiful hair. However, around age 21 collagen levels start to decrease—going down by as much as 22% by age 78, according to one study. Low collagen in the scalp withers the root, and results in thinner, weaker hair that breaks more easily.†

Go to FAQ →- Thicker hair: BioSil® is clinically proven to thicken each individual strand of hair, which results in more volume overall.†
- Stronger hair: Your hair's strength comes from elasticity, which helps it resist damage from aging, styling, and environmental factors.†
Yes. There are no known contraindications between BioSil® and any other supplements.
BioSil® is not made from collagen, it generates collagen. When you ingest collagen your body breaks it down and digests it as food. Your body views collagen supplements like any other protein-rich meal: meat, seafood, poultry. In this way, many collagen supplements aren't very different from drinking a protein shake.
BioSil®, by contrast, turns on your body’s collagen-producing cells. In your skin, these cells are called fibroblasts. In bone, they’re called osteoblasts. When your fibroblasts and osteoblasts begin to slow down with age, collagen production diminishes. BioSil® has been clinically proven to increase collagen formation by supporting these cells, and helping them operate at full capacity. What’s more, BioSil® protects the newly formed collagen, as well as your existing collagen, from damage.†
BioSil® is clinically proven to help hair in several ways:

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.†
Yes. The biological processes Biosil® supports are identical in women and men. Biosil® generates and protects collagen, elastin, and keratin—it has absolutely no impact on sex hormones.†
Absolutely. BioSil® does not contain any animal-derived products whatsoever.
First, ch-OSA® triggers the production of new collagen, keratin, and elastin.†
Many collagen supplements are made of ground livestock (hooves, hide, scales, bones, and other meat byproducts), but even the plant-based or protein peptide supplements rely on the idea that you can increase your collagen levels by eating enough of it. However, when you eat collagen your body treats it like any other protein: it breaks it down and digests it as food. Instead of eating foreign, non-human collagen, taking ch-OSA® activates your own cells to produce fresh collagen, elastin, and keratin.†
Secondly, ch-OSA® also protects your existing collagen, keratin, and elastin from degradation.†
The choline in ch-OSA® is proven to neutralize homocysteine and regulate cortisol, two "anti-collagens" which destroy existing collagen and suppress new production. In this way, ch-OSA® protects existing elasticity and strength in your hair, skin, nails and bones.†
