The formula targets six biological pathways relevant to skin health, hair growth and nail strength.
Biotin at 5,000 mcg supports keratin synthesis — the structural protein in hair and nails. This is the most commonly studied dose in peer-reviewed hair/nail research.
Vitamin C is a required cofactor for collagen production. At 20 mg (22% DV), Gelagen’s dose is modest but present. B6 supports amino acid metabolism feeding collagen pathways.
Vitamins C and E work synergistically to neutralize free radicals that damage skin lipids. Vitamin E is in the natural d-alpha form with higher bioavailability.
Folate and B12 (methylcobalamin) support DNA synthesis in rapidly dividing skin, hair follicle and nail matrix cells.
Pantothenic acid (B5) supports the coenzyme A pathway involved in skin barrier lipid production.
Iodine supports thyroid hormones that regulate growth cycles for skin, hair and nails. Zinc supports wound healing and skin integrity.
Skin cell turnover: ~28 days. Nail growth: ~3 mm/month. Hair growth: ~1 cm/month. These are biological ceilings no supplement can override.
