Hydrolyzed Marine Collagen — 2,500mg This is the research dose. Clinical studies showing measurable nail improvement used 2,500mg of bioactive collagen peptides. Most supplements contain 100–500mg and call it a collagen product. This formula delivers the minimum effective threshold — the amount your nail matrix can actually use to build new plate layers.
Biotin (Vitamin B7) — 15,000mcg The highest clinically studied dose for nail thickness. Research shows 15,000mcg increases nail plate thickness by 25% and reduces splitting in 63% of brittle nail sufferers. Most standalone biotin supplements at this dose cause cystic acne — which is why this formula includes three specific ingredients to prevent that (see Zinc, Hyaluronic Acid, Irish Sea Moss below).
Beet Root Extract — 150mg A nitric oxide precursor. It dilates blood vessels and improves peripheral blood flow to the extremities. This is Phase 1 — before any ingredient can rebuild your nail, it has to get there. After 45, reduced estrogen measurably slows circulation to the fingertips. Beet Root opens that pipeline.
Vitamin B12 + Folate Support red blood cell production so the bloodstream is actively carrying nutrients to the nail matrix. These are the delivery system for everything else in this formula.
Keratin (Hydrolyzed) — 300mg Pre-formed structural protein. Your body rebuilds nails using both raw materials (collagen) and finished components (keratin). This formula supplies both simultaneously — faster matrix recovery than collagen alone.
Zinc — 15mg Clinically documented anti-inflammatory. Specifically included to suppress the sebum overproduction that high-dose biotin causes. This is why you can take 15,000mcg of biotin in this formula without the breakouts.
Hyaluronic Acid — 100mg Floods dermal layers with moisture, counteracting the drying effect that causes biotin-related oil overcompensation. Skin protection during the rebuilding window.
Irish Sea Moss — 500mg Contains natural sulfur — an antibacterial compound that keeps pores clear while biotin is at full dose. The third layer of skin protection. Also delivers 92 essential minerals your body uses in cellular repair.
Vitamin C — 180mg Without Vitamin C, your body cannot synthesize collagen regardless of how much you take. It's the cofactor that makes the 2,500mg dose actually work. Taking collagen without Vitamin C is like trying to build a wall with bricks but no mortar.
