Hydrolyzed Collagen
Hydrolyzed Collagen Peptides 350 MG
Bovine source · bioactive peptides
Provides amino acids — especially glycine, proline, and hydroxyproline — that your body uses to build collagen, the structural scaffold in skin dermis, hair follicles, and nail matrices.*
Collagen peptides have been studied in randomized trials for their role in supporting skin elasticity, hair density, and nail growth as part of consistent daily intake.

MSM
MSM 50 MG
Methylsulfonylmethane · bioavailable sulfur
An organic sulfur compound your body uses to cross-link collagen and form the disulfide bonds in keratin — the structural framework of hair and nails. Sulfur is also a building block of the antioxidant systems active in skin and scalp cells.*
Clinically studied at 1–3g/day for hair and skin condition over 12 weeks or longer. Dose-dependent effects on hair shine, condition, and skin appearance documented in randomized supplementation studies.

Bamboo Silica
Bamboo Silica 15 MG
Bambusa arundinacea extract · bioavailable silicon
Silicon cross-links collagen fibers and supports the mineralization of hair and nail matrices. Bamboo is one of the most bioavailable natural sources of silica your body can absorb.*
Silicon supplementation has been studied in randomized trials for hair strand thickness, tensile strength, and nail resilience — commonly in combination with other nutrients.

Pumpkin Seed Extract
Pumpkin Seed Extract 50 MG
Cucurbita pepo · standardized phytosterols
Contains plant compounds, including phytosterols and lignans, that have been studied for their role in supporting 5-alpha reductase modulation — the enzyme pathway that converts testosterone to DHT, a hormone linked to pattern hair changes.*
Pumpkin seed has been studied in a 24-week randomized trial for its effect on hair count in men with pattern hair changes.

L-Cysteine
L-Cysteine 10 MG
Sulfur-containing amino acid
An amino acid your body uses to form the disulfide bonds in keratin — the chemical links that give hair its tensile strength. Roughly 10–15% of keratin is composed of cysteine residues. Also serves as a precursor to glutathione, an antioxidant active at the hair follicle.*
Clinically tested at 500–1,000mg/day in combination with keratin hydrolysate. Studies show improvements in hair density and tensile strength in cases of telogen effluvium over 8–12 weeks.

Biotin
Biotin 10,000 MCG
Vitamin B7 · keratin synthesis cofactor
An essential cofactor your body uses in keratin synthesis — the structural protein in hair and nails. Biotin supports normal hair, skin, and nail formation when daily intake is adequate.*
Included to ensure adequate daily intake. Clinical benefit is strongest in cases of biotin insufficiency; daily supplementation supports normal keratin production.
Hero shot placeholder
Vitamin C
Vitamin C 30 MG
Ascorbic acid · collagen synthesis cofactor
A required cofactor for the enzymes that cross-link and stabilize collagen. Without adequate vitamin C, your body can't properly assemble the collagen scaffolds that give skin its elasticity and hair follicles their structural support.*
Pairs synergistically with collagen peptides. Combination studies of collagen + vitamin C show greater effects on hair density and skin parameters than collagen alone.
Hero shot placeholder
Vitamin D3
Vitamin D3 35 MCG
Cholecalciferol · fat-soluble vitamin
Hair follicles express vitamin D receptors. D3 supports normal follicle cycling between growth and resting phases and helps modulate inflammatory signaling pathways linked to hair shedding.*
Mechanism documented in 2024 research on NLRP3 and HIF-1α pathways. Clinical evidence is strongest in individuals with vitamin D-associated telogen effluvium.
Hero shot placeholder
Vitamin E
Vitamin E 6 MG
Tocopherol · fat-soluble antioxidant
A fat-soluble antioxidant that protects the lipid membranes of skin cells and hair follicles from UV and environmental free radical damage. Works synergistically with selenium as part of the body's antioxidant defense system.*
50+ years of dermatological research supports vitamin E's role in photoprotection and protection of follicle cells from oxidative stress.
Hero shot placeholder
Zinc
Zinc 5 MG
Essential trace mineral · 300+ enzyme cofactor
Your body uses approximately 20mg of zinc daily to maintain hair follicle cycling. Zinc supports keratin synthesis, follicle stem cell signaling, and the antioxidant enzymes that protect dermal papilla cells.*
Cross-sectional research links zinc status to hair density. Daily replenishment supports normal follicle function and immune tolerance at the hair follicle.
Hero shot placeholder
Selenium
Selenium 25 MCG
Trace mineral · selenoprotein precursor
Incorporated into glutathione peroxidase — your scalp's master antioxidant enzyme that protects hair follicle stem cells from oxidative damage. Also supports thyroid hormone conversion, which regulates hair growth cycles.*
Dosed within the narrow therapeutic window (RDA 55µg, UL 400µg). Adequate intake supports selenoprotein synthesis and indirect thyroid-mediated hair cycling.
