Saw Palmetto (Serenoa repens) Berry Extract — 360 mg (yielding 162 mg Fatty Acids) Saw Palmetto berry extract, standardized to 45% free fatty acids, delivers the primary bioactive lipophilic fraction responsible for its well-characterized 5-alpha reductase inhibitory and anti-androgenic activity in follicular tissue. The free fatty acid content — particularly lauric, oleic, and myristic acids — competitively inhibits both type I and type II isoforms of 5-alpha reductase, reducing the intrafollicular conversion of testosterone to the more potent dihydrotestosterone (DHT) that drives progressive follicle miniaturization and androgenic alopecia in both male and female pattern hair loss. At 360 mg per serving yielding 162 mg of standardized fatty acids, this formula delivers a meaningful clinical dose of the DHT-reducing botanical most extensively studied for hair loss support, forming the hormonal cornerstone of this formula's multi-mechanism anti-androgenic approach.
MSM (Methylsulfonylmethane) — 200 mg MSM is a naturally occurring organosulfur compound and one of the most bioavailable dietary forms of elemental sulfur — the third most abundant mineral in the human body and an irreplaceable structural component of keratin, the fibrous protein constituting approximately 95% of hair fiber composition. Adequate organic sulfur availability from MSM directly supports the cross-linking of cysteine disulfide bonds within the keratin polypeptide chains that confer tensile strength, elasticity, and structural integrity to individual hair fibers — with sulfur deficiency associated with weaker, more brittle hair with increased breakage tendency. MSM additionally supports scalp health by promoting blood flow to the dermal papilla — the vascular structure at the base of each hair follicle responsible for delivering oxygen and nutrients to actively dividing follicle matrix cells — and contributes sulfur substrate to collagen synthesis in the scalp dermis that provides the structural scaffolding for follicle anchorage.
L-Cysteine — 200 mg & DL-Methionine — 500 mg L-Cysteine and DL-Methionine are the two sulfur-containing amino acids that serve as the direct structural building blocks for keratin biosynthesis and the primary determinants of hair fiber quality and strength. L-Cysteine provides the cysteine residues that form the disulfide bonds responsible for the mechanical strength and cross-linking density of the keratin matrix — with higher cysteine content producing stronger, more resilient hair fibers — while simultaneously serving as the rate-limiting precursor for glutathione synthesis in scalp and follicle tissue, protecting actively dividing follicle cells from oxidative damage. DL-Methionine — the sulfur-containing essential amino acid — is transsulfurated to cysteine in the methionine cycle, providing the primary metabolic source of cysteine for keratin synthesis when dietary cysteine is insufficient, while additionally supporting collagen biosynthesis in the scalp dermis through its role as the methyl group donor for S-adenosylmethionine (SAMe) in collagen methylation reactions. Together, these two sulfur amino acids provide the full structural amino acid complement for keratin and collagen synthesis in hair fiber, follicle, and scalp tissue.
Grape Seed Extract — 200 mg (yielding 190 mg Proanthocyanidins) Grape seed extract standardized to 95% oligomeric proanthocyanidins (OPCs) supports hair follicle health through two primary mechanisms: capillary-strengthening activity in scalp microvasculature and direct growth factor-mediated follicle stimulation. Proanthocyanidins support the structural integrity of capillary endothelium in the scalp dermal microcirculation by cross-linking collagen fibers within capillary walls and inhibiting hyaluronidase — the enzyme that degrades the connective tissue matrix surrounding follicle blood vessels — ensuring optimal blood flow, oxygen, and nutrient delivery to the dermal papilla of each hair follicle. Research has additionally demonstrated that proanthocyanidins from grape seed promote the transition of hair follicles from the telogen (resting) to anagen (active growth) phase through upregulation of vascular endothelial growth factor (VEGF) and β-catenin signaling in follicle dermal papilla cells — providing a growth factor-mediated mechanism that directly supports active hair follicle proliferation.
