THE SCIENCE BEHIND KYN
Most supplement companies underdose ingredients or hide behind proprietary blends. You pay premium prices for compounds that barely register.
KYN is built for men reclaiming what's been stripped away—by chronic stress, microplastics in your bloodstream, toxins in your food and water, endocrine disruptors in everyday products, and a culture that profits from your decline. Every ingredient is dosed at clinically meaningful levels because half-measures don't restore what's been lost.
The formulation targets the complete spectrum: testosterone optimization, cardiovascular health, cognitive function, recovery, and stress resilience. Everything that drives integrated performance.
Below you'll find the research foundation with direct study links. Complete transparency on what's included and why. The science speaks for itself.
Shilajit (500mg) • Vitamin D3 (125μg) • Vitamin K2 MK-7 (100μg) • Complete micronutrient matrix
Shilajit Extract (25% Fulvic Acid, 500mg)
Testosterone support: 90-day double-blind RCT in healthy men using 500mg daily (250mg twice daily) increased both total and free testosterone plus DHEA-S vs placebo, without changing LH/FSH. Study
Sperm quality: 90-day trial in oligospermic men improved sperm count, motility, and other parameters. Study
Exercise performance: 8-week RCT using 500mg daily promoted retention of maximal muscular strength following fatiguing exercise and decreased baseline hydroxyproline (collagen degradation marker). Study
Mineral absorption: Shilajit contains fulvic acid as its main active component (~60-80% of total compound), which enhances mineral bioavailability by forming complexes with minerals, making them more soluble and improving their transport across cell membranes. This "yogavaha" effect in Ayurvedic medicine acts as a synergistic enhancer of other nutrients.
Bone health: 48-week RCT in postmenopausal women with osteopenia showed dose-dependent preservation of bone mineral density at both 250mg and 500mg daily, with reduced bone turnover markers and inflammation. Study
Vitamin D3 (125μg / 5,000 IU)
Immune function: Large individual-participant meta-analysis of 25 RCTs found vitamin D supplementation reduced acute respiratory infection risk, especially in deficient individuals with daily/weekly (non-bolus) dosing. Study
Musculoskeletal performance: Meta-analyses show strength benefits primarily when correcting deficiency. Adequate vitamin D is essential for calcium absorption, muscle function, and testosterone synthesis.
Safety note: High-dose supplementation. Monitor serum 25-OH-D levels.
Vitamin K2 MK-7 (100μg)
Arterial health: 3-year double-blind RCT using 180μg daily improved arterial stiffness indices and reduced inactive matrix Gla protein (dp-ucMGP) in postmenopausal women, indicating improved vitamin K-dependent vascular protein activation. Study
Calcium regulation: Works synergistically with vitamin D3 to ensure calcium is deposited in bones rather than soft tissues.
Complete Micronutrient Matrix
Boron (5mg): Human studies show increased free testosterone, decreased SHBG, and reduced inflammatory markers (hsCRP, TNF-α) within days of supplementation. Study
Zinc (30mg) + Copper (2mg): Zinc is essential for Leydig cell steroidogenesis and testosterone synthesis. Marginal zinc deficiency consistently lowers testosterone levels. Copper inclusion prevents zinc-induced copper deficiency during long-term use. Study
Selenium (200μg): Critical cofactor for glutathione peroxidase enzymes (cellular antioxidant defense) and thyroid hormone metabolism via deiodinase enzymes. Deficiency impairs both antioxidant capacity and thyroid function.
Vitamin A (500μg) + Beta-Carotene (1,000μg): Essential for testosterone synthesis, immune function, and vision. Beta-Carotene provides additional antioxidant protection and serves as vitamin A precursor.
Vitamin E (200mg α-tocopherol): Primary fat-soluble antioxidant protecting cell membranes from lipid peroxidation. Works synergistically with selenium in antioxidant enzyme systems.
Iodine (150μg): Essential component of thyroid hormones T3 and T4. Deficiency leads to hypothyroidism, affecting metabolism, energy, and cognitive function.
Manganese (5mg): Cofactor for manganese superoxide dismutase (Mn-SOD), a critical mitochondrial antioxidant enzyme. Also required for collagen synthesis and bone formation.
Chromium (200μg): Enhances insulin sensitivity and glucose metabolism through activation of insulin signaling pathways.
