Increases phosphocreatine stores in muscle, directly fuelling ATP resynthesis during explosive efforts. More ATP available means more reps completed before fatigue sets in.
EPA and DHA reduce pro-inflammatory cytokines (IL-6, TNF-α), accelerating muscle repair between sessions. Also directly incorporated into joint cartilage, reducing stiffness and pain.
Magnesium regulates NMDA receptors and GABA activity — both critical for sleep onset and muscle relaxation. The glycinate form has superior absorption vs oxide. Exercise depletes magnesium 2× faster than sedentary living.
Beta-alanine raises muscle carnosine levels — the primary buffer against lactic acid accumulation. Higher carnosine delays the pH drop that causes muscular failure during sustained high-intensity efforts.
Vitamin D3 activates VDR receptors in muscle tissue and testosterone-producing Leydig cells. K2 directs calcium to bone rather than arterial walls. Over 40% of adults in northern Europe are clinically deficient.
Hydrolysed collagen peptides taken 30–60 minutes pre-exercise flood the bloodstream during the post-exercise collagen synthesis window. Vitamin C is an essential co-factor for hydroxyproline synthesis — the amino acid that gives collagen its tensile strength.
Raises plasma arginine levels, increasing nitric oxide production and vasodilation. Simultaneously reduces ammonia accumulation in muscle — the primary cause of acute fatigue during resistance training.
Binds MT1/MT2 receptors in the suprachiasmatic nucleus, lowering core body temperature — the primary physiological trigger for sleep onset. Non-habit-forming at doses of 0.5–3mg.
Withanolides in KSM-66 modulate the HPA axis stress response, reducing cortisol secretion. Elevated cortisol — from training and life stress — breaks down muscle tissue and impairs sleep.
Zinc is a rate-limiting cofactor in testosterone synthesis and immune cell production. The bisglycinate form has significantly higher bioavailability than zinc oxide. Athletes lose substantial zinc through sweat — a hard session can deplete 2–3mg, pushing below the threshold for optimal testosterone output.
Athletes have significantly elevated micronutrient demands due to increased metabolic rate, sweat loss, and cellular turnover. A comprehensive multivitamin closes the gaps that even a well-structured diet leaves — particularly B vitamins for energy metabolism, zinc for testosterone, and antioxidants for oxidative stress from training.
