Testosterone is downstream of biology, not willpower
Sleep, sunlight, training and micronutrient status determine the ceiling. Alpha Vitality is built to remove the most common biological brakes on healthy testosterone production.
Tongkat Ali (Eurycoma longifolia)
Standardised Tongkat Ali extracts have been shown in placebo-controlled trials to reduce SHBG and raise free testosterone, particularly in men under chronic stress. The 400:1 extract concentration is what the clinical literature uses.
Fadogia Agrestis
Animal data suggests Fadogia upregulates luteinizing hormone signaling. Human data is still emerging — we cycle it within a complete formula rather than rely on it alone.
Zinc, D3, Magnesium
The micronutrient floor. Prasad et al. (Nutrition, 1996) showed mild zinc restriction reduced serum testosterone by up to 75% in 20 weeks. Pilz et al. (2011) showed D3 supplementation raised testosterone by ~25% in deficient men.
Fenugreek, Maca, KSM-66®
Traditional vitality botanicals with growing clinical support, paired with KSM-66 ashwagandha to lower the cortisol that suppresses testosterone in the first place.
