Detailed Breakdown
Why it works: Zinc picolinate (30mg/day): cofactor for 5α-reductase, aromatase inhibitor, androgen receptor function. T increase most significant if baseline deficient.
Recommended intake: 15-30mg/day picolinate or glycinate
Why it works: Leydig cells express VDR. D3 supplementation increases total T by ~25% in vitamin D deficient men.
Recommended intake: 2000-5000 IU/day + K2 100μg
Why it works: 6mg/day reduces SHBG significantly → increases free T by 28% and decreases estradiol by 39% in 60 days.
Recommended intake: 6-10mg/day
Why it works: Reduces cortisol → reduced T suppression. Increases DHEA-S. 5g/day root powder increased T by 17% in stressed men.
Recommended intake: 300-600mg KSM-66 daily
