Testosterone & Hormones
Zinc, ashwagandha, vitamin D3 and the rest: what actually moves the needle.
L-Carnitine
Transports fatty acids into mitochondria and supports testosterone receptor activity.
Zinc
Essential mineral: deficiency directly suppresses testosterone production.
Ashwagandha
Adaptogenic herb that lowers cortisol and raises testosterone in stressed men.
Vitamin D3 + K2
Essential for testosterone synthesis: most UK men are deficient, especially in winter.
Boron
Trace mineral that reduces SHBG and increases free testosterone.
Tongkat Ali
South-east Asian root with clinical evidence for testosterone and libido in men.
Fadogia Agrestis
Nigerian shrub showing testosterone-boosting potential, but limited human data.
Magnesium Glycinate
The most under-supplemented mineral for testosterone, sleep, and muscle recovery.
DHEA
Precursor hormone that declines sharply with age: supplementation is prescription-only in the UK.
Apigenin
Natural flavonoid that promotes deep sleep and inhibits oestrogen conversion.
Panax Ginseng
Ancient adaptogen with solid evidence for energy, cognition, and erectile function.
Probiotics
Live bacteria that support gut microbiome diversity, immune function, and hormone metabolism.
Vitamin K2 (MK-7)
Directs calcium to bones and away from arteries: essential when taking vitamin D3.
