Meta-study: vitamin D supplementation boosts muscle strength

Vitamin D not only plays a key role in maintaining bone strength, it also plays an important role in muscle growth. Because almost everyone suffers from a vitamin D deficiency, you'd expect that average people would gain strength if they took extra vitamin D. British sports scientists analysed data from 6 previously published studies and concluded that vitamin D supplementation does indeed boost muscle strength.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
