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.
