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

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.
