What It Measures
The blood concentration of estradiol, the most potent form of estrogen.
Estradiol is the primary estrogen in men, produced via aromatization of testosterone. It is essential for bone health, brain function, and cardiovascular protection — but excess can cause issues.
Current Value
What High Means
Elevated estradiol in men (often from aromatization due to excess body fat) can cause gynecomastia, water retention, mood changes, and may suppress LH/testosterone production.
Possible Symptoms
Water retention, breast tenderness, gynecomastia, mood swings
What Low Means
Low estradiol in men increases risk of osteoporosis, joint pain, cognitive decline, and cardiovascular issues. Estrogen is protective even in men.
Possible Symptoms
Joint pain, fatigue, low libido, bone density loss
Risk Factors
Gynecomastia (high), osteoporosis (low), cardiovascular risk (low)
Actionable Advice
Supplements
- •DIM (diindolylmethane, if high)
- •Calcium D-glucarate
- •Zinc
Diet & Lifestyle
- •Reduce body fat (fat tissue aromatizes testosterone to estrogen)
- •Cruciferous vegetables support estrogen metabolism
- •Limit alcohol (increases aromatization)
- •Avoid xenoestrogens (plastics, BPA)
