Why aromatase matters
Aromatase converts testosterone into estradiol. Excess visceral fat raises aromatase activity — which is why fat loss is the most powerful 'natural aromatase inhibitor' you can deploy.
What has evidence
Zinc sufficiency, body-fat reduction, moderate boron supplementation, and reducing alcohol have the strongest natural-AI evidence in men.
What does not
Chrysin: poor oral bioavailability. Grape seed extract and resveratrol: in vitro promise, weak human data.
Frequently asked questions
- Is body fat really the biggest factor?
- Yes. Aromatase is concentrated in adipose tissue. Lose 10 pounds of visceral fat and watch free T climb.
- Can natural AIs replace medication?
- For men with clinically high E2, no. For mild elevations alongside lifestyle work, sometimes.
