🧪 Boron: Steroid Hormones (Testosterone, Estrogen) and Calcium Metabolism
How boron affects hormones, bones and mineral metabolism
Boron is a trace element that affects steroid hormones and calcium metabolism. Let's look at how it supports testosterone, estrogen and bone health.
What is boron
Boron is a trace element involved in steroid hormone, calcium and magnesium metabolism. It affects hormonal balance, bones and the brain.
- Trace element for hormones.
- Affects calcium metabolism.
- Supports bones.
- Affects the brain.
Effect on testosterone
Boron can raise free testosterone and lower sex hormone-binding globulin (SHBG). This matters for muscle mass, libido and energy.
- Raises free testosterone.
- Lowers SHBG.
- Supports muscle mass.
- Important for libido.
Effect on estrogen
Boron affects estrogen metabolism, especially in menopausal women. Studies show higher estradiol with boron intake.
- Affects estradiol.
- Useful in menopause.
- Supports hormonal balance.
- Important for women and men.
Calcium and bones
Boron improves calcium and magnesium absorption, supporting bone mineral density. This matters for osteoporosis prevention.
- Improves calcium absorption.
- Supports magnesium.
- Strengthens bones.
- Osteoporosis prevention.
