Anastrozole / Exemestane (Aromatase Inhibitors) vs Boron
Both are used for joint health. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Anastrozole / Exemestane (Aromatase Inhibitors) | Boron | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★☆☆ |
| Legal status | Prescription, Off-Label | OTC Supplement |
| How it works | Inhibit aromatase (CYP19A1), the enzyme converting testosterone to estradiol. Anastrozole is reversible; exemestane is a suicide (irreversible) inhibitor. | Trace mineral that lowers sex-hormone-binding-globulin (SHBG) — freeing bound testosterone — reduces estradiol via aromatase influence, and improves conversion of vitamin D to its active form. |
| In plain English | High testosterone partly converts to estrogen, which can cause bloating and gyno. These drugs block that conversion. Easy to overdo — crashing estrogen wrecks mood, joints, and libido. | Most of your testosterone is "handcuffed" to a carrier protein and unusable. Boron loosens those handcuffs so more testosterone is actually active. Cheap and underused. |
| Bottom line | Use only if estradiol is genuinely high; low estrogen is as bad as high. | Add 10 mg to a zinc + D3 stack — strong evidence per dollar. |
| Availability | Prescription only | Available over the counter |
