Anastrozole / Exemestane (Aromatase Inhibitors) vs Glycine
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) | Glycine | |
|---|---|---|
| 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. | Smallest amino acid; inhibitory neurotransmitter at spinal/brainstem glycine receptors (GLRA1), lowers core body temperature (a sleep-onset trigger) via peripheral vasodilation, and supplies one-third of collagen's amino acids. Mimics some… |
| 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. | An amino acid that gently cools you down and quiets the nervous system for sleep, and is the main brick in collagen. Dirt cheap, very safe. |
| Bottom line | Use only if estradiol is genuinely high; low estrogen is as bad as high. | One of the most undervalued supplements — sleep + connective tissue + longevity. |
| Availability | Prescription only | Available over the counter |
