🧬 How Supplements Reduce Hot Flashes (Explained Simply)
Hot flashes occur when declining estrogen causes the brain’s thermostat (the hypothalamus) to become over-sensitive. Supplements help by:
- Supporting serotonin & temperature regulation
- Reducing inflammation

This is why combinations often work best.
