What should I know about was ist ostrogen?

Estrogen is a primary female sex hormone crucial for menstrual cycle regulation, bone density, and cardiovascular health. MyBody-X tests do not measure hormone levels in blood; they analyze genetic markers related to nutrition and metabolism. Genetic predisposition may offer hints about hormone metabolism but cannot replace clinical hormone testing. For symptoms like cycle irregularities or menopausal issues, a doctor and blood test are required. The evidence for DNA tests in hormone optimization is weak and mostly marketing-based.
