The intestinal flora communicates directly with the body's hormonal system and can influence the production and metabolism of several important hormones, such as:
-
Estrogen, which is important for women's fertility
-
Insulin, which affects blood sugar levels and may be linked to PCOS
-
Stress hormones such as cortisol, which affect hormone balance and menstrual cycles
Probiotics can reduce low-grade inflammation, which can disrupt hormone signals. By improving the absorption of vitamins and minerals necessary for hormone production, probiotics can contribute to a more stable hormonal balance. Research at Örebro University shows important interactions between the gut and the brain that can affect hormones: Brain-gut interactions after probiotic supplementation .
