Why You Experience Mood Swings During the Menstrual Phase

• Self-compassion: Recognize that low mood is biochemically driven, not personal failure.
• Omega-3 fatty acids: 1-2g EPA/DHA daily supports serotonin receptor function.
• Dark chocolate: Contains tryptophan (serotonin precursor) and magnesium. 1-2 squares is therapeutic.
• Journaling: Writing for 10 minutes reduces rumination and emotional distress.

When to See a Doctor
