Research from PLOS ONE found that nearly 50% of those who menstruate in the US crave chocolate at the start of their period. But why, exactly? Let’s dive into the science behind this popular period craving.
Hello, Hormones
During your menstrual cycle, your hormone levels fluctuate. In particular, serotonin and dopamine, two neurotransmitters responsible for mood and pleasure, take center stage. As your body gears up for menstruation, serotonin levels can drop, leaving you feeling a bit down in the dumps. Cue chocolate, which contains compounds that can temporarily boost serotonin levels and elevate your mood.
Magnesium
Chocolate, specifically cocoa, is very high in magnesium, which many menstruators usually run low on when they’re in the premenstrual phase of their cycle. It’s like your body’s instinctive way of saying, “Hey, I need a little boost here!”

Emotional Comfort
Let’s face it — Premenstrual Syndrome (PMS) is REAL. PMS can bring mood swings, irritability, stress and even depression for some. Beyond its chemical properties, chocolate is a form of comfort to many menstruators. Whether you prefer dark, milk, or even white chocolate, it offers a moment of indulgence and self-care in the midst of the hormonal changes happening during your cycle.
