Can you drink coffee before and during your period?
Official recommendations from the American College of Obstetricians and Gynecologists (ACOG) and Association of Reproductive Health Professionals say to avoid caffeine altogether to relieve PMS symptoms and breast tenderness. But people have different sensitivities and reactions to caffeine, and some are more tolerant than others. These recommendations are based on prior studies that could have also been influenced by other factors known to influence PMS, like smoking and obesity.
In fact, in a 2016 study published in the American Journal of Clinical Nutrition, scientists found that after taking these factors into account, high caffeine intake was not linked to breast tenderness, irritability, and fatigue.
But it’s not just PMS that could be affected by caffeine; drinking coffee during your period is linked to longer, heavier periods and other irregularities, according to a 2014 study in the Journal of Taibah University Medical Sciences. Researchers believe this is due to the effect of caffeine on reproductive hormones.
