Caffeine Restriction Probably Won’t Help Your PMS After All

A lot of medical advice isn’t based on sound science. One example is the common suggestion that women with premenstrual syndrome (PMS) cut back on caffeine.

From AJCN:

“Our findings suggest that caffeine intake is not associated with PMS, and that current recommendations for women to reduce caffeine intake may not help prevent the development of PMS.”
