Aspartame Myths: Headaches

A carefully controlled study was done at Duke University Medical Center with people who were convinced that aspartame caused their headaches. This study, which was published in the New England Journal of Medicine, demonstrated that aspartame does not cause headaches or migraines.

Headaches are one of the most common human complaints. Many factors can cause headaches, ranging from stress and sleep disturbances to physical illnesses. It is potentially dangerous to assume that a headache is related to aspartame, when the cause may be a serious physical or psychological condition.
