Yes, potassium can help ease migraine headaches. Studies have shown that a deficiency in dietary potassium is associated with an increased risk of migraines. Increasing potassium intake may help reduce the frequency and severity of migraines. Potassium works by regulating the body’s electrolyte balance, which helps to stabilize nerve cells and control neurotransmitter activity. This stabilizing effect reduces the occurrence of migraine episodes, as well as reducing their intensity if they do occur. Potassium has been found to reduce inflammation in the brain, which is believed to play a role in migraine headache pain levels.
