I am a healthy 76-year old woman. I eat well, and exercise a lot. I hydrate. I get leg cramps at night that are very painful. I am thinking maybe I should be taking calcium-magnesium-potassium. What amount would you recommend?

Hello and thank you for submitting your question!

Leg cramps can occur for many different reasons that may or may not be nutritionally related. I encourage you to consult with your doctor or a qualified health care professional to help explain what may be causing your leg cramps before taking dietary supplements. Many dietary supplements contain ingredients that are potentially harmful.1 Your doctor or health care professional can discuss whether taking this supplement is safe and appropriate for your needs.
