I’ve been taking ZMA every night for the past 5 or 6 days. Last night I woke up in the middle of the night with the worst cramps in my calf. They wouldn’t go away for anything.
Here is my thinking. I have heard that calcium before bedtime can help relieve leg cramps. Magnesium competes with calcium for absorption. Therefore, taking magnesium before bed may result in depleted calcium causing cramps.
Any thoughts/experiences from others?
