4/5 Deeper sleep

“Magnesium -- I started taking it for the muscle cramps after long runs and it turned out to help with general sleep quality too, which I wasn't expecting.”

2/5 Morning grogginessSide effects

“Some people do report feeling more rested with slightly less sleep after starting magnesium, but I'd be careful not to assume magnesium is directly “reducing sleep need.” It may be helping sleep quality for you, or there may be other factors involved.”
