No one seems to know what causes leg cramps and I have used every vitamin, mineral etc. and have had some relief until lately. Now that I'm on the melatonin I seem to be experiencing them frequently (nightly).
Hi my me is Terra and my 2 teens take melatonin 10mg to sleep during the school days and they've never experienced cramps. They've been taking them for over a or. It sounds like your potassium may be low, you should get your levels checked because it's not the melatonins.
I take 3mg (time release) of melatonin every night and sleep great, but wake up with severe leg cramps every morning. Severe meaning I can't walk for an hour and need to stretch, hot tub and down 2 advils before I can start my day. The cramps get less during the day, but don't stop. This has been going on for 3 months and I have tried many solutions. No joy. After seeing your post, I am going to try taking no melatonin, and taking a magnesium instead. I'll try this for a few nights and see if there is any change. Will report back if there is an improvement.
After having some really severe leg cramps I was looking around on the internet and came across these responses. Only other med I take is lisinopril blood pressure pills and occasionally heart burn pills but not days or weeks on end.
About two days after I stopped taking the melatonin they all but went away - a week and running and not even getting the foot cramps I was before. I had been taking them pretty regularly 5mg for about a year and a half and had been having some of the leg cramps. Still not entirely sure it's all related but it sure is weird everything stopped within 48 hours of stopping.
I've been searching for an answer for why I'm getting severe leg cramps. I can't even walk some days and the only thing I haven't stopped taking is melatonin. I'm going to try this. I hope it works.
I take melatonin occassionally and have taken it twice this week and had severe cramps in my feet. This wasn't your typical charlie horse and had to jump out of bed several times to work it out. This past summer I had them so bad I thought I was going to pass out from the pain. I took a magnesium pill and it help? I eat bananas every day so I know I'm not low in magnesium. I also had my levels tested and they were good. I also exercise regularly and drink water. Just seems to coincidental that they came back when I took the melatonin.
I've taken Melatonin off and on, usually just when I can't get to sleep. Pretty much use it as a sleeping pill. I've used various brands, some with supplements like Valerian Root. I never tied my leg cramps and the Melatonin together before until recently. Seems that every time I take the Melatonin lately I wake up with leg cramps. I take a daily multiple plus Calcium, Magnesium, Potassium, and a B12 complex, so I'm sure it's not a lack of something. I'm voting for the Melatonin causing them and maybe find an alternative to my insomnia.
