Reduced Leg Cramps Review by

My husband started to get nasty, regular leg cramps at night. I got him Nutra-Life Magnesium Complete and he's not had any since. Recommended.

Amazing Review by

I have never been a good sleeper and with going through the menopause was waking every 2 hours for months. Did try taking a sleep product that was magnesium based but it had the opposite effect. Started taking this Magnesium Complete product quite by accident as got is as a free gift when ordering something else and it is truly amazing. I now only ever wake once a night, if that, and have no trouble going to or back to sleep. I take it in the morning with breakfast too and it still works and no problems with digestive system. I thank God I was sent this as a free gift and will take it for life.

Sounder deeper sleep Review by

My sleep is much improved from taking this product. No more leg cramps. Still wake at night but have little trouble getting off to sleep again. I take it with glass of raw milk last thing at night because magnesium and calcium work well together.

Improved sleep Review by

I take a magnesium complete tablet once a day and find it has given me an energy boost as well as assisting with better sleep.

Great but quite strong Review by

I went through a period when my body was trying to fight something off so I would get cramps at night. I started taking these instead of the weaker ones and they stopped they cramps. I have now gone back to the weaker once because I don't think I need to have ones this strong all of the time

Restless Legs! Review by

I have found this product very helpful for muscle relaxation and have less problems with restless leg syndrome at night.

Magnesium complete Review by

I usually take Thompsons magnesium but decided to try this as it was on special. I haven't had leg cramps since using magnesium. The Nutra-Life tablets are very large so might be hard for some to swallow.

Awesome product Review by

Used to have agonizing cramp in the night at times, so I found this in my Mums medicine cupboard and it fixed it. I just took one before bed the next night and I had no problem for about a week!
I got a bottle for myself, and every-time I have cramp it works like a charm!! Also gave one to my husband the other day to help him sleep better and it worked as well for that...Would recommend it to anyone.

It's great Review by

I like this magnesium as I'm sure it helps with sleeping and haven't had any side effects.
