The best Magnesium on the market
This magnesium supplement is the best I have ever used. My personal trainer recommended it to me and I would purchase through her company. But when she sold out, she provided me with the link she uses and now I order directly. I’ve been using this product for about a year now and it is a MUST have product for me as it helps give me energy and speeds up my metabolism. Food digests better and I just think my whole body works better. I ran out and was off of them for about two months, because I always got them from my trainer and had no idea I could get them through Amazon until she gave the link. I gained 5 lbs during this time. I take two capsules daily and have zero side effects. Amazing product!

Great product highly recommended!!!
I love this product and been taking it for almost a year now. It truly work wonders – I sleep a lot better (took care of my insomnia) and wake up feeling good with mental clarity, took care of my constipation problem. I’m 67 y.o female sort of feeling exhausted all the time and this product gave me daily dose of energy I needed. Satisfied customer here. This was recommended to me by a friend of which in turn I have recommended to other friends as well. It’s truly a great find!

3 in Magnesium
This 3 in 1 Magnesium supplement seems to be an excellent product. I wish there was a way for a household consumer to know exactly how high quality a supplement truly is. My guess is this is a good supplement and taking it has increased my deep and REM sleep.

This might be the best product for you, but it is not for me…..
Really helps with sleeping at night. However would get really vivid dreams and would wake me up with something sudden like falling out of a window, etc. Also would hurt my bladder by take 3 pills all at once. I cut it down to 2 and then 1 a night. Pain would be better, but still waking up in pain. This might be the best product for you, but it is not for me.

Best Magnesium we’ve tried.
This is the best magnesium supplement we have tried. At first I was the only one in my family taking it at night, but now we are all using it to help with sleep and muscle health.
