Good product

Got this for a great price. I’ve no problems taking pills, but I can see some people think they are large. They are definitely not small. The pills are like a soft gel. I take one before bed each night. I’ve not noticed any after taste or “pill burps”. I would buy them again.

This Product Works Better Than Any I Have Tried

I take a medication called Dofetelide. This medication takes the Magnesium out of your system and if it gets too low then the medicine stops working. Since I was told to start taking Magnesium I have always had good results taking Nature Made Magnesium 400 mg.

Magnesium

I heard magnesium helps with sleep and decided to try a supplement to see if it works. When I took during the morning I didn’t see a difference in my sleep but when I too it in the evening I was shocked when I had slept for 7 hours straight!

Great supplement for my body

This is a great supplement to my daily intake of vitamins and minerals to stay healthy. This also helps me relax before going to bed to get a better night's sleep.

Great supplement for leg cramps!

I used to have leg cramps at night on a regular basis after playing basketball or riding a bike. After I started taking Magnesium(at a friend's recommendation), now I rarely suffer from leg cramps. I highly recommend you give it a try.

Awful smell

I have used magnesium for years. When I opened this bottle the smell was awful. It smelled like wet dirty diapers. I returned the bottle today at Sams Club.

Don't sell just Extra Strengh medicenes.

You should be selling the regular strength tablets in addition to this one. My wife reacted badly to this one and it can't be cut in half because it is a jell. Thus, we have to throw away safely 149 pills.
