Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.

Cures Constipation

Posted by Reviewer3126738 on Nov 28, 2007

"Combination forms" of magnesium such as this one have cured chronic constipation I've had for over 40 years, since childhood! I take one a day and that keeps me regular better than anything else I've tried over the years. It has made my stools soft and easy to pass, with no feeling of urgency. I began with 500 mg from another brand with great results, then had to reduce the dosage because my stools were getting too loose. Now I am needing to adjust the dosage again, so with continued use, you will need less for the same great results!Adjust the dose and frequency according to your body's needs and you may be happily surprised with the results too. The capsules are easier to swallow than tablets, and I have found that only the combination forms of magnesium such as NOW and Life Extension brands work this great for me, better than oxide or citrate alone.

We, 4 people, tried it and it's really bad!

Posted by MichaelLabib on Aug 19, 2012

I have always liked NOW Foods products, actually I have like 12 open bottles from this brand. But I have to say that this product is worthless, it had no effect whatsoever. I know a good quality Magnesium supplement product, when my heart rate drops and when I'm relaxed. This product had no effect at all, if you are looking for a great Mag supplement try UltraMag from Source Naturals. It's an honest review, and it's not just mine. We are 4 people living at the same house, and we all agreed on this review.

Three excellent forms of magnesiums in one capsule!!

Posted by LivingNatural on Oct 20, 2012

This Now Foods magnesium contains 3 different forms of mangesium, which are excellent. For example Magnesium Citrate has high absorption and Magnesium Aspartate boosts natural testosterone levels! Overall magnesium is one of most important minerals. I'm usually taking 1-2 capsules with water before going to sleep and always removing gelating for better absorption. It helps me recovering from hard training and protects the nervous system.

Low back pain has vanished!

My daughter suggested the addition of magnesium to balance the calcium I was taking. I am now totally without low back pain. Thank you iHerb!!! Edie

very effective

Posted by Reviewer1760262 on Dec 22, 2008

These are great for relaxing my chronic tight muscles (back and neck) and tension head-aches. I take two pills, twice daily. They start working in about 30 minutes, and all is well again...
