- Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization.
- It is a required cofactor for an estimated 300 enzymes.
- Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism.
- Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.*

Take one capsule late in the evening and it will relax you enough to have a peaceful night. A warning; it can make you go to the toilet in the morning (no. 2), so if you are a late sleeper and you feel your stomach rumbling, don't ignore it and let one off.

As most people probably know, if you want to have a strong bones you need to have magnesium in your diet - as it is necessary to for transporting calcium to your bones (obviously it also has many other benefits, but for me, this was the main one).
I've been using those for the past few months and they are quite good. The only "issue" that I have is that the dosage (as one capsule) is probably slightly on the high side (however, since it was my personal choice to go for 400mg capsules, it shouldn't be seen as a negative part of the review). It would be probably better to split that dosage into two different capsules, as a high dosage of magnesium in one go can cause diarrhoea (I think in my case, 400mg is "on the border" of that dosage - anything more, like 500-600mg would probably be too much). I would suggest starting with something like 100-200mg, just to test your body response and increase the dosage later, according to your needs.
The other point to remember is that low and high protein intake inhibit magnesium absorption, and because of that, it's probably better to take it on an empty stomach at night or just before going to bed -> which is exactly what I've been doing (obviously there is no point of taking it after a large, protein-rich, meal).
In overall: a good product with a fast delivery time

great supplement
11 Jan 2011
Size Name:180 Caps|Amazon Verified Purchase
It is believed that magnesium is responsible for assisting your body in processing calcium and keeping it in the bones, whereas phosphorus (and phosphoric acid) leach the calcium from the bones, causing bone spurs [joint pain], kidney stones, weak bones (osteoporosis). Magnesium is also supposed to help lower blood pressure.
I can say I have taken this supplement for years and never suffered a kidney stone and I noticed that when I first started taking this supplement a lot of my joint pain went away (and stayed away). I also have great bone density.
The NOW Brand seems to be one of the, if not the best supplement companies. I hope they continue to produce the same quality they have in the past. It gets frustrating when companies cut quality to save money.

I started supplementing with magnesium capsules to help with a benign (non-life threatening) irregular heartbeat. This product continues to keep things in check, so it is effective. This is a great value price as I won't have buy more for several months. I love NOW products - Great product at a great price!
