Arrived on time. I began taking these nightly 2 months ago because I would get horrible migraines every morning. Since I have been taking the magnesium I have not had a single migraine. I am definitely sticking with magnesium and the brand is great as well.

Beware trying to swallow these horse pills! I've bought this brand of Magnesium pills from the store before and the tablets were a lot smaller. The dosage was twice as many as this bottle, though. Looks like these are either the new formulation or an older one... I think I like the smaller ones better just because they're easier to take, but this is still a great brand. The forms of magnesium in this bottle are some of the best for absorption.

The magnesium contained within Source Naturals Ultra-Mag is of very high quality. Magnesium glycinate is the most bio-available form and ideal for human consumption as opposed to some of the junk forms of magnesium such as oxide (which is poorly absorbed by the blood.)

So far the supplement has done its job and I've felt noticeable relaxing effects because of it. Taking this before bed is a fantastic sleeping aid.

The only reason I give this three stars is because of the 50 mg of B-6. Long term excessive use of supplemental B-6 can be toxic and cause serious neurodegenerative problems. Headaches, fatigue, nerve damage, and loss of motor control can occur with B6 toxicity. The tolerable upper limit set by the FDA is 100 mg a day, but not everyone agrees on that and New Zealand rules 50 mg a day as the upper limit and the UK says 25 mg. The truth seems to be that we really don't know what safe supplemental levels of B6 are and either way 50 mg daily is dangerously close.

So essentially I would recommend Source Naturals for recovering from magnesium deficiency, but as for long term use it just doesn't seem entirely safe.

Do your research and know what's in your supplements.

after a few weeks of experiencing horribly painful muscle cramps in my calves upon waking/stretching, i did some research and found i may be in need of a magnesium supplement. Source naturals has been a staple in my cabinet for years, so i headed here to amazon just like you and went for a highly reviewed product. Never had a cramp since my first order arrived. Good thing too, nothing like starting the day waking up and getting a pain in your calves akin to a rapid wolverine trying to eat your leg.

My husband had been found to be low in magnesium after having lab work done, so I bought this Ultra-Mag for him. He was impressed with the increased energy it gave him both day and night. ;-) It is the magnesium of choice for us now.

I take two pills at bed time to help me fall asleep.
It helps relax and calm my mind down.
I do get vivid dreams sometime. I like this.
Most people are magnesium deficient btw.

Update:

Several Months later and I'm not sure this is really working well. Looking into other magnesium supplements.
