Good quality

Whenever I took it, my lower jaw pain is gone. Not sure why but maybe magnesium helps to calm the nerves

Really effective

This is the only magnesium supplement I've ever taken that I can feel a physical effect shortly after taking. I now take it during the day instead of before sleep

Okay

This magnesium is not for me. There are many types of magnesium. This one made me have loose stool. I am looking for one to work with vitamin D to strengthen my bone

Mag3

More effective than most single-component magnesium. Since using this, all our magnesium deficiency symptoms have disappeared.

Easy to swallow capsules

Good size that is easy to swallow and don't get stuck in your throat like the coated type. I take at night to help with sleep and haven't had any problem with loose stools.

very helpful in promoting good sleep

I have been pleasantly surprised at how helpful this supplement has been in helping me sleep. The only caution I would mention is that it has made potassium levels in blood test a point or so abnormal.

Good magnesium for those with thyroid problems

This magnesium has the same ingredients that are in one that’s made by a well known thyroid brand for a much better price. It works great for sleep and relaxation but is also supposed to help with belly fat related to cortisol and hypo thyroid:
