Just a warning to those of you that don't know much about Magnesium oil, be careful where you buy it from. Make sure you know where they are sourcing there magnesium from. Many sources can be potentially dangerous to your health. Some may contain pollutants or even heavy metals. The brand I like and trust most is Magnesoothe and they source theirs from the Dead Sea. They have a sterling reputation for a clean and effective product. Whoever you get your magnesium oil from, just make sure that they are completely open about where there get it from, how they get it, is there any chemicals involved in the process, how they handle it, how do they filter out the magnesium sulfate, amonia, and mercury that is naturally found in any sea/ocean water, and how often do they inspect their final product.
