I received Magnesium Ease by Activation Products in return for my unbiased review. This is a very large 250 ml bottle. It's a spray bottle which makes it easy to apply. This is a topical spray that's applied to the skin. It's used to give a daily dose of magnesium. Magnesium helps with so many issues, from muscle & joint pain, headaches, to better sleep. This spray is easy to use. After showering and drying off, simply apply 20-40 sprays on the skin. Ideal areas for maximum absorption are inside the elbows, behind the knees, wrists, top of your feet, and stomach. Massage into skin after spraying. This spray absorbs quickly and doesn't leave the skin oily. I really like that this spray is a great natural remedy for so many things. I have trouble sleeping and using this spray is much easier than taking pills or supplements. Since using Magnesium Ease, I have noticed an improvement in my sleeping habits. I am sleeping better and wake up well rested. I am happy with the results.
