If you have trouble sleeping, taking magnesium oil can help to ensure you get a good night’s sleep. It’s just one of the benefits of this important mineral, although many of us still don’t regularly get enough of it. Other magnesium oil uses include taking a supplement to alleviate muscle pain and to help build stronger bones and teeth. A variety of skin problems and conditions can be treated by taking a magnesium supplement, including psoriasis, acne and eczema. The oil can even be used as a surprisingly effective deodorant, preferably when lavender or another essential oil is added. It’s also beneficial when it comes to a healthy heart, as a magnesium deficiency has been linked to heart problems and high blood pressure. And anyone with diabetes should take a magnesium supplement regularly as it can help to maintain appropriate insulin levels.
