Magnesium is a vital mineral that plays a crucial role in over 300 biochemical reactions in the body, yet many people are unaware they are deficient. This deficiency can lead to a range of issues, from trouble sleeping to muscle cramps and fatigue. One effective way to boost your magnesium levels is by applying magnesium oil to your feet every night. This simple ritual can have significant health benefits, especially when it comes to improving sleep and relaxation.
