A simple method to get magnesium will be to add green leafy vegetable like collard greens or kale to your smoothies. Alternatively, you could take a scoop of Vega One Nutritional Shake that has around 30 percent of your daily recommended dosage. Adding Epsom salts in bath is also a good way. It has high amounts of magnesium, which is readily absorbed from the skin while you are relaxing in the tub.
