Magnesium is an essential mineral for most processes of the body. It is difficult to absorb through the diet, and is best absorbed via the skin when used in a bath. Revitalizing for as little as 20 minutes in the bath (or even a foot soak!) can help us face the next challenges life throws our way, and transition to a calmer, more peaceful state of mind. EpZEN magnesium bath crystals are of the highest pure quality of laboratory tested magnesium sulphate that we could find anywhere, having undergone a delicate filtration process ensuring no perceptible impurities and safe for external use. Just as important when bathing is keeping the vulnerable pH level of our skin's acid mantle intact - easily disrupted by everyday soaps and detergents yet crucial to guarding you against environmental elements, pollutants, and ageing free-radical. EpZEN pH is in the absolutely optimal range to maintain skin integrity - measuring from 5 to 7 (varying whether bathing in hard, soft, or neutral eg.rain water). RELAX: beautifully scented with pure natural essential oils of Rosewood, Ylang Ylang, Rose Geranium, Frankincense, and May Chang. Wonderful for the overworked, overburdened, or stressed out - and anyone else! Use 2 cups in a bathtub, or 1 cup in a foot soak bucket. As a precautionary measure, AVOID if pregnant. Great for stress and pms.
