Magnesium Powder is a convenient effervescent drink mix that provides a highly-absorbable, quick-acting source of magnesium. It mixes easily in water and helps the body maintain healthy levels of magnesium. The blend of citric acid and magnesium carbonate creates a special ionic form of magnesium. Ionic magnesium, when added to water, produces the characteristic carbonation or fizzing experience. Fizzing is an indication that a chemical reaction is taking place, and this reaction renders the magnesium completely soluble in water. Magnesium Powder is a highly-absorbable, quick-acting magnesium supplement that helps the body respond quickly to stress, and helps give the body a deep sense of relaxation.
