Surveys over recent years suggest that as much as 40% of the U.S. population may be deficient in magnesium. Magnesium plays roles in the cardiovascular and GI systems, energy production, and the heart, brain, kidney and liver.* For instance, magnesium is involved in the body’s homeostatic maintenance heart rhythm.* Magnesium contributes to bone formation and mineralization, and it plays a role in the regulation of muscle and nerve activity through influencing cell membrane permeability.* Since 1979, ijk has used only the purest raw materials available, and has implemented strict quality control procedures in every stage of production, including inspection of raw materials, manufacturing, packaging, and storing. ijk fully discloses all ingredients, both active and inactive, on every product label, so consumers can make fully informed choices for their nutritional support. We define hypoallergenic as “free of all common allergens”, specifically, wheat, corn, soy, gluten,dairy, eggs, fish, crustacean shellfish, tree nuts, and peanuts. Many very sensitive individuals who react to supplements in general are able to tolerate ijk products. Originating with the ground-breaking oxidant/antioxidant work of Stephen Levine, Ph.D., we were one of the first to introduce truly hypoallergenic products to the market.Since 1979: ijk has been using only the purest raw materials, with strict quality control. Free of wheat and gluten, dairy, eggs, soy, fish, shellfish, peanuts, tree nuts. Suggested Use: Take 1 capsule one to three times daily between meals, or as directed. Supports healthy nervous system, stress response, and healthy sleep*. Magnesium is a macromineral considered essential for over 300 biological processes in the body*.
