It is estimated that as many as 75 percent of Americans don't get enough magnesium from their daily diet, which is why more and more nutritionists are recommending magnesium supplements to their clients—but not all magnesium supplements are the same. Some have better bioavailability than others and some can cause stomach discomfort in some people. Swanson Ultra Albion Chelated Magnesium Glycinate powder utilizes TRAACS technology to bring you a highly bioavailable magnesium supplement that's gentle on the GI tract. Just one scoop of this flavor-free powder delivers 400 mg of magnesium.
