Dietary Supplement Magtein Dr. Mercola has been providing quality products since 2001. As you grow older, your body becomes less efficient and effective in absorbing important vitamins and minerals. So, despite a healthy diet rich in fresh organic vegetables, you may still come up short in certain nutrients. One such mineral that might need extra help with is magnesium. And that's why I created Magnesium L-Threonate. So what makes my Magnesium L-Threonate supplement so special? Magnesium L-Threonate… Completely avoids magnesium stearate – Magnesium stearate is not a healthy source of magnesium to help boost your supply. Delivers a high-absorption formula – Magnesium L-Threonate was selected over other forms of magnesium due to its excellent absorption characteristics. Incorporates high-penetration characteristics – Animal studies have shown how Magnesium L-Threonate uniquely crosses the blood-brain barrier and penetrates cell membranes. Takes advantage of high-tech encapsulation and delivery system – The Licaps encapsulation/delivery system provides superb leakage protection. Helps manage potential discomfort – Many forms of magnesium can cause unpleasant gastrointestinal discomfort. Magnesium L-Threonate is not a stool-softener and does not act as a laxative. Provides practical, easy-to-take servings – By taking 1g after lunch (or in the afternoon) and 1g at bedtime with plenty of water, it's quick and convenient to take. Is delivered by a reputable high-quality manufacturer – With its commitment to product innovation, the chosen manufacturer has been a trusted source for core functional ingredients since 1996. Plus, Magnesium L-Threonate is free from any genetically engineered (GE) ingredients. With all the options you have available in a magnesium supplement, I truly believe this is one of your best choices available.
