Let’s think about this for a moment. When you look at the back of a box of cold cereal it says you get 100% of so many nutrients. Tell me one person who has optimal health eating only cold cereal. No one does. But we go to the health food store and buy the same synthetic nutrition and expect it to make us healthy. Oral magnesium decreases the uptake of nutrients your body can uptake from food. Oral magnesium also cannot get you to cell saturation and that is where magnesium really starts doing the work of keeping you healthy. Oral magnesium is also usually mixed with citric acid which is made from black mold and hard on the gut lining.
