Chicory
Hess looked at a potential treatment for patients with impaired management for minerals through the use of omeprazole. In a mouse study he showed that the dietary fiber inuline, which is found in chicory, lowers the acidity in the intestines, which allows magnesium to be better absorbed. He also studied the effect of inuline on ten patients with a magnesium deficiency. They took inuline with food. It took 14 days of taking inuline for the concentration of magnesium in the blood to recover, during this time the patients continued taking antacids. The patients reported fewer incidents of fatigue and muscle cramps. In the future, inuline will be tested on larger groups, "The patients who participated in the study are still taking the dietary fiber inuline."
