Unfortunately, it has been proved beyond doubt that a large percentage of the United States population suffers from nutritional deficiency. Studies show, 30% of the general population has a marginal level of Vitamin C and 15% are Vitamin C deficient. Low level of vitamins and minerals like, calcium, iron, folic acid, magnesium, and chromium continue to be a significant but common problem in the United States. It is also being noticed that children suffering from Autism are the most common patients for vitamin and mineral deficiency. Generally children suffering from Autism have much lower level of vitamins A, C, D, and E, and all B vitamins (except choline) and some minerals (zinc, magnesium, selenium).
