Vitamins & Nutritional Supplements for Food Allergy

Probiotics may be important in the control of food allergies because of their ability to improve digestion, by helping the intestinal tract control the absorption of food allergens and/or by changing immune system responses to foods. One group of researchers has reported using probiotics to successfully treat infants with food allergies in two trials: a double-blind trial using Lactobacillus GG bacteria in infant formula, and a preliminary trial giving the same bacteria to nursing mothers. Probiotics may also be important in non-allergy types of food intolerance caused by imbalances in the normal intestinal flora.

Thymomodulin® is a special preparation of the thymus gland of calves. In a double-blind study of allergic children who had successfully completed an elimination diet, 120 mg per day of thymomodulin prevented allergic skin reactions to food and lowered blood levels of antibodies associated with those foods. These results confirmed similar findings in an earlier, controlled trial.

According to one theory, allergies are triggered by partially undigested protein. Proteolytic enzymes may reduce allergy symptoms by further breaking down undigested protein to sizes that are too small to cause allergic reactions. Preliminary human evidence supports this theory. Hydrochloric acid secreted by the stomach also helps the digestion of protein, and preliminary research suggests that some people with allergies may not produce adequate amounts of stomach acid. However, no controlled trials have investigated the use of enzyme supplements to improve digestion as a treatment for food allergies...
