Hi Brans,
Moducare is an excellent product. I discuss the benefits of immunomodulators like Moducare in my book on Graves' disease. There are many products out with similar benefits so you might want to compare products and ingredients to price. Most contain plant sterols and sterolins.
Quercetin and bromelain are recommended by Dr. Andrew Weil to help slow down the allergic response. I''ve been taking them for years. Bromelain is also a good digestive enzyme and both of these nutrients help reduce inflammation. They're very good supplements for most everyone. Another excellent supplement in this family is alpha-lipoic acid. Studies show that L-carnitine and alpha lipoic acid increase energy and mental function in older patients. Best, Elaine
