Comex is good, remember that it is American Comex, and there are fakes. If you buy a fake online, you must buy it at the largest local shopping mall or drugstore. My family has been taking American Comex products for 10 years. At first, it was brought back from abroad by relatives on business trip, and the effect was very good. The doctor said that middle-aged and elderly people had better eat fish oil and lecithin together. I have been eating his protein powder and natural vitamin E from Hainan Yangshengtang, which is good. Anyway, Comex and Amway in America are the best health food.
