Phosphatidyl Choline 420mg 180sg by Designs for Health helps protect the liver against damage from alcohol, pollution, toxins, prescription and over the counter medication, mushroom poisoning, and radiation. Phosphatidyl choline (PC) is one of the most important nutrients to consume daily for optimal health. PC is found in nuts, seeds, dandelion greens, and egg yolks: foods we consume too little of to get an optimal intake of PC. Most adults do not get enough of this valuable nutrient. An inadequate intake of PC can lead to poor liver function, fatty liver, gallstone formation, premenstrual syndrome, fibroid tumors, fibrocystic breast disease, and other hormonal disorders in women, poor memory, and nerve degeneration.
