Certain protein types help the liver break down and clear toxins: Numerous studies link low-protein diets with a higher toxic load. (To avoid fat-soluble environmental toxins, be sure to choose vegetable-based protein—tofu, nuts, beans, quinoa—or small amounts of organically raised lean meats.) Whey protein is particularly helpful in that it also boosts glutathione levels. Dose: Blend 21 grams of high-quality whey protein powder into a smoothie daily.

It’s a good idea to talk to your health care provider before starting a new supplement.
