Your liver is the organ that picks up breakdown products of your own metabolism and removes them from your body. The promoters of liver-detoxifying supplements tell you that their products "support healthy liver function" and help it do its job better.
CAT scans of the body are high-speed, highly sensitive X-rays that can find tiny tumors, weak spots on blood vessels that make them bulge out like balloons, and calcified areas that may be indicative of heart disease.
We do not know how safe sunscreens are because they have never been tested systematically. Oxybenzone in sunscreens has been shown to be absorbed into the bloodstream in humans, and to disrupt hormones in animals. Zinc oxide and titanium dioxide appear to be safe, except that manufacturers often convert them to nanoparticles that can be inhaled.
