Glutathione is a small protein composed of three amino acids: cysteine, glutamic acid, and glycine. It is involved in detoxification and antioxidant mechanisms. Many toxins are dealt with by "handcuffing" the toxin to another molecule so it can be escorted out of the body. The process of adding one molecule to another is called conjugation.

Glutathione is one of the most important conjugating compounds, which helps the body eliminate fat-soluble toxins, such as heavy metals, solvents, and pesticides, transforming them into a water-soluble form to allow more efficient excretion via the kidneys. The combination of detoxification and free radical protection results in glutathione being one of the most important anticancer and anti-aging agents in our cells. Dietary glutathione intake is associated with protection against some forms of cancer.

Some of them are backed by solid research, others are folk remedies or proprietary cures. If your diet does not include enough of certain vitamins or minerals, a supplement may be a good idea. Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
