Glutathione supplements are products used to supply the body with additional glutathione. This protein molecule consists of amino acids, cysteine, which is a nonessential amino acid, and glycine, which is the simplest of the amino acids that make up proteins. The body makes its own glutathione, and it is present in every cell. It is also found in a variety of foods. Some people use it as a supplement because it of its antioxidant effects, which may make it helpful for both fighting and preventing disease.
Many are interested in glutathione supplements because of the protein molecule’s antioxidant activity. Some research studies have produced evidence that the molecule may provide protection from or help to treat a wide range of diseases and conditions, proving especially helpful in treating conditions that are linked with aging. For example, this substance may prove helpful for fighting cancer, cataracts, and high blood pressure. It has even been named as a possible treatment for male infertility.
There is some question as to whether or not taking glutathione supplements by mouth provides much health benefit. Some research shows that oral supplementation may not provide for optimal absorption. Instead, some studies suggest that absorption may be more efficient when the protein is taken through a vein.
Since taking glutathione intravenously isn’t a likely choice for most people, some researchers believe using precursors is a better option. Essentially, this involves supplementing with substances that help the body to produce glutathione rather than taking glutathione supplements. More studies may be needed, however, before researchers are sure whether this is the optimal solution for those seeking to increase their glutathione.
Generally, taking glutathione supplements is thought to be safe for most people. Those who have allergies to milk protein and individuals who have had organ transplants may be advised to avoid it, however. Additionally, some scientists have speculated that glutathione may encourage cancer growth in individuals who have precancerous cells. The idea behind this concern is that the same qualities that help glutathione to encourage the health of normal body tissues may also work to protect the health of cancerous tissues. This is not proven, however.
Like many types of health-protective substances, glutathione is found in a range of food sources. This, combined with the fact that the body produces it, means a person doesn’t necessarily have to take glutathione supplements to experience its effects. If a person consumes a well-balanced diet, he may get enough of the protein without supplementation. For example, a person who eats plenty of fruits and vegetables as well as meals prepared from fresh meats may get enough from diet alone.
