SULFUR-CONTAINING AMINO ACIDS
These include the amino acids methionine, homocysteine and cysteine. Often, authorities also include taurine in this group of chemicals, although it is technically not an amino acid.
These are among the most important of the amino acids. Their main purpose is to help with the flexibility of connective tissue, and they are also absolutely essential for detoxification in the liver and elsewhere.
Glutathione synthesis requires them. For example, cysteine can be the rate-limiting step in the production of glutathione. Glutathione is an important molecule for liver detoxification. We do not supplement it because it is not necessary and it is too yin. Instead, we suggest eating a lot of onions and other foods that contain the sulfur-containing amino acids.
Authorities also say that mercury irreversibly binds to sulfyhdryl groups, which involve cysteine.
Sources. The sulfur-containing amino acids are found naturally in a wide range of foods. Among the most important are meats, eggs, some well-cooked beans and some seeds such as sesame.
The onion family - garlic, onions, scallions, green onions – are high in these chemicals, as well.
Other vegetables that are rich in sulfur are the cabbage family (cabbage, cauliflower, broccoli, and Brussels sprouts), and the radish family of vegetables. However, these are not quite as rich in sulfur as onions, scallions and garlic, along with the meats and eggs. The sulfur is usually more abundant and in a more usable form in animal foods.
Isolated supplements. Foods are best, so I rarely recommend isolated amino acids. Reasons to beware of isolated amino acids include: they are all very yin, which is not good. Also, it can be hard to figure out which to supplement, and they must be kept in balance. Also, they are costly.
Most important, they are not needed, in most cases, if one takes a powerful digestive aid such as GB-3 and eats animal protein daily to supply all of them, plus many other nutrients. Also, too many pills seems to confuse the body, at times.
Amino acid powders and protein powders must be taken with water and often sweeteners that are terrible food combinations and upset the digestion badly.
Sulfur-containing amino acids are sold as isolated supplements include L-taurine, N-acetyl-cysteine, methionine, cysteine, glutathione, MSM or methylsulfonyl methane, alpha-lipoic acid and others. Some herbs also contain them such as bugleweed, yellow dock and some others. They tend to have a yellowish color, as this is the color of sulfur.
These amino acids may also be a part of chelation drugs (EDTA, DMPS and others) and other chelating substances such as chlorella and cilantro.
All are chelators. Sulfur-containing amino acids are very mild chelators. This means they can bind with metals in the body such as copper, lead and a few others. It also means you must exercise caution with them, as they may remove some vital minerals along with the toxic ones.
SULFUR AMINO ACIDS IN NUTRITIONAL BALANCING PROGRAMS
Taurine for four lows pattern. L-Taurine is the only sulfur-containing amino acid used regularly in nutritional balancing programs, and this is only when a four lows pattern is present. I am not sure why, but L-taurine works excellently in this situation. To learn more, please read the article entitled, Taurine on this website.
