What is L-Cysteine HCl?

L-Cysteine HCl, also known as Cysteine, is a semi-essential, sulfur bearing, amino acid present in protein that is an important component of hair, nails and the keratin of the skin. L-cysteine is considered conditionally essential because it can be made internally in sufficient amounts under normal circumstances, but dietary supplementation may be needed if physical demands on the body (physical exercise, stress, etc.) become too much. L-Cysteine equalizes and sustains protein structure and aids in the formation of collagen, thereby promoting healthy skin, hair and nail texture and elasticity. L-cysteine performs several functions in the body, and it is of great importance in the manufacture of L-taurine and L-glutathione. Taurine is important because it plays an integral role in maintaining healthy central nervous system (CNS) function. Taurine also assists in regulating healthy blood pressure, helps maintain good vision and eye function, and aids in both thermogenesis (fat burning) and muscle building.

Glutathione is of paramount importance for immune system function because it is a potent antioxidant that ensures healthy cellular function and nerve signal efficiency. While direct glutathione supplementation has proven ineffective at increasing cellular glutathione levels (because it gets digested by stomach acids), L-cysteine levels have proven effective for this purpose. L-cysteine supplementation heightens NAC - N-acetyl cysteine (C3H7NO2S). NAC is known to improve blood glutathione levels and preserve lean muscle mass. Therefore, the antioxidative and glutathione raising effects of L-cysteine can be attributed to its ability to increase NAC levels.

L-cysteine is essential for T-cell production and immune system activation. Aside from being a component of human hair, L-cysteine is also a component of the hormone insulin. L-cysteine can likewise be converted into glucose (for energy production) should the need for energy arise when glucose levels in the blood are low. This conversion can provide fuel for athletes, thus enhancing athletic endurance, and prevent muscle catabolism. The gastrointestinal system can also benefit from L-cysteine because by supporting a healthy stomach lining, it can shield the digestive system and stomach from the stress brought by Aspirin, Tylenol and other drugs.

L-Cysteine hydrochloride supplies hydrochloric acid, a naturally occurring stomach acid that helps break up fats and proteins for quicker digestion in the small intestine. Stomach acid also helps make the absorption of nutrients through the walls of the intestines easier so it can go into the blood and delivered where it is needed. Gastric acid also aids in guarding the gastrointestinal tract from harmful bacteria. A normal level of gastric acid in the stomach, which is 100,000-1,000,000 times more acidic than water, is sufficient to kill bacteria, but a low level increases the possibility and severity of some bacterial and parasitic intestinal infections. Cysteine can be manufactured from the amino acid methionine in our body but is also found in high protein foods such as poultry, wheat, broccoli, eggs as well as garlic, onions and red peppers.

What is L-Cysteine HCl used for and who uses it?

Everyone can benefit from L-cysteine supplementation. Physical training can significantly increase oxidative stress, and this may lead to immune suppression. By using L-cysteine, recovery is much faster, and overall health is supported all the way. Its role as a taurine precursor is also helpful in lean muscle tissue gain and thermogenesis. People with compromised immune systems (young children, the elderly and people constantly exposed to pollutants) can really benefit from dietary supplementation of L-cysteine due to its immuno-protective and antioxidative effects. L-cysteine can strengthen immune system function and maintain optimal health. Cysteine is needed by our skin as well as to detoxify our body. It is available in beta-keratin, the main protein in nails, skin as well as hair. Aside from playing a key role in collagen production, Cysteine also assists in skin elasticity and texture. Cysteine is also required in the manufacture of the amino acid taurine and is a component of the antioxidant glutathione. It is beneficial in detoxifying and clearing the body of harmful toxins, and protecting the brain and liver from damage from alcohol, drugs etc.

Cysteine works closely with glutathione to eliminate toxins from the liver. In fact, cysteine is used a lot in emergency rooms to immediately treat and alleviate acetaminophen overdoses, which are known to cause liver damage. It also shields the liver and brain from the harmful effects of toxins coming from alcohol and cigarette use, and can be effective in preventing hangovers, as well as preventing liver and brain damage. Because it triggers the production of the powerful antioxidant glutathione, cysteine supplementation may be useful to those suffering from conditions that have been linked to free-radical oxidative damage, such as hardening of the arteries and cancer. It may also help treat emphysema, tuberculosis, and bronchitis, as cysteine has been demonstrated helpful in breaking down mucus in the respiratory tract. By itself Cysteine is a powerful free radical destroyer, but it works best in the presence of vitamin E and selenium because they work synergistically. It also detoxifies and protects the body from radiation damage, so it is often used in chemotherapy and radiation cancer treatments.

It has also been shown that it may help in reinforcing the protective lining of the stomach as well as intestines, to prevent damage and irritation caused by aspirin and similar drugs. Cysteine is also crucial to metabolize essential biochemicals such as coenzyme A, heparin, biotin, lipoid acid, and glutathione. Additionally, Cysteine is required for proper vitamin B6 utilization and is also helpful in the healing of burns and wounds, breaking down mucus deposits in illnesses such as bronchitis as well as cystic fibrosis. Cysteine also has an anti-aging effect on the body by reducing age-spots etc. and this is made possible by its action of increasing the level of glutathione in the lungs, liver, kidneys and bone marrow.

How pure is your L-Cysteine HCl?

This pharmaceutical grade amino acid L-Cysteine Hydrochloride is assayed by the manufacturer to be 99.75% product (normal range 98.5% and up). You will receive a sealed and labeled heavy duty 4 mil polyethylene bag containing this white powder product. It contains no fillers, taste additives, or anti-caking agents. The remaining 0.25% by weight are inactive byproducts of the extraction.

This pure bulk L-Cysteine HCL powder is a sulfur containing nonessential amino acid used by the body to build proteins. Because of its high affinity for binding metals and other toxins, Cysteine is frequently taken in combination with Vitamin C to detoxify, chelate, and remove harmful metals and free radicals from the body. For these reasons, it makes sense to consider taking it as a supplement.

What is the daily suggested dose of L-Cysteine HCl?

There is no Recommended Dietary Allowance (RDA) for cysteine primarily because it can be manufactured within the body, and can also be obtained through high protein foods, such as meat and eggs. Wheat, broccoli, garlic, onions and red peppers are also good natural sources of cysteine. The typically recommended dose for L-Cysteine HCL generally varies between 600 milligrams to as much as 2 or 3 grams per day in two or three divided doses, depending upon individual needs. One fourth level teaspoon will supply approximately 898 milligrams, or almost 1 gram for the bulk density of this L-Cysteine HCl powder. You can see the full bulk density/volumetric conversion chart for L-Cysteine HCl here.

As always, if you have concerns or questions, consult a physician or a health care professional before taking any supplements. Before taking any kind of medicine, check with your doctor to ensure that the supplement you want to take is right for you. You may be allergic or you may have a sensitive stomach which may raise the need for special instruction as far as dosage goes.

Precautions and Potential side effects of L-Cysteine HCl

People suffering from AIDS/HIV may benefit from cysteine in proper amounts, as low levels are normally reported in people with this problem, but people suffering from diabetes should be careful when taking supplementation, as it could inactivate insulin. Optimal doses of L-cysteine supplementation may produce beneficial effect, but high dosages of L-cysteine are linked to oxidative stress and possible DNA damage. Because of this, always consult with a physician prior to use. Persons with cystinuria should avoid using l-cysteine as they can form cysteine gallstones from its use. Be sure to drink enough water as well when supplementing with L-cysteine.
