L-cysteine is a basic building block of the the antioxidant glutathione, the human body's most important antioxidant. Glutathione recharges vitamins C and E as they are used as antioxidants. It helps protect DNA from chemical damage. It detoxifies heavy metals, and it helps keep arteries and airways open. It also activates many important functions of the immune system.
L-cysteine is also the amino acid every cell uses to make inteins, the enzymes that "snip" protein molecules to the right size and configuration, and the caspases, which dissolve dead cells, especially dead cancer cells, from the inside out.
How The Body Acquires L-Cysteine
L-cysteine is not an "essential" amino acid. Under optimal conditions, the human body can manufacturer it from the amino acids serine and methionine. If the folic acid, vitamin B6, and vitamin B12 are not available, however, the body cannot make the enzymes that complete the conversion of serine and methionine into L-cysteine.
Once the body has made L-cysteine from serine and methionine or digested it from food or supplements, it uses L-cysteine along with two more amino acids, glutamine and glycine, to make the "master antioxidant" glutathione. There are some foods that contain glutathione, and it is possible to find a glutathione supplement, but so little of the antioxidant survives the digestion process that the body has to make essentially all of its own glutathione. Cysteine is usually the amino acid in shortest supply for making this antioxidant.
L-Cysteine for Allergies
L-cysteine supplements can be very helpful for allergies that cause snot and phlegm. It doesn't stop the production of mucus, but by breaking down the bonds that cause the collagen in mucus to clump, it can make nose and throat secretions runnier and easier to expectorate or sneeze away.
L-Cysteine for Skin Protection
L-cysteine helps the skin defend itself against sun damage. Together with selenium, vitamin C, and vitamin E, L-cysteine helps skin cells form the enzymes that keep a gene called p53 active. This "watchdog" gene triggers a series of steps that cause a potentially cancerous cell to undergo a process called apoptosis, or "cell suicide." When p53 detects changes in skin DNA that could cause cancer, it shuts down the cell. L-cysteine is also important for the formation of the caspases that dissolve the cell once it dies.
L-cysteine for acne
L-cysteine is also frequently recommended for acne, with the explanation that it "helps vitamin B5 work better." Vitamin B5 is pantothenic acid, often marketed in skin care products as Panthene or Panthetine. Typically the Internet experts who recommend a combination of L-cysteine and high-dose vitamin B5 for acne argue that since vitamin B5 is water soluble and any excess is quickly removed from the bloodstream by the kidneys, the only way to trick the kidneys is by taking a mega-dose of vitamin B5 to work with the L-cysteine.
Please understand that l-cysteine is helpful in some cases of acne, but not in others. L-cysteine will help when:
- Benzoyl peroxide treatment of pimples causes acne inflammation of its own. A combination of l-cysteine and alpha-lipoic acid reduces redness and itchiness of pimples in this case. Vitamin E creams and supplements, by the way, actually make the inflammation worse.
- Women who have polycystic ovarian syndrome develop acne as a symptom. L-cysteine helps cells in the skin become more sensitive to estrogen and less sensitive to testosterone (which is produced in excess when women have polycystic ovarian syndrome). Taking an L-cysteine supplement may be very helpful for women who also take the medication Clomid (clomiphene). Results will be less noticeable in women who are not on medication for hormone imbalances.
Vitamin B5 for Acne Treatment
Most of the time, L-cysteine won't help acne. And what about the vitamin B5/Panthetine recommendations? Actually, if you take a lot of vitamin B5 capsules, your body can't absorb biotin. If you create a biotin
deficiency by taking high-dose vitamin B5, your skin's oil production will increase, not decrease. The result will be a different kind of bump, known as seborrheic dermatitis, but you won't be helping your acne, either.
Vitamin B5 or panthothenic acid skin creams, on the other hand, can be very helpful. Since they are applied directly to the skin, they don't keep the body from absorbing biotin. The skin uses pantothenic acid to make coenzyme A, which releases energy from carbohydrates, fats, and proteins. A clinical study in China of 45 males and 55 females between 12 and 30 years of age found that applying a cream made with pantothenic acid began to eliminate pimples in 1–2 weeks. The cream contained 10 grams of pantothenic acid diluted to a 20 percent concentration. It was applied 4–6 times per day. The physicians supervising the study noted no side effects.
Take l-cysteine capsules. Use pantothenic acid creams.
What About L-Cysteine for Hair Care?
L-cysteine used to be made by dissolving human hair. Human hair is about 14% L-cysteine. Nowadays this amino acid is extracted from duck feathers. Since L-cysteine used to be made from hair, many people have supposed that taking L-cysteine supplements would be good for the health of hair.
The problem with taking lots of L-cysteine for hair growth is the same as with taking lots of L-cysteine for skin growth. When you take large amounts of L-cysteine, your digestive tract can't absorb as much biotin. And when there is biotin deficiency sebum production increases and in the worst cases can literally choke the hair follicle so that hair falls out.
What about an L-cysteine shampoo? Here the problem is that visible hair is not living. It has already been created, and it cannot incorporate L-cysteine into its structure. And unless you leave the shampoo on your scalp 24 hours a day, the L-cysteine is not going to seep into the follicle that produces the hair, which uses glycine and tyrosine in greater amounts than L-cysteine, anyway.
The best way to support hair growth is by making sure you consume balanced amounts of protein every day. L-cysteine is not the only amino acid in the proteins that make up hair, and you can't get into inside the hair shaft by rubbing it in your hair.
What Are Legitimate Uses for L-Cysteine?
- You suffer congestion caused by allergies.
- You deal with chronic bronchitis or emphysema.
- You have acne that is made worse by benzoyl peroxide or you are a woman who has acne related to polycystic ovarian syndrome (PCOS).
- You have sun-damaged skin and you are concerned about future development of skin cancer.

ACTIVE INGREDIENTS
YEAST EXTRACT
Yeast extract is the common name fro various forms of processed yeast products that are used as food additives or flavorings. Yeast is recommeded as source of Vitamin B12.
L-CYSTEINE
L-Cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-Cysteine) and L-Methionine from which L-Cysteine can be produced in the body by a multi-step process. Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a metyhl donor in the conversion of homocysteine to methionine. Cysteine also helps systhesize glutathione, one of the body’d most important natural detoxifiers. N-acetyl-cysteine is the acetylated form of L-cysteine, which is more efficiently absorbed and used.
APPLE POLYPHENOLS
Polyphenols extracted from apples are also showing promise in treating male pattern baldness, improving skin disorders and preventing allergic reactions. Apple polyphenol extracts have been shown to be 2 to 6 times more powerful then Vitamin C as antioxidants. Apple polyphenols are naturakky occuring plant compounds that act as potent antioxidants. They protect cells against free radicals, reactiveatoms that contribute totissue damagein the body.
Recently, apple polyphenol extracts have been announced to dramatically decrease organ fat and increase musclestrngth in laboratory animals.
GRAPE SEED EXTRACT
Grape seed extract is a natural plant substance that has a concentrated source of oligomric proanthocyanidins (OPC). These anti-oxidants help protect cells from free radical damage and also promotes healthy circulation. Grape Seed Extract is rich in polypheols, a compound that’s high in antioxidants. Studies have shown OPC to be more powerful antioxidants than Vitamin C, E and beta-carotene.
Health Benefits of Grape Seed Extract:
· One of the most powerful antioxidants that fights free radicals
· 20 Times more potent than Vitamin C and 50 times stronger than Vitamin E
· Helps improve cardiovascular health
· Helps promote brain, skin and eye health
· Anti-bacterial, anti-viral and anti-inflammatory
· One of the few antioxidants tthan can penetrate the blodd brain brrier to help protect the brain and nerve tissue
· Prevents the formation of plaque in the arteries
· Improves mental alertness and help prevent senility
ASTAXANTHIN
Astaxanthin is a natural extract of dried Haematococcus pluvialis microalgae, rich in the red carotenoid pigment astaxanthin. A growing body of scientific literature is demonstrating that dietary astaxanthin has profound antioxidant potential and beneficial effects on health.
Haematococcus has never been associated with any toxicity in the reported literature or in field of studies and numerous animal and human studies lend support to its safety (Maher 2000).
LACTOSE
Lactose (also referred to as milk sugar) is a sugar that is found most notably in milk. Lactose makes up around 2-8% of milk (by weight), although the amount varies among species and individuals. It is extracted from sweet or sour whey. The name comes from lacte, the Latin word for milk, plus the –ose ending used to name sugars.
