L-Cysteine is one of the many naturally occurring amino acids. It is further termed as a protein amino acid. Promoting the stomach lining health is one of the main functions of l-cysteine. It also helps in correction of situations where the essential nutrients from food sources are not being absorbed properly. Generally, most people do not need supplements for obtaining l-cysteine amino acid. It is can easily be found in vegetable, meats and dairy products. Although, l-cysteine is also available in the form of cysteine, which is found in plenty of protein enriched foods. Cysteine is one of those amino acids which are not destroyed by cooking. On the contrary, research shows that cooking of food rich in cysteine may help you absorb them better.

L-Glutathione is a water soluble compound found in living organisms. It is a strong anti-oxidant enzyme that plays a vital role in maintaining health. It also helps in fighting free radical damages that are harmful to health. L-Glutathione is absorbed by the liver. It binds itself to toxins so it can easily be secreted from the body. It also helps in improving the immune system. L-Glutathione has been found to have anti-aging, detoxifying, and anti-carcinogenic properties.

It may also help in managing atherosclerosis, Parkinson’s disease, diabetes, lung disorders, and male infertility.

Selenium is considered good for health if taken in small amounts. It is a trace mineral which when incorporated into protein, makes selenoproteins that helps stop cellular damage due to free radicals. The major source of selenium is plant foods and its content in the food depends on the selenium content in the soil where it was grown. Also known as selenium acid, selenium sulfide and selenium yeast, this mineral is available in seafood and meat products. The main function of selenium is to work with vitamin E in order to maintain the elasticity and preservation of tissues. It not only helps in improving the supply of oxygen and blood to the muscles in the heart but also slows down the aging process by enhancing endurance.

Vitamin A is needed by the retina of the eye in the form of a specific metabolite(the light-absorbing molecule retinal). This molecule is absolutely necessary for both scotopic and color vision. It also palys an important role in the health or our skin, bone metabolism, immune function. It is also commercially produced and administered as esters such as retinyl acetate commonly called Vitamin A acetate. Its defeciency can cause blindness. Other problems include impaired immunity, hypokeratosis (white lumps at hair follicles), keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

Vitamin C is an obvious essential nutrient and a deficiency of this will cause scurvy. It is also an antioxidant and acts as an electron donor for eight different enzymes.

Vitamin E is an antioxidant that is known for protecting the tissues of the body from damage caused by free radicals.

Zinc, a mineral needed for cell division and repair as well as proper functioning of the immune system. Zinc is also an important antioxidant that neutralizes free radicals in the body.
