Full Description

Osumex L-Cysteine

Produced in Japan from microbial fermentation with no animal origin and
are Halal and Kosher certified. It is different from and superior to
N-Acetyl-L-Cysteine (NAC-L-Cysteine). NAC-L-Cysteine, generally sold as
a dietary supplement as an antidote for acetaminophen overdose, is a
derivative of Cysteine. Most other L-Cysteine is produced industrially
by hydrolysis of animal materials such as poultry feathers or hog hair.

Pre-cursor to the antioxidant glutathione

Due to the ability of thiols to undergo redox (reduction-oxidation)
reactions, cysteine has antioxidant properties. Its antioxidant
properties are typically expressed in the tripeptide glutathione, which
occurs in humans and other organisms. The availability of oral
glutathione is negligible, so it must be biosynthesized from its
constituent amino acids, cysteine, glycine and glutamic acid. Cysteine
is an important source of sulfide in human metabolism. The sulfide in
iron-sulfur clusters and in nitrogenase (enzymes responsible for the
reduction of nitrogen which is a key step to the process of nitrogen
fixation required for all forms of life) is extracted from cysteine and
converted to alanine in the process.


Cysteine is often used in food, pharmaceutical and personal care
industries with the largest application being in the production of
flavours. For example the reaction of cysteine with sugars in a Maillard
reaction yields meat flavours. L-Cysteine is also used as a processing
aid for baking. Cysteine is also used in hair for permanent-wave
applications, predominantly in Asia. It is also a very popular target
for site-directed labeling experiments to investigate biomolecular
structure and dynamics. Other uses include being a preventive or
antidote for the negative effects arising from excessive alcohol
consumption including liver damage and hangover. It counteracts the
poisonous effects of acetaldehyde turning it into acetic acid.

Dietary Sources

Many foods rich in protein usually contain L-Cysteine but in small
amounts. Meat and soy products are the best source to use to provide
sufficient intake of the minimum daily amounts of 1,400 mg. Vegetarians
can get their supply from sunflower seeds and walnuts. Soybeans have the
highest concentration with approximately 655 mg per 100 gm. L-Cysteine
is soluble in water and when cooking care must be taken to avoid keeping
them in water too long so that the amino acid is not washed out.


Glutathione is produced naturally by the liver and also found in fruits,
vegetables and meats. It is a compound synthesized from cysteine. Like
cysteine, glutathione contains the crucial thiol (-SH) group that makes
it an effective antioxidant. It is a combination of three simple
building blocks of protein or amino acids cysteine, glycine and
gluthamine. Glutathione is called the master antioxidant because it can
regenerate itself in the liver. Glutathione is involved in many
processes in the body, including tissue building and repair, making
chemicals and proteins needed in the body, for the immune system. It is
the master detoxifier and the bodys main antioxidant protecting our
cells and making our energy metabolism run well. Certain foods contain
precursors to help the liver produce more glutathione. They include
sulfur-rich foods such as garlic, onions and cruciferous vegetables
(broccoli, kale, collards, cabbage, cauliflower, watercress), premium
bioactive whey products and colostrums. Others are Vitamin C, milk
thistle and turmeric. Exercise also boosts glutathione levels which in
turn boost your immune system, improving detoxification and enhance the
bodys own antioxidant defenses.

The benefits of using L-Cysteine and Glutathione

Skin and Hair L-Cysteine and Glutathione play an important role in
protein synthesis and is a natural building block of many important
structural proteins in connective tissues.

Male Fertility researches have found that cysteine lowered the
concentration of damaging reactive oxygen species within semen. Semen
volume, viscosity and mobility are significant better. Glutathione
enhances the the function of citrulline as part of the nitric oxide
cycle. Nitric oxide improves blood circulation and lowers blood pressure.

Inflammation L-Cysteine and Glutathione help reduce inflammation of
reproductive tissues and organs which can in turn support fertility and
in the therapy of osteoporosis especially in older women.

Immune system L-Cysteine supports the production of Glutathione which
inhibits inflammation leading to an overall strengthening of the immune
system. They are important in the metabolism of lipids and enables the
production of cell membranes and protective covers of nerves. They are
also essential for maintaining healthy mitochondria as damaged or
malfunctioning mitochondria are part of the cancer process. Glutathione
has a vital function n iron metabolism. Glutathione levels regulate
redox changes to nuclear proteins necessary for th initiation of cell
differentiation where a less specialized cell becomes a more
specialized one.

Anti-ageing L-Cysteine support the synthesis of glutathione which is a
powerful antioxidant. Glutathione plays an important role in
detoxification resulting in the protection of tissues and organs. Raised
glutathione levels decrease muscle damage, increase strength and
endurance and shift metabolism from fat production to muscle
development. They are critical in helping the bodys first line of
defense against infections, disease and illness.

Other benefits effective in treating fatty liver disease for both
alcoholics and non-alcoholics. The sulfur chemical groups help to
capture damaging free radicals and heavy metals for elimination from the
body. Glutathione is one of the major endogenous antioxidants produced
by the cells , participating directly in the neutralisation of free
radicals and reactive oxygen compounds. It is highly beneficial to
smokers in this way.
