What is Glutathione

Just what is Glutathione?

Glutathione is an important small tripeptide molecule in our body that is famous for its anti-aging power. It’s also known as the “master antioxidant”, as it helps recycle and maximize the function of other antioxidants, such as vitamin C, vitamin E, coenzyme Q10 and alpha-lipoic acid. It is made up of the following amino acids:

  1. L-cysteine
  2. glutamic acid
  3. glycine,

The human body produces glutathione, naturally all the time. The various parts of the body, especially the lung, intestinal and liver have glutathione. Liver use glutathione to eliminate toxins and excreted through the bile. The liver also provide glutathione for red blood cells and leukocytes directly so that the immune system can maximize disease resistance.

Normally glutathione is recycled in the body, except when the toxins becomes plenty.

What is L-Glutathione

The commercial glutathione products available today contain reduced glutathione (L-Glutathione), since this is the active form. This doesn’t mean that it has less glutathione.

Reduction is a process where oxygen is lost and hydrogen and electrons are gained, so reduced glutathione is missing an oxygen molecule but has an extra donor electron!  Basically the GSH molecule needs to be in a reduced state so that it is available to neutralize free radicals by bonding it’s extra electron to the reactive oxygen species molecules ‘dangling’ free radical electron..

Glutathione Uses

Every cell in the body takes such raw materials to prepare glutathione. Each cell’s glutathione have many functions, including the three most important functions of

  • anti-oxidant
  • enhance immune function and
  • detoxification.


Free radicals may contribute to aging and some diseases. Antioxidants help to counteract free radicals and protect the body from their damaging effects.

As an antioxidant, glutathione removes oxygen radicals from the body which can harm other cells in the body and cause disease and deterioration.

Glutathione is a very strong antioxidant, partly because high concentrations can be found in every cell in the body.

Enhance immune function

Glutathione will also be a beneficial compound for those who suffer from a compromised immune system or an immunodeficiency. A well-functioning immune system is highly dependent on optimal levels of glutathione.

Glutathione helps in a process called cloning. During an infection, the immune system must produce a lot of white blood cells to fight  the invading bacteria or virus. The body’s immune response is directly related to the number of white blood cells the body can produce.

Thus, the body’s requirement for glutathione increases substantially when the immune system is challenged. If gsh levels are low, your immune system won’t be effective.


Glutathione is responsible for regulating several detoxification functions. For example, “gluta” is required to detoxify toxic metals like mercury and lead, pesticides, herbicides, fungicides, nitrates, cigarette smoke, plastics, and many different kinds of drugs.

Since the liver is the primary organ of detoxification, glutathione levels are highest in liver tissue. Glutathione depletion rapidly leads to liver damage.
