Glutathione, the body's master antioxidant and detoxifier:

Glutathione is not only a premiere cellular antioxidant, but it is also required for detoxification of many dangerous environmental chemicals. 

In the toxic world in which we now live our liver, detoxification and immune systems are being pushed to the very edge of their capabilities. A quick historical review highlights the fact that since the Second World War an estimated 85,000 synthetic chemicals have been registered in the US alone. Today's environment now exposes us to various pesticides, herbicides, plastics (e.g. PVC), xenoestogens (e.g. bisphenol A, parabens) and pollutants in our food, water and air.
 

Here are some food sources that help boost glutathione levels naturally.

Asparagus is a leading source of glutathione. Foods like broccoli, avocado and spinach are also known to boost glutathione levels as well as Walnuts.  But whenever possible try to eat them uncooked or cooked with as little heat as possible.

Nutritional supplements that help increase cellular Glutathione levels: 

1. N-Acetyl-Cysteine (NAC)
It is derived from the amino acid L-Cysteine, and acts as a precursor of glutathione. NAC is quickly metabolized into glutathione once it enters the body. It has been proven in numerous scientific studies and clinical trials, to boost intracellular production of glutathione, and is approved by the FDA for treatment of accetaminophen overdose.

2. Milk Thistle, Silymarin
Milk thistle is a powerful antioxidant and supports the liver by preventing the depletion of glutathione. Silymarin is the active compound of milk thistle. It is a natural liver detoxifier and protects the liver from many industrial toxins such as carbon tetrachloride, and more common agents like alcohol.

3. Alpha Lipoic Acid
Made naturally in body cells as a by-product of energy release, ALA increases the levels of intra-cellular glutathione, and is a natural antioxidant with free radical scavenging abilities. It has the ability to regenerate oxidized antioxidants like Vitamin C and E and helps to make them more potent. ALA is also known for its ability to enhance glucose uptake and may help prevent the cellular damage accompanying the complications of diabetes. It also has a protective effect in the brain

4. Whey Protein Isolate
Whey protein contains proteins like alpha-lactalbumin which is is rich in sulphur-containing amino acids. Heating or pasteurization destroys the delicate disulphide bonds that give these proteins their bioactivity..

5. Curcumin (Turmeric)
