Many cancer patients have complaints of fatigue and brain fog due to the lingering effects of chemotherapy. In almost every case we find that these patients have low glutathione. Glutathione is the bodies master antioxidant and primary detoxifier 

Long-term deficiency of glutathione may be responsible for the build-up of carcinogens in the body.

Raising glutathione levels will help the body clear residual chemotherapy agents. Glutathione is poorly absorbed orally and is destroyed by the GI track unless specially formulated to withstand the stomach acids. Recancostat is a specially formulated form of highly absorbable glutathione designed specifically for cancer patients.

Glutathione's pre-cursor, N Acetyl-Cysteine, commonly known as NAC, (pronounced knack) is most commonly used as it is easily absorbed and is converted into glutathione in the body. Many forms of NAC also have minerals and vitamins included which aide in this conversion.

Any of the products listed below will help raise glutathione levels. Recancostat comes in 400mg and 100mg sizes. I recommend starting with the 400mg size until your symptoms clear and then use NAC or the lower dose Recancostat for maintenance.
