That is why The Foundation began to produce pharmaceutical grade supplements, and has access to a state of the art laboratory where trained chemists conduct innovative assays on its products. The Foundation has gained such a solid reputation for its quality control standards that in April of 1999 it was asked to analyze seven different brands of SAMe by a national news magazine. To ensure quality and inform consumers, a Quality Control Assay Report is available to members on any supplement upon request. In reviewing The Foundation s suggested supplement program, namely Life Extension Mix, Life Extension Booster and Chronoforte, I became concerned about the total amount of selenium in the combined package. For the moment, the latter issue has kept me from taking the Booster and Chronoforte.
Selenium is an essential cofactor of glutathione peroxidase and is an important antioxidant.
It is involved with iodine metabolism, pancreatic function, DNA repair, immunity and detoxification of heavy metals. The most recent studies demonstrate that selenium improves cardiac function and significantly improves cardiac functional recovery and decreases postischemic myocardial injury. For the average person, this study indicates that around 1000mcg of selenium a day is safe. Therefore, the combined amount of 500 mcg of selenium should pose no problem for you. I am writing an educational monograph on CLA and I ran into a problem that I can't figure out.
