L-Glutathione, provided by Douglas Laboratories,
supplies 250 mg of L-Glutathione in its reduced active form in a gelatin
capsule. Body cells and tissues are threatened continuously
by damage caused by toxic free radicals and reactive oxygen species (e.g.,
peroxides) which are produced during normal oxygen metabolism, by other chemical
reactions, and by toxic agents in the environment. Free radicals are capable of
disrupting metabolic activity and cell structure. When this occurs, additional
free radicals are produced which, in turn, can result in more extensive damage
to cells and tissues. The uncontrolled production of free radicals is thought to
be a major contributing factor to many degenerative processes seen during aging.
Glutathione is a naturally-occurring tripeptide of Lcysteine, L-glutamate and L-glycine.
Glutathione is the essential cosubstrate for two major antioxidant enzymes in
the body; glutathione peroxidase and glutathione reductase. As such, glutathione
offers one mechanism for scavenging toxic free radicals. L-Glutathione may be a useful dietary supplement
for individuals wishing to increase their intake of glutathione. Adults take 1 capsule daily or as directed by
physician. No adverse side effects reported. Store in a cool, dry place, away from direct
light. Keep out of reach of children. Best TM, Fiebig R, Corr DT, et al. Free radical activity,
