Research published in the New England Journal of Medicine shows that an enzyme found in red blood cells, called glutathione peroxidase 1, could predict the risk of heart problems in people suspected of having coronary artery disease (Blankenberg S, et.al., 2003).
Researchers followed 636 patients for nearly five years and found that those with higher levels of this enzyme were less likely to experience heart-related events.
On the other hand, another enzyme, superoxide dismutase, showed no such link. Interestingly, the enzyme's levels were influenced by factors like gender and smoking but remained a reliable predictor. The study suggests that, besides traditional risk factors like cholesterol levels, monitoring this enzyme could provide additional insight into heart health.
Glutathione is a powerful antioxidant the body makes, but we are making less as we get older. By supplementing with S-Acetyl Glutathione, we can increase glutathione levels in the cells which help to protect us from free radical damage.
