What can we do to reduce oxidative stress as we get older?

We know that aging is associated with oxidative stress.  This research tested whether glutathione deficiency occurs because of diminished synthesis and contributes to oxidative stress and what could be done about it (Sekhar RV, et.al., 2011).

Two groups that were divided into age groups made up the participants.  Both older and younger participants were infused with glycine and measured for red blood cell (RBC) glutathione synthesis and concentrations, plasma oxidative stress, and markers of oxidative damage.

Compared with the younger participants, the elderly participants had markedly lower RBC concentrations of glycine, cysteine and glutathione synthesis and higher oxidative stress.

After infusion with glycine, glutathione synthesis increased significantly and oxidative stress decreased significantly. No difference was found between the older and the younger participants after the infusion.                                                                  

The researcher stated that glutathione deficiency in elderly humans occurs because of a marked reduction in synthesis.

Does this mean that you have to go and have infusions all the time?

No, it’s not that complicated anymore.  You can supplement with S-Acetyl Glutathione, which is a very effective form of glutathione and gets it into the cells where it’s needed (Cacciatore I, et.al., 2010).   Don’t make the mistake and supplement with reduced glutathione–which is the most common form on the market. No significant changes were observed in biomarkers of oxidative stress, including glutathione status of oral glutathione supplementation (Allen J, Bradley RD, 2011).
