As we age, or when the body is exposed to stress, pollution, or poor nutrition, glutathione levels tend to decrease
142 A study involving 313 men aged 50 to 75 years found higher DHEA-S levels were associated with lower risk of high blood pressure (averaging 152 mcg/dL in those without hypertension vs
On the surface, it acts as a humectant that holds water in place and reduces moisture loss for a plumper, smoother feel, while its anti-inflammatory and antioxidant properties make it a great pick for calming redness or sensitive skin The more interesting story is underneath: Despite its large molecular size, oat beta-glucan has been shown to penetrate the epidermis and reach the dermis by slipping between skin cells

It is not affected by peptidases in the blood, and is absorbed intact into the cell where the acetyl group is cleaved off producing an intact reduced glutathione
These changes often initiate upwardly spiraling levels of oxidative damage and dysregulation of redox-based cellular communication systems
