Healthy aging. How can we slow down and delay the aging process? Certainly, nutrition is one factor in anti-aging. Specifically, adequate intakes of the micronutrient selenium may prevent disease and may enhance healthy aging. Inadequate intakes of selenium, on the other hand, may result in diminished immune function and may accelerate the aging process [Bjorklund 2022].

Professor Alehagen lectures about selenium and aging — **Professor Urban Alehagen was the lead researcher on the KiSel-10 study of the effect of combined selenium and CoQ10 supplementation on cardiovascular health in elderly citizen low in both substances.**

To a considerable extent, aging is associated with the oxidative damage caused by harmful free radicals to cells and DNA and proteins. Selenium through the work of antioxidant selenoproteins, e.g., the glutathione peroxidases and the thioredoxin reductases, improves our bodies’ antioxidant defenses against free radical damage [Bjorklund 2022; Avery & Hoffmann 2018]. read more
