Ashwagandha, Anti-aging and Cognitive Performance
Article by Arnie GitomerAshwagandha is a traditional Ayurvedic medicine that helps the body maintain metabolic balance. It has been shown to be of value in many areas: Anxiety, Insomnia, Infertility, Sexual Function, Cognitive Performance, Physical Performance and Stamina, Anti-inflammatory and Analgesic Properties, Immune Function, etc.
New studies appear on a regular basis. It seems that “Anti-Aging” can be added to the above listing. One of the primary factors in cell aging is the length of telomeres; the protective end-caps on each strand of DNA. Each time the cell reproduces, telomeres shorten, eventually leading to improper reproduction and cell death.
Telomerase is the naturally occurring protein that slows or stops telomere shortening, an anti-aging effect. In the lab, doctors exposed human cells to ashwagandha root extract and saw a 45 percent increase in telomerase activity.

In addition, another recent study seems to confirm the beneficial action of Ashwagandha on mental function. It significantly improved cognitive performance and reaction times compared to placebo.
(Pingali, Pharmacognosy Res 2014).
In this study, among men and women with mild cognitive impairment (average age of 50) they found that taking 300 mg of ashwagandha root extract twice daily (providing a total daily dose of 600 mg containing 30 mg of withanolides) for 8 weeks significantly improved many aspects of immediate and general memory, executive function, sustained attention, and information processing speed compared to placebo (which showed lesser improvements). Most improvements were not significant relative to placebo after 4 weeks and required 8 weeks. There was no significant effect on visuospatial processing, i.e., drawing images from memory and comparing rotated images.
