Efficacy of Withania somnifera supplementation on adult’s cognition and mood

Performed at Jacksonville University

A four week double blind placebo controlled study with a cross over design was performed on 58 healthy adults (men and women) with a mean age of 34 and who have perceived stress. Each group of subjects ingested either 225mg or 400mg of NooGandha® daily or a placebo. This study showed that 30 days of taking NooGandha® (liposomal ashwagandha root and leaf) was safe and well-tolerated and may improve cognitive abilities, cortisol levels, mood, stress, anxiety and food cravings. No adverse events were reported.

225mg or 400mg of NooGandha® taken one time per day for thirty days showed significantly improved benefits in the following:

– Improved cognitive flexibility
– Improved psychomotor speed
– Improved executive functioning
– Decreased cortisol levels
– Improved perceived stress
– Improved visual memory
– Improved reaction time
