Ashwagandha: What It Is, What It Brings and How to Choose a Supplement
Withania somnifera · Also known as Indian ginseng, winter cherry
Ashwagandha has moved from Ayurvedic pharmacy to the global stress-and-sleep aisle in barely a decade. This restorative root is now one of the most popular adaptogens for calm days, restful nights and everyday vitality.
What is ashwagandha?
Ashwagandha is the root of Withania somnifera, a shrub of the nightshade family native to India and parts of Africa and the Middle East. Its characteristic compounds are the withanolides.
Most commercial products use a root extract standardised to a stated withanolide percentage, which gives each capsule a consistent daily amount.
Traditional and regional use
Ashwagandha is central to Ayurvedic practice as a rasayana or restorative. The plant itself also grows in dry regions of Africa, and today it reaches the region as a supplement ingredient in stress, sleep and vitality formulas.
What is ashwagandha known for?
Good to know. Supplements containing ashwagandha are food supplements, so their labels describe support for everyday wellbeing.
Randomised trials have examined ashwagandha for everyday stress, sleep quality, and measures of strength and endurance, and several report benefits.
Reviews describe the research as encouraging, with the best results reported for standardised root extracts.
How is it used in supplements?
Ashwagandha is used in stress, sleep, men’s vitality and general adaptogen products. Common trial doses fall roughly between 250 mg and 600 mg of standardised root extract per day.
