Ashwagandha Root Extract Uses

We take a look at the common supplement ingredient Ashwagandha. 

What Is Ashwagandha?

Ashwagandha root extract comes from an evergreen shrub that is native to Asia and Africa, most commonly used for stress related disorders there's a reasonable amount of evidence to support it's use[1] when tested against placebo groups with anxiety disorders. 

The extract is being studied for a multitude of other uses, including as a testosterone booster, sleep quality and pretty much everything from rheumatoid arthritis through to immune system and cognitive impairment. 

Ashwagandha does have quite a few health benefits, although some of the above listed are more hype than substance.

Ashwagandha For Testosterone

There are a lot of studies testing ashwagandha root extract in placebo controlled studies for its testosterone boosting effects, whilst even a couple of years ago it may not have seemed all too effective. However, with more research being done into traditional medicine it is starting to show that it's perhaps more effective than originally thought.

With double blind placebo controlled trials showing an 18% increase in testosterone levels[2] amongst participants. 

Typically speaking ashwagandha makes it into most of the products on our best testosterone boosters list.

Ashwagandha For Stress

Ashwagandha has been shown to reduce anxiety symptoms and stress as mentioned in the introductory paragraph. In terms of reducing chronic stress ashwagandha root extract has also shown to be effective in small sample studies[3]. It has also been shown to have some assistance in maintaining healthy sleep quality[4], which could explain it's effectiveness for stress as well as some of the testosterone level improvements.

Overall there is strong evidence to suggest it is effective at reducing anxiety, stress and improving sleep quality.

Ashwagandha For Insomnia

Ashwagandha is perhaps most well backed for it’s use in treating insomnia [5] having been shown in multiple trials to improve sleep quality and reduce insomnia symptoms in a good percentage of participants. It also has some studies that suggest it could potentially reduce anxiety, which could relate to improved sleep quality, however more evidence is needed to clear Ashwagandha extract for such uses.   

Other Uses For Ashwagandha

There has been some evidence to support Ashwagandha for chronic fatigue syndrome and due to its mild anti inflammatory properties for rheumatoid arthritis, although there is less research that currently supports this.

Ashwagandha may also lower blood pressure, this should be considered before combining Ashwagandha usage with other supplements or medications.
