Ashwagandha is the trendy, if hard to pronounce, supplement that's taking social media by storm. An evergreen shrub native to India and the Middle East, ashwagandha may be having a moment, but it's been used for thousands of years in some medical practices. While more research is still needed, studies are starting to suggest that the plant's thousand-year reign as a medicinal herb might be grounded in some clinically-verifiable health benefits.

"Ashwagandha is classified as an 'adaptogen,' meaning it is believed to help the body manage and adapt to stress," Dr. Soma Mandal, a board-certified internist at Summit Health in New Providence, NJ, told CBS Sports Essentials.

"It is also used for a variety of conditions including anxiety, arthritis, insomnia, and chronic liver disease, among others. Some people also use it to enhance their thinking ability, decrease inflammation, and improve their overall health."

Keep reading for a deeper dive into the health benefits of ashwagandha that have the most clinical research backing them. Then, get our recommendations for some of the best ashwagandha supplements if you want to try them for yourself.

Important note: Ashwagandha, especially in the high doses found in many supplements, can interact with certain medications and isn't recommended for people with certain health conditions. Make sure to talk to your doctor before taking ashwagandha.

What are the benefits of ashwagandha?

Some of ashwagandha's most-studied health benefits include its ability to reduce stress, improve sleep, boost cognitive function and strengthen muscles.

Ashwagandha may decrease your stress and anxiety

One of the most well-known benefits of ashwagandha is its calming effects. "Several studies suggest that ashwagandha may help reduce stress and anxiety," Dr. Mandal said. "It's believed to do this by blocking the stress pathway in the brain by regulating chemical signaling in the nervous system."

In multiple clinical trials, patients taking a supplement made from ashwagandha root or a blend of the roots and leaves had reduced cortisol (a stress hormone) levels after six to eight weeks along with decreased symptoms of stress. Doses in these trials ranged from 225 mg to 600 mg per day.

Ashwagandha may improve your sleep

In addition to its calming effects, ashwagandha is also sometimes used as a sleep aid. According to Dr. Mandal, "The leaves of the ashwagandha plant contain the compound triethylene glycol, which has been found to improve sleep."

In a 2021 meta review of five clinical trials, researchers found that taking 600 mg or more of ashwagandha per day improved sleep quality and quantity in adult subjects. On average, subjects fell asleep faster and got more total sleep through the night than those who were given a placebo.

Ashwagandha may improve your memory and cognitive function

The herbal supplement has also shown some benefits to overall cognitive function, especially memory and focus.

At least three randomized clinical trials found that ashwagandha improved memory, executive function, attention and information processing speed. Doses ranged from 500 mg up to 1,000 mg per day for up to eight weeks.

One possible reason for that, according to Dr. Mandal, is ashwagandha's antioxidant properties.

"Ashwagandha has been shown to promote antioxidant activity that protects nerve cells from harmful free radicals. Studies have suggested that it may help improve memory and cognitive function," said Dr. Mandal.

Ashwagandha may increase strength and muscle mass

A handful of studies have looked at the potential for ashwagandha to improve athletic performance, with some showing an improvement in muscle strength and size as well as improved VO2 max (how much oxygen your muscles can use during vigorous exercise).

The best ashwagandha supplements in 2024

Now that you've learned about the potential benefits of the herb, it's time to shop for the best ashwagandha supplements you can buy in 2024.

Best ashwagandha supplement overall: Toniiq Ashwagandha+


Toniiq Ashwagandha+ is a potent supplement boasting 1,300 mg of ashwagandha leaf and root extract per serving. The third-party tested supplement is highly concentrated, with each serving containing a minimum of 25% withanolides, the compound in ashwagandha most strongly linked to its many health benefits.

While many supplements only contain root extract, this ashwagandha supplement stands out for its blend of leaf and root extracts. The science is still inconclusive on whether there's a significant difference in health benefits between the different parts of the plant. But if there are, this blend covers all the bases.

We also like that each serving is split into two capsules. So if you want to take a smaller dose, you can simply take one capsule per day rather than two to cut your dose to 650 mg rather than 1,300 mg.
