The 9 Best Ashwagandha Supplements in 2022

Byrdie / Chloe Jeong

When it comes to the world of adaptogens and stress-helping supplements, ashwagandha is one of the most talked-about. “Ashwagandha has been used for centuries for its medicinal properties,” says Kelsey Lorencz, RDN. “As an adaptogen, it has the ability to help our bodies better respond to stress." She explains that, unlike other adaptogens, ashwagandha has more of a sedative effect, which can be helpful for people who tend to be anxious or nervous. "While it can help your body respond to chronic and oxidative stress, it can also help with tension and nerves," she says.

Byrdie Researched & Approved

The Life Extension Optimized Ashwagandha, our best overall choice, is a powerful extract made from both the root and leaf of the plant recommended by one of our experts. For an affordable yet potent option, we loved the Himalaya Ashwagandha Capsules.

What to Look For in an Ashwagandha Supplement

Certified organic

When it comes to choosing an ashwagandha supplement, Kimberly Snyder, a plant-based nutritionist and holistic wellness expert, says that first and foremost, you want to make sure it has the USDA organic stamp. Brands can pretty freely include the words “natural” and “organic” on product packaging regardless of whether or not the formulas are fully organic, but the USDA stamp should ensure that the supplement is made from at least 95% organic ingredients.

Whole herb formulas

Snyder also recommends looking for supplements that contain the whole herb rather than herb extractions. This way, you can ensure you receive the maximum amount of benefits from the plant.

Properly grown and sourced

Where and how ashwagandha is grown will affect how efficacious it will be. “While ashwagandha can grow all around the world, traditionally black soil is considered the most ideal condition for this plant, which is where nature can concentrate its active compounds,” says Snyder. “One such place is the Nagori region of central India, where the high altitude, black soil, and limited rain and fertilizer allow the plant to flourish to its fullest potential.”

In addition to being grown in black soil, Snyder stresses the importance of going with a brand that understands that harvesting time is to be respected. “The fruits of the ashwagandha plant should be mature but not dried out, which is when the active principles are the highest.”

Of course, not all of this information may be listed on a product label, so be sure to do your research or reach out to a brand directly before making a purchase.

  • Can improve sleep quality

What We Don't Like
  • Reviewers note receiving less tablets than advertised

Ashwagandha is an herb that combats stress, which is often a major underlying cause of many sleep disorders, explains Tricia Pingel, NMD, a naturopathic physician specializing in stress and adrenal fatigue. That's why you'll also find that some ashwagandha supplements are formulated specifically to help with sleep, like this one. “This supplement is great for chronic insomnia due to stress,” she says. “It contains nutrients needed to restore proper sleep-wake cycles and to help improve both sleep quality and quantity. These include ashwagandha, L-theanine, epimedium, and phosphatidylserine from soy lecithin."

Additionally, it contains phosphatidylserine, a fatty substance produced by your body naturally and that’s incredibly important in your brain and spinal cord as it aids in the transmission of nerve impulses, adds Pingel. “As a supplement, it has been shown to support the body’s stress response, which is a very common cause of restless nights,” she says.

At $40 for 30 grams, the powder is a bit of a splurge, but we vote that it's worth it.

FAQ
  • What are the benefits of ashwagandha supplements?

    “The most notable benefit ashwagandha supplements offer is their effect on lowering stress levels,” says Bah. “The herb is classified as an adaptogen, which indicates its capability to normalize physiologic processes and thereby stabilize the body's response to stress. Studies suggest that ashwagandha not only lowers stress levels but provides the mind with protection against future stress—which is said to improve quality of life.”

    And ashwagandha may have other benefits. “Some people also use ashwagandha for improving thinking ability, reducing pain and swelling, and to increase libido,” says Bah.

  • Can you take ashwagandha supplements with other supplements?

    According to Snyder, you can take ashwagandha with other supplements. “To date, there are no major studies I’m aware of that show ashwagandha to have any interactions with other drugs or supplements,” she says. “However, if you’re concerned or on prescription drugs, you should always ask your doctor about taking any herbs.”

  • When should you take ashwagandha supplements?

    You can take ashwagandha at different times of the day, depending on your health goals. “If you’re looking to consume ashwagandha for general health promotion, it’s recommended to take it on an empty stomach in the morning,” says Snyder. “If you’re looking to gain bulk and strength, it’s recommended to consume ashwagandha after meals.”

  • How often should you take ashwagandha supplements?

    With ashwagandha, you can’t just pop a supplement and hope to feel chill immediately. You need to take it daily. “The key with ashwagandha and any other adaptogen is giving it time to work,” says Lorencz. “It can take up to 60 days of regular consumption to see and feel the benefits.”

  • Do ashwagandha supplements expire?

    Yes, they do. "As with any herbal or medicinal supplement, the longer it's exposed to air and sunlight, the less effective it will be,” says Lorencz. “It won't necessarily go bad at a certain date, but the longer it's exposed to the elements the more likely it is to decrease in effectiveness.” Keep your supplement, root, or powder in an airtight container and in a dark and cool location to help keep it potent as long as possible, she suggests.
