9 RD-Recommended Ashwagandha Supplements for 2025

We Reviewed Ashwagandha Supplements: Here Are the Top 9 Dietitians Recommend in 2025

Ashwagandha (also called winter cherry) is an herb that has been used for centuries in traditional medicine to support the nervous system. “Ashwagandha is an adaptogen, [which means it is] a type of plant that helps the body adjust to stressful conditions,” explains Bay Area registered dietitian Brenna Howsepian, RDN, CDCES. The ashwagandha root contains helpful compounds called withanolides, which are believed to be behind its health benefits. These compounds are known for reducing anxiety, easing stress, and improving sleep quality.

“While adaptogens have gained popularity in recent years, they have been used for thousands of years as tonics to restore balance and promote overall well-being,” says Howsepian. As stress is a well-known contributor to chronic disease, more people are looking for natural support, and supplement brands are paying attention.

More interest means more products are available, but it also means you also have many more products to decide between, which can be overwhelming.

To help you discover the best ashwagandha supplements, we combined dietitian insights and research with my experience as a dietitian using ashwagandha with clients. We focused on products that contain scientifically supported ingredients, have been verified by third-party testing, and meet high-quality standards. Here are our top nine picks for ashwagandha supplements in 2024.

Our Top Picks for Ashwagandha

When to Consult Your Doctor

Everyday Health recommends speaking with your doctor or healthcare provider before adding any supplement to your diet, to make sure it is safe and appropriate for your individual health needs.

This is especially important for certain groups of people who should avoid ashwagandha. If you are pregnant or have diabetes or certain autoimmune diseases, it is crucial that you consult with a healthcare professional before using ashwagandha. These supplements can be powerful and might interact with certain medications or health conditions, so getting personalized advice from your doctor can help ensure safe and effective use that is tailored to your specific health circumstances.

Best High Potency

Pure Encapsulations Ashwagandha

$26.20 at Amazon

Pros

  • High dose per capsule
  • Contains a patented form of ashwagandha used in research
  • cGMP and NSF certified
  • Free from common allergens, non-GMO, gluten-free

Cons

  • Larger capsules may be harder for some to swallow
  • Form: Capsule
  • Dose: One capsule daily
  • Amount of ashwagandha per dose: 500 mg (2.5 percent withanolides)
  • Other notable ingredients: None
  • Diet considerations: Gluten-free, non-GMO, allergy-friendly
  • Third-party tested: Yes
Pure Encapsulations is our top pick for a high-potency ashwagandha, with its high concentration of withanolides to support stress. This product contains 500 milligrams (mg) of KSM-66 ashwagandha extract, a patented form of ashwagandha used in research studies that show its benefits for reducing stress and anxiety.


Howsepian appreciates Pure Encapsulations for its simple formulations and commitment to quality. “Clients considering ashwagandha are typically seeking extra support during a stressful period,” she says. “The dosage is manageable and contains 2.5 percent withanolides, the research-backed concentration shown to help reduce stress and anxiety by lowering cortisol levels and boosting serotonin in healthy individuals.” This 2.5 percent concentration of withanolides refers to the proportion of active compounds in the ashwagandha extract that is responsible for its benefits.


In addition to offering a hefty dose of stress-busting compounds, this product adheres to Current Good Manufacturing Practice (cGMP) standards. It’s certified by the National Sanitation Foundation (NSF), which means it’s third-party tested for product purity and safety. It’s also gluten-free, free from common allergens (wheat, soy, dairy, eggs, peanuts, tree nuts, sesame), artificial ingredients, and genetically modified organisms (GMOs).


One potential downside is that some users may find the capsules a bit large, which might be a consideration for those who have difficulty swallowing pills. However, each capsule contains a reasonable 500 mg of ashwagandha — and you can easily increase the dosage by taking more if needed.

Best Adaptogen Combo

Integrative Therapeutics Cortisol Manager

$24.46 at Amazon
$25.75Now 5% Off

Pros

  • Includes other adaptogens for additional stress support
  • Contains a form of ashwagandha studied in research
  • cGMP and NSF certified
  • Free from gluten, dairy

Cons

  • Amount of ashwagandha not disclosed
  • Form: Tablet
  • Dose: Two tablets
  • Amount of ashwagandha per dose: Unknown
  • Other notable ingredients: L-theanine, magnolia bark, phosphatidylserine
  • Diet considerations: Dairy-free, vegan, gluten-free
  • Third-party tested: Yes
Integrative Therapeutics Cortisol Manager stands out as the best ashwagandha supplement with extra botanicals, including L-theanine, phosphatidylserine, and magnolia bark. It is designed to offer a comprehensive product to support stress relief and relaxation. “L-theanine has been shown to alleviate stress symptoms, reduce sleep disturbances, and enhance cognitive function, while phosphatidylserine also shows improvements in cognitive performance,” says Howsepian. Magnolia bark extract may further help with stress, as some research suggests that it interacts with receptors in the brain that promote a feeling of calm.


Cortisol Manager uses a patented form of ashwagandha called Sensoril, which has been used in research, including one study where it significantly reduced serum cortisol levels and stress levels compared to a placebo.


Howsepian uses this product as an additional self-care tool to promote restful sleep and better focus in her clients. “Integrative Therapeutics Cortisol Manager is a go-to recommendation for those in a stressful season of life,” she says. Free from gluten, dairy, and wheat, Cortisol Manager is also made in a cGMP-registered facility and is NSF-certified. Its ashwagandha is part of a proprietary blend with L-theanine, which means the amount of each ingredient in the blend isn’t disclosed, so we don’t know exactly how much ashwagandha is in the product. But overall, the use of evidence-based, natural ingredients makes it a valuable choice for those who want a combination supplement to support stress.

Best Liquid

MaryRuth’s Organic Ashwagandha Root

$16.11 at Amazon
$17.90Now 10% Off

Pros

  • Easy to swallow liquid form
  • Third-party tested, Clean Label Project certified, cGMP certified

Cons

  • May taste too sweet for some
  • Form: Liquid
  • Dose: 0.5 milliliters

MaryRuth’s Organic Ashwagandha Root is our top choice for the best liquid ashwagandha supplement, offering a convenient, high-quality alternative to pills. “A liquid formulation is convenient for people who have trouble swallowing capsules,” shares Raksha Shah, RDN. “I recommend this to my clients because it is easy (one dropper) and not two to three pills to swallow.”

This liquid extract utilizes glycerin and water instead of alcohol (as many herbs traditionally use) for extraction, making it good for those who wish to avoid alcohol. It has 590 mg of organic ashwagandha root per dose, and the supplement is non-GMO, vegan, gluten-free, nut-free, dairy-free, and soy-free.

MaryRuth’s is committed to quality with third-party testing, plus they are cGMP certified and Clean Label Project certified (a nonprofit that takes third-party testing even further, testing for hundreds of toxins and contaminants).

While some reviews describe the taste as overly sweet, the product’s overall efficacy and convenience make it a worthy investment for those seeking stress relief and cognitive support in an easy-to-consume format.

Fair Trade certification supports the farmers who grow the ashwagandha and ensures that the farming methods help protect the environment and promote social equity.

“I recommend Organic India to my patients for balancing stress and energy during the day and achieving restful sleep at night,” says Lea Wetzell, a Minnesota-based licensed nutritionist and certified nutrition specialist. “It’s especially beneficial for menopausal women navigating life’s many stressors.”


Organic India third-party tests each batch of its herbs for contaminants and confirms product integrity and identity to ensure that what the label says matches what’s in the bottle.

Best Gummy

Gaia Herbs Ashwagandha

$33.29 at Amazon

Pros

  • Tasty gummies sweetened with fruit
  • No refined sugar or artificial sweeteners
  • Organic, non-GMO, B Corp certified

Cons

  • Contains 5 grams of sugar per serving
  • Form: Gummy
  • Dose: Three gummies daily
  • Amount of ashwagandha per dose: 600 mg organic ashwagandha root extract
  • Other notable ingredients: Cinnamon, ginger root
  • Diet considerations: Organic, vegan, allergen-friendly
  • Third-party tested: Yes

Gaia Herbs earns a place as the best gummy ashwagandha supplement thanks to its effective but simple product formulation to support stress reduction. Unlike many gummies with added refined sugar, these gummies are sweetened naturally with apple juice, dates, blueberry, cinnamon, and ginger.

As a Certified B Corporation, Gaia Herbs upholds high standards of product quality and corporate responsibility with its organic and non-GMO gummies. Each serving delivers 600 mg of organic ashwagandha root extract. The product is also allergen-friendly and free from corn, dairy, gluten, peanuts, shellfish, soy, tree nuts, and yeast.

Even though they are sweetened naturally, these gummies contain 5 grams of sugar per serving, which could be a downside for those keeping tabs on total intake, including those managing health conditions like diabetes or those concerned about dental health. But for many, popping three gummies each day feels easier than taking a pill, making this product an accessible option for stress relief.

$8.50 at Amazon
$8.95Now 5% Off

Pros

  • Most affordable on our list
  • cGMP certified with third-party and in-house testing
  • Allergen-friendly, gluten-free

Cons

  • Not ideal for those who don’t like to swallow capsules
  • Form: Capsule

These capsules contain 2.5 percent withanolides, the same research-backed concentration used in other formulas on our list to support stress reduction and better sleep.

It’s appropriate for multiple dietary needs, including kosher, dairy-free, egg-free, nut-free, soy-free, vegan/vegetarian, and gluten-free diets. It’s also made in a cGMP-certified facility with third-party testing and strict in-house testing.

Once again, if you don’t like swallowing capsules, this isn’t an ideal choice. But given the cost and the fact that this product is standardized to contain a specific amount of withanolides, it’s a solid choice at an affordable price.

Best for Sleep Support

Physician’s Choice KSM-66 Ashwagandha

$26.97 at Amazon
$29.97Now 10% Off

Pros

  • Contains a form of ashwagandha studied for sleep
  • Black pepper may aid in nutrient absorption
  • cGMP, NSF certified, non-GMO, organic

Cons

  • Black pepper can be a gut irritant
  • Form: Capsules
  • Dose: Two capsules daily
  • Amount of ashwagandha per dose: 1,000 mg (5 percent withanolides)
  • Other notable ingredients: Black pepper
  • Diet considerations: Gluten-free, vegan
  • Third-party tested: Yes
Physician’s Choice KSM-66 Ashwagandha is our top pick for sleep support, thanks to its effects on stress reduction and sleep improvement. This supplement uses KSM-66, a highly researched form of ashwagandha that is known for supporting stress reduction and lowering cortisol levels (a hormone the body releases in response to stress).


Research studies support the effectiveness of KSM-66 for better rest, with one study showing significant improvements in sleep quality metrics like sleep onset and total sleep time over eight weeks.


Shah reports that she recommends this product, especially after seeing improvements in her own sleep. “The black pepper included in the formulation improves the bioavailability of the ashwagandha,” she adds. Bioavailability means the body can better absorb and use the supplement, and black pepper may improve overall nutrient absorption.


This product is also organic, non-GMO, gluten-free, vegetarian, and vegan. Additionally, it is produced in a cGMP-certified facility and has an NSF certification to ensure purity and potency. While some people may avoid black pepper if it irritates their stomach, it’s such a small dose that it likely isn’t a problem for most.


Best for Physical Performance

Jarrow Formulas Ashwagandha

$17.09 at Amazon
$26.99Now 37% Off

Pros

  • Contains a form of ashwagandha studied for exercise performance
  • cGMP and NSF certified
  • Gluten-free, vegetarian, allergen-friendly

Cons

  • Capsules may be hard for some to swallow
  • Form: Capsule
  • Dose: One capsule twice daily
  • Amount of ashwagandha per dose: 300 mg
  • Other notable ingredients: None
  • Diet considerations: Gluten-free, allergen-friendly, vegetarian, non-GMO
  • Third-party tested: Yes
Jarrow Formulas Ashwagandha is our top pick for enhancing physical performance, thanks to its use of KSM-66. Specifically, 300 mg of this well-researched ashwagandha extract has been shown to support endurance and recovery, making it an ideal option if you’re an athlete or fitness enthusiast.

Some research also suggests that ashwagandha may help with physical performance and recovery by acting as an anti-inflammatory and an antioxidant.

Free radicals, compounds that can cause damage to cells, are produced as a byproduct of exercise, but antioxidants help neutralize them. “Ashwagandha also is reported to help with overall inflammation, swelling, fatigue and recovery time,” says Bess Berger, RDN, owner of Nutrition by Bess. It also may help by increasing oxygen uptake and muscle strength.


This product is gluten-free and vegetarian, as well as free from common allergens (wheat, gluten, soybeans, dairy, egg, fish/shellfish, peanuts/tree nuts, and sesame). Jarrow Formulas products are also produced using strict quality testing for purity and potency, with cGMP certification by NSF.

Best Multivitamin With Ashwagandha

Nature Made Multi + Ashwagandha

$46.99 at Amazon

Pros

  • Contains 21 essential nutrients plus ashwagandha
  • cGMP certified and third-party tested
  • Gluten-free

Cons

  • Only contains 125 mg ashwagandha
  • Not a comprehensive multivitamin
  • Form: Capsule

  • Amount of ashwagandha per dose: 125 mg Sensoril (root and leaf extract)
  • Other notable ingredients: 21 essential vitamins and minerals
  • Diet considerations: Gluten-free

Nature Made Multi + Ashwagandha is the top choice for those seeking a convenient multivitamin that also offers stress relief. This unique blend provides daily nutritional support and stress management in a single capsule, perfect for busy people who want to simplify their supplement routine.

“I love the Nature Made Multi + Ashwagandha capsules, as they contain 125 mg of Sensoril ashwagandha extract plus 21 essential vitamins and minerals,” says registered dietitian Melissa Mitri, owner of Melissa Mitri Nutrition. “Sensoril is a form of ashwagandha tested in several research studies for its potential health benefits.”


These capsules offer a range of 21 foundational and essential vitamins and minerals, such as vitamin C and vitamin D, supporting healthy immune function and bone health.


Mitri also appreciates that Nature Made uses quality ingredients and is a top pharmacist-recommended vitamin and supplement brand. Nature Made’s manufacturer, Pharmavite, performs rigorous testing on all raw materials and the finished product.

Keep in mind that this multi is either missing or low in a few minerals you may want in your multivitamin, such as calcium. And while some may want higher doses of ashwagandha than 125 mg, this product is a good starting point, and you can always add additional ashwagandha if needed.

How We Reviewed the Best Ashwagandha Supplements

Our review process aims to provide trustworthy and comprehensive evaluations of ashwagandha supplements. We closely reviewed different supplement brands and products for a diverse and inclusive selection.

Each product was evaluated based on ingredient quality, effectiveness, and brand transparency. We also consulted five registered dietitians:

  • Melissa Mitri, RD
  • Brenna Howsepian, RDN, CDCES
  • Raksha Shah, RDN
  • Lea Wetzell, LN, CNS

As a dietitian trained in integrative and functional nutrition, I have extensive experience utilizing botanicals like ashwagandha in my practice. I regularly review supplements to ensure that they meet the needs of my clients and myself.

What to Look for When Buying Ashwagandha Supplements

Choosing the right ashwagandha supplement can significantly impact its effectiveness and safety. With a variety of options available, focusing on the following can help you select a product that meets your needs:

  • Form of ashwagandha: If you’re searching for an ashwagandha product, Mitri suggests looking for KSM-66 or Sensoril ashwagandha on the label. “These are the two most well-researched forms for effectiveness and safety,” she says. That doesn’t mean products without these forms won’t be effective, but if you’re unfamiliar with the product, this can help you feel confident in your choice.

  • Dosage: “Look for a dose of at least 120 mg, which is the minimum dose seen to produce health benefits in research studies,” says Mitri.

  • Third-party testing: “Look for signs the brand undergoes regular product testing for quality and safety or is third-party certified,” advises Mitri.
  • Additional ingredients: Shah suggests looking for complementary ingredients, such as black pepper, which may enhance absorption.
  • Certification: If you avoid gluten or have other dietary restrictions, consider additional certifications. “Check for additional certifications such as organic, non-GMO, or gluten-free for added assurance of quality,” says Shah.

What Is Ashwagandha?

Ashwagandha (Withania somnifera), also known as Indian ginseng and winter cherry, is an herb that has been used for thousands of years to support the body’s resilience to stress. “These herbs exert complex effects on multiple systems, enhancing the body’s resilience to stress, improving mental and physical performance, and boosting endurance and strength,” says Howsepian.


What Are the Benefits of Ashwagandha Supplements?

The primary benefit of ashwagandha is that it may help the body be more resilient to stress. “Research has shown ashwagandha may help reduce perceived stress and anxiety, improve the ability to fall and stay asleep, and improve athletic performance when taken daily,” shares Mitri.


Howsepian adds that scientists have identified numerous beneficial components of the ashwagandha plant, especially withanolides that help protect cells from oxidative stress and damage to cells from free radicals.


Ashwagandha may also help improve physical activity, supporting muscle strength, lung capacity, and inflammation. “Some research shows increased upper body strength such as for bench presses, as well as increased breathing and leg extensions, after taking it for just two to four weeks,” says Berger.


Who Should Not Take Ashwagandha Supplements?

Wetzel explains that while ashwagandha has benefits, it’s not for everyone. Ashwagandha is likely not safe for the following people:

  • Women who are pregnant or breastfeeding
  • People with thyroid disorders
  • People with autoimmune conditions
  • People taking medications for diabetes
  • People taking blood thinning medication
  • People with hormone-sensitive prostate cancer


What Are the Potential Side Effects of Taking Ashwagandha Supplements?

Ashwagandha is generally well tolerated by most people, but some people may experience side effects. According to Mitri, the most commonly reported side effects from taking ashwagandha are drowsiness, stomach upset, nausea, and diarrhea. “While rare, there have been cases of liver damage with high doses,” she adds. “While ashwagandha is typically well tolerated in most people for up to three months of use, more research is needed into its overall safety and effectiveness for longer-term use.”


If you notice any side effects, stop taking the supplement and check with your doctor.

FAQ

Are there different kinds/forms of ashwagandha supplements?
“Ashwagandha comes in various forms, each catering to different preferences and uses,” says Wetzel. Capsules, tea, powdered whole herbs, extracts like KSM-66 or Sensoril, liquids, and gummies are all options.
Berger explains that the best time to take ashwagandha supplements depends on your needs. “Some prefer morning or before working out, reporting that it gives them a boost. Others prefer evening and say it relaxes them before bed. It’s best to experiment and see which best fits your lifestyle.”
There’s no standard dose for ashwagandha, says Mitri. “Most studies have tested doses between 120 and 600 mg daily, with a few as high as 1,250 mg,” she explains. “Individual responses can vary to different doses, so the recommendation is to start low and increase the dose as needed based on your response.”
Shah explains that it can take a few weeks to notice benefits from ashwagandha supplements. “Based on my experiences, you can see noticeable changes within two to six weeks of consistent use,” she says.
