Whether it's a traffic jam, a problematic relationship, a shocking diagnosis, or a demanding boss, stress is something that no one can escape no matter how large or small the trigger is. Long-term stress can result in anxiety, affecting 6.8 million Americans, many of whom may manage it with medication.(1) However, a desire for better health without harmful side effects has caused 80% of people to turn to herbal medicines as a part of their primary care worldwide.(2)

That brings us to the best ashwagandha supplements—ashwagandha is a traditional Ayurvedic herb used medicinally in India to help with cognition and preserve youthfulness. A growing body of studies supports the herb's mood-enhancing benefits to help reduce cortisol (stress hormone) levels, as well as anxiety and depression.(3) And for athletes, the adaptogenic herb may enhance cardiorespiratory performance, according to a 2012 study.(4)

While further research needs to be done to confirm these potential benefits, if you tend to suffer nervousness, anxiety, or feel under pressure, an ashwagandha supplement may be right for you. We researched the best ashwagandha supplements and compiled a list of our favorites based on factors like price, dosage, certifications, and ingredients.

Best Overall Ashwagandha - Transparent Labs KSM-66 Ashwagandha

Transparent Labs KSM-66 Ashwagandha


  • Type: Capsule
  • Key ingredients: 600mg KSM-66 Ashwagandha Extract
  • Dosage: 1 capsule
  • Certifications: National Sanitation Foundation (NSF)-Certified


You can find ashwagandha as an ingredient in plenty of stress-control supplement products, but often in less-than-optimal dosages, or alongside other ingredients that you may or may not be interested in taking. But if you’re trying to see if ashwagandha is a fit for you and your lifestyle, it makes sense to treat it as an experiment with as few of these extra variables as possible. That’s where a simple, high-quality ashwagandha supplement like this one from Transparent Labs can be just what you’re looking for.

This is a simple, straightforward single-ingredient ashwagandha capsule in a research-backed dose, using the preeminent patented, organic version on the market, KSM-66. No extra pills to swallow, no other ingredients to worry about. It’s just what it says it is.

What We Like

  • Patented version of ashwagandha, KSM-66
  • Research-backed dosage for stress-control
  • Reasonable price-per-dose, especially for a patented ingredient

What We Don't Like

  • While the once-daily dosage aligns with recommendations for stress control, it doesn’t work for blood sugar-management recommendations of 2-3 smaller doses per day

BUY: Transparent Labs KSM-66 Ashwagandha

Best Gummy Ashwagandha Supplement - XWerks Ashwa

Xwerks Ashwa Gummies


  • Type: Softgels
  • Key ingredients: Ashwagandha extract, Gamma-aminobutyric acid (GABA, L-theanine, and Lemon balm extract
  • Dosage: 2 softgels
  • Certifications: National Sanitation Foundation (NSF)-Certified


Leave stress behind with XWerks Ashwa. We like that it comes in the form of soft gels which are easier to swallow. Plus, it may help increase testosterone, improve physical performance, and promote better sleep—benefits that are backed by research and a range of different studies, like a double-blind, placebo-controlled study that found decreased stress levels in participants who took ashwagandha regularly.(5)

XWerks Ashwa is also affordable, at just $19.00 for a 1-month supply. However, we do want to note that this supplement isn’t the best choice for those following a low-sugar diet. Each serving size (two soft gels) contains 6 grams of sugar.

What We Like

  • Great value for cost per serving
  • Gluten-free, non-GMO and vegan
  • Reviewers say it helps with sleep
  • Comes in the form of soft gel capsules that go down easier than pills

What We Don't Like

  • Contains 6g of sugar, including added sugars

BUY: Xwerks Ashwa

Best Greens Powder with Ashwagandha - Athletic Greens AG1

Athletic Greens AG1


  • Type: Powder
  • Key ingredients: Vitamins, greens, nutrient blends
  • Dosage: 1 scoop
  • Certifications: NSF-Certified for Sport


The popular greens supplement AG1 by Athletic Greens contains such a wealth of ingredients, it’s forgivable if you overlook a few of them on the epic nutrition facts label. But scroll past the vitamins and minerals and into the "Nutrient-Dense Extracts, Herbs, and Antioxidants" and sure enough, you’ll see that the greens contain a 5:1 extract of ashwagandha.

Is this the exact amount that you want to take? It’s hard to say since that part of the AG1 blend doesn’t itemize individual ingredients. So, if you’re really set on experiencing the benefits of ashwagandha specifically, supplementing with another dedicated source might be a good idea. But if you’re looking for a nutritional gap-filler that also includes these popular stress control ingredients, AG1 fits the bill.

What We Like

  • Doubles as a multivitamin and multi-mineral
  • Lots of third-party testing and certified Safe for Sport
  • Vegetarian and vegan-friendly

What We Don't Like

  • Plenty of the nutritional label resides in proprietary "complexes" without specific dosages listed
  • Price per serving gets high, especially if you also want to take any dedicated single ingredients on the side

BUY: Athletic Greens AG1

The product is friendly to those who need gluten-free and lactose-free supplements, but it's not free of soy, coconut, or tree nuts. So if you have those food allergies, you'll want to choose a product that's a better fit for you. And while the product is certainly affordable, it contains added sugars, additives, and food dye.

Benefits of Ashwagandha

Ashwagandha May Support Shut-Eye

In one study, 60 adults with insomnia were split into two groups and given 300 milligrams of ashwagandha or a placebo each day for 12 weeks.(10) The study results found that ashwagandha significantly improved sleep onset, total sleep duration, quality, and reduced anxiety.

Ashwagandha May Alleviate Stress, and Anxiety

Ashwagandha is known for its help in naturally lowering stress levels. A small study of 58 adults taking 250 or 600 milligrams of ashwagandha extract for eight weeks saw significantly lower levels of perceived stress and cortisol than participants taking a placebo.(11) Furthermore, the ashwagandha group experienced better sleep than the placebo group. Another study of 60 adults found that taking 240 milligrams of ashwagandha extract daily for 60 days showed significant decreases in anxiety compared with those taking a placebo.(3)

Ashwagandha May Boost Athletic Performance and Muscle Strength

If you're an athlete or sports enthusiast, you may be interested in hearing the latest ashwagandha research on physical performance. A research analysis examined 12 studies of adults taking between 120 mg and 1,250 milligrams of ashwagandha every day.(12 ) At the study's end, researchers suggested the herb may enhance physical performance, strength, and oxygen utilization while exercising. In addition, a study of men taking 600 mg of ashwagandha each day and completing resistance training for eight weeks experienced significantly better muscle strength and size than the placebo group.(13)

What to Consider When Buying Ashwagandha Supplements


Studies have shown ashwagandha may help lower stress and anxiety and improve sleep in adults.(3,14,15) Though it has promising effects, certain types of ashwagandha may be more potent than others. Companies may market themselves as having the best ashwagandha supplement, however, not all ashwagandha is created equal. The best types of ashwagandha are KSM-66 and Sensoril.

  • KSM-66: Supplements made with KSM-66 ashwagandha source the extract from Ixoreal Biomed.(16) Supported by over 20 clinical studies, KSM 66 ashwagandha uses the roots only of the herb and, through careful processing measures, maintains a full spectrum of bioactive herbal constituents that offer health benefits. It has a 5% concentration of withanolides, its anti-stress compounds.(17)
  • Sensoril: Supplements made from Sensoril ashwagandha source the extract from a company called Natreon. Ten clinical studies support using the roots and leaves of ashwagandha with 10% withanolides.(18)

There's no formal consensus of which type is superior, as you'll find opinions vary, however, the bottom line is that if you're looking for a supplement that offers the most well-researched types of ashwagandha, you might choose one with KSM-66 or Sensoril.


Ashwagandha supplements come in a variety of forms—tinctures, capsules, powders, gummies, and powders alike. If you have swallowing problems, you may choose a tincture. If you're limiting added sugar intake, you may select capsules over gummies. A powder form could be an ideal addition to your morning smoothie blend. Whatever the case, consider the form you'll be able to take every day.

Key Ingredients

There's nothing wrong with looking for a supplement that's 100% ashwagandha—by now, we know that the adaptogenic herb has many benefits. Certain ashwagandha brands promote sleep by combining ashwagandha with sleep-inducing ingredients like lavender and melatonin. Other supplements may be more appealing because they've added crucial nutrients like vitamin D or choline to their blends for immunity and cognitive support.


Supplement dosages come in a wide range, some much higher than others. If you're more of a one-and-done type, we recommend finding an ashwagandha supplement with a small dosage because others may suggest you take four capsules, which can be a lot to handle. Some dosages recommend taking the serving size twice daily, which is something else to consider.


To ensure an ashwagandha supplement is of high quality and free of contaminants, we recommend purchasing one manufactured in a GMP facility that’s third-party tested. GMP facilities have high standards regarding cleanliness, equipment, employees, and operating procedures. Third-party tested supplements are sent to an outside company and tested to ensure they contain the stated amount of ingredients and are free from contaminants.

Most often than not, experiencing the benefits of supplements is a long-term game. It could take several weeks for you to see results from using ashwagandha. One study saw results after participants took ashwagandha for ten weeks.(21) On the other hand, one brand in our list claims you'll feel its effects within an hour.
