Ashwagandha (Withania somnifera) is a plant in the nightshade family with a long history of use in Ayurvedic medicine. It’s considered an adaptogen: a product that might help the body to manage stress, whether that be stress from exercise or stress from a tough day at the office. While it’s currently difficult to work out the ideal dosage — studies have seen positive effects from dosages anywhere between 50 to 500 milligrams. A good amount of research suggests that ashwagandha may have anti-anxiety effects, help to manage fatigue, reduce levels of cortisol, and maybe even improve athletic performance.

So which brands have produced the best supplements? We sifted through the market to account for each supplement’s transparency, label accuracy, and absorption. Here are the ones that stand out from the rest of the field:

Best Ashwagandha Gummies

Xwerks Ashwa provides a whopping 1,500 milligrams per two-gummy dose. The gummies come in a delicious strawberry flavor, and you only need to take two per dose. They’re gluten-free, non-GMO, and vegan, but they do contain some added sugar, so they aren’t calorie free — each serving has six grams of sugar and 15 calories. It also states on the label that the product contains three percent withanolides — the active ingredient in ashwagandha. If you’re vegan and want a tasty product to keep you consistent with your ashwagandha supplementation, this is a great pick for you.

How We Decided Our Picks

A good amount of evidence suggests that ashwagandha can be useful for helping to manage fatigue, improve focus and mindset, reduce anxiety, and maybe even help with sports performance. (1)(2)(3)(4)(5)(6)(7) After reading the studies and following the science, how does one land on the best ashwagandha supplement? Here is what we focused on.

Ashwagandha Content

How much ashwagandha should you demand from your supplements? The truth is that there’s currently no real consensus on the ideal dosage. Some studies have seen benefits with lower doses. The most potent product we found delivered 2,100 milligrams per serving. Many reasonable competitors’ supplements contain well under 1,000 milligrams.

Withanolide Content

This is the name for metabolites found in ashwagandha and other members of the nightshade family. Research suggests that they’re the primary active ingredient in ashwagandha, and they’ve been linked to the plant’s myriad benefits. Very few companies put this on the label, so we didn’t penalize too harshly. However, bonus points to the options that did print that information on their label.

Black Pepper Extract

Most of these products contain black pepper extract (sometimes called piperine or BioPerine®, a trademarked variant), as it may help to increase absorption. Research published in Critical Reviews in Food Science and Nutrition, Expert Opinion on Drug Metabolism & Toxicology, and Planta Medica found that the addition of piperine can help the intestines to uptake anti-inflammatory compounds. (8)(9)(10)

Third-Party Testing

The FDA doesn’t really monitor nutritional supplements, so consumers have taken it in faith that the label is accurate. Not everyone is happy with the system, so many top-tier products have an external company test the product to ensure accuracy of the label and make sure there are no heavy metals or other contaminants present.

Organic Certification

It’s unlikely that this affects the product’s potency, but it’s clear that a large portion of customers prefer their ashwagandha to be certified organic, so we made sure to include it as a feature. There are a variety of different certifications, though — many feel the USDA is the gold standard. Still, there’s also Organic Certifiers, and there’s the “made with organic ingredients” label, which means at least 70 percent of the ingredients need to be produced per organic standards.
