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 everywhere from 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? You’ll want to take into account each supplement’s transparency, label accuracy, and absorption. Here’s what we landed on.

How We Picked Our Favorites

A good amount of evidence suggests that ashwagandha can be useful for helping to manage fatigue, improve focus, reduce anxiety, and maybe even help with sports performance.(1)(2)(3)(4)(5)(6)(7) So you’ve seen some studies, you’re convinced by the science, you’re in the market for a supplement, and you want to know how you land on the best ashwagandha pill? Every type of supplement has different ins and outs, but this 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 and some studies have seen benefits with lower doses, but it’s worth getting the most bang for your buck, here.

The most potent product we found delivered 2,100 milligrams per serving, and it’s important to look closely at the dosage as many competitors 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, but we made sure the top pick did.

black pepper

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 have 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 take it on faith that the label is accurate. Not everyone is happy with the system so a lot of top tier products have an external company test the product to ensure accuracy of the label and to 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, but 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 in accordance with organic standards.

Wrapping Up

Ashwagandha is a fascinating supplement with a wealth of research supporting it as a means to help the body combat stress and fatigue. We should emphasize that the scientific community isn’t unanimous, here — we simply need more research — but if you’re convinced that this Ayurvedic plant is worth experimenting with, we think we’ve landed on the best products for your needs.
