The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
Our editors have researched and taken clean supplements for years. These are our picks for ashwagandha supplements with natural, third-party tested ingredients that are gentle yet effective.
We could all use more stress support, couldn’t we? A little bit of stress can be ok — helping us stay motivated and focused during demanding situations. But that never-ending checklist of things you need to remember to do that won’t stop running through your head? Or the tension in your jaw, neck, or back? Or those stress-induced sleep problems? We could certainly do without those.
We love looking toward adaptogens for drug-free support for mental health — whether we’re looking for energy, clarity, relaxation, or mood lifting. And when it comes to managing stress and anxiety, ashwagandha is pretty much the gold standard in terms of adaptogens.
Ashwagandha is an evergreen shrub, the roots and berries of which have been used in traditional Ayurvedic medicine for millennia. Today, ashwagandha supplements typically come in capsule form (and sometimes powders or gummies), and often use potent extracts of the plant. They’re a great way to try out a more natural way to manage stress with little to no side effects.
Why are clean, third-party tested supplements important?
Clean, third-party tested supplements are essential for making sure you’re getting the ingredients you’re paying for and none of the extras you don’t want in a supplement — like artificial fillers, flavorings, or preservatives. We love when a supplement has super transparent sourcing and ingredient information — because we’re going to be paying for a supplement, we want to make sure it’s the best!
What are the benefits of taking ashwagandha?
Ashwagandha has been shown to lower anxiety, stress, and cortisol levels. It’s also been shown, through preliminary studies, to improve sleep quality. Like most adaptogens, it’s most effective when taken every day.
Is there anyone who should not take ashwagandha?
While ashwagandha appears safe and well-tolerated in research so far, we recommend talking to your doctor before starting any new supplement. Some experts say pregnant people and people with hormone-sensitive prostate cancer should avoid ashwagandha, and it might also interact with some medications or affect thyroid function.
What’s the best way to consume ashwagandha?
Preliminary studies so far on ashwagandha haven’t shown much regularity in terms of dosage or type of supplement, but the most common way to take the adaptogen is with a capsule or a powder. While it can typically be taken any time of day, we recommend taking it with food — right after breakfast or dinner, for example. Dosages vary from 150 to 500 milligrams daily, as different name-brand ashwagandha extracts have slightly different potencies. As always, speak to your doctor before adding new supplements to your diet.

The powder comes in a little glass jar that doesn’t take up much room in your pantry (and is reusable!), and it’s easy to add into your daily routine. Blend it into a smoothie or stir it into coffee or tea to experience its stress-relieving, focus-enhancing, and irritability-reducing effects. Each jar contains 72 servings and each serving delivers 600 milligrams of ashwagandha, making this one of the most potent forms on this list.

Active ingredients |Sensoril® (ashwagandha), holy basil, saffron, probiotics
Prices starting at |$54; $1.80/serving
Perelel Stress Support features a clinically studied, patented form of ashwagandha (Sensoril®) designed to help your body cope a bit better with everyday stress. Each daily capsule pairs ashwagandha with Affron® (a form of saffron extract) for mood and irritability support, holy basil, which is another adaptogen used to support stress levels, and a probiotic (Lactobacillus plantarum Lp815) to support the gut-brain connection. The result is a comprehensive blend for a more resilient stress response, stress-related sleep concerns, and steadier energy throughout the day. And it doesn’t cause drowsiness, so you can take the supplement any time of day. The product is rigorously third-party tested and made in an FDA-registered facility in the US, and it was developed by OB/GYNs and women’s health experts, so it’s uniquely tailored to the stresses women’s bodies undergo.
Customer Review | “This little capsule feels like a massive deep breath.

The result is a stress‑relief supplement that’s less of a quick fix and more of a total routine upgrade.
Customer Review | “I thought I would have to take the Stress Relief for a period of time before it worked but thankfully, it started working within an hour of taking it.

They add the adaptogen to a couple different blends, too.

8. NOW Foods
Best For | Pure ashwagandha capsules
Active ingredients |Ashwagandha

Another trusted and affordable supplement brand, NOW Foods has been family owned since 1968. Their simple, one-ingredient ashwagandha supplement is one of the most affordable options on this list. With nothing but 450 milligrams of ashwagandha in its pure form, the capsules actually aren’t as potent as some on this list that use highly concentrated extract versions of the adaptogen. The vegetarian capsule format suits people avoiding gelatin, and the suggested use — one capsule two to three times daily — allows you to adjust dosage based on your needs and tolerance. The capsules are made and quality tested in the US, and packaged in 100% recycled plastic bottles.


9. Pure Encapsulations
Best For | A high concentration of ashwagandha
Active ingredients |Ashwagandha
Prices starting at |$26; $0.47/serving
Each capsule of Pure Encapsulations’ ashwagandha supplement contains 500 milligrams of the KSM-66® version of ashwagandha extract. KSM-66® is a highly concentrated, full-spectrum form that uses only the plant’s root; it’s been extensively clinically studied, and its maker owns the entire supply chain starting at the farm level. The capsules contain no other active ingredient besides KSM-66®, and they’re one of the most high-value ashwagandha supplements on the market when it comes to potency versus cost — the capsules in the 120 size bottle come out to less than $0.40 per serving. Pure Encapsulations formulates without artificial colors, fillers, or preservatives, and they partner with TerraCycle to help users recycle materials that aren’t accepted in curbside recycling programs.
Customer Review | “I’ve tried several ashwagandha brands, some less pricey and some about the same price. Pure Encapsulations is by far the best. I take one every evening and I sleep much better. If I feel stressed during the day, I will take one and it just seems to calm the body down.” – Julie T. (Read more reviews.)
