Best Ashwagandha Supplement Overall: Transparent Labs KSM-66

Our Thoughts on Transparent Labs KSM-66

Transparent Labs KSM-66 is our pick for the best overall ashwagandha supplement because it combines a clinically validated dose of the most researched ashwagandha extract with third-party testing and transparent labeling. Users can trust they’re getting a pure and potent product with a simple, effective formula.

Kayla tested this supplement, rating it a 5 out of 5 for her first impressions. “The bottle looks like a typical capsule container, it’s neither huge nor too small. It seems portable enough to toss in a gym bag or travel kit without being too bulky,” she said. The lid is screw cap, which Kayla had no issues opening or closing. “Transparent Labs is great about keeping their packaging simple and readable,” she added. Kayla rated the ease of instruction as a 5 out of 5, too.

The serving size is one capsule daily. “They look to be standard capsules in terms of size and construction,” Kayla said. “The gelatin capsule is a little harder, so definitely need to take this with water,” she noted, rating it a 3 out of 5 for swallowability. Kayla didn’t notice any taste or smell with this product, and noticed no digestive issue after testing it.

Overall, Kayla likes that Transparent Labs uses KSM-66 in their product, since it’s a well-studied, root-only extract with good clinical backing, which gives her confidence in the formulation. She also appreciated the low capsule count per serving, and the lack of stimulants in this product.

Best Ashwagandha Supplement for Weight Loss: Hunter Evolve Focus

Our Thoughts on Hunter Evolve Focus

Hunter Evolve Focus earns our pick for the best ashwagandha supplement for weight loss because of the addition of acetyl-L-carnitine, as recent studies show L-carnitine supplementation may help support weight, BMI, and waist circumference reduction when combined with lifestyle changes. However, it’s important to note: While L-carnitine has potential as an tool for weight management (though more research is needed), ashwagandha supplements are not directly designed or widely backed as weight-loss products. 

“When I first saw the Hunter Evolve Focus packaging, I sensed a premium, modern-nootropic vibe because of its sleek, dark labels, and clean fonts,” Kayla said. “Their website is a little basic, and it feels like a smaller brand. When purchasing, I might be a little skeptical at first,” she added. “The packaging is a little large overall, but since each serving size is six capsules, I can see why it’s so big,” Kayla said, rating this product a 3 out of 5 for her first impression.

“The directions state to take two capsules three times daily with a glass of water and food. For optimum results, take daily and consistently. It also includes a warning label that says do not exceed dose and it’s for adults only. Also, this formula does have 100 mg of caffeine (for the full six capsules) so keep this in mind if you are caffeine sensitive,” Kayla said. She rated ease of understanding and following the instructions a 3 out of 5.

Kayla rated the swallowability of the capsules a 3 out of 5. “Taking six capsules daily or two capsules three times daily seems a little excessive. However, if you are a coffee drinker and use that to stay focused, it’s not really different than having two or more cups of coffee. I don’t know if this would work for my lifestyle per se, as I’m not great at eating three square meals daily but if it’s something you want to prioritize, I think the two capsules are doable per meal,” Kayla explained. “They aren’t large and have a gelatin shell which is typically easier to swallow.”

While the product had an earthy smell, it didn’t have any noticeable flavor and was easy to swallow. Kayla gave side effects a rating of 5 out of 5, saying, “I didn’t notice anything after taking this product. It states to take it consistently to start seeing results. I am not caffeine sensitive, so I think the biggest thing users want to watch out for is a jittery feeling from that added ingredient.” This product probably isn’t ideal for those who are sensitive to caffeine. In that case, we recommend Transparent Labs KSM-66.

Best Budget Ashwagandha Supplement: Nutricost Ashwagandha

Our Thoughts on Nutricost Ashwagandha

Nutricost Ashwagandha is our selection for the best budget ashwagandha supplement because it delivers a potent daily dose, clear ingredient labeling, and third-party testing for an impressively low price of 14 cents per serving. For professionals seeking stress relief and focus without extra costs or complicated blends, Nutricost’s straightforward formulation stands out. 

Kayla tested Nutricost Ashwagandha Gummies, giving them a 5 out of 5 for first impressions. “When I first received the bottle, I liked the simple, clean aesthetic. The container is a fairly typical plastic jar, with a screw-top lid and clear labeling. It doesn’t feel premium or luxe. I also like how the dosage info is easy to spot. It’s compact enough to throw in a gym bag or a travel toiletry kit. The bottle is not overly bulky,” she said.

She rated the ease of understanding the instructions a 5 out of 5. “The dosing instructions are straightforward: ‘Take two gummies daily or as directed by your healthcare professional.’” 

The gummies earned a 5 out of 5 for swallowability. “I like that the serving is modest with only two gummies,” Kayla wrote. “The size of the gummies are small and they have a nice texture. The gummy isn’t sticky or tough!”

“The gummy tastes like candy in a good way. I don’t taste a supplement or medicine in it at all,” she said. “Just a slightly sweet, soft, chewable gummy.” She rated the taste a 5 out of 5. 

In terms of side effects, Kayla rated her experience a 5 out of 5, saying, “I did feel a little more relaxed after taking the gummies. I didn’t feel sleepy or drowsy, just more calm overall.”

Best Ashwagandha Supplement for Sleep: Jacked Factory KSM-66

Our Thoughts on Jacked Factory KSM-66

Jacked Factory KSM-66 is our pick for the best ashwagandha supplement for sleep because it uses a high-quality, research-backed dose of KSM-66, which has been shown to potentially help improve sleep quality and reduce stress. In a 2020 clinical study, adults supplementing with KSM-66 experienced significant improvements in overall sleep quality and mental alertness upon waking compared to placebo. 

Kayla rated this product a 5 out of 5 for first impressions. She liked Jacked Factory’s sleek bottle and metallic label, noting it had a clean and professional look. This one also comes with an easy-to-use screw top, though the container is a bit larger than some of the others on this list. 

“The recommended dosage is one capsule per day, providing 600 milligrams of KSM-66 Ashwagandha. The directions were written pretty small on the label and I struggled for a second to find and read them,” Kayla said. “However, I looked again and they also had a little picture diagram above the directions of one capsule and one glass of water.” Thanks to the addition of the diagram to assist users in understanding the directions, our tester gave a 5 out of 5 score in this area. 

Kayla rated swallowability of this product a 5 out of 5. One capsule is very managable, according to Kayla, especially considering they’re fairly standard pill size. She also gave the taste a 5 out of 5, saying, “The product has zero taste, but it does smell slightly sweet and slightly bitter. I can’t quite put my finger on what it smells like, but overall, it does not impact the taste.”

“I didn’t notice any major side effects or results from this product,” Kayla said. “I may have felt slightly more relaxed overall, but maybe a little more sleepy feeling as well. I think overall the ashwagandha did have an effect on me, but think with a caffeine additive it would be better to create more energy and focus.” We suggest folks seeking a great ashwagandha supplement with caffein in the mix take a look at Hunter Evolve Focus instead.

Best Vegan Ashwagandha Supplement: Future Kind Super Plant Complex

Our Thoughts on Future Kind Super Plant Complex

We chose Future Kind Super Plant Complex as the best vegan ashwagandha supplement because it blends potent adaptogens with transparent vegan sourcing labelling. The formula aims to support mood, energy, and overall resilience.

Kayla gave this supplement a 5 out of 5 for first impressions. “I was immediately impressed by the sleek, eco-friendly packaging. The bottle is compact and lightweight, making it convenient for on the go use,” she said. She also loved that the label advertises the third-party testing. This gives the appearance of a quality brand focused on wellness and transparency. 

“The supplement comes with straightforward instructions,” Kayla noted, rating it a 5 out of 5 in this category. “The recommended dosage is two capsules per day with a meal, which is easy to remember and incorporate into a daily routine.”

 When it comes to capsule size and swallowability, Kayla gave this product a 5 out of 5. Each capsule contains a blend of nine clinically researched herbs, including Ashwagandha, Rhodiola, and Astralagus root. The capsules are of standard size, making them easy to swallow, Kayla described. The serving size is one capsule per day, which she found to be convenient and manageable.

“There was no aftertaste or digestive discomfort after taking the capsule, which is a testament to the quality of the product. I didn’t notice any changes in mood or negative effects from this product. If anything, I felt a little sleepy,” Kayla said.

Best Powder Ashwagandha Supplement: Moon Juice Ashwagandha

Our Thoughts on Moon Juice Ashwagandha 

Moon Juice Ashwagandha is our pick for the best powder form of ashwagandha because it offers a high-potency, full-spectrum root extract that allows you to dose and mix it to meet your preferences. We also like that it has an organic certification and no added fillers. 

Kayla rated her first impression of this product as a 3 out of 5. She loved the tiny glass bottle, giving the product a premium feel. “My only downside to this product is that it is a powder supplement, but it does not come with a scoop,” she said. “I don’t think it’s very transportable with it being glass and not providing that measuring scoop. I think this would be best used at home or you would need to bring a scoop with you everywhere to accurately measure it.” 

When dosing this product, Kayla said, “The instructions are a little unclear because it just says blend 1/4 teaspoon. Is it best in water? In coffee? Can you dry scoop it?” She rated the ease of understanding and following the instructions a 3 out of 5. That said, the serving size is small and incredibly easy to consume. 

Kayla rated the taste of this product a 3 out of 5. “The product says it has an earthy and bitter feel. I put mine in coffee and I could not taste it at all. I think possibly in water you could taste it, but I’m not an earthy taste fan so I’d rather find a base to mask the flavor,” Kayla said.

What is Ashwagandha?

Ashwagandha is a small shrub known in Ayurvedic medicine as an adaptogen—a substance thought to potentially help the body resist physical and mental stress. The root and leaves of ashwagandha contain bioactive compounds, most notably steroidal lactones called withanolides, which have shown broad biologic activity in laboratory and animal studies. Traditionally, ashwagandha has been used to support energy, enhance resilience, and improve overall health.

Current research on ashwagandha suggests it may help lower cortisol (the body’s main stress hormone), improve sleep quality, support cognitive function, and provide mild anxiolytic effects for stress and anxiety management. Many people take ashwagandha supplements hoping to reduce stress, boost mental performance, and promote restful sleep.

How We Tested and Selected the Best Ashwagandha Supplements

We tested and evaluated ashwagandha supplements and scored them on a scale of 1-5 for factors such as first impressions, easy-to-follow directions, swallowability, side effects, and value. Our testers evaluate the products based on their own individual experiences and preferences. We then review their testing feedback and data to share our findings and recommendations with you.

Formula

When selecting and testing ashwagandha supplements, we worked with a certified nutrition coach to ensure each formula meets the highest standards for efficacy and safety. Our evaluation process focuses on clinically supported dosages that reflect current research, seeking products that deliver the optimal amounts shown in peer-reviewed studies. Ingredient quality and transparency are top priorities, and we favored ashwagandha supplements made in GMP-certified facilities, with third-party testing, and free of unnecessary additives.

Taste and Texture

Flavor is a big part of our testing process. We ask our testers to provide feedback on the taste, aftertaste, and swallowability of the ashwagandha supplements.

Third-Party Testing

We selected ashwagandha supplements that have been verified through third-party testing for safety, purity, and label accuracy. This process also screens for harmful substances like heavy metals and pesticides.

For athletes, third-party testing is crucial to confirm there are no banned substances—products should be sport certified. Since the FDA does not regulate supplements, independent verification is essential for safety, accuracy, and consumer trust.

Value

When considering value, we place a higher value on brands that source their ingredients in America and have certifications, such as Informed Choice.

How to Find the Best Ashwagandha Supplements for You

Ashwagandha supplement needs vary based on your age, lifestyle, and any specific health goals you may have related to energy or mood support.

Consider these factors when choosing the best ashwagandha supplement for you.

Your Body’s Needs

When considering ashwagandha, it’s important to recognize that everyone’s health goals and needs are unique—especially among athletes and high-performing professionals. Some people try ashwagandha to target specific issues such as stress management, improved sleep, or athletic recovery.

While ashwagandha is safe for most people to take, it can interact with other medications or supplements. So, before you start taking ashwagandha regularly, we recommend speaking with a medical professional.

Flavors and Form

Most ashwagandha supplements come in capsule form, and sometimes as gummies. Occasionally it’s available in powder form. In any case, be sure to choose the form you enjoy taking, and if it’s a powder, look for a flavor that you enjoy.

Formula

Everyone has different dietary needs, so it’s worth checking the ingredient list before purchasing. Some formulas of ashwagandha include stimulants like caffeine, so be sure to check for your preference ahead of purchasing. If a supplement includes additional nutrients, compare them with your recommended daily values (RDVs) to avoid excess intake. 

Cost

Ashwagandha supplements are typically taken every day, and can be pricey, so you may want to consider your budget before purchasing. Cleaner formulations, meaning those without artificial sweeteners or additives, may cost more because of their higher quality and ingredient sourcing.

Third-Party Testing

Because the FDA does not regulate supplements, third-party testing provides independent verification of an ashwagandha supplement’s safety, purity, and label accuracy. This process protects against risks like mislabeling, contamination, or banned substances, giving you confidence in the products you choose. Independent testing is crucial for ensuring both product quality and safety.

Benefits of Ashwagandha

Like multivitamins, protein powders, and probiotics, ashwagandha supplements can offer an array of health benefits, potentially helping your mood and sleep. Here are some of those benefits:

• Stress and anxiety reduction: Regular use of ashwagandha may help lower cortisol levels and help relieve symptoms of stress and anxiety by calming the brain and allowing for more relaxation
• Sleep improvement: Ashwagandha may support better sleep quality and help with insomnia, making it easier to fall and stay asleep
• Enhanced energy and athletic performance: Studies suggest ashwagandha boosts energy levels, improves endurance, and can help with athletic recovery

How to Take Ashwagandha Supplements

Ashwagandha supplements come in various forms, such as capsules, powders, gummies, and more, allowing for flexibility based on your preferences. It is important to read and follow the instructions on the product label, as each form may have different concentrations and dosing recommendations to ensure safety and maximize its benefits. Talking with your doctor or other healthcare provider before starting an ashwagandha supplement can help you choose a form that suits your health and dietary goals best.

How Much Ashwagandha Should I Take?

There is not currently a standardized dose for ashwagandha, as the optimal amount can depend on individual needs and the specific supplement form. However, clinical research commonly tests doses ranging from 250 to 600 milligrams per day, with the most effective results often observed at 500–600 milligrams daily taken consistently for at least one to two months. 

What is the Best Time to Take Ashwagandha?

The best time to take ashwagandha is up to you and your health goals: it can be taken in the morning for energy and stress support, or in the evening to promote relaxation and better sleep. What matters the most is taking the supplement consistently and choosing a time that fits your daily routine. 

What to Avoid in Ashwagandha Supplements

While ashwagandha supplements offer health benefits, it’s important to be cautious and minimize health risks when starting a new supplement. Always check labels for quality, third-party testing, and avoid products with unnecessary additives or fillers. Do not use ashwagandha if you’re pregnant or breastfeeding. Avoid ashwagandha if you have autoimmune conditions, thyroid disorders, hormone-sensitive cancers, or liver disease, or if you take medications such as sedatives, immunosuppressants, or drugs for diabetes and blood pressure, due to possible interactions and adverse effects.
