8 Best Ashwagandha Supplements (2023) Reviewed and Compared

Never miss a glorious update - click here!

Ashwagandha, an ancient Indian herb, that has become increasingly popular as a supplement in testosterone boosters and as a standalone supplement.

You may also see it listed as Withania somnifera, its formal Latin name. For those of us who don’t speak Latin (like me) we’ll stick with the former.

In this article, we cover everything you need to know about this healing shrub and the best ashwagandha supplements on the market.

What is Ashwagandha?

Ashwagandha is an herb native to India, and it has been used for medicinal purposes for centuries. It’s most commonly used for treating stress but has various potential benefits, from treating fertility to increasing muscle strength.

It can be consumed in powder or capsule form, or it can be ingested as tea. However, research suggests that you need to take ashwagandha for several months before seeing its effects. Dosing recommendations for ashwagandha can vary from 250 to 1000 mg.

While ashwagandha can be an effective supplement, it’s not for everyone. Pregnant women should not consume ashwagandha because it can cause complications, including miscarriage.

What Are The Benefits of Ashwagandha Supplements?

An ashwagandha supplement has various potential health benefits, including enhancing athletic ability, supporting male fertility, and relieving stress.

Ashwagandha might enhance athletic performance

A review of five studies discovered that participants who took ashwagandha experienced an improvement in VO2 max, short for maximum oxygen consumption, which is important for optimal cardiovascular health.

Another study showed that taking 600 mg of ashwagandha every day might improve muscle strength.

This is likely as a downstream effect of supporting testosterone production. 

Ashwagandha may help reduce stress.

Ashwagandha is considered an adaptogen, which is a plant that helps the body respond to stressors. Adaptogen consumption has been linked to reduced anxiety levels.

One study showed, for example, that taking ashwagandha long-term can help lower cortisol levels and reduce stress.

A different study had similar results, showing that taking 240 mg of ashwagandha every day could reduce anxiety levels. In fact, it’s a key ingredient in many supplements designed to help manage cortisol

Ashwagandha may support cognitive function.

While not a classic “nootropic” ingredient like l-tyrosine or choline, there are some claims that ashwagandha can slow brain decline. All of this research, though, is on older populations and those with some kind of cognitive impairment. Whether it supports cognition in healthy adults, we dont’ know. 

Ashwagandha may improve testosterone levels and support male fertility.

One study showed that taking ashwagandha helped men aged 40 to 70 increase testosterone levels. Other studies demonstrated that ashwagandha was linked to increased sperm concentration.

While research on the benefits of ashwagandha has been promising so far, more research is needed.

Price: from $19.

A few elements make Goli an easy top choice

Patented KSM-66® Form

What separates Goli, as well as a few of our top choices, is that they use a patented form of ashwagandha, KSM-66®.

This form has a specific extraction process that results in a full-spectrum ashwagandha extract. By “full-spectrum,” that means it uses all of the parts of the herb, without overrepresenting one particular component.

KSM-66 has the highest percentage of naturally-occurring withanolides of root-only extracts available on the market today, with more than 5% concentrations.

Many ashwagandha products don’t even reveal the concentration. Withanolides are naturally-occuring compounds in ashwagandha (and lots of other stuff) that have a host of health and pharmacological applications. The withanolides in ashwagandha have specific research, and in general we want more of them.

KSM-66® ashwagandha seems to be more bioavailable, and it’s the form that specifically has the most solid research behind it.

Luckily, it’s not more expensive, either, so in our estimate, choosing an ashwagandha product that uses KSM-66® is a no-brainer.

Added Vitamin D

To further support your immune system, Goji added vitamin D to their blend. 

No Extra Anything

Finally, and perhaps most importantly, Goji maintains a commitment to putting only the best stuff in, and leaving everything else out. 

It’s vegan, kosher, non-GMO, gluten-free, and even use a pectin (fruit peel) gummy instead of the typical gelatin gummy.

Goli also has some of the best customer service out there, and it comes with a 30-day money-back guarantee.

For all of these reasons, Goli Ashwa Gummies is our top pick.
