Ashwagandha vs Kava (Can You Take Them Together?)

I may receive a commission for purchases made through product links on this page, but I always stand by my opinions and endorsements!

So, this is the year you want to get healthy.

That’s great!

There’s just one problem – you have 300 different supplements to choose from. So how do you know which one to take?

Well, in my Supplement Comparison Series, I take two supplements and put them against each other on benefits, side effects, price, and more. The goal isn’t to pick a “winner”, but to help you decide which one is right for you.

In this piece, we have Ashwagandha vs Kava.


Let’s go.

What is Ashwagandha?

ashwagandha plant

Ashwagandha (Withania Somnifera) is a herb native to India that’s been used for various health conditions for thousands of years. It belongs to the Solanaceae family of plants which includes popular vegetables like eggplants and potatoes.

It’s known for its ability to promote feelings of strength, calmness, and wellbeing in people.

In the Sanskrit language, Ashwagandha roughly translates to the smell of a horse, suggesting it can give you the strength of a stallion.

(The root of Ashwagandha supposedly smells like horse sweat. A fair trade-off for giving you the strength of a stallion in my opinion!)

What is Kava?

Kava (Piper Methysticum) is a plant native to Melanesia, Polynesia, and Micronesia. In these regions, people have been using Kava at social ceremonies for thousands of years.

And like Ashwagandha, Kava belongs to the Solanaceae family of plants.

Today, Kava is used across the globe for its calming and euphoric effects.


Benefits of Ashwagandha

Ashwagandha may help relieve anxiety

Wanna know a shocking fact?

More than 40 million US adults suffer from anxiety and related disorders.

This makes anxiety the most common mental ailment in America.

Well according to research, Ashwagandha may be useful for those suffering from anxiety.

In one study, the subjects took either 600mg of Ashwagandha or a placebo each day for 2 months.

According to the results, the Ashwagandha group had a bigger reduction in scores on the stress test than the placebo group.

Another study compared the anxiety levels of people taking either Ashwagandha or a placebo each day for 6 weeks.

By the end of the 6 weeks, 88% of the Ashwagandha takers had less anxiety.

Ashwagandha may help boost testosterone levels

Many people have lower than ideal testosterone levels nowadays.

There are various reasons for this including poor diets, lack of exercise, and poor sleep hygiene.

But low testosterone levels are nothing to laugh about – they may even contribute to depression in aging men. (Source)

And this is where Ashwagandha may be handy.

A study of 75 infertile men found that Ashwagandha supplementation increased Seminal testosterone levels.

Ashwagandha may help increase lean mass and strength

Although Ashwagandha is rarely talked about in the bodybuilding community, research shows it may help those wanting to get bigger and stronger.

A study of 57 subjects investigated the effects of Ashwagandha on muscle size and strength.

Each day of the study, some people took 600mg of Ashwagandha and the others took a placebo.

The results showed that the Ashwagandha group had bigger increases in lean mass, strength, fat loss, and testosterone levels than the placebo group.

Ashwagandha may help lower blood sugar levels

According to research, Ashwagandha may help lower blood sugar levels.

In one study, 12 participants took Ashwagandha and their blood sugar levels were monitored.

After taking Ashwagandha for a month, their blood sugar levels were lowered by amounts comparable to a blood sugar lowering drug.

Benefits of Kava

Kava may help boost mental function

Kava is widely used for its brain-boosting properties.

And for good reason too.

One study showed that a single 300mg dose of Kava improved visual attention and short term memory.

In another study, 12 people took either Kava or oxazepam before a word recognition task.

According to the results, the Kava takers performed significantly better at the task than the oxazepam takers.

Kava may help improve sleep

Many people take Kava as a natural sleep aid.

In one study, 24 people with insomnia took 120mg of Kava each day for 6 weeks.

According to the results, the Kava significantly improved their insomnia by lowering their stress.

In another study, 61 people took either 200mg of Kava extract or a placebo each day for 4 weeks.

The results showed that the Kava group had significantly better sleep than the placebo group.

Interestingly, they also reported less anxiety.

Kava may help relieve anxiety

Like Ashwagandha, Kava may help reduce anxiety.

In one study, 101 people with anxiety took either Kava or a placebo for 25 weeks.

The results showed that the Kava takers had significantly improved anxiety after 8 weeks.

Also, a review of 11 studies found that Kava significantly reduced anxiety when compared to a placebo.

Kava Kalm Micronized Kava Powder is the bee’s knees.

What I like about it

The fact that it’s powdered means you can mix and match the dosage to meet your individual needs.
