This ancient medicine can be used to improve a number of our cognitive functions and productivity. That’s why we want to tell you everything you need to know before you guy out and purchase.

First of All, what is Ashwagandha?

Ashwagandha (Withania somnifera) is an evergreen shrub that grows in Asia and Africa. It is commonly used for stress and is known as an “adaptogen” due to its ability to help the body cope with physical and mental stress. Ashwagandha has been used for centuries in Ayurvedic medicine, a traditional Indian form of healing.

The root of the Ashwagandha plant is most commonly used for medicinal purposes, although some people also use the leaves or berries. The root contains several active compounds, including withanolides, which are believed to be responsible for many of its health benefits. Studies have shown that Ashwagandha can reduce levels of cortisol, a hormone released in response to stress, as well as improve cognitive function and reduce symptoms of depression and anxiety (1).

In addition to its medicinal uses, ashwagandha has also been used in traditional Indian cooking for centuries. The root can be dried and powdered or made into a tea or extract. It has a slightly bitter taste but can be added to smoothies or other beverages for a nutritional boost.

Overall, Ashwagandha is a powerful adaptogenic herb with numerous potential health benefits. Its long history of use in Ayurvedic medicine makes it one of the most studied herbs today, with more research being conducted on its potential therapeutic effects every day.

Why Supplement with Ashwagandha?

As you probably already know, a supplement is a capsule, tablet, or powder made up of natural ingredients that benefit our bodies. An Ashwagandha supplement isn’t any different.

Commonly coming in the shape of a white capsule or powder, Ashwagandha supplements contain the best parts of the plant to support cognitive health, manage our mood and stress levels, promote a healthy body weight, aid muscle recovery, and improve brain function. They can also be used in the treatment of sleeping disorders like insomnia.

Most Ashwagandha supplements are produced using the roots and leaves of the plant. The chemical compounds found within these parts of the plant provide the best benefits. The chemical compounds in the roots contain steroidal lactones of withanolides and withaferins, alkaloids, and saponins. The leaves also contain withanolide-R and withasomniferin-A.

How Do these Ashwagandha Supplements Work?

Research suggests that Ashwagandha creates an anti-stress effect through the suppression of glutamate neuron excitations and corticosterone signaling (2).

It is also believed to increase serotonin levels in the brain and enhance the GABA receptors (3). This alters our mood, making us feel more positive and focused. The enhancement of GABA receptors also helps to boost dopamine levels in the brain, which increases our ability to focus, feel pleasure, and concentrate.

The Benefits of These Supplements

We have already mentioned a few benefits of Ashwagandha supplements, but now we will look at them in more depth.

Reduces Anxiety, Stress, and Depression

According to Speers, Alex B et al., Ashwagandha was shown to impact those suffering from anxiety and stress significantly.

The supplement reduced the build-up of cortisol (stress hormones) in those with chronic stress conditions.

Increased Muscle Mass and Strength

A comprehensive systematic review and Bayesian meta-analysis concluded that Ashwagandha supplementation could be effectively used to improve various physical fitness parameters in healthy men and female (4). The researchers found that subjects who consumed Ashwagandha had higher strength/power levels compared to those in the placebo group.

It was also observed that there is a significant improvement in cardiorespiratory fitness and recovery time in those supplemented with Ashwagandha compared to placebo users. Furthermore, there is a high probability (>95%) that consumption of the aqueous Ashwagandha extract leads to at least a small effect size on physical performance, according to Bonilla, Diego A et al.

Improved Brain Function and Memory

Studies show that brain function and memory can be improved by taking Ashwagandha supplements. The supplements increase reaction time and also reduce the chance of oxidative damage. This reduction of oxidative damage can protect us against memory loss and assist in keeping our brains functioning well.

By protecting and improving our brains we can focus for longer and take in more information. This will help us be more productive at work and ace our final exams.

Reduces Blood Sugar Levels

Ashwagandha influences your body’s insulin secretion, modifying your blood composition. This helps lower blood sugar levels whether you have diabetes or not. In fact, some research has concluded that these supplements can be as effective as some diabetes-specific medicines (5).

Boosts Your Immune System

Feeling stressed can have a big negative impact on your immune system. By reducing stress through the use of Ashwagandha supplements you give your immune system a chance to catch up and repair itself. As a result, you will feel more positive and alive again.

Side Effect From Taking Ashwagandha Supplements

Ashwagandha has been through many clinical trials to guarantee it is safe to consume. However, like many other supplements, some mild side effects are worth knowing about.

It is worth noting that most people don’t experience any of these side effects, but if you unfortunately do, it is a good idea to stop taking the supplements before getting in touch with your doctor. They will then advise you on the best thing to do.

When taking any new supplements, check with your doctor first anyway. Taking the supplements might interfere with the drugs you already take. If this is the case, your doctor can tell you to stay away from them.


A small number of people have reported experiencing headaches after using Ashwagandha supplements. This isn’t uncommon when starting to take a new supplement, and it shouldn’t last long. If you do experience a persistent headache, though, it could lead to some nasty migraines, so make sure you let your doctor know.

Stomach Aches

You might experience an upset stomach when taking these supplements. This could cause you some discomfort or result in a spell of diarrhea. People who have experienced this all stated that the feeling didn’t last too long, and they soon felt great again.


Some individuals have been known to feel tired after taking Ashwagandha. This has been linked to the reduction of blood pressure. Low blood pressure is good, but when it gets too low, we can start to feel tired. If you don’t need to lower your blood pressure but still take one of these supplements, you could experience a tired feeling.
