Many people tend to shy away from fancy-sounding herbs that are common in traditional medicine around the world.

But they are also often surprised how effective many of them have proven in a placebo-controlled study.

Ashwagandha root is one such African herb that some dietitians and nutritionists recommend to boost testosterone levels.

And because we’ve increasingly seen it on the labels of testosterone boosting supplements, we wanted to show you our research to help you fully understand this herb.

Let’s take a closer look.

Quick Summary

  • Ashwagandha, a natural herb has been used for years to increase the testosterone levels of individuals struggling with low testosterone production.
  • It takes between eight to ten weeks for a person to start feeling the effects of the Ashwagandha herb.
  • Ashwagandha can also boost the performance of athletes, and offer a remedy for some erectile dysfunctions.

Can Ashwagandha Increase Testosterone?

Ashwagandha, a popular herb, has been studied for its potential role in boosting testosterone levels naturally, offering a potential natural solution for individuals seeking to optimize their hormone levels. Achieving optimal testosterone levels is particularly important for men over 30, which is when testosterone production drops by about 1% per year.

That can affect muscle mass, bone density, and stress hormone levels.

But very high testosterone levels can be equally disruptive. And with herbal supplements like Withania Somnifera, it’s important to assess whether they could result in very high T-levels.

Ashwagandha has shown promise in some studies as a potential supplement to increase testosterone levels, providing individuals with a natural option to support hormonal balance. Based on our research, this is not likely to be the case. It takes quite a while for effect to build up, and none of the trial research we read through showed any signs of excessive T-count.

You also have to keep in mind that most people who decide to take an herbal supplement like this will have a low starting point.

Even a significant increase from such a low point won’t mean that the effects of Ashwagandha extract are overall negative.

It’s also easy to regulate your intake and adjust it as your T-levels rise.

“Ashwagandha contains chemicals that might help calm the brain, reduce swelling, lower blood pressure, and alter the immune system.”


How Does It Work?

As mentioned above, Withania Somnifera is common in African alternative medicine, where it has been used for generations as a fertility enhancer to improve sperm quality and count. Ashwagandha has shown promise in some studies as a potential supplement to increase testosterone levels, providing individuals with a natural option to support hormonal balance.

I won’t go into the exact details of regulating reproductive hormone levels, but there are a few interesting facts worth mentioning.

One study found that it might be influencing the luteinizing hormone, which is directly linked to testosterone boosting supplements production [1]. And some interesting things happen in the body when testosterone heads back to a normal age-adjusted level.

For one, it should make it easier to maintain and grow muscle mass. Why else are some athletes tempted to take steroid hormones?

It also has a positive effect on resistance training, which further enhances general fitness levels, heart and sexual health.

It may also disrupt weight management issues where diet and exercise alone are not getting you past a plateau.

How Long Does It Take For Ashwagandha To Increase Testosterone?

Studies have shown that it takes about eight weeks for Withania Somnifera to start showing some effects [2].

The most significant improvements in hormonal and vitality effects could happen within a month.

But for performance during resistance training, it’ll likely take twice that long.

The reason is that Ashwagandha root extract helps slowly increase free T-levels, unlike medical replacement therapy which provides a sudden boost.

But such treatments should only be considered based on professional medical advice.

Does This Herb Have Any Side Effects?

Generally speaking, Ashwagandha root is safe for most people to take. But as with any root extract, there are some reported side effects that most often come down to a possible allergic reaction.

These are rare and can result in rashes as well as vomiting.

Some people have also reported that they felt cramps, bloating, and nausea, but in most cases, that stopped after just a few days.

One way to avoid this is to take a very small dose to start with and then gradually increase it over a few days.

Does Ashwagandha Supplementation Provide Other Health Benefits?

The great thing is that you don’t just have to consider the sexual health benefits of higher T-levels. There are reported benefits of oxidative stress during exercise and even erectile dysfunction.

Who doesn’t want to achieve some extra bedroom performance and stamina, right?

One interesting randomized, double-blind placebo-controlled trial showed that Withania Somnifera might also influence stress-related parameters [3].

That could make it a suitable herb for chronically stressed adults to reduce their cortisol levels.

Chronically stressed humans end up suffering from a lot of mental and physical issues, and the more you can deal with that at an early stage, the better the results will be for your health.

You can buy a standalone Ashwagandha supplement, but it might be worth considering a testosterone booster that has some other ingredients to help you with mild fatigue, increased body fat, muscle and bone mass, and even mental health issues.
