What is Shilajit?

Shilajit is a mix of minerals that takes a similar form to tar, it is found in the Himalayas and there is some debate about where it originates.

Some scientists say that it is geological while others say that it is biological and comes from plants. It has been used for hundreds of years in traditional medicine used in India (called Ayurveda).

Whilst it has been used in India for centuries, it is relatively new to the Western world and as such there is a serious lack of scientific analysis on it.

What is the research is saying?

That being said, there have been a few studies done. In 2003 a study by Sharma et al found that Shilajit improved the blood profile of subjects after 45 days of supplementation [1].

This means that it may have a positive effect on Cholesterol and blood lipid levels, lowering your risk of high blood pressure, heart attacks or strokes.

This is good news for a lot of people, but the main reason why the fitness world has got excited about Shilijat is the potential testosterone boosting effect that it may have.

Having low testosterone is not something you want, if you’re looking to boost natural testosterone levels be sure to do it with the right ingredients.

In 2010 there was a study by Biswas et al that looked into the effect of Shilijat on infertile men, the study lasted 90 days and involved 60 men [2]. The study found that taking 200mg of Shilajit led to a 23.5% increase in serum testosterone.

Now men who are infertile tend to have a very low testosterone level, meaning that this huge increase in testosterone may have just been bringing the level up to that of a regular guy, but still these are some pretty impressive results.

Recent Study Findings

There was a more recent study in 2016 by Pandit et al [3]. The study was performed on healthy volunteers who were aged between 45 and 55 years old. In this study they took 250mg of Shilajit twice per day for 90 days. The study found that the treatment led to a significant increase in total testosterone levels, and free testosterone levels.

This seems pretty conclusive proof that Shilajit increases testosterone levels, but it’s important to add the right exercises to your workout for optimal results however, there are a couple of things to consider.

Firstly this study was done on men between 45 and 55 years old, when testosterone levels will have naturally begun to drop. Secondly, the study was funded by Natreon inc. Which are a company that sells Shilajit, meaning there may have been a bias.

The truth is that many studies are funded by interested parties, and this does not mean that the results should be discounted. Who is going to a fund a study into Shilajit other than somebody who sells it?

At the end of the day there have been two studies that looked into the effect of Shilajit on testosterone levels, and both studies found that Shilajit had a significant effect.

Final Thoughts

If you are suffering from low testosterone, or have just come out of a period of low calorie dieting (which can lower testosterone) then taking Shilajit, along with other top natural testosterone boosting ingredients should have a positive effect.

If you already have high testosterone levels, then it may not work – but as yet there is no solidifying evidence that it does or not. Finally, it might be a good idea to consider the right estrogen blocking supplement in combination with high testosterone because when test levels rise, so does your estrogen and this can have some negative affects on the body.
