The Best Testosterone Booster: Which Supplements Work?

In today's fitness and health world, the pursuit of optimal performance is a constant. One of the most debated topics in this arena is testosterone, the primary male sex hormone that plays a crucial role in muscle growth, fat loss and overall health. With the growing interest in natural methods of increasing testosterone levels, numerous supplements have come onto the market claiming to increase testosterone levels best testosterone booster to be. But which of these are really effective? And which ones are safe for consumption?


DHEA (Dehydroepiandrosterone)

Research design

DHEA is one of the most studied natural testosterone boosters. It is a precursor hormone, meaning it can be converted into both testosterone and estrogen in the body. Most studies on DHEA have focused on older adults, as the natural production of this hormone decreases with age.

In a typical study of DHEA supplementation, participants are given a daily dose of DHEA for a period of time, while a control group is given a placebo. Testosterone levels are then measured to assess any changes.


Research results

The results of DHEA studies are mixed. Some studies have shown moderate increases in testosterone levels in men after DHEA supplementation, especially in older adults. However, other studies have found no significant difference between the DHEA group and the placebo group.


Conflicting Research Results

The variability in study results may be due to differences in dosage, duration of supplementation, and the specific populations being studied. For example, some studies suggest that DHEA may be more effective at increasing testosterone in older men compared to younger men.


Side effects of DHEA

Although DHEA is often praised as a best testosterone booster, it is not without potential side effects. Some of the most common side effects include acne, hair loss, high blood pressure, and mood swings. Additionally, women who take DHEA supplements may experience symptoms such as deepening of the voice, unwanted hair growth, and irregular periods.


Status in the European Union and WADA

The sale of DHEA supplements is banned in many countries of the European Union due to safety concerns and possible abuse. As for sports, DHEA is on the World Anti-Doping Agency's (WADA) Prohibited Substances List, which means that athletes covered by WADA regulations are at risk of sanctions if they are caught using DHEA.


D-Aspartic Acid (DAA)

Research design

D-Aspartic Acid is another supplement often promoted as the best testosterone booster. It is an amino acid that plays a role in the production and release of hormones in the body. Most studies of DAA have examined its effects on testosterone levels over a short period of time (usually 6-12 days).

In these studies, participants are given a daily dose of DAA, and their testosterone levels are measured at the beginning and end of the study period.


Research results

Studies have shown that DAA supplementation can increase testosterone levels within days. However, this increase appears to be temporary, with levels returning to baseline after about a week of supplementation. This suggests that while DAA may work temporarily as a testosterone booster, it may not be effective for long-term use.


Conflicting Research Results

While some studies have shown a significant increase in testosterone levels following DAA supplementation, other studies have not observed such an increase. These inconsistencies may be due to differences in DAA dosage, study duration, and specific demographics of participants.


Side Effects of D-Aspartic Acid

D-Aspartic Acid is generally considered safe for short-term use. However, some users have reported side effects such as mood swings, nervousness and anxiety. Long-term supplementation with DAA without medical supervision is not recommended, mainly due to the lack of research on its long-term effects.


Status in the European Union and WADA

D-Aspartic Acid is freely available in most European Union countries and is not considered a banned substance by WADA. However, as always, athletes are advised to check their national and sport-specific doping regulations before taking any new supplement.


Taurine


Research design

Taurine, an amino acid that occurs naturally in the body, is often promoted for its energy-boosting properties. Although it is not directly considered a best testosterone booster, there are studies that have examined the effects of taurine on testosterone levels.

In these studies, taurine is administered to participants, after which their testosterone levels are measured to assess any changes.


Research results

Results regarding taurine and testosterone are mixed. Some studies suggest that taurine may increase testosterone levels by reducing oxidative stress in the testicles. However, other studies have not observed significant changes in testosterone levels after taurine supplementation.


Conflicting Research Results

As with other supplements, the results of taurine studies are inconsistent. The variability in results may be due to several factors such as dosage, duration of supplementation, and the specific demographics of the participants.


Side effects of Taurine

Taurine is generally considered safe and is commonly found in energy drinks and pre-workout supplements. However, excessive consumption can lead to side effects such as high blood pressure, headaches and dizziness. It is important not to exceed the recommended dosage and always seek medical advice before starting to take any new supplement.


Status in the European Union and WADA

Taurine is freely available in the European Union and is not on WADA's list of banned substances. Athletes and fitness enthusiasts can use it without any worries, but it is always advisable to check the specific rules of your sports association.


shilajit

Research design

Shilajit, a resinous substance found in the rocks of the Himalayas, has been used in traditional Ayurvedic medicine for a variety of health benefits. Studies have been conducted to investigate the effects of Shilajit on testosterone levels.


In these studies, participants are given a certain dose of Shilajit for a specific period of time, after which their testosterone levels are measured.


Research results

Studies have reported that Shilajit can increase testosterone levels in healthy volunteers after regular supplementation. The increase was significant compared to the control group that received a placebo.


Conflicting Research Results

While most studies have shown positive results, there are a few studies that have not observed a significant change in testosterone levels after Shilajit supplementation. These differences may be due to variations in the quality of Shilajit, dosages and the length of the study.


Side Effects of Shilajit

Shilajit is generally considered safe at recommended dosages. However, some people may experience side effects such as dizziness, nausea and increased heart rate. It is essential to start with a low dose to see how your body responds and gradually increase the dose if necessary.


Status in the European Union and WADA

Shilajit is permitted in many European Union countries, but quality and purity may vary between different brands and products. It is not on WADA's banned substances list, but athletes should always exercise caution and ensure they are using a pure product with no added banned substances.


turkesterone

Research design

Turkesterone is an ecdysteroid, a group of naturally occurring steroids found in some plants and insects. Studies have been conducted to investigate the anabolic effects of Turkesterone and its potential impact on testosterone levels.

In these studies, participants are given a certain dose of Turkesterone for a specific period of time, after which their testosterone levels and muscle mass are measured.


Research results

The results of studies on Turkesterone are promising. Although it does not directly increase testosterone levels, researchers say it does have anabolic effects similar to those of testosterone. According to researchers, this means that it can help build muscle mass and improve sports performance.


Conflicting Research Results

While many studies have shown positive results, there are a few studies that have not observed significant benefits from Turkesterone supplementation. These differences may be due to variations in dosages, length of study, and specific demographics of participants.


Side effects of Turkesterone

Turkesterone is generally considered safe, but there is limited information on its possible side effects in humans. Some animal studies have shown that high doses of Turkesterone can affect the liver, so it is essential to stay within recommended doses and have regular medical checkups when taking this supplement.


Status in the European Union and WADA

Turkesterone is permitted in many countries in the European Union. It is not on WADA's banned substance list, but as always athletes are advised to check their national and sport-specific anti-doping rules before taking any new supplement.

NB! Very many fake Turkesterone 10% on the market. 99% of the Turkesterone 10% is not real and is therefore not an extract of the Ajuga Turkestanica plant. This plant, from which Turkesterone is made, only grows in Uzbekistan. Almost all fake Turkesterone is imported from China. Unfortunately, there is no good control over this.


Beta Ecdysterone

Research design

Beta-Ecdysterone, like Turkesterone, is an ecdysteroid. Studies have been conducted to investigate the effects of Beta-Ecdysterone on muscle growth and testosterone levels. In these studies, participants are given a certain dose of Beta-Ecdysterone for a specific period of time, after which their testosterone levels and muscle mass are measured.


Research results

Studies have shown that Beta-Ecdysterone can stimulate protein synthesis in muscle cells, which can lead to an increase in muscle mass. However, it does not seem to have a direct effect on testosterone levels. The anabolic effects are similar to those of certain anabolic steroids, but without the side effects often associated with steroid use.


Conflicting Research Results

While many studies have shown positive results, there are some studies that have not observed significant benefits from Beta-Ecdysterone supplementation. These differences may be due to variations in dosages, duration of the study, and the specific demographics of the participants.


Side Effects of Beta-Ecdysterone

Beta-Ecdysterone is generally considered safe, but as with other supplements it is important to use caution. There are reports of mild stomach upset in some users. Because there is limited data on the long-term effects of Beta-Ecdysterone, it is advisable to seek regular medical advice when taking this supplement.


Status in the European Union and WADA

Beta-Ecdysterone is permitted in many countries of the European Union. Although it is not on WADA's list of banned substances, there has been some discussion about its possible inclusion due to its anabolic effects. Athletes should therefore be careful and check the regulations regularly.


Tongkat Ali

Research design

Tongkat Ali, also known as Eurycoma longifolia, is a herb from Southeast Asia traditionally used to improve male fertility and libido. Studies have examined the effects of Tongkat Ali on testosterone levels and sexual health.


In these studies, participants are given a specific dose of Tongkat Ali over a specific period of time, after which their testosterone levels and other related parameters are measured.


Research results

Most studies have shown that tongkat ali can increase testosterone levels in men, especially those with low levels. In addition, many users have reported improvements in libido and sexual performance.


Conflicting Research Results

While many studies have shown positive results, there are a few studies that have not observed significant changes in testosterone levels after Tongkat Ali supplementation. These differences may be due to variations in dosages, the quality of the supplement, and the specific demographics of the participants.


Side effects of Tongkat Ali

While Tongkat Ali is generally considered safe, some users have reported side effects such as insomnia, increased heart rate, and restlessness. It is essential to start with a low dose to see how your body responds and gradually increase the dose if necessary.


Status in the European Union and WADA

The sale of tongkat ali is banned in some countries of the European Union due to safety concerns. It is not on WADA's List of Prohibited Substances, but athletes should always exercise caution and ensure they are using a pure product with no added Prohibited Substances.


chrysin

Research design

Chrysin is a flavonoid found in bee propolis, honey and some plants. It is often promoted as a best testosterone booster due to its purported ability to block the conversion of testosterone to estrogen. Studies have examined the effects of Chrysin on testosterone levels and estrogen levels.

In these studies, participants are given a certain dose of Chrysin for a specific period of time, after which their hormone levels are measured.


Research results

Most studies have shown that Chrysin can reduce estrogen levels in animals, but there is limited evidence for a similar effect in humans. As for testosterone, results are mixed, with some studies showing a slight increase in testosterone levels and others noting any significant effect.


Conflicting Research Results

While some studies have shown positive results, there are studies that have not observed significant changes in testosterone or estrogen levels after Chrysin supplementation. These differences may be due to variations in dosages, the quality of the supplement, and the specific demographics of the participants.


Side effects of Chrysin

Chrysin is generally considered safe at recommended dosages. However, some users have reported side effects such as headaches, dizziness and upset stomach. It is important not to exceed the recommended dosage and always seek medical advice before starting to take a new supplement.

In these studies, participants are given a certain dose of Fadogia Agrestis for a specific period of time, after which their testosterone levels are measured.


Research results

Most studies have shown that Fadogia Agrestis can increase testosterone levels in animals. However, limited research has been done in humans, making it difficult to draw definitive conclusions about effectiveness in humans.


Conflicting Research Results

Due to the limited research on Fadogia Agrestis in humans, results are inconsistent. More research is needed to fully understand the effects of this herb on testosterone levels in humans.


Side Effects of Fadogia Agrestis

Although Fadogia Agrestis has been used traditionally in certain cultures with no reported serious side effects, there is limited scientific information on the safety of this herb for long-term use. Some animal studies have shown that high doses can lead to an enlarged prostate. Therefore, it is essential to be careful and start with a low dose to see how your body reacts.


Status in the European Union and WADA

The status of Fadogia Agrestis varies across the European Union, with some countries restricting its sale due to the lack of extensive research. It is not on WADA's list of banned substances, but athletes should always exercise caution and ensure they are using a pure product.
