5 Best Testosterone Boosters [2021]: Reviews and Comparison

For most men, the decrease in testosterone production becomes a major concern as they age. The best method to combat this issue is to use a natural testosterone supplement. The problem here is that the supplement market is saturated with too many products. This review of the best testosterone boosters is here to help you choose the right one.

The drop in natural testosterone levels has both physical and mental consequences. Low testosterone reduces the existing muscle mass and makes it more difficult for muscles to grow. It also enables fat deposits to accumulate, especially around the waistline.

A drop in testosterone levels negatively affects motivation, competitiveness, sex drive, and libido.

Dietary changes and regular exercise are important to maintain testosterone levels. However, there are many natural supplements available that can provide even better results.

These are called testosterone boosters. In this article, we will answer the question, which is the best testosterone booster on the market today?  

The Quick Answer

All-natural testosterone boosters have the same goal, to increase testosterone production inside the body. They are usually made of similar ingredients. However, some fine differences can be important to consider when you are choosing the product that suits your particular needs best.

To help you make the right choice, we have put together a review of the best natural testosterone supplements in 5 different categories.   

Reviews of the 5 Best Testosterone Booster Supplements on the Market in 2021

This is a review of the best testosterone boosters in 5 different categories:

TestoGen – Best for Men with Naturally Low Testosterone Levels

Testosterone levels peak during puberty and naturally start to drop in the early ’20s. However, not all men produce the same amount of testosterone. So, some are more affected by the testosterone drop than others. TestoGen offers a solution to this problem.  

This is the best testosterone booster on the market for men with naturally low testosterone levels. Its comprehensive formula addresses all major symptoms of low testosterone levels. This includes:

  • Struggling to build muscle mass
  • Tiredness
  • The buildup of fat around the waist
  • Sexual performance
  • Lack of competitiveness

It is normal to experience a decrease in testosterone levels as you age. This does not mean that you have to say goodbye to your libido, muscles, and physical fitness. TestoGen helps you stay fit and preserve your “edge”.

The TestoGen formula contains D-Aspartic Acid, Magnesium, and Boron, among other ingredients. 

Research shows that regular intake of D-Aspartic acid significantly increases testosterone production over time. This increase could go over 45% in just a few weeks.

Apart from being an essential nutrient, magnesium also boosts testosterone production. Regular daily intake of magnesium (750mg) can enhance testosterone production by 26% in one month.

Boron is a naturally occurring mineral associated with increased testosterone levels. Different studies show that a small weekly intake of boron can cause as much as a 28% increase in free testosterone.   

Another important ingredient of TestoGen’s testosterone boosting formula is Nettle leaf extract. This is a unique characteristic of this product. Nettle leaf extract prevents testosterone from binding itself to the SHGB protein. In this way, it improves the circulation of testosterone inside the body.

Prime Male booster strengthens the muscles, including the heart. It promotes muscle growth and improves cognitive abilities as well as memory, especially in older men. 

Most importantly, Prime Male is the best for those men who are looking to improve their libido, endurance, energy, and sexual performance.

Scientific research has shown that higher testosterone levels work as a powerful aphrodisiac. Men with higher levels of testosterone are more assertive and more attractive to women. Prime Male booster’s formula makes the best use of this knowledge.

The formula of Testo Lab Pro is a well-balanced combination of ingredients that stimulate testosterone secretion and ingredients that block the production of unwanted hormones.

This product is available in the form of capsules. The capsules are made of fermented tapioca, a 100% natural material. This greatly increases the proper absorption of all ingredients that make up the Testo Lab Pro formula.
