Best Testosterone Booster Supplements of 2021


Testosterone is the hormone that plays a vital role in a man’s health. It aids in maintaining muscle mass, helps with sex drive, and also supports bone density.

Testosterone levels vary with age. Production of the hormone will be at its peak during early adulthood. The levels start to dwindle with each passing year.

When the body is not producing enough testosterone, it is referred to as ‘low T’. But we are not necessarily talking about really low levels. Here, we are focused on boosting levels as age advances, so you feel confident, perform better in bed, and don’t give up on the goal for a ripped look.

A man over 40 years old will definitely have significantly lower T-levels when compared to one in his ’20s. As you may know, there are numerous products in the market that promise to enhance levels. Navigating through them to pick the right one is a challenge.

Also, not all products are transparent about contents and side effects. Here, we have put together a list of the top 5 testosterone boosters that we recommend.

Also included are the details of the supplements, that encompasses ingredients, advantages, dosage, and side effects. An important point worth mentioning is that these 5 testosterone boosters are made using natural ingredients.

Top 5 Natural Testosterone Boosters:

  1. TestoPrime – Strongest T-Booster
  2. Testogen Best for Men Over 40
  3. Testo-Max Best for Building Muscle
  4. Prime Male Best Customer Service
  5. TestRX – Best for Libido

Why Should You Consider a Testosterone Booster?

As mentioned above, levels of the hormone drop as age advances. Between the ages of 20 and 25 is when the levels are at their highest.

As you enter the mid-thirties, your hormone level gradually starts to decrease. Lowering of testosterone levels with age is a normal process. Nevertheless, what transpires is that the body’s various functions that are supported by the hormone are affected.

You will notice that cutting down weight becomes difficult despite working out; sexual performance is not as good as it used to be earlier, and muscle development is impacted. Also, muscle growth slows down substantially.

But you need not worry just yet. There are natural solutions, in the form of dietary supplements, that are available in the market. Testosterone boosters that are made from natural elements should be given a chance as numerous people have benefited from these supplements without any adverse side effects.

Bare in mind that these supplements are not designed to enhance levels of someone in their 60s to match with their younger self in their 20s. They are created to boost levels, so the body performs all the required tasks that are dependent on the hormone level with relatively better outcomes.

Best Testosterone Boosters: Review of the Top 5

Sifting through the many boosters available in the market is an arduous task. Narrowing it down to the top 5, all the more difficult. We invested a lot of time to find the right supplements.

Testosterone Booster Ingredients (Natural Sources)

Let’s understand the working of testosterone before we dive into the ingredients that contribute towards boosting the hormone levels.

Testosterone is essential or vital for various functions in the body. It serves more than one purpose.

Brands generally have an approach wherein they focus on a particular issue and find ingredients that are best suited for that specific problem.

Elaborating on the aforementioned, one particular testosterone booster facilitates muscle building while the other helps burn fat and the third one focuses on enabling a better quality of sleep.

Though all boosters, in general, increase the hormone levels and address all issues up to a certain percentage, they are designed predominantly to address one specific concern.

The most popular ingredient is ZMA, which includes vitamin B6, zinc, and magnesium. There are studies that back the role these ingredients play in enhancing testosterone levels. Furthermore, ZMA is known to improve sleep quality, enabling the body to streamline itself naturally.

Some other ingredients used in natural boosters include fenugreek, long jack, D-aspartic acid, and many more.

While each ingredient mainly focuses on a single issue, it adds nutrients to the body, which help with maintaining health in general, such as antioxidants and some other nutrients that limit the unfavorable hormones from increasing.

Signs That Point to Low Testosterone Levels

Any lay man, and not necessarily a medic, can assess if testosterone hormone levels are low for themselves. Of course, knowing how low requires medical help.

Below are symptoms that indicate that levels may be low, and your body require attention:

Decrease in Muscle Mass

Muscle mass tends to lessen with age due to dwindling testosterone levels in the body. If you feel your muscle mass is decreasing at a concerning pace, despite exercising and eating well, it is a clear indication of low hormone levels.

Accumulation of Fat

If you accumulate body fat despite working out and sticking to a healthy diet, it may be due to low T levels.

Additionally, gynecomastia is a condition when breast tissue in men seems enlarged due to an imbalance in hormone levels. Testosterone drops so low that the ratio with respect to the reproductive hormone, estrogen gets disrupted.

Frequent Changes in Mood

If for no reason, you tend to feel depressed and don’t seem to suffer from any infection or the flu, then it is possible that the low T levels are causing the mood swings. When values slump drastically, you may find it hard to focus and are almost always irritable.

Decreased Libido

Sex drive decreases as age advances. Nevertheless, if there is a sudden lack of interest in sex, then the testosterone level plummeting could be the cause.

Sustaining Erections Becomes A Challenge

When testosterone levels are low, the brain does not receive the signal to produce nitric oxide, which is required to enable a chain reaction that facilitates an erection. So, if you experience erection issues, it is possible, testosterone is low in the body.

How Do Testosterone Boosters Work?

Testosterone boosters are designed to address a particular issue. They are created accordingly by picking specific ingredients and combining them in the required proportion suitable for that issue.

1. Freeing up Testosterone, so it is Available

The body has enough testosterone. The low T problem stems from the fact that a substantial percentage is bound by the protein globulin. Thus, it is unavailable when required. Studies suggest that nearly 60 percent of the entire amount is available for use.

Some of the testosterone boosters function by limiting the globulin production. The ingredients are chosen for that purpose. Thus, free testosterone levels are increased in the body through the use of this booster.

2. Lowering Prolactin and Estrogen levels

The hormones prolactin and estrogen are found in huge quantities in women when compared to men. But in certain scenarios, the levels rise even in a man’s body, which is undesirable. The consequence is the lowering of testosterone levels.

The rise is attributed to an enzyme, aromatase, that contributes to enhanced estrogen production. Some of the testosterone boosters are produced with ingredients that limit aromatase production. Thus, estrogen is limited, and a sufficient amount of testosterone gets released using this booster.

3. Serve as Dietary Supplements for Nourishment

The brain and the endocrine glands together generate sufficient testosterone naturally. But the organs need the right nutrients from food. However, it appears that diets these days are missing some essential ingredients that aid in testosterone manufacturing.

Testosterone boosters of the highest quality ensure that the body receives all the nutrients to enable testosterone production.

Benefits of Testosterone Boosters

The numerous issues that emerge from low levels of testosterone that we have seen in earlier sections can be addressed, either entirely or at least to a certain degree, with testosterone boosters.

Better Blood Circulation

Testosterone helps with red blood cell production. To make sure muscles get the required amount of oxygen, red blood cells are essential in good quantities.

Studies have shown that men with low testosterone are prone to heart ailments. Thus, testosterone is needed for the appropriate functioning of the cardiovascular system.

Improved Bone Density

Bone density is negatively impacted by dwindling testosterone levels. It can cause osteoporosis and also makes you susceptible to injuries. That is the primary reason athletes prefer to take testosterone boosters, so athletic performance is not affected by lowered bone density.

Helps Build Lean Muscle Mass

For a ripped look, people opt for testosterone boosters. It helps burn fat and aids in gradually building a lean muscle mass. Bodybuilders are inclined to take testosterone boosters specifically for that reason.

Improved Libido

If you want help with sex drive, try testosterone boosters. It is very likely that you will not be disappointed. Also, if you have issues sustaining an erection for a considerable amount of time, you must consider the boosters. A large number of people have benefitted.

Better Mood

Constant irritability and a depressed feeling could all be due to low T levels. Testosterone boosters can assist with fixing mood swings and enable you to feel energetic. Several studies have shown that a good amount of testosterone leads to more energy, less fatigue, and also less mood swings.

Side Effects of Testosterone Boosters

Since all of the products listed above are made from natural ingredients, the risk of side effects is generally very low. Adhering to dosage recommendations by the manufacturer will ensure that you do not experience any adverse side effects. Nevertheless, every person’s body is not alike, and some do experience mild side effects, which will not last long and are not concerning.

Talk to a doctor before committing to a testosterone booster supplement if you have other health issues and are on medication.

Dosing Suggestions for Best Results

The manufacturer launches a product with guidelines about the dosage, something the company releases after research and testing. Adhering to it is the right thing to do.

Less dose will not yield results, and overdosing could be harmful.

General guidelines for testosterone capsules are as below:

  • For Men who are 50+, 4-5 pills each day
  • For Men 40 years and older, 3-4 pills in a day
  • When it comes to bodybuilding, 4 pills maximum in one day, preferably before breakfast.


Testosterone levels drop with age. Between 20 and 25 years, the levels are at the peak. Eventually, once you touch 30, the levels start to decrease. For men belonging to the age group between 30 and 55, testosterone boosters help enhance levels of free testosterone.

Despite a rigorous workout and healthy diet, if you cannot get rid of body fat and are unable to build a well-toned, lean muscle, then opting for a testosterone booster can help.

Furthermore, the inability to sustain erections and lack of interest in sex can be addressed with testosterone boosters. The aforementioned issues can be attributed to low testosterone levels. The pills provide nourishment that contributes towards fixing the problems.

The recommended dosage is specified to boost testosterone by 30% or up to 50%. We believe Testogen, Prime Male, and Testo-Max are the best boosters available in the market.

When you decide to start taking a testosterone booster, consult a doctor, especially if you have a medical condition, and take other medications. Best Testosterone Booster Supplements of 2021
