What Is Testosterone?

Testosterone is the major sex hormone in males responsible for the development of the penis, testes, and male voice.

In adulthood, testosterone is necessary for normal sperm development, fertility, sex drive, and muscle growth. Total testosterone levels are a combination of free testosterone, which is not bound by sex hormone-binding globulin (SHBG) and bound testosterone.

In short, testosterone directly contributed to one’s biological manhood. High testosterone levels are the main reason men have more muscle and strength than women.

How Does Testosterone Work?

Besides being a sex hormone produced by the human body, testosterone is also an anabolic steroid prescribed and/or used by humans to treat low testosterone levels, infertility, as well as breast cancer in women.

Most anabolic steroids and other testosterone treatments might create some serious health issues like kidney failure. However, many natural testosterone supplements are legal and perfectly beneficial for men who suffer from low testosterone levels and erectile dysfunction.

Testosterone deficiency may be caused by a medical condition, genetics, and aging. Studies show that after the age of 40, 1.6% of your testosterone levels drop each year [6]. Science is still working on what levels of testosterone are significant and how to optimize them.

What Are Normal Testosterone Levels by Age and How To Determine Reduced T-Levels?

Healthy testosterone levels in men depend on protein status, thyroid function, genes, diet, and other factors. By consensus, multiple medical authorities consider 350 ng/dl to be the minimum normal testosterone level [7]. Below that, men are diagnosed with testosterone deficiency and in need of treatment.

Another study focused on non-obese American and European men (19-39 years old) found that the average testosterone levels are between 264-916 ng/dL [8]. These two data show that men with normal and those with low testosterone levels might have a difference of only 200 ng/dl, since lower t-levels aren’t recorded.

The most accurate way to determine if your body is producing enough testosterone is through a blood test where your doctor can evaluate your hormone levels. But, there are some signs of low testosterone which you can detect in your daily life.

Signs of low testosterone include:

  • Low sexual desire and libido
  • Fewer erections
  • Impotence and erectile dysfunction
  • Loss of sleep
  • Difficulty to focus, concrete, and stay motivated
  • The decline in cognitive functions
  • Loss of muscle mass
  • Chronic fatigue and depression

What Causes Men’s Testosterone To Fall?

A decline in testosterone levels happens when the male testes can’t produce enough testosterone because of testicle trauma, or a condition affecting the pituitary gland or hypothalamus. Also, diabetic and obese people are more prone to low testosterone levels.

Thus, testosterone deficiency can be a metabolic disorder or a genetic condition. A third important factor is age. T- levels fluctuate during different periods of life, they raise when one hits puberty, and start a constant decline after the age of 30 [9].

Other less common factors that might lead to low testosterone levels are overtraining, lack of a nutritious diet, and consumption of drugs and alcohol. But, any drop in testosterone levels is not permanent and there are multiple ways to make your body produce more testosterone.

What Are the Benefits of Having High Testosterone Levels?

Having high testosterone levels is more than just experiencing a high sex drive and longer erections. Men with high testosterone levels age better, they lose less hair, their heart and kidneys stay strong and can maintain lean muscle mass with ease.

Problems like infertility, impotence, and erectile dysfunction are closely related to very low testosterone levels and the inability of the body to produce this crucial hormone.

On the other, having optimum t-levels enables the body to better regulate the energy and keep metabolism young. Lastly, high testosterone levels elevate moods and sex drive. You’ll desire your partner more and feel better about your body and manhood.

The potential benefits of high testosterone include:

  • Better sleep
  • Boosted energy and focus
  • Easier muscle growth and weight loss
  • Reduced risk of cardiovascular conditions and/or prostate-related problems
  • Increased sex drive and pleasure

What Are Testosterone Boosters and How Do They Work?

Testosterone boosters, like the ones reviewed in this article, are supplements with active ingredients used to boost testosterone production. Different from hormonal injections or steroids, they don’t include any hormones in them.

Their formulas include ingredients that boost testosterone naturally. While all of them contain D-aspartic acid, they differ in combinations of herbs, minerals, and vitamins. No matter what you read, natural testosterone boosters can only increase your t levels by as much as 50%.

Keep in mind that the same testosterone booster that increased the t levels of somebody by 50% might be less effective for you. That shouldn’t discourage you from using testosterone boosters if you have testosterone deficiency.

Common Ingredients Found in Testosterone Boosting Supplements

Below are some of the most common ingredients found in natural testosterone boosters:

  • D-Aspartic Acid

D-aspartic acid is an amino acid that regulates the production and release of testosterone and increases testosterone levels by 30-60% [10]. D-aspartic acid is often combined with zinc, ginseng and vitamin D3 because these natural ingredients optimize DAA’s performance. 

  • Ashwagandha Extract

Ashwagandha, commonly known as Indian Ginseng is a herb that benefits sperm count and muscle mass gains [11, 12]. In another study conducted on ageing, overweight men saw an increase in their testosterone levels after 8 weeks of ashwagandha supplementation [13].

  • Vitamins 

We already know how important vitamins are for our overall well-being. But, recent studies suggest that some vitamins, such as B, B12, B6, D, K, and E, play an important role in supporting the body to regulate testosterone levels [14].

  • Zinc

Testosterone deficiencies are related to zinc deficiency due to the role zinc plays in the synthesis of testosterone as well as the quality of sperm [15]. 

  • Nettle Leaf Extract

The Nettle leaf extract is a powerful aphrodisiac that binds with sex hormone-binding globulin (SHBG) which releases testosterone to perform other duties. This extract is great for muscle growth and libido.

  • Fenugreek Extract

Fenugreek extract is used to enhance libido and help with preventing diabetes. Clinical trials indicate that this supplement impacts total testosterone levels in males as well as improves sexual performance [16, 17].

  • Red Ginseng Extract

Red ginseng extract is another aphrodisiac that testosterone boosters use in their formulas. It raises testosterone levels and helps with sex drive and performance [18] Also, it’s great for enhancing concentration and focus.

  • Boron

Boron supplementation is proven to increase total testosterone, lean body mass, and strength in men [19]. A 2015 review found that daily supplementation of 6 gr of boron increased testosterone levels by as much as 25% [20].

What Are the Side Effects of Taking Testosterone Boosters?

The side effects of testosterone boosters depend on the ingredient list and their formulation concerning your own body needs or other specific medical conditions. Nonetheless, we guarantee that the testosterone boosters in this article have zero side effects.

We make sure to thoroughly research all the products that we offer you in this review. They are all FDA-approved and pack the best ingredients there are. The only thing you have to keep in mind when choosing testosterone supplements is sticking to all-natural ones.

If you have any medical conditions or are over 60 years old, make sure to check any testosterone booster with your doctor before deciding to buy. Your doctor will let you know if the formula or any of the ingredients interferes with other treatments you might be taking.

Choosing GMP-certified and FDA-approved manufacturers as well as a 100% organic and safe ingredient list will keep you away from having side effects. This means steering away from steroids which would lead to hair loss, acne, prostate enlargement, and even kidney failure.

How to Increase Testosterone Levels Naturally

The best way to increase testosterone levels is through a natural testosterone booster. Stay away from any steroids, hormonal injections, or unclean testosterone supplements. Especially for men over 40, the best testosterone booster will not be one with artificial ingredients.

It’s better to choose a formula with herbs, extracts, micronutrients, and amino acids that will boost testosterone levels naturally without interfering with your other organs such as the kidneys and heart.

Formulations with ingredients that are synthetically made, or steroid-based testosterone boosters might help in the short term, but they will bring major hormonal disbalances and even kidney failure.

If you’re looking for a testosterone booster check if they include D-Aspartic Acid, vitamins B6, B3, K2, zinc, magnesium, boron, ashwagandha, etc. These ingredients won’t give you any long-lasting or fatal side effects.

Other important habits to enhance your body’s natural testosterone production include:

  • Exercise
  • Quality sleep
  • Cutting down alcohol
  • Caffeine

Best Foods and Vitamins for Testosterone Production

In terms of nutrition, the best thing you can do for your sex hormones and your body, in general, is to prioritize whole foods, complex carbs, lean protein sources, and healthy fats. These foods are thought to help your body produce and release more testosterone:

  • Fatty Fish
  • Oysters
  • Eggs
  • Avocado
  • Olive Oil
  • Spinach
  • Cocoa
  • Bananas
  • Kiwi
  • Pomegranates


What are the signs of low testosterone in men over 40?

Any of our recommended t-boosters start to show results after a few weeks of usage. Some products, such as TestoGen, give you an immediate elevation of mood and energy, but others might take longer.

Why would older men need to increase testosterone production?

Higher levels of testosterone make exercising easier and help build muscle mass. Testosterone increases bone density and aids in manufacturing red blood cells. Also, more testosterone means more energy and a better mood to perform all your activities without feeling fatigued.

At what point do I stop using testosterone boosters?

You can stop using your testosterone booster whenever you want, but that will lead to a testosterone drop to the pre-testosterone booster levels.

How much do testosterone supplements cost?

The cost of a testosterone booster varies from brand to brand. In the case of similar testosterone boosters mentioned in this article, the prices vary from $40-100 per month supply.


Testosterone levels are closely related to a men’s quality of life. If you want to stay young and have the energy and power to face the demands of today’s life, you have to be on top of the game with the essential male hormone.

Obtaining high levels of testosterone means continuing to be sexually active, both in giving and receiving pleasure. Also, you’ll look and feel younger as well as have no difficulty gaining muscle or losing weight.

The best way to do this is by adding one of the best testosterone booster supplements to your diet. Each of these products starts showing results in just a few weeks and will help you get ahead of prostate and erection problems that might come with age.
