Having low testosterone levels can lead to difficulties regulating your mood and may even lead to an aggravation of an existing mood disorder. In addition, lower testosterone can also have a negative impact on muscle mass, sex drive, and more. The good news is that these effects can be combated with the use of testosterone boosters that are made from natural ingredients, providing a natural, healthy – and safe - alternative to other products on the market.

Before you dive into learning more about the boosters available, we’ll answer some of your main questions about whether they are safe, whether they really work, and more. To get started, here’s a quick look at the best options on the market:

  • Strongest: Testogen
  • Best for building muscle: Testofuel
  • Best for men 40+: Prime Male

How We Chose These Products:

Deciding the best ones out of a range of different testosterone supplements was certainly not easy, so we asked our readers to put it to the vote. A poll of 300 people has enabled us to offer reviews that are as honest and as accurate as you get. 

#1. Testogen: The Strongest Testosterone Booster

Testogen is a popular choice. It is the ideal choice for you if you are currently struggling with low moods, have noticed a decline in your sex drive, you are struggling to build muscle, or have fat in your tummy area. If you read my full testogen review you will see why its my favorite testosterone booster.


There are eleven ingredients in testosterone boosters from Testogen. These are:

  • Boron (8mg): Boron is an ingredient that can be found in anything from fruits to the soil. Although 8mg might not seem like much, even the smallest levels of this mineral are able to boost testosterone levels in the body. 
  • Bioperine 95% Piperine (5mg): This ingredient is created from black pepper, and its function is to allow the other ingredients in the booster to be processed in your body more efficiently. 
  • Zinc (10mg): Zinc is a key component when it comes to maintaining healthy bodily functions and a healthy sperm count. 
  • Vitamin B6 (20mg): This is one of the most important vitamins to consume. Studies suggest that vitamin B6 is linked closely to testosterone production. Deficiencies can lead to reduced levels of testosterone in your body.  
  • Vitamin K1 (20mcg): You may already know about the health benefits of this vitamin, which include maintaining healthy nails and bones. It’s also an important vitamin for boosting testosterone levels.
  • Fenugreek Extract (40mg): Fenugreek extract is considered to be a natural way of increasing testosterone levels in your body and boosting your libido. 
  • Korean Red Ginseng Extract (40mg): This extract has a number of health benefits including boosting your libido and improving your overall physical and mental health.
  • Nettle Leaf Extract (40mg): Testosterone attaches to a protein called SHGB, at which point it no longer functions the same way as free-flowing protein. Nettle leaf also joins SHGB, allowing more protein to circulate around your body and helping to increase your muscle. 
  • Vitamin D3 (50mg): This vitamin might not be the most well-known, but it can significantly boost your level of testosterone and help to slow the transition of testosterone to estrogen. 
  • Magnesium (200mg): This mineral is essential in every diet, and you will usually find it in most supplements. Studies show that people who consume just 750mg of magnesium on a daily basis enjoyed a 25% increase in testosterone levels. Magnesium can also help with sleep, which in turn can improve testosterone. 
  • D-Aspartic Acid (2352mg): This is an amino acid that aids your body in producing and regulating hormones. It can enhance testosterone production by up to 45%. 

How It Works:

The fact that all the ingredients used in Testogen are natural is a major selling point for this product. The combination of eleven natural ingredients will safely and naturally increase your testosterone levels while avoiding any synthetic ingredients or products. 

While some products will simply provide a testosterone supplement, Testogen works differently by boosting your natural system and providing your body with the minerals and vitamins that it needs to naturally produce more testosterone. Consume four capsules at breakfast in the morning for the best results.


  • Helps with building strength
  • Leads to fat loss
  • Increases focus and energy


  • Some users say it is quite expensive

Why Buy This Product?

Not producing enough testosterone can lead to difficulty in your daily life. However, many of the supplements available will contain unnatural testosterone, which can be dangerous. This product can naturally increase testosterone levels without any side effects. Whether you want to boost your mood, energy, sex drive, sleep, or muscle mass, Testogen has you covered.

#2. Prime Male: Best for Men Over 40

Prime Male has a reputation for being one of the best testosterone boosters available for older men in particular. It was created over a number of years, resulting in the perfect supplement for men who are not getting enough testosterone from their diet. While adding the right types of food to your diet can help you achieve similar results over time, this supplement is designed to help you enjoy the same health benefits in a much shorter time, and at a lower cost in the long-term.


Prime Male is made up of twelve testosterone-boosting ingredients, which are: 

  • Boron: Boron reduces inflammation in your body, improves joint health, and boosts testosterone levels. 
  • Bioperine:The amount of BioPerine included in Prime Male makes it easier for your body to process nutrients, and helps your body restore protein levels. 
  • Nettle Root: Nettle Root or nettle leaf allows for more free testosterone to move through your system by attaching to SHGB
  • Mucuna Pruriens: High levels of estrogen are one of the main causes of low testosterone levels in men. Mucuna Pruriens is a natural levodopa source. Levodopa is an amino acid that encourages human growth hormone and testosterone levels. As a result, it makes building muscle easier and helps you maintain your strength.
  • Luteolin: This is one of the most powerful inhibitors of aromatase. Since it has such a profound effect on aromatase, it also works to prevent the production and storage of excess estrogen in your system
  • Ginseng: Ginseng is often used for its medicinal properties, particularly for its positive effects on the immune system. Those who consume it over the long-term will often enjoy a longer lifespan. It’s used in Prime Male for both these health benefits and its effect on boosting testosterone
  • D-Aspartic Acid: Along with being an amino acid, this ingredient is also a neurotransmitter. This function of D-Aspartic Acid allows your body to create more testosterone. It is particularly useful for men who are suffering from infertility with some men experiencing a 50-100% sperm count increase
  • Zinc: Low zinc levels can cause your pituitary gland to stop or slow the regulation and production of specific hormones. Optimum levels of zinc in the body help to stimulate testosterone production. 
  • Magnesium: Magnesium has an effect on your SHBG count, a compound that typically, testosterone will bind to. Reducing your SHGB count with magnesium allows testosterone to flow more freely around the body. 

  • Vitamin B6: Estrogen and testosterone are not the only hormones that your body contains. You also have levels of androgen, which is considered a precursor to testosterone. Vitamin B6 is an ingredient that boosts androgen levels in your body, therefore increasing your testosterone levels as a result. Vitamin B6 can also help with the mood symptoms that are often associated with low testosterone levels
  • Vitamin K2: This vitamin can balance your hormones and improve your sex drive. It can also help you lower your risk of erectile dysfunction.
  • Vitamin D3: Although you will usually get this vitamin through sunlight exposure, many people miss this essential nutrient. People who are deficient in Vitamin D will often have unbalanced hormones and it may lead to a shorter lifespan

How it Works:

Prime Male is targeted at older men. It works by increasing testosterone and reducing estrogen levels in the body, helping to restore them to what they once were. 


  • Increased strength
  • Libido boost
  • Better energy levels
  • Mood stabilization


  • You may not see many benefits due to lower levels of ginseng

Why Buy This Product?

If you are looking for a supplement that benefits hormone levels as well as overall health, this product is ideal for you. The above ingredients allow Prime Male to go above and beyond simply prioritizing hormones and does a lot more than simply increasing levels of testosterone. Instead, the ideal amount of ingredients combined also helps your immune system and reduces other physical symptoms such as joint discomfort and inflammation.

#3. Testofuel: Best for Building Muscle

The ingredients in TestoFuel have been carefully chosen to ensure that you enjoy the best possible quality and can help whether you want to improve your muscle mass, stabilize your mood, or more. 

  • Zinc: A mineral that communicates to your body that it needs to increase testosterone production. 
  • Vitamin K2: Also known as menaquinone, this vitamin is commonly found in high-protein organs and meats. The benefit of including it in this supplement is that you can experience the benefits without the high levels of fat that you would normally consume from organs and red meat. When it is combined with vitamin D3, this vitamin doubles down on testosterone production and causes the hormone to be more easily released into the body. It can lead to significant increases in testosterone production in just five weeks. 
  • Vitamin B6: Also known as pyridoxine, this vitamin is an essential nutrient for improving your everyday life. It has a very positive effect on your hormones along with promoting healthy skin, hair, eyes, and organs such as your liver. Vitamin B6 also regulates hemoglobin, allowing for easier transportation of blood through your system. It’s an ingredient that improves both overall health and testosterone levels. 
  • Magnesium: This mineral will help in the production and regulation of several enzymes in the body. It promotes a healthy heart, brain, and bones, and boosts your metabolism. 
  • Fenugreek: This ingredient is filled with some of the other ingredients on this list, such as magnesium and zinc. It also contains selenium, and when combined together the three promote an increase in free-roaming testosterone in the body and allow it to be as effective as possible. 
  • Ginseng: This ingredient is a powerhouse when it comes to testosterone boosting. It can also have a positive impact on your immune system and boost your sex drive, along with increasing your focus and helping you sleep better. It leads to an increase of nitric acid in the body, which promotes fat loss and muscle building. 
  • Oyster Extract: This ingredient is known for its properties as an aphrodisiac and for boosting testosterone. In addition, oysters are extremely high in zinc, which promotes a healthy reproductive function. 
  • Vitamin D: This vitamin will give your system an additional boost, even if you are getting plenty of it from your diet or sunlight. Studies have shown vitamin D to increase athletic performance and boost testosterone levels. 
  • D-Aspartic Acid: This ingredient boosts testosterone levels, encourages muscle production, and regulates the luteinizing hormones, which communicates with your system to produce more testosterone. It can help increase your sperm count up to 100%.

Are testosterone boosters the same as steroids?

No. Testosterone boosters are designed to help your body naturally produce more testosterone and regulate your hormones.
