We rated Prime Male as our top pick as an all round natural testosterone booster. 

As such you can probably guess that this is going to be a positive review of the product. 

Now, we should specify, that a lot of the science on plant compounds and their effects on testosterone production is relatively new and is far from conclusive. But, when we look at the information that is currently available, Prime Male does offer the most comprehensive formula and does look very much like it should be the best on the market.

There's a few reasons for this, when we look at meta analysis of the individiual ingredients, Prime Male focuses on the most well backed options. 

It covers off the 5 vitamins and minerals that we would wawnt to see, covering off the deficiencies that can cause low testosterone which is a great start. [1,2] Especially as these deficiencies can effect upwards of 50% of men, especially those over 50 in the case of vitamin d. [3,4]

Next up we've got Ashwaganda, Luteolin and Ginseng, which are by and large the best options. [5,6,7] There's a large dose of DAA which may or may not raise testosterone levels, but definitely contributes to lean muscle mass gains, which is the most common reason people look for a testosterone booster.  [8]

We've then got boron, which should be in all good combined testosterone supplements as it takes up a very small amount of capsule space (5-10mg) and is very well backed for raising testosterone production. [9]

Then we have the fact that Prime Male has been on the market for 10 years and it's parent company Roar Ambition Ltd has a very good reputation, no complaints about unauthorized billing, and has updated the formula when new research has come out. There's a host of positive customer reviews and all in all we don't really have any complaints about the product. Which is rare for a testosterone booster supplement. As such, we recommend Prime Male Vitality.

What Is Prime Male?

Prime Male, created by Roar Ambition, is a popular testosterone-boosting supplement that aims to restore and enhance overall health and vitality. It is specifically formulated for men who are experiencing the symptoms of low testosterone, such as fatigue, decreased muscle mass, and reduced libido. Unlike synthetic testosterone replacement therapy, Prime Male takes a natural approach by stimulating the body's own testosterone production.

Does Prime Male Work?

Prime Male works by targeting the root cause of low testosterone levels and providing the body with the necessary nutrients to boost production. The supplement contains a blend of carefully selected ingredients that have been scientifically proven to support testosterone synthesis. By increasing testosterone levels, Prime Male helps improve energy levels, enhance libido, build lean muscle mass, and promote overall well-being.

The key to Prime Male's effectiveness lies in its ability to stimulate the production of luteinizing hormone (LH). [10] LH plays a crucial role in regulating testosterone production in the testes. Prime Male contains ingredients that activate the release of LH, leading to increased testosterone synthesis. Additionally, the supplement includes ingredients that help reduce estrogen levels, further optimizing testosterone production.

Prime Male Benefits

Prime Male offers a wide range of benefits that go beyond just boosting testosterone levels. Let's take a closer look at some of the key advantages of incorporating Prime Male into your daily routine:

Increased Energy and Reduced Fatigue

One of the most noticeable benefits of using Prime Male is the increase in energy levels. As testosterone levels decline, many men experience fatigue and a lack of motivation. Prime Male contains ingredients like Vitamin D3, Vitamin B6, and ashwagandha extract, which work together to combat fatigue and promote energy release. [12,13] By restoring healthy testosterone production, Prime Male helps you regain your vitality and enjoy daily activities to the fullest.

Improved Libido and Sexual Performance

Low testosterone levels can have a significant impact on libido and sexual performance. Prime Male addresses this issue by including ingredients like D-aspartic acid calcium chelate, which acts as both an estrogen blocker and a testosterone booster. By reducing estrogen levels and increasing testosterone production, Prime Male helps restore and enhance libido, improve sperm quality, increase dopamine production, and contribute to overall sexual well-being. [14]

Enhanced Muscle Mass and Strength

Another benefit of Prime Male is its ability to support the development of lean muscle mass and increase strength. Testosterone plays a crucial role in muscle growth and repair. By naturally boosting testosterone levels, Prime Male provides an environment conducive to muscle development. Combined with regular exercise and proper nutrition, Prime Male can help you achieve your fitness goals more effectively.

Improved Cognitive Function

Testosterone is not only important for physical health but also for cognitive function. Studies have shown that low testosterone levels can lead to cognitive decline, including memory loss and difficulty concentrating. Prime Male contains ingredients like magnesium, which supports hormone synthesis and regulates cortisol and estrogen levels. By optimizing testosterone production, Prime Male can potentially improve cognitive function and mental clarity.

Prime Male Ingredients

Prime Male's effectiveness is attributed to its carefully selected blend of ingredients. Let's take a closer look at the key components of Prime Male and their respective benefits:

Ashwagandha (300mg): Ashwagandha is a powerful herb that has been used in Ayurvedic medicine for centuries. It has been shown to reduce stress levels and increase testosterone production by up to 15%. Ashwagandha also helps reduce cortisol levels, leading to improved sleep quality and mood. Additionally, it may enhance male libido and sexual performance. [5,15]

D-Aspartic Acid Calcium Chelate (1600mg): D-Aspartic acid is an amino acid that regulates estrogen production and promotes higher levels of free testosterone in the body. By inhibiting the conversion of testosterone into estrogen, D-aspartic acid helps maintain elevated testosterone levels. It also supports the release of luteinizing hormone, which is essential for testosterone synthesis. [8,14,16]

Zinc (30mg): Zinc citrate is a highly absorbable form of zinc, an essential mineral for testosterone production. Zinc facilitates the release of luteinizing hormone from the pituitary gland, which stimulates the testes to produce more testosterone. Additionally, zinc citrate supports immune system function, reduces inflammation, promotes wound healing, and may improve memory and cognitive function.  [1]

Luteolin (60mg):  Luteolin is a flavonoid that blocks the creation of estrogen, thereby improving tissue development, muscle-building, and addressing sexual issues like erectile dysfunction. Specifically luteolin acts as a testosterone stimulator by blocking the enzyme aromatase, which converts testosterone into estrogen. By preventing this conversion, luteolin helps maintain elevated testosterone levels. It also possesses anti-inflammatory properties and has been shown to improve overall health and performance. [7,17]

Magnesium (100mg): Magnesium plays a crucial role in muscle relaxation, supporting exercise and muscle-building efforts. It also increases free and total testosterone by limiting the amount of SHBG in the body. Magnesium is an essential mineral that plays a crucial role in hormone synthesis. It stimulates the release of luteinizing hormone, supports testosterone production, and regulates estrogen and cortisol levels. Magnesium also has the potential to reduce anxiety and stress, further contributing to increased testosterone levels. [18]

Nettle Root (160mg): Nettle root actively increases testosterone levels by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). By maintaining high testosterone levels and preventing the conversion to DHT, nettle root supports testosterone optimization. It also possesses anti-inflammatory properties and may benefit prostate health. [19]

Korean Red Ginseng (120mg): Korean Red Ginseng is a natural androgen supplement that has been shown to increase testosterone levels and luteinizing hormone, enhancing overall hormonal balance. It's also particularly beneficial for stress and mood, having the same double function as ashwagandha, as well as contributing to libido, meaning that Prime Male scores very highly for mood and may well be the best testosterone booster for mood as well as the best overall. [6,20]

Vitamin D3 (100mg): Research suggests that vitamin D3 supplementation can increase testosterone levels and luteinizing hormone. [3]

Vitamin B6 (17.5mg): Vitamin B6 plays a critical role in testosterone production and functionality. [21]

 Vitamin K2 (45mcg): Studies indicate that vitamin K2 positively affects cellular pathways in the testes, promoting accelerated testosterone production. It's important to use k2 specifically as this is what's used to produce testosterone and whilst k1 can be converted it's a very inefficient process. [2,22]

Boron (5mg) Boron helps the body utilize testosterone, vitamin D, magnesium, and estrogen more effectively. By optimizing the utilization of these essential compounds, Boron enhances the core benefits delivered by Prime Male. [9]

Bioperine (10mg): Bioperine stimulates pubertal Leydig cell development, increasing testosterone production. Additionally, it aids in the absorption of other ingredients in the Prime Male formula, ensuring their maximum effectiveness. [23]
