Nugenix Reviews

Nugenix is a testosterone booster that helps boost natural testosterone levels.

As men age, natural testosterone levels in the body start to fall. This can lead to low sex drive, a loss in muscle mass, and even erectile dysfunction (1).

With this in mind, it’s no wonder men turn to testosterone supplements like Nugenix.

Our Nugenix review runs through everything you need to know about this natural testosterone booster before you buy. 

We compare Nugenix to other natural testosterone boosters like Testogen, Testofuel, and Testo-Max and give you the lowdown on the benefits and side effects of Nugenix.

Let’s get started.

Nugenix

What is Nugenix?

Nugenix produces a range of testosterone supplements that are designed to boost testosterone levels in men naturally. 

Thousands of men across the US take Nugenix to help boost sexual function, sexual desire, increase energy levels, and improve athletic performance (2).

Bodybuilders also use Nugenix as a bodybuilding supplement as it has been shown to help increase testosterone levels, which can make building lean muscle mass easier.

The most popular Nugenix products are Nugenix Free Testosterone Booster and Nugenix Total-T. However, Nugenix also produces multivitamins, sexual performance enhancers, thermogenic supplements, and energy boosters.

The truth is, Nugenix has received mixed reviews from customers. Some swear by Nugenix as the solution to combatting low testosterone; others have suffered unwanted side effects.

Why Nugenix Testosterone Boosters Have Received Negative Reviews

Like many testosterone boosters, Nugenix has received mixed reviews from customers.

Nugenix claims that their product helps to boost free testosterone levels in the body. This results in increased sex drive, sexual performance, energy levels, muscle growth, and improved athletic performance. 

This is down to the natural ingredients packed into Nugenix, which help the body accelerate testosterone production. 

However, Nugenix Free Testosterone Booster is not an FDA-approved supplement, which makes people cautious. And with so many alternatives on the market, the question remains whether there are better Nugenix alternatives out there.

Some of the side effects that people have complained about when taking Nugenix include; nausea, blood pressure changes, paranoia, and increased heart rate (3). Others have complained that they have received poor customer service or that Nugenix does not work.

To really understand, let’s take a look at how Nugenix ingredients compare to those in other popular testosterone boosters.

Popular Nugenix Alternatives

These days, there are so many brilliant supplements available to people looking to boost testosterone levels.

New brands like Testogen, Testofuel, Hunter, Prime Male, and Crazybulk have all launched t boosters and testosterone booster supplements to compete with Nugenix.

Let’s take a look at how these Nugenix alternatives stack up.

Testogen vs. Nugenix Free Testosterone Booster

 

Testogen

We’ve named Testogen the best testosterone booster in our top guide. 

Testogen contains D-Aspartic Acid, Magnesium, Vitamin D3, Nettle Leaf Extract, Korean Red Ginseng Extract, Bioperine, Fenugreek Extract, and a host of B Vitamins (Vitamin B6 and Vitamin B12).

This potent mix of natural testosterone boosters has been shown to boost testosterone, leading to increased muscle mass, stronger bones, enhanced libido, sex drive, and improved mood and confidence.

In fact, multiple scientific studies have shown that D-Aspartic Acid is a leading supplement for men who want to boost testosterone. 

In a recent study that looked at the impact of D-Aspartic Acid dietary supplements, men between the ages of 27-43 that took D-Aspartic Acid for 90 days saw a 30-60% increase in testosterone (4), (5).

While Nugenix contains Vitamin B6, Vitamin B12, Fenugreek Extract, and Zinc, Testogen contains higher doses across the board.

If you are looking for a t-booster high in L-Citrulline Malate, then Nugenix is a better option. However, if you are looking for t-boosters that contains D-Aspartic Acid, then pick Testogen.

The FDA also approves Testogen.

Hunter Test vs. Nugenix Ultimate

Hunter Test

Another top testosterone booster is HunterTest.

Hunter Test is developed by Roar Ambition alongside Testofuel and Prime Male and offers a popular alternative to Nugenix.

Hunter Test contains D-Aspartic Acid, Vitamin D3, and Indole 3 Carbinol. While D-Aspartic Acid and Vitamin D3 are fairly common testosterone booster ingredients (6), Indole 3 Carbinol sets Hunter Test apart.

Hunter Test contains 200mg of Indole-3-Carbinol per serving, which helps men boost lean muscle size safely.

On the other hand, if you are looking for a Nugenix dietary supplement packed full of D-Aspartic Acid, then Nugenix Ultimate is a great option.

Nugenix Ultimate contains 3,000mg of D-Aspartic Acid and 700mg of Fenugreek Seed Extract. Also, Nugenix Ultimate contains Stinging Nettle Extract, Boron, and Maca Root.

Testofuel vs. Nugenix Maxx

Testofuel

Nugenix Maxx is one of the most comprehensive supplements in the Nugenix product range. 

It contains 600mg of Ashwagandha, 600mg of Fenugreek Extract, 500mg of Shilajit Purified Extract, and Vitamin D, Rhodiola, Maca, Ginseng, Black Ginger, White Mushroom Extract, and Black Pepper Extract.

If you are looking for a comprehensive testosterone booster that contains a wide range of natural t-boosters, then Nugenix Maxx is a great option. But at nearly $170 per bottle, it doesn’t come cheap.

One popular alternative to Nugenix Maxx is Testofuel. While Testofuel does not contain the same volume of natural ingredients, it does contain a range of key ingredients that combine to have a similar effect.

These include D-Aspartic Acid, Vitamin D, Oyster Extract, Ginseng, Magnesium, Zinc, Fenugreek, Vitamin K2, and Vitamin B6.

Testofuel boosts testosterone levels, leading to fat loss (7), reduced estrogen (8), increased blood flow, enhanced sexual performance, and muscle growth.

The FCA also approves Testofuel.

Testo-Max vs. Nugenix Total-T

Crazybulk Testo-Max

Another top product in the Nugenix product range is Nugenix Total T.

Nugenix Total T is a free testosterone booster designed to boost muscle size, strength, energy levels, and sexual performance.

It contains L-Citrulline Malate, Fenugreek Extract, Vitamin B12, Vitamin B6, Zinc, Boron, Eurycoma Longifolia, and Peat Extract.

If you are looking for a bodybuilding testosterone supplement, then a popular alternative is Testo-Max by Crazybulk.

Testo-Max has a wider range of natural ingredients than Nugenix Total-T. Total-T contains a high dosage of l-Citrulline Malate (1,125mg) and Vitamin B12 (2,400mg), whereas Testo-Max contains a much higher dose of D-Aspartic Acid (2,352mg).

Testo-Max also contains Nettle Lead Extract, Ginseng Extract, Fenugreek Extract, Boron, Bioperine, Vitamin D3, Vitamin K1, Magnesium, Vitamin B6, and Zinc.

We’re unsure whether the FDA approves Nugenix Total-T, but we can confirm that the entire Crazybulk range (including Testo-Max) has the FDA seal of approval.

What Are Testosterone Boosters?

Testosterone boosters have exploded in popularity over the past couple of years.

The best t-boosters and testosterone supplements help men boost their natural, free testosterone levels by stimulating testosterone production in the testes.

This process helps men regulate natural hormone levels and combat the negative effects of reduced testosterone levels, which kick in after men pass 30 (9).

Testosterone boosters like Nugenix and Testogen help sustain increased t-levels, which in turn help men rebalance cortisol levels, stop testosterone from turning into estrogen, and increase the protein rate synthesis, which can support muscle growth.

The best testosterone boosters have also been shown to help men increase their natural sex drive, improve their mood and self-esteem, and prevent erectile dysfunction.

Do Testosterone Boosters Actually Work?

The short answer is yes.

Leading testosterone boosters like Nugenix, Testogen, and Testofuel help the body naturally produce more testosterone.

Numerous scientific studies have shown that when men have normal or heightened testosterone levels, they are less likely to suffer from serious medical conditions. What’s more, men with normal t-levels say that they are healthier, happier, and less stressed (10).

As men age, testosterone levels start to fall away. 

As this happens, many men start to find it hard to maintain lean muscle mass; instead, they suffer from stubborn fat build-up around their belly area. This results in a fall in natural metabolic and body fat that starts to secrete aromatase.

Aromatase is an enzyme responsible for converting testosterone into estrogen, which further contributes to negative hormone imbalance.

Nugenix Health Benefits

One of the main ingredients found in Nugenix products is L-Citrulline Malate.

Unlike other testosterone boosters like Testogen and Tesofuel, which focus on D-Aspartic Acid supplementation, both Nugenix Free Testosterone Booster and Nugenix Total-T contain the following doses of L-Citrulline Malate.

  • Nugenix Free Testosterone Booster – 2,103mg of Testosterone Complex (L-Citrulline Malate, Fenugreek Seed Extract, and Tribulus)
  • Nugenix Total-T – 1,125mg of L-Citrulline Malate

L-Citrulline Malate is a non-essential amino acid converted in the kidneys to L-Arginine (or nitric oxide) (11).

Nitric Oxide is one of the best pre-workout supplements for boosting energy levels. It helps to boost athletic performance by increasing vascularity, blood flow, and muscle pump.

Nugenix uses L-Citrulline in their t-boosters because it boosts athletic performance and helps men increase blood flow and fight erectile dysfunction (12).

With that said, our advice is to pick a Nugenix product or competing Nugenix product if you are focused on specifically increasing testosterone levels.

Testogen and Testofuel focus instead on D-Aspartic supplementation, which has been shown to boost natural testosterone levels, leading to the following health benefits:

  • Build Lean Muscle Mass & Promote Muscle Growth
  • Develop Strong Healthy Bones
  • Improve Cardiovascular Health
  • Enhanced Sex Drive & Libido
  • Improved Mood & Cognitive Performance

If you are set on purchasing a Nugenix testosterone booster, then Nugenix Maxx contains a high D-Aspartic Acid and Fenugreek dose.

Nugenix Side Effects

Like other natural testosterone boosters, there aren’t any side effects you need to be worried about when you take Nugenix products.

That’s because all of the key ingredients are naturally occurring and can also be found in a healthy diet.

With that said, always stick to the recommended dosage of Nugenix and seek medical advice if you have a pre-existing health problem.

While they are uncommon, some people have experienced the following negative side effects when taking testosterone boosters (13).

  • Nausea
  • Upset Stomach
  • Increase Heart Beat
  • Disrupted Sleep (14)
  • Anxiety
  • Swollen Limbs

We’d always advise taking dietary supplements that have received approval by the FDA and manufactured in the United Stated under GMP-Certified manufacturing processes.

Nugenix FAQ

Whenever we carry out a testosterone booster review, we always try to answer the questions before getting started.

Here are answers to some of the most commonly asked questions about Nugenix.

How Should I Take Nugenix?

The majority of Nugenix products are taken in capsule form.

The more popular Nugenix products like Nugenix Total-T, Nugenix Free Testosterone, and Nugenix Maxx require you to take 3 capsules with water every day.

With that said, other Nugenix products like PM-NMA require you to take 4 capsules per day and to make sure you take them before bed.

All of the Nugenix supplements outline the dosage recommendations on the back of their bottles. Make sure you always follow this guidance, and if you are worried, seek medical advice.

How Long Until Nugenix Takes Effect?

It can take anywhere from a couple of weeks to a month before you start to see results.

Within just a few days, you should start to feel a boost in your virility. This might be in the form of stronger erections, improved body composition, or a more competitive mindset.

But to truly reap the benefits of using testosterone boosters, we’d recommend that you wait for at least a month, and for the best results, supplement for at least three months.

Where Can I Buy Nugenix?

Nugenix is available at a host of retailers in the United States like GNC, Amazon, Vitamin World, The Vitamin Shoppe, and others.

You can also buy Nugenix via their official website.

Where Is Nugenix Manufactured?

Nugenix products are manufactured in the United States and Canada.
