A common problem among men in their 40s is a decrease in testosterone levels - a condition that can lead to a number of mental and physical problems.

Fortunately, several natural testosterone boosters on the market promise to help solve this problem. One of them is the Nugenix Free Testosterone Booster.

After our team spent hundreds of hours researching whether this supplement is true to its claims, I decided to give it a try.

Here's our Nugenix review.

What Is Nugenix?

Nugenix is an all-natural free testosterone booster featuring six key ingredients designed to support healthy levels of free testosterone in men.

Aside from raising testosterone, this product claims to help men feel stronger and have a higher sex drive.

Over-the-counter testosterone boosters like Nugenix are considered safer than hormone replacement therapy, making them a popular natural alternative among many men.

About the Brand

This free testosterone booster is manufactured by Adaptive Health, formerly known as Direct Digital.

Adaptive Health is an industry leader known for developing a vast portfolio of nutritional health brands, including Nugenix®, Sleep Answer®, and OxyRub®.

The company, which has offices in Bethesda, Charlotte, and Boston, rebranded after acquiring Healthy Directions in December 2017.

It has a good reputation for producing clinically proven products, which are also sold internationally.

How It Works?

Nugenix aims to help the body restore healthy levels of free testosterone using its main ingredient, Testofen®.

With its combination of herb and plant-based extracts and vitamins and minerals, this product stimulates body processes that trigger free testosterone production.

While total testosterone score plays a vital role in the male body, free testosterone is considered more important.

That's because free (or bioavailable) testosterone is the amount of this hormone that the body can use.

"After age 30, most men begin to experience a gradual decline in testosterone." - David Samadi, Board-Certified Urologist

Men with low testosterone can experience hair loss, fatigue, muscle loss, increased body fat, mood changes, poor memory, and smaller testicle size.

They're also at an increased risk of diabetes, obesity, heart disease, depression, and erectile dysfunction.

Testosterone-boosting supplements, including Nugenix, claim that men can build more muscle mass, enjoy enhanced sexual function, and feel stronger overall with improved T-levels.

Ingredients

Nugenix Supplement Facts

Nugenix Free Testosterone Booster contains a compound of six key ingredients that have been tested for maximum effectiveness.

Let's take a look at what each ingredient in this supplement does.

Vitamin B6 (Pyridoxine Hydrochloride) - 2 mg per serving - B-vitamins play an important role in energy production and protein metabolism.

According to several dated studies, lab animals with vitamin B6 deficiency had lower serum testosterone levels than animals supplemented with vitamin B6 [1].

Some research also shows that the more you exercise, the more your body needs vitamin B6 [2].

According to our in-house dietitian, Nugenix likely added B6 to its formulation for its "energizing" capabilities.

Vitamin B12 (Methylcobalamin) - 50 mcg per serving - This nutrient helps keep your body’s blood and nerve cells healthy [3].

Although there’s no link between testosterone production and vitamin B12, many energizing supplements include it to increase energy levels and enhance athletic performance.

Zinc (Zinc Chelate) - 1 mg per serving - Research on zinc showed that its levels significantly decrease following exercise, suggesting that it's linked to muscle recovery [4].

A small study on male wrestlers found that their free testosterone levels increased after taking zinc supplements for four weeks [5].

Nugenix Free Testosterone Complex - 2103 mg per serving - This part of the formula refers to the patent complex only used in the manufacturing process of Nugenix Free Testosterone Booster.

Here are the ingredients making up this proprietary blend:

L-Citrulline Malate - This amino acid helps detoxify the liver and expel ammonia.

It's also converted to another amino acid, L-arginine, which produces nitric oxide that dilates blood vessels and promotes healthy blood flow.

Having low levels of nitric oxide is linked to erectile dysfunction.

There's also some evidence suggesting that L-citrulline can improve symptoms of mild erectile dysfunction [6].

Testofen® Fenugreek Seed Extract - Testofen®, the main ingredient of Nugenix, contains fenusides from fenugreek.

This compound contains powerful anabolic properties that may help boost muscle tone, growth, and strength.

Fenugreek seed extract may also help boost your libido and have anti-diabetic effects.

One study concluded that fenugreek could improve levels of both total and free testosterone [7].

Tribulus Fruit Extract - Tribulus Terrestris is an herb often found in testosterone supplements, but there are mixed findings regarding its effectiveness.

According to several studies, Tribulus supplementation can't boost testosterone levels or cure impotence, but it may improve libido [8,9].

Benefits and Highlights

The supplement claims to deliver a multitude of health benefits, such as:

  • Increase testosterone levels
  • Maximize muscle-building
  • Boost energy
  • Boost libido
  • Enhance fitness
  • Stabilize cortisol levels
  • Give better blood flow
  • Improve vitality

As someone who trains at the gym regularly, I can say that I was pretty satisfied with Nugenix's effects on my stamina.

By week four, I had started noticing an improvement in my exercise performance. I could do more bench presses and run 15 minutes more than my average time on the treadmill.

However, these benefits came with a downside- agitation. I constantly felt the need to move and exhaust myself because I had boundless energy. This side effect eventually stopped.

Pros
  • Boosts energy
  • Improves mood and focus
  • Increases stamina and libido
  • Made of all-natural ingredients
Cons
  • Proprietary formula
  • May cause slight agitation during the initial weeks of intake

Our Rating on This Testosterone Booster:

  2. Price: 3.5/5

Where To Buy It?

capsules and container

You can buy Nugenix Free Testosterone Booster from drug stores like CVS, Rite Aid, Walgreens, and supplements stores like GNC.

Each bottle contains 90 capsules for a month's supply, and I can say it’s competitively priced among other top T-boosters in the market.

The product will be shipped the day after you place an order and should be at your doorstep one to five business days later.

The company can also ship to P.O. boxes.

How To Use It?

Users are advised to take three capsules of Nugenix Testosterone Booster with water and on an empty stomach.

You might find it more beneficial to take this supplement 30 to 45 minutes before exercising during workout days.

On non-workout days, it's better to take it in the morning.

If you miss a dose, just go about your usual schedule and don't bother to catch up.

How Nugenix Compares To Other Testosterone Boosters?

If you want to explore options outside Nugenix, there are other good T-boosters you might want to consider.

Testofuel

Testofuel is an all-natural testosterone booster that delivers muscle-building benefits. I have tried this supplement, and I can say that it works as advertised.

It sped up my recovery and improved my libido, mood, and energy. Within a few weeks of using Testofuel, I already had visible muscle gains on my chest and arms.

Another thing I love about Testofuel is its transparency. The label indicates exactly how much of each ingredient you’re getting per serving, so you know what you’re paying for.

Testogen

Testogen is a testosterone-boosting supplement that increases your energy, focus, muscle mass, and sex drive.

Like Nugenix, this product improved my energy levels and had a positive effect on my mood.

Within two months of taking Testogen, I managed to reduce my body fat percentage by 2%. I also felt stronger and noticed a slight growth in my bicep muscles.

Testogen offers a 60-day money-back guarantee if you’re not completely satisfied with its performance.

Aphro-D

Aphro-D is a herbal supplement that boosts testosterone, enhances physical performance, and increases sex drive.

I’ve also used this product, and it made me feel more energized and confident.

But if you’re looking for quick results, Aphro-D might not be the suitable product for you. In my experience, it might take at least two months of consistent use to experience its benefits.

The company also offers a 365-day full money-back guarantee on this supplement.

Customer Reviews

We scoured the internet for feedback on this testosterone booster, and we found some mixed reviews from users. Here are some of them.

As a 53-year-old man, Rich sometimes feels run down. With a very physical job, he noticed a big difference in his energy ever since taking Nugenix. The supplement also significantly increased his sexual stamina.  - Rich - Chandler, Arizona

Michael is a long-time user of Nugenix. He has been taking the supplement for around two years and noticed a great improvement in his mood and energy. Although he doesn’t have testosterone or erectile dysfunction issues, he plans to continue using the product. - Michael - San Bernardino, California

While there were many promising reviews, some customers weren’t too pleased with their results.

Guillermo said he experienced a rush similar to caffeine while using Nugenix. It made him feel very paranoid and got his heart pumping harder.   - Guillermo - Philadelphia, Pennsylvania

FAQs

Is Nugenix the Real Deal?

Although there is some talk that Nugenix is a scam, it isn't. But if you're still in doubt, it might help to know that the company has a friendly return policy and a 30-day money-back guarantee.

Customers can also easily cancel their subscription at any time and for any reason by contacting their support team via call or email.

Are There Side Effects to Nugenix?

There are side effects to taking Nugenix, such as pounding heart, upset stomach, trouble sleeping, blood clots in legs, and swollen feet or ankles.

To avoid these, follow the recommended dosage and consult your physician before taking this supplement.

How Long Does Nugenix Take To Work?

It could take anywhere from a few weeks to a month before you see results with Nugenix. But this may vary depending on your lifestyle and physical activity level.

For best results, the manufacturer recommends taking Nugenix for eight weeks combined with strength training.

Should You Buy Nugenix Testosterone Booster?

Nugenix is a great energy and stamina booster, but I wish it didn’t make me feel as agitated as it did during the first few weeks.

I also try to steer clear of products with a proprietary blend, but unfortunately, Nugenix is one of them.

However, Testofuel is a better alternative in this case.

I’ve personally tried this supplement, and it made a difference in my mood, energy, and body composition.

The company also provides 100% formula transparency, which many customers would appreciate.
