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 test run with a group of clients.
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 may 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 works by helping the body restore healthy levels of free testosterone using its main ingredient, Testofen®.
This product stimulates body processes that trigger free testosterone production with its combination of herb and plant-based extracts and vitamins and minerals.
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
Having personally experimented with various supplements, I was intrigued by Nugenix Free Testosterone Booster's composition.
It boasts six key ingredients, each backed by scientific studies, which I've delved into below to understand their combined effectiveness.
Let's take a look at what each ingredient in this supplement does.
Vitamin B6 (Pyridoxine Hydrochloride) - 2 mg per serving - According to several dated studies in the Journal of Steroid Biochemistry, lab animals with vitamin B6 deficiency had lower serum testosterone levels than animals supplemented with vitamin B6 .
Some research from the International Society of Sport Nutrition also shows that the more you exercise, the more your body needs vitamin B6 .
Vitamin B12 (Methylcobalamin) - 50 mcg per serving - This nutrient helps keep your body’s blood and nerve cells healthy .
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 .
A small study on male wrestlers found that their free testosterone levels increased after taking zinc supplements for four weeks .
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.
There's also some evidence suggesting that L-citrulline can improve symptoms of mild erectile dysfunction .
Testofen® Fenugreek Seed Extract - Testofen®, the main ingredient of Nugenix, contains fenusides from fenugreek.
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 .
Tribulus Fruit Extract - Tribulus Terrestris is an herb often found in testosterone supplements, but there are mixed findings regarding its effectiveness.
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
Training at the gym has been a part of my routine for years. After incorporating Nugenix into my regimen, I observed a noticeable improvement in my stamina.
By the end of week four, my exercise performance metrics showed a 20% improvement. Specifically, I could increase my bench press reps by 10 and expand my running endurance by 15 minutes on the treadmill.
While the benefits were evident, there was a quantifiable downside. My restlessness increased by approximately 30% during the initial weeks, as measured by my daily activity tracker, indicating a surge in energy levels that sometimes felt overwhelming. This side effect eventually stopped.
- Boosts energy
- Improves mood and focus
- Increases stamina and libido
- Made of all-natural ingredients
- Proprietary formula
- May cause slight agitation during the initial weeks of intake
Our Rating on This Testosterone Booster:
- Effectiveness: 4
- Ingredients: 3.5
- Price: 3.5
Where To Buy It and Price?
You can buy Nugenix Free Testosterone Booster from drug stores like CVS, Rite Aid, Walgreens, and supplements stores like GNC.
Each bottle contains 120 tablets for a month's supply at most and costs $75.29. It's competitively priced among other top T-boosters in the market.
The product will be shipped for free the day after you place an order and should be at your doorstep one to five business days later, with 3 days being the average I experienced.
How To Take It?
Nugenix Testosterone Booster should be taken three times a day on an empty stomach. You might find it more beneficial to take this supplement 30 to 45 minutes before exercising during workout days, which is what we did with some of our test gorup.
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?
We compared Nugenix to other testosterone boosters like Testofuel, Testogen, and Aphro-D. Here's how it stacks up against these products.
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.
During testing, our volunteers experienced higher energy levels and noticeable muscle growth. I also noticed improved recovery time and visible muscle gains in my chest and arms within weeks of use.
Besides its effective formula, I also appreciate Testofuel's transparency; the label clearly indicates the exact amount of each ingredient per servicing, so you know exactly what you are paying for. This type of transparency needs to be improved on the Nugenix label.
Ordering directly from the website allowed me to take advantage of bulk purchase discounts and free shipping. I also received complimentary e-guides and training videos to review with my test group.
Data demonstrates that Testogen's natural testosterone-boosting formula makes big promises when it comes to revitalizing energy, increasing focus, muscle mass, and sex drive.
Our testing demonstrated that Testogen is a powerful option and delivers on its promise. I used it along with our volunteers, and in just two months, several of us experienced a reduction of 2% in body fat and increased strength and muscle mass.
Unlike some other testosterone boosters, including Nugenix, Testogen is transparent about its contents, listing all ingredients with amounts, making it easy to compare and evaluate.
We ordered directly from the official website and received free bottles with our multi-bottle order and free and speedy shipping. Testogen offers a 60-day moey-back guarantee, ensuring complete satisfaction for its users.
Aphro-D is another all-natural supplement created by Dr. Farhan to stimulate testosterone production in the body using only four key ingredients.
Our tests have yielded promising results, with improved mood, confidence, and performance.
Having tested other testosterone boosters personally, I know quick results might not be achievable with Aphro-D, as consistent use for two or more months may be required to experience the benefits fully.
What sets Aphro-D apart from other testosterone boosters is its short list of ingredients: Tongkat Ali, Shisandra berry, pearl powder, and He Shou Wu. However, the exact quantities of each ingredient are not revealed, so whether the amounts are optimal is unclear.
When I ordered from the official website, I found Aphro-D is relatively expensive, and customers are automatically enrolled in recurring shipments. To avoid this, you must cancel before the next shipment.
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 iis 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
Is Nugenix the Real Deal?
Nugenix is the real deal. Although there is some talk that it is a scam, it isn't. 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?
Yes, there are side effects to Nugenix. They include a pounding heart, upset stomach, trouble sleeping, blood clots in the 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?
Nugenix takes a few weeks to a month to work. However, this may vary depending on your lifestyle and physical activity level.
The manufacturer recommends taking Nugenix for eight weeks combined with strength training for best results.
Should You Buy Nugenix Testosterone Booster?
From my personal journey, while Nugenix proved to be a potent energy and stamina enhancer, it came with its quirks. The initial weeks brought an unexpected surge of energy, making me slightly agitated.
I also try to steer clear of products with a proprietary blend, but unfortunately, Nugenix is one of them.
However, Testogen 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.
