Nugenix Review

As men age, their testosterone levels drop. This is due to decreased production of the hormone in the body.

Testosterone levels peak during adolescence, then begin dwindling once you hit your 30s. For some men, this drop can start in their 20s.

Testosterone therapy is offered to boost testosterone levels in the body. However, the pharmaceutical drugs offered to address this issue comes with many side effects.

That’s why it’s a great idea to seek natural supplements that boost the production of testosterone in the body.

Nugenix is one such dietary supplement. Made of natural ingredients it helps raise the levels of total and free testosterone.

Does Nugenix work, and should you buy it? In this Nugenix review, I’ll tell everything you need to know about it before you hit the ‘order’ button.

I’ll also introduce you to TestoGen, another natural testosterone booster that can be a better alternative to Nugenix.

Nugenix Review

Brand Overview

Nugenix is a product of Adaptive Health, a company that manufactures various health-supporting supplements.

It’s a natural testosterone booster, which means that it only contains natural ingredients. This is unlike other boosters in the market that use artificial ingredients.

Nugenix is different from testosterone replacement therapy (TRT). In TRT, the levels of testosterone in the body are increased through injections, patches, or gels.

Boosting your levels through TRT can also present a lot of side effects, including breast enlargement, sleep apnea, and reduced sperm production. It can also increase your risk of developing heart or liver problems.

Nugenix, on the other hand, boosts testosterone by promoting its natural production in the body. It does not directly deliver testosterone to your body as prescription drugs do.

Because it doesn’t interfere with the natural production or balance of testosterone in the body, it doesn’t present the side effects common with TRT.

Besides boosting testosterone production, Nugenix also enhances energy levels and muscle building in the body. It contains a combination of ingredients that boost libido, vitality, and overall sexual function.

This is a supplement that’s meant to be used by men who have low testosterone levels. By helping increase the hormone’s production in the body, it also gets rid of the unpleasant effects of low T levels.



  • Includes ingredients with testosterone-boosting properties.
  • Boosts energy production in the body, making it easier for you to carry out physical activities and intense workouts without fatigue.
  • Promotes growth of lean muscle mass, which boosts strength and aids in fat loss.
  • Improves sex drive and overall sexual function.
  • Available for sale at the official website and from various online and physical retailers. This makes it easier to access from all around the United States or abroad.
  • It increases the levels of both total and free testosterone in the body. This ensures that there are increased levels of testosterone that your body can use for various functions.


  • It’s not suitable for use by men under the age of 18.
  • It’s not recommended for use with other drugs.
  • There are many negative reviews from past customers who claim to have experienced side effects such as nausea, headaches, and stomach issues after using Nugenix.
  • This supplement does not have effects on some men.
  • It contains a proprietary ingredient formula, where the exact dosages of certain ingredients used are not provided. This is inconvenient because it’s not clear how much of each ingredient is used, yet too high dosages can present various side effects.


Nugenix has 8 key ingredients that contribute to its function. These are carefully selected compounds that are aimed to aid with testosterone production, energy production, and muscle growth.

While not all of the ingredients present in Nugenix help with testosterone levels, they at least help with other areas of sexual function. These include blood flow and sexual desire.

Here are some of these ingredients and how they work:

Nugenix® Free Testosterone Complex 2103mg

This is the proprietary formula that’s found in Nugenix. The brand has only provided the overview dosage amount of all the constituent ingredients, which is 2103mg per serving.

This complex contains L-citrulline Malate, Testofen® fenugreek seed extract, and tribulus. Each of these contributes to men’s health in one way or another, including boosting testosterone levels.

The only downside about them is that as a user, you’ll not be able to tell how much of each is in every serving of Nugenix. This lack of transparency on the manufacturer’s side is not desirable, because:

  • Either they have used too little of the ingredients that could help with your T levels, which means you might not get any effects from using the product, or
  • They have included too much of the ingredients, which can result in side effects due to overconsumption.

Here’s what each of the ingredients in the proprietary formulations can do for you:

L-Citrulline Malate

L-citrulline Malate is a natural amino acid that can aid in reducing fatigue when taken as a supplement. In the body, it’s converted into another amino acid, arginine.

Arginine is used for the biosynthesis of nitric oxide. Nitric oxide dilates blood vessels, which eases blood flow.

This improves circulation within the muscles during exercise. With the increased supply of oxygen to the muscle tissues, more energy is produced.

Also, the tissues are well nourished to prevent quick fatigue and promote fast recovery. This ingredient is, therefore, useful if you maintain a regular exercise schedule.

The increased blood flow can also affect testosterone activity by increasing its availability to the cells and tissues. It can also help solve erectile dysfunction, which can be a result of inadequate blood circulation in your penile tissue.

Testofen® Fenugreek Seed Extract

This study shows that supplementation with fenugreek seed extract can increase both the total and free testosterone levels in men. Fenugreek seeds contain fenusides, chemicals that have been shown to increase energy levels, and boost muscle building.

Fenugreek seed extract also promotes muscle and strength, which makes it an important ingredient if you’re into bodybuilding. Finally, it has anti-diabetic qualities that can help control your blood sugar levels.


Last in the Nugenix® Complex is tribulus, an ingredient that you’re bound to find in almost every male sexual health supplement in the market.

The popularity of this ingredient is tied to claims that it can help boost testosterone levels in males. However, numerous scientific studies have proved that these are baseless claims with no evidence behind them.

A review of multiple studies revealed that in none of them did tribulus help in raising testosterone levels. However, this is not to mean that tribulus is useless in a testosterone-boosting supplement.

This study shows that tribulus can improve sexual dysfunction in men. It can increase your sex drive, solve mild to meditate erectile dysfunction and increase overall sexual satisfaction.

Other health benefits of tribulus is that it can lower blood cholesterol, decrease sugar levels, and protect against blood vessel damage.

All of these benefits will, however, be noticed if you use enough tribulus on a daily basis. The participants in the scientific study used between 750-1500mg of tribulus daily.

But since it’s not clear how much tribulus is in each serving of Nugenix, it’s difficult to tell whether you’ll truly benefit from these health effects.

Vitamin B12 50mcg

While vitamin B12 does not have a direct effect on testosterone production, it can help reduce some of the effects of low T. First, this nutrient has a major role in the production of red blood cells.

These are the cells that transport oxygen in the blood. When more oxygen is delivered to your muscles, there’s less incidence of fatigue.

Energy production is also boosted, which rids of weakness that you may be feeling due to dropping T levels.

Secondly, vitamin B12 supports bone health. This is important for you because low testosterone levels lead to the degradation of bones.

Lastly, vitamin B12 aids in the production of serotonin, a mood regulator. This hormone is capable of boosting mood and improving symptoms of depression.

In this way, the vitamin B12 in Nugenix can help raise your spirits and overcome the anxiety, low confidence, and depression that plague you due to low T levels.

Zinc 1mg

Low levels of zinc in the body usually translate to low levels of testosterone. This is why zinc supplementation is important for you.

Nugenix uses zinc chelate, which is easier to absorb in the body. This is since it’s bound to a chelating agent, a compound that creates a stable, water-soluble product when bound to metal ions.

In your body, zinc enhances fertility, sex desire, and long-term sexual health. It also ensures that your body maintains optimal thyroid function.

This is crucial because thyroid hormones stimulate the production of testosterone. So, aside from ensuring that your T levels don’t dwindle, zinc also helps to boost them.

Vitamin B6 2mg

Vitamin B6 is another nutrient in Nugenix that doesn’t directly affect testosterone levels but does help with other health aspects.

It’s involved in the breakdown of proteins to produce amino acids. Amino acids are then used in various body functions, including energy production and muscle building.

Vitamin B6 also keeps blood sugar at healthy levels and takes part in the synthesis of antibodies, hence boosting immunity.

Now that you know what’s contained in Nugenix, the next question is, does Nugenix work?

Nugenix Review

How Does Nugenix Work?

A look at several customer reviews on various platforms showed that Nugenix does work for some men. Through the activity of its ingredients, this supplement is able to:

  • Increase energy levels (this is the most mentioned benefit by many buyers).
  • Boost confidence.
  • Improve sexual performance and libido.
  • Enhance muscle building.

We can attribute this to the various ingredients in Nugenix that boost energy production in the body, raise testosterone levels, and combat mental health issues.

Fenugreek seed extract and zinc are the two ingredients that directly improve testosterone production. These are the ingredients that cater to Nugenix’s main aim, which is to increase both total and free T levels.

Total testosterone is the amount of the hormone that’s present in your bloodstream. However, not all of it is available for use.

It includes testosterone that has been bound to the proteins albumin and the sex hormone-binding globulin (SHBG).

The other type is free testosterone, which is not bound to anything and is therefore available for use. Testosterone that’s bound to albumin is loosely attached and can easily become bioavailable.

The testosterone bound to SHBG, on the other hand, is more firmly attached and cannot be used in cells or tissues.

By increasing your free testosterone levels, Nugenix allows you to enjoy the benefits of the hormone that include:

  • Increased muscle growth .
  • High energy levels in the body.
  • Improved libido, sexual stamina, and satisfaction.
  • Accelerated fat loss.
  • Better mental health with improved memory, focus, and reduced stress and anxiety.
  • More strength.
  • Increasing self confidence and motivation.
  • Better sleep quality.

How to Use Nugenix

You should take 3 capsules of Nugenix every morning on an empty stomach. 3 capsules are one serving, and each bottle contains 30 servings.

If you work out regularly, you should take the capsules 30-45 minutes before your workout session. This will maximize your energy gains and allow you to exercise harder for longer.

These capsules should be taken with water. If you find that they’re not working for you, it’s safe to increase the dosage by 1 or 2 capsules.

Side Effects of Using Nugenix

Nugenix is claimed to have no side effects due to its natural formula. And this is true for some users.

This supplement does not contain stimulants or banned substances that can cause extreme effects.

However, not all users enjoy zero side effects. A look at several customer reviews revealed that many customers deal with various side effects when using Nugenix.

Some of these may include:

  • Feeling nauseous.
  • Palpitations.
  • Headaches.
  • Lowered libido.
  • Stomach upset

There are also quite a number of reviews that mention a complete lack of effect. These users kept using the product for weeks and even months but did not experience any results.

For some, their low T symptoms worsened. This leaves several questions on how exactly Nugenix works since the number of dissatisfied customers is too high to ignore.

It appears that men who take part in resistance or strength training usually notice good results after using Nugenix. So, perhaps, you should only use this supplement if you can maintain a regular exercise routine.

Otherwise, you might not see any benefits, and you’ll be susceptible to the side effects.

Where to Buy Nugenix, Prices, and Guarantees

You can buy Nugenix on the official website. This supplement is also available at various retail stores, including GNC, Walgreens, Drugstore.com, Rite Aid, and Vitamin World.

On the official website, each bottle goes for $69.99. 2 bottles go for $139.98, and 3 for 209.97.

This means that no matter how many bottles you buy, you’ll still pay the same unit price. Most customers find this supplement to be quite expensive compared to others in the market.

Others complain that the price is not worth the effects provided by Nugenix. In my research, I found that there are several testosterone boosters in the market with more powerful ingredients that cost much less than Nugenix.

Nugenix has a 30-day money-back guarantee, which pales in comparison to guarantees offered by other brands.

A single month is not nearly enough to gauge whether a testosterone booster is working effectively. Also, this 30-day period begins from the day when the product is shipped to you, which is inconvenient.

If the product takes a week to get to you, it means that you only have 21 days to observe its effects. With other boosters offering 60 or 100-day guarantees, Nugenix is riskier to try.

Nugenix Alternative

If you don’t wish to risk the side effects, spend too much on a supplement, or get a guarantee that doesn’t really help you, you should look at a better Nugenix alternative.

I found TestoGen, a natural testosterone booster with a total of 11 ingredients. The best part about these ingredients is that they’re all backed by science to improve male sexual function.

Testogen claims to improve testosterone levels, boost muscle growth, and reverse libido. It’s a product to go for if you want to improve your physical and sexual performance.

Best Testosterone Booster Testogen

Here’s a quick look at what makes TestoGen a great alternative to Nugenix:


  • It contains natural ingredients, proven through scientific research to be beneficial to men’s sexual health.
  • Most of the reviews by customers are positive, with many users noting increased energy levels, better focus, and fat loss.
  • It comes with a 100-day money-back guarantee, which gives you enough time to decide whether it works or not. This is much better than Nugenix’s 30-day guarantee.
  • Free worldwide shipping is offered on all orders. When you buy Nugenix from the official website, you’ll pay a $4.99 shipping cost for a single bottle, and the amount may increase depending on how much you buy.
  • When you bulk buy TestoGen, you’ll enjoy massive discounts. One bottle goes for $59.99, three for $119.99, and 5 for $179.99. It’s not only much cheaper than Nugenix but also allows you to save a lot of money when you buy more.


While TestoGen is a better alternative to Nugenix, it also has its downsides. But, these are not as inconvenient as those we’ve seen in the Nugenix review.

  • A single serving of TestoGen is 4 capsules, which can be a bit of a hassle to take at once each time.
  • It might produce side effects when used alongside prescription drugs.

Testogen Ingredients

The power of TestoGen comes from its formulation. These are the ingredients in TestoGen:

  • D-Aspartic Acid
  • Vitamins D3, K1, and B6
  • Zinc and Magnesium
  • Fenugreek Extract
  • Nettle Leaf Extract
  • Bioperine
  • Boron
  • Korean Red Ginseng

Each serving of TestoGen contains 2352mgs of D-Aspartic Acid, an amino acid that’s very crucial for testosterone production.

It increases the secretion of the luteinizing hormone, which in turn binds to Leydig cells in the testes. Through this, they facilitate the release of testosterone from the cells into the bloodstream.

With proper supplementation, D-Aspartic Acid can increase testosterone production by almost 50% in a matter of weeks.

Magnesium is the other ingredient in TestoGen that directly influences testosterone levels. This study shows that supplementation with magnesium can increase free and total testosterone levels in people who exercise and in those who don’t.

Lastly, let’s look at nettle leaf extract, which is essential in increasing the levels of free testosterone in the body. It binds to SHBG, which prevents testosterone from doing the same.

This leads to more free testosterone in the bloodstream that’s available for muscle building, sexual performance, and other functions.

Where to Buy TestoGen

TestoGen is available for sale on their official website – clicking on the button above will take you there. When you buy here, you’ll pay affordable prices, as I’ve already mentioned.

There are also discounts on bulk buying, discount codes that you can use to make further savings, and free worldwide shipping.

Conclusion: Should You Buy Nugenix?

Reviews from Nugenix customers are, at best, mixed. If you don’t take part in regular physical activity, this product might not work well for you.

You might also be susceptible to several side effects, which have affected many users. Then there’s the expensive pricing with no discounts.

If you buy Nugenix, you’ll have less than 30 days to get a refund if it doesn’t work. I think it’s a great idea to buy just a single bottle the first time so that if you’re unable to get a refund, you’ll not have lost much.

After weighing the pros and cons of both Nugenix and TestoGen, the latter could be a better option for you. It improves testosterone in multiple ways, uses ingredients that are backed by science, and is a lot cheaper.

Then there’s the 100-day money-back guarantee that gives you more than enough time to decide whether the product is working for you or not.
