Nugenix is a testosterone booster that has been marketed to help men boost their levels of this hormone. The product promises to increase muscle mass, strength, and endurance. This review will focus on the dietitian’s objective analysis of the supplement. Read more in detail here: nugenix reviews side effects.


  • Most big shops carry it.
  • Return policy is 30 days.
  • Ingredients that are relatively safe


  • Expensive
  • There isn’t any independent third-party testing.
  • There is no information on the amount of each element in the testosterone complex.


The testosterone boosting chemical mix in Nugenix Free Testosterone Booster is intended to promote healthy testosterone levels.

Men will gain more muscle with strength training, have higher strength, and improved sexual drive and performance, according to testosterone boosting pills like Nugenix.

The principal male reproductive hormone, testosterone, serves a variety of activities in the body, including sexual function, reproduction, skin health, energy, mood, and brain health.

It also helps to manage fat metabolism and muscle mass, which is important for body composition.

As men become older, their testosterone levels gradually decline, generally starting around the age of 30.

Erectile dysfunction and an increased risk of major illnesses such as diabetes, heart disease, obesity, and depression have been related to low testosterone levels.

Since they’re regarded safer than hormone replacement treatment, over-the-counter testosterone boosters have grown in favor.

Blood tests are the only method for a guy to find out whether his testosterone levels are low.

I believe that many guys use these “natural” testosterone pills to improve their outcomes in the gym and in the bedroom without having to go to the doctor.


Ingredients Evaluation

According to the Nugenix website, their Free Testosterone Booster is made up of eight substances that have been “lab tested for optimal efficiency.”

Surprisingly, there are just six ingredients listed on the supplement information label.

Only if they include the two inactive components, gelatin and magnesium stearate, which are just capsule ingredients, does this product have eight ingredients.

This error made me skeptical of the product promises, but we’ll have to wait and see what the research shows.

B6 is a B-complex vitamin (pyridoxine hydrochloride)

Each dosage of Nugenix Free Testosterone Booster includes 2 milligrams of vitamin B6.

B6 has a Recommended Dietary Allowance of 1.3 milligrams per day and a Daily Maximum Allowance of 100 milligrams.

Vitamin B6 is essential for energy generation and protein synthesis.

Most individuals don’t require B6 supplements since they receive enough from diet, which includes chicken, pork, seafood, white and sweet potatoes, and a variety of fruits.

I couldn’t discover much evidence of a link between vitamin B6 and testosterone, although some research from the past revealed that lab animals with B6 deficiency had lower testosterone levels than animals given vitamin B6 supplementation.

According to several studies, exercise increases the demand for vitamin B6.

B6 is a “energizing” vitamin, thus I’m guessing Nugenix contains it.

B12 (cobalamin) (methylcobalamin)

Each dosage of Nugenix Free Testosterone Booster includes 50 mcg of vitamin B12.

B12 has a Recommended Dietary Allowance of 2.4 micrograms per day, with no Upper Limit since toxicity is rare.

The majority of individuals acquire adequate vitamin B12 through their diet, which is abundant in animal foods such as meat, poultry, fish, eggs, and dairy.

Vegans and certain vegetarians who do not consume animal products may need to take supplements.

Vitamin B12 is required for cell development, which includes the formation of new red blood cells.

There is no relationship between testosterone production and vitamin B12.

Even though there is no evidence to suggest this if your levels are normal, several energizing products contain it to boost energy and athletic performance.

Zinc is a mineral that may be found in (zinc chelate)

Each dose of Nugenix Free Testosterone Booster includes 1 mg of zinc.

Zinc has a Recommended Dietary Allowance of 11 milligrams per day and a Daily Upper Limit of 40 milligrams.

According to a review of data on zinc’s function in physical activity, blood zinc levels drop after exercise, indicating that it aids muscle repair.

There’s also some evidence that there’s a link between zinc levels and free testosterone levels in the body.

After four weeks of zinc supplementation, levels of free testosterone in male wrestlers rose, according to a small research.

Free Testosterone Complex by Nugenix

The main ingredient in Nugenix Free Testosterone Booster is Free Testosterone Complex by Nugenix, which contains Malate of L-citrulline, Testofen, and tribulus.

The label claims that each meal includes 2,103 mg of this complex, but it doesn’t specify how much of each component is in each serving.

Malate of L-citrulline

Malate of L-citrulline is an amino acid. In the body, it’s converted to another amino acid, L-arginine, which is involved in the production of nitric oxide.

By dilating blood arteries, nitric oxide aids in healthy blood flow.

Nitric oxide deficiency has been associated to erectile dysfunction (ED).

Some research shows that L-citrulline supplementation might help men with moderate ED symptoms.

Supplementing with L-citrulline did not improve performance in high-intensity plyometrics, upper-body strength training, or cycling, according to a number of trials.


Fenugreek seed extract is sold under the brand name Testofen. Fenugreek is a plant that has been used in cooking and traditional medicine for thousands of years.

Fenugreek seed extract has been shown to boost testosterone levels, libido, and body composition in males.

Males ingesting 600 milligrams of fenugreek seed extract per day for 12 weeks had improved sexual function and testosterone compared to the placebo group, according to this double-blind, randomized controlled experiment including 120 men.

Another research of 60 males revealed that those who took 600 mg of Testofen per day had better libido than those who received a placebo.

In a study of 49 males, those who took 500 milligrams of fenugreek seed extract for 8 weeks showed increased body composition and strength compared to those who took a placebo.


Tribulus has also been used in traditional medicine.

Even though studies on its effectiveness is conflicting, it’s often used in testosterone-boosting pills.

Tribulus supplementation has been shown in many trials to have no impact on testosterone levels or erectile dysfunction, however it may boost libido.

There’s also no proof that it helps athletes improve their performance or body composition.

Safety, Dosage, and Side Effects

Nugenix Free Testosterone Booster is intended to be taken three times a day on an empty stomach.

The supplement should be taken in the morning or 30–45 minutes before an exercise, according to the directions.

The firm recommends taking Nugenix for 8 weeks in conjunction with exercise, according to the product FAQ website.

They also give a recommendation for guys who need a higher dose of testosterone booster than what is suggested.

According to the website, raising the dose from three to four or five capsules is fine since it “will still be within a safe tolerance zone.”

Supplement producers should not give customers a free pass to raise the suggested dose as they see appropriate, in my opinion.

How can someone tell if they aren’t receiving enough?

Supplements that indicate a “complex” on the ingredient label but don’t specify the actual quantity of each component make me nervous.

Although the chemicals in Nugenix Free Testosterone Booster are likely to be safe for most healthy men to consume without causing major side effects, not knowing the precise dosage of the active ingredient might cause some issues.

While using this supplement, some people may suffer moderate stomach distress.

This product also includes a considerable quantity of vitamin B12, which isn’t dangerous but seems unnecessary.

If you’re taking additional supplements that include vitamin B12, such as a multivitamin or a pre-workout, you could be receiving too much.

Although Nugenix doesn’t have nearly as much vitamin B6 or zinc as other supplements, you should examine the amounts in other supplements to be sure you’re not receiving too much of these nutrients.

Although it’s unlikely that this supplement can cause you to produce too much testosterone, it’s still a good idea to be aware of the indicators that your testosterone levels are too high.

Too much testosterone may cause acne, voice changes, excessive body hair, male pattern baldness, and mood swings.

If you see any of these changes, make an appointment with your primary care physician right once. 

If you’re interested in using this or any other testosterone booster, talk to your doctor first. 

Where to Buy and How Much

Nugenix is available at most major shops, including drugstores such as Walgreens, Rite Aid, and CVS, as well as supplement stores such as GNC.

One bottle of Nugenix Free Testosterone Booster costs $69.99. Each container includes 90 capsules for a 30-day supply, equating to $2.30 per serving each day.

It’s simply too pricey for a single supplement, in my view.

Nugenix does back its product with a Return policy is 30 days..

Their contact details and return information are available on their website.

How Does Nugenix Free Testosterone Booster Measure Up to the Competition?

The majority of testosterone boosters for males are made up of unique combinations of herbal components, vitamins, and minerals.

Zinc, fenugreek, vitamin B6, tribulus, magnesium, boron, and maca are all common constituents. The majority of them are in the $20 range for a one-month supply.

Most testosterone-boosting pills, according to this study, lack proof to back up their claims, and many of them include high quantities of vitamins and minerals that may quickly approach or surpass upper limits when mixed with other supplements.

Final Thoughts

Research suggests two of the ingredients in Nugenix Free Testosterone Booster, Malate of L-citrulline and fenugreek seed extract, may help improve sexual function, libido, and body composition.

The data, on the other hand, is limited and shows only short-term effects.

There is no proof that using this product will provide long-term benefits.

A Message from Our RD

If you think your testosterone needs a boost, there are a few lifestyle changes you may do to assist.

Natural testosterone boosters, predictably, follow the same basic guidelines for optimal overall health.

Men who are physically active, keep a healthy weight, and consume a nutritious diet have greater testosterone levels than those who are not.

Other lifestyle choices that contribute to maintaining healthy hormone levels include not smoking, limiting alcohol use, and getting enough sleep. 

If you’ve already selected those boxes, I suggest seeing your primary care physician before using this or any other testosterone booster.

They can test your hormone levels, which is the only method to tell whether you have low testosterone for sure.
