Nugenix makes some pretty compelling claims, so we jumped into the ingredients of this testosterone-booster. To our surprise, it contains solid ingredients, but the price was an issue. Too many customer reviews pointing out the hefty price tag for our liking. We looked into the potential side effects of this product before finally tackling the scientific research. Well-researched ingredients may not be enough to overshadow the cost of this testosterone supplement. We shortened and summarized everything we found to bring you the bottom line on Nugenix.

What is Nugenix Testosterone Booster?

First off, Nugenix is a dietary supplement formulated to naturally and safely boost free testosterone levels.

The ingredients are:

The suggested use is three capsules per day on an empty stomach. The small bottle is easy to throw in your gym bag and take anywhere, which we like, but the price is out-of-this-world.

Nugenix testosterone booster is owned by Direct Digital; one of the leaders in the nutritional and wellness field. The supplement is sold through multiple retail outlets and local supplement stores. The price can get up to almost $80 on some sites – which is just ridiculous.

We felt you needed to know the facts, so we detailed all of the Nugenix ingredients.


Testofen is a branded form of fenugreek extract from Gencor. The seeds of the plant are used in the development of supplements. The leaves are commonly eaten as a vegetable in Indian countries. Claims suggest it can help with upset stomach, loss of appetite and erectile dysfunction. [1]

What is it Supposed to Do?

Fenugreek extract works in multiple ways to fight the symptoms of low testosterone. Research shows it can also positively affect body fat, strength, cholesterol levels and weight-loss. There’s also evidence it can work to “lower blood sugar levels after the meal in people with type 1 or type 2 diabetes,” according to WebMD.

Clinical Research

You’ll have no trouble finding fenugreek extract research. According to the brand website, there are also studies into Testofen. There is a brief description for each, but you have to request the complete study to be delivered via email. When we searched the author names, we did not immediately find any clinical titles.

A study in the Journal of the International Society of Sports Nutrition offers, “Based on the results of the study, we conclude that daily supplementation of 500 mg of the commercially available fenugreek supplement…in conjunction with an eight week, structured resistance training program can significantly increase upper- and lower-body strength, reduce body fat percentage, and thus improve overall body composition when compared to a placebo group.” It is important to note this study was completed on the Torabolic brand.

The European Journal of Clinical Pharmacology reports, “The repeated administration of a fenugreek seed extract specifically decreases dietary fat consumption in humans.”

In the Journal of Sports Science & Medicine, research showed, “In conclusion, combining 900 mg of a commercially available fenugreek extract with 3.5 grams of creatine for eight weeks in conjunction with a structured resistance training program can significantly impact strength and body composition in resistance trained males.”


Zinc is a metal considered an “essential trace element.” Only a small amount is needed by humans.

What is it Supposed to Do?

The most common use of zinc is to fight zinc deficiency. It has also been used for night blindness, diabetes, psoriasis, high blood pressure and peptic ulcers. It is the effect on erectile function and fertility that support use in testosterone boosters.

Clinical Research

The journal Nutrition reports, “Zinc supplementation of marginally zinc-deficient normal elderly men for six months resulted in an increase in serum testosterone…We conclude that zinc may play an important role in modulating serum testosterone levels in normal men.”

We also found mention of a positive effect of higher zinc levels in the journal Biological Element Trace Research. The study said, “Normal testosterone is associated with a higher Zn [zinc] level.”

Vitamin B6

Vitamin B6 is commonly found in foods like chicken, turkey, potatoes and some fruits. According to research, it can have a positive effect on heart disease, cancer, cognitive function, premenstrual syndrome and nausea in pregnancy. The uppermost limit for adults is 100mg a day.

Vitamin B12

Vitamin B12 is used by the body to promote overall nerve function and support the health of blood cells. The formation of genetic material and DNA in cells is associated with adequate levels. Though the vitamin is promoted as an energy booster, there is no research to back up these claims in people with normal levels.

We’ve heard the ramblings about testosterone boosters, like Nugenix, so we decided to dial into Nugenix ingredients. Our attention will turn to the formula, examining the science behind the product and the potential side effects; if any. Furthermore, we’ll concentrate on consumer comments. Then we’ll summarize the info to give you the bottom line.

What is Nugenix?

Nugenix is a testosterone booster, containing Testofen fenugreek extract, vitamin B6, vitamin B12 and zinc. The recommended serving is three capsules per day, which supposedly results in increased libido, strength, stamina and vitality. One positive is that you can take the supplement on-the-go.

Nugenix is a testosterone supplement that contains some natural ingredients and was introduced in 2001 by Direct Digital. The official website and trusted retailers sell the product. We like that the company has a long-standing history in the industry and that we found some positive customer comments, read on…

Blood Pressure Support – “A Surprise”

The first interesting thing we found in a review deals with blood pressure. Though there are no ingredients, that we noticed, that support a healthy BP, at least one customer has noticed the difference.

“After taking the product for about 2 1/2 weeks my blood pressure increased from 130/75 to 145/85,” said a user. This is another example of going a little overboard. An increase of this size could occur from anxiety, exercise and a plethora of other reasons; not specifically from a dietary supplement.

Effectiveness of Nugenix – “A Sure Thing?”

According to a few customer comments, Nugenix ingredients work as claimed. As one customer put it, “I have taken for 3 weeks and have seen a noticeable difference.”

Through our research and experience, we note that something small, like negative reviews, could reduce the chances of long-term success. If an happy Nugenix customer leaves a positive comment, that will play a big role in buyer trust.

The Science

Based on the available information on the official Nugenix website, the product helps maintain performance and drive in men. According to Phytotherapy Research, “Testofen demonstrated a significant positive effect on physiological aspects of libido and may assist to maintain normal healthy testosterone levels.” This is an amazing piece of support. [2]

The Bottom Line

We did the research on Nugenix ingredients and here’s our verdict. We like that the supplement contains a natural formula and that the company has been in business for years. The science is there, often multiple studies, and that’s what the customer is looking for.

If you want to increase energy and fight the symptoms of low testosterone, we suggest a product that’s backed by clinical support from a company willing to do the research and share these results.

A formula to enhance vitality and boost free testosterone could work hand-in-hand with Nugenix. One of the best supplements we encountered this year is one called Pronabolin. It’s made of a nine-ingredient proprietary blend, which has been shown to help improve energy levels, libido and test levels. We also love that customers are sharing some amazing testimonials.

Also, the company that makes Pronabolin is providing a multiple-bottle discount and 120-day money-back guarantee, an impressive sign of confidence in the supplement.

What You Should Know - Nugenix Facts

Nugenix is a natural testosterone boosting supplement. It helps with weight loss indirectly by helping to increase muscle mass. This increases metabolism and therefore the body’s own fat burning power. Unlike Winstrol, Nugenix is not a synthetic steroid and the ingredients are in pill form. If you are in the market for a testosterone booster, read this review to find out more about how it may be able to help you reach your goals.

List of Ingredients for Nugenix

Nugenix contains the following ingredients:
  • Testofen® which contains 50% Fenuside from Fenugreek
  • Zinc
  • Vitamin B6
  • Vitamin B12

Nugenix Product Features

Nugenix Ingredients form an all-natural testosterone boosting supplement. The proprietary formula includes Fenuside, which comes from fenugreek, a natural herb. It is a very popular ingredient among testosterone boosters. It helps increase testosterone levels in the body, by acting like the hormone, rather than increasing hormone production. Nugenix goes into more scientific detail on its official site. Women should not use this supplement because though there are small levels of testosterone in the body. The other ingredients in this formula are B vitamins and the essential mineral zinc, all of which are responsible for energy production and feelings of well being. These are popular ingredients found in products like Thyro Drive. Zinc and B vitamins are commonly found in multi vitamins, as well as in many food sources.



  • Nugenix is not a fat burner or an appetite suppressant.
  • This product isn't designed for women.

Conclusions on Nugenix

Nugenix looks like it's an ideal supplement for someone who is concerned about testosterone loss with age. However, we do like that this company has a nice BBB rating. If you are trying to lose weight, you should stick with a clinically proven safe and effective supplement in the form of an appetite suppressant or a fat burner. There are some products that attempt to tackle both like Marked Blast and Burn. For best results, the use of this supplement should be combined with a nutritionally balanced, only slightly reduced calorie diet, and a regular exercise routine comprised of both strength training and cardiovascular workouts.

    Can any body tell me what kind of effect Nugenix have on Prostate ?

    • Anna (Editor)

      Hello. When men suffer from prostate cancer, they are often given medications to nearly stop the production of testosterone.

      We don’t know of any direct effects Nugenix could have on prostate, however.

  • Steven Davis

    I only have one kidney due to kidney stone issues. Will this product hurt my only kidney???

  • Who is this for
    Amy Acosta

    Can women take this?

    • Anna (Editor)

      Hi! One of the main ingredients in Nugenix is Testofen. Research has shown a positive effect on libido in both men and women.

      But, the label says Nugenix should not be used by women.

    • Jimmy


  • Todd

    Had my T levels checked recently and they were 147 so my doctor ordered shots, started taking them but didn’t like the weekly injections. Would Nugenix be an appropriate substitute for injections?? I have high blood pressure and Epilepsy and have to take meds

    • Summer (Editor)

      Hi Todd. The simplest answer we can give you is no. The normal range for healthy testosterone levels is 280 to 1100. You’re not THAT far below the norm, but enough so that the doctor prescribed testosterone injections.

  • samuel rubio (Verified User)

    tried this product for 3 to 4 weeks. Did nothing for me. It made no differnce posative or negative.

  • Taking with Testosterone boosters

    Can a 58 year old man safely take these testosterone boosters?

    • Anna (Editor)

      Hi! Nugenix suggests anyone taking medications should ask their doctor before taking Nugenix testosterone booster.

      This is especially important if you’re already using testosterone replacements.

  • Blood pressure interactions

    Does this give you secondary effects like anger? And if safe to take is History of higher blood pressure ?

    • Anna (Editor)

      Hello. Many of the reports of anger we’ve read over the years have been linked to steroids or testosterone replacement therapy. We don’t hear mch about Nugenix an anger.

      As for the higher blood pressure – snap a picture of the label and stop by your doctor’s office. He’ll want to take a look first.

  • Probably Junk
    tommy gibbs

    The Tribulus study you linked to states “it doesn’t appear to increase male hormones (testosterone) in humans.”

  • Justin (Verified User)

    Just remember that you can buy all of the ingredients of nugenix separately for much cheaper. I bought separate bottles of all the ingredients (enough to last 2 months) for less than $20. It’s more pills to take but much better price. I’ve been taking it and have felt increased energy levels. I gave it 3 stars because I did have increased energy but the price is too high for an amalgamation of readily available over the counter supplements.

  • I want this product

    Would like to sample the nugenix

    • Yedy

      Hi Carla! Sorry, we don’t work with the Nugenix company.

    • Anna (Editor)

      Hi George. Problems reaching orgasm are not something we hear every day pertaining to Nugenix. If the condition continues or gets worse, you may want to head over to your doctor for a quick checkup.

Will it really work for me ? there are many other very affordable ED products out there with many testimonials about how fast and good they work. So tell me how fast and good Nugenix will work. Thanks

    • Anna (Editor)

      Hello Leonard. There’s no way of telling for certain how long it will take for you to feel the effects of Nugenix, if at all. The word directly from Nugenix is to use if for eight weeks with strength training for best results.

  • I was extremely depressed
    Ron (Verified User)

    I have taken Nugenix for about 3 years. I swear by it. When I was about 60 my testosterone levels had dropped to about 50T before I did anything about it. I was extremely depressed almost incapable of doing my job. I am a professional in an office responsible for about 150 clients.
    My first doctor gave me a T gel that I rubbed in. My second doctor began a testosterone injection regimen 200 mg every two weeks. Believe it or not that did return me to active sexual activity. It wasn’t until I started to take a similar product at GNC that put the hard back in an erection. After starting the injections I could get a limp erection but I could not perform. I could do my job and the injections put a swagger back into my step. Nugenix was the break over point for me. That is my experience without using any medical language.

    • Terry Moore

      I started taking Nugenix and I immediately got sick. The side effects are nasal congestion, cough and upset stomach. I got them all, I had to stop taking it so I could get well.
