“A little pricey, however how do you put a price on the results I’m receiving,” commented a customer.

“Still think it’s a little on the pricey side, but will…order more,” reported another.

One user said, “Definitely worth the price.”

“This is the real deal. As for the price I don’t mind at all because it works,” stated another.

Positive Feedback About Nugenix – “Things Look Good!”

When it comes to a natural supplement or even a prescription medication, there is a time-frame the user needs to wait through to see the full effect of any formula. Users with the patience to hold on, saw good results with Nugenix. [3]

“The product takes extra time to work,” said a user.

“Decided to give Nugenix a try. After 4 weeks, I noticed an increase in drive and after 6 weeks, I noticed better results from my usual weight training,” commented a customer.

One said, “After being on it for 8 days now, I have noticed a small weight gain [and] a slight energy increase.”

“Tried this product…felt strong at the gym,” reported a customer.

We’ve found in our research that if some users don’t see the immediate results they’re looking for, they won’t stick around long enough to see the lasting results. When it comes to Nugenix, the results are there, and the ingredients are solid.

The Science – “Following Research”

We examined the Nugenix website and found a wealth of information relating to improving free testosterone levels. There are many factors to consider, including age, fitness level and diet.

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.

Nugenix Side Effects:

From time to time, there are supplements that need additional attention, like Nugenix, so in our review we concentrate solely on Nugenix side effects. We took a deep dive into the ingredients and scientific research. We also read hundreds of user comments. Then we gathered the info you need to give you the bottom line.

What is Nugenix?

Nugenix is a testosterone booster containing Testofen (fenugreek) and B-vitamins. According to the packaging, you take one capsule, three times per day. It supposedly “boosts free test.” You take it multiples times so the small bottle is a plus.

The supplement was introduced as a testosterone booster in 2009 by Direct Digital and contains some natural ingredients. Nugenix is available to buy on the official website and through various retailers. We like that the company has a favorable BBB rating and we located some positive customer comments, but read on…

Solid Results from Nugenix

The first thing we found, and couldn’t miss, were the reports of solid results from Nugenix ingredients. “There are many out there who worry about side effects,” shares our Research Editor. “This time, we found positive reviews and some good testimonials.”

A customer offered, “I’ve noticed increased energy, drive and muscle tone (with exercise :0)”

“There was…a noticeable difference in my energy level, metabolism, muscle tone,” another reported.

Decreased Blood Pressure – “Interesting”

What’s interesting is that some users noticed a better blood pressure reading after starting Nugenix. One review said, “I do not know if it affects blood pressure but my top number has decreased by 14 points.”

We found no scientific reason for this to happen, but we found more than a few comments just like this. If you are taking Nugenix and working out, while following a healthy lifestyle, there’s a chance for all kinds of health improvements.

Based upon our research, it may take only one thing to offset chances of long-term success. With the Nugenix formula, we’re impressed by the solid formula and strong customer support.

The Science

We scoured the official Nugenix website and it provides a wealth of information. There is some proof fenugreek extract works and Testofen has been tested more than a few times. At DietSpotlight, we deal in science to back product claims. It’s that little extra work that means all the difference.

The Bottom Line

After careful consideration about Nugenix, here’s our verdict. The company has a positive BBB rating and we found some good customer comments. We like that the company is trusted and there are some solid ingredients in the formula. It looks like this is a solid choice all around.

If you want to boost testosterone levels, increase energy and spark libido, we recommend a supplement that’s supported by published clinical research.

You may want to add a vitality booster and free testosterone support to Nugenix. Pronabolin is among the best supplements we’ve seen in 2016. The formula contains a nine-ingredient proprietary blend, which has been shown in studies to help support test production, strength and muscle recovery. Plus, the customer reviews are amazing.

Also, the company behind Pronabolin, as a sign of confidence, is offering a multiple-bottle discount and 120-day money-back guarantee.

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 in 2016 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.

Andre R

I started taking Nugenix three months ago. It works for me. At 49 I noticed my mood changed, always tired, feeling like a nutered cat. It took two months for Nugenix to kick in. No complaints here.


Does this medication affects blood pressure?


I am 59 years old and started working out on a regular basis last December by swimming 3 times per week. I just started taking Nugenix about 10 days ago. I have noticed that my endurance in the pool has increased and I am finishing my workouts feeling stronger. I have also noticed that my sex drive has increased dramatically. I have never suffered from ED but my erections weren’t what they were at 40 either. My wife has noticed a big difference! I am a believer in Nugenix!
