Nugenix Free Testosterone Booster is a brand of supplements meant to help boost a natural production of free testosterone, the male sex hormone, in the body.
Direct Digital, LLC, is Nugenix’s parent company. Based in Charlotte, NC, they produces a variety of supplements, including Instaflex, Slim Science, and Luminite. Founded in 2009 by Brandon Adcock, Direct Digital does have an A+ rating with the Better Business Bureau and is accredited as of 2017, but we’ll take a look below about those details—because they’re both interesting and important. The contact number listed on the Direct Digital BBB profile comes up on a caller ID search as “Instaflex”—so, one of the brand subsidiaries. 
Nugenix itself claims to have researchers in Boston, but the only mailing address for Nugenix is in Salt Lake City, UT. Nugenix does not have a separate Better Business Bureau profile. Contact by phone is 1-855-714-3234, by email [email protected].
Nugenix Free Testosterone Booster can be found on the Nugenix website, or at several nutrition and drugstore websites and storefronts like Walgreens, Wal-Mart, GNC, and VitaminShoppe. Some offer their own auto-ship programs as well. Amazon.com even offers it through a third party. A 30-day supply (3 capsules once daily) ranges from $44 to $70, plus shipping in some cases.  
Nugenix Free Testosterone Booster Claims
The only claim on the Nugenix website itself is that this supplement “helps your body increase its free testosterone.” In the product FAQ section there’s a little more information in answer to the question of what the benefits of increased testosterone are: “Improved libido and sexual performance. Newfound vitality and passion.” 
Any further marketing is found on outside sites and on the box itself. From the Amazon.com sales page for Nugenix Free Testosterone Booster:
- Addresses the biological fact that by age thirty, most men will begin experiencing a gradual reduction in testosterone levels each passing year
- Helps restore testosterone levels within the body thanks to a proprietary blend comprised of Testofen, L-Citrulline Malate and Tribulus terrestris
- Testosterone plays a pivotal role in sexual performance, increased stamina and overall well-being
- And on the box pictured: “Libido – Performance – Drive – Vitality. Helps to: Feel Stronger – Increase Sex Drive – Boost Free Testosterone (all marked with asterisks leading to the standard not-FDA-evaluated disclaimer)”

The Science Behind Nugenix Free Testosterone Booster
According to WebMD, there are plenty of ways to boost testosterone levels, most having to do with eliminating the causes for level drop in the first place. Getting enough sleep, maintaining a healthy weight, staying active (but not madly active – turns out super-athletic levels of exercise can actually lower testosterone levels), managing stress, and checking medications with your doctor are all you really need to do. And while they don’t issue any strong warnings about testosterone boosters (specifically mentioning DHEA), they do suggest that most do little if anything.
But go to a bodybuilding site, and it’s a whole new story. Because testosterone boosters are touted as a muscle-builder and workout-recovery-speedup in addition to the vitality/libido mix, fitness sites have a lot to say on them.
But even they admit the science is still in the infant stages. One article on Bodybuilding.com mentions a number of ingredients that are in Nugenix Free Testosterone Booster as some of the top four recommended—the ones that actually have a little science behind them at the moment. Specifically mentioned are Tribulus terrestris and Fenugreek. 
The amount of Vitamin B12 in Nugenix Free Testosterone Booster is over eight hundred times the US RDA—and Methylcobalamin is the synthetic form of B12 best absorbed by the body. While there haven’t been any wide studies to indicate this is dangerous overall, it can be for men with specific health issues or who are taking certain medications, so you should always consult with your doctor before taking this or any other supplement.
Every supplement affects every individual differently. Gender, age, sometimes race, pre-existing medical conditions, and individual body chemistry—as unique as a fingerprint—can affect how a supplement works on you. That’s why supplements always add that “individual results may vary” disclaimer, and it’s why reviews for a drug or supplement can be all over the spectrum. Only you and your doctor can figure out how it works for you, so always be forthcoming and transparent with your doctor about side effects you experience, as well as if the substance doesn’t seem to be doing anything for you.
Word On The Street About Nugenix Free Testosterone Booster
The US Food and Drug Administration (FDA) does not regulate dietary supplements, only drugs. As such, supplement labels are prohibited from claiming any research-proven medical or health benefit—this is the function of a drug, in the FDA's view. The entire issue is convoluted, and there's no shortage of legal action brought against supplement manufacturers by the FDA and the Federal Trade Commission (FTC) on a regular basis.
Let’s look at that Better Business Bureau rating for a moment. In digging down a little, that rating is based mainly on how many resolved customer issues there have been. And Direct Digital has responded to all seven customer complaints (most folks don’t think to report a bad customer service experience to the BBB). The problem is, all seven were directly related to customer service issues when people bought through an infomercial site with a computerized ordering system and got signed up for the auto-ship when they were just looking for the “complimentary” bottle as a trial. Not a particularly great track record in terms of ease of communication, nor in making sure customers understand exactly what they’re being charged for. But all seven cases were resolved, eventually. (NOTE: there’s apparently some clause where if you report the issue to your credit card company first, Direct Digital can’t just give you a refund, as they have to see the investigation through first. Something to consider.) 
Now, customers. Going to Amazon.com, which tends to be brutally honest overall, Nugenix Free Testosterone Booster scored 3.5 out of 5 stars with almost 700 reviews. There were as many 1-star as there were 5-star, with the middle ground pretty evenly spaced as well. So hated it or loved it.
“Carl K.” said, “I’ve been using Nugenix for sometime now. I like the way it works. It fuels my workouts without the telltale caffeine boost. My wife likes the increase in the attention she gets.” 
“Robert” said, “I dont know about this product. Did nothing it claimed to do. Made my chest feel like it was going to explode. BP spiked to unsafe level. Stopped taking it, BP went back to normal.” 
The GNC.com site reviews showed a similar spread, though the 3-star middle ground was definitely the lowest. Again, either loved or hated. No one mentioned any really nasty side effects, but some customers did notice an increase in their blood pressure.
“Nuclearnews” said, “This is a completely ineffective product. I will go so far as to say it is an outright fraud. It delivered none of the stated benefits. It has a horrible odor and taste and upsets my stomach. I have canceled my monthly delivery program. I would not recommend this product to anyone.” 
“Ohrandyman” said, “I have been on low testosterone treatment by my physician for 3 years. This is my 4th month on Nugenix and after the second month started noticing an increase in activity levels and fewer problems with ED.” 
The Bottom Line
Is Nugenix Free Testosterone Booster worth a try?
Problematic.Pricey, sketchy reviews, sketchier company communication, and not a lot of real science at this point. Direct Digital isn’t offering a lot of consumer confidence with multiple contact points and negative-option auto-shipping (you HAVE to call them to cancel the auto-ship—you opt out, not in).
Based on the customer-to-company relationship, they have shown in a variety of ways that they do not want to disclose too much information, which makes me skeptical of the Nugenix line of supplements in general. You may be better off talking to your doctor about fenugreek and tribulus supplements individually.
