Nugenix Review - Can It Help Boost Your Testosterone Levels?

What is Nugenix Free Testosterone Booster?

Nugenix Free Testosterone Booster is a dietary supplement that is alleged to boost free testosterone (T) booster through a blend of natural ingredients.

Testosterone is a steroid hormone that wears many hats. It plays a role in supporting lean muscle mass, bone density, heart health, carbohydrate metabolism, mood, in addition to maintaining sexual health.

A decline in T levels commonly occurs around the age of 40 even in healthy individuals, though disease and other health-related conditions can be associated as well.

As T offers so many benefits, deficiency may lead to many unwanted effects like:

  • Fatigue
  • Mood changes
  • Erectile dysfunction
  • Low libido
  • Decreased bone density
  • Diminished muscle mass
  • Increased body fat and

Most of your T is bound to circulating proteins, but it is unbound, free testosterone that is largely responsible for the many health benefits.

Nugenix Free Testosterone Booster is alleged to boost free T by taking just 3-capsules per day. In fact, the company claims that Nugenix will help you feel stronger and increase sex drive.

In this article, we’ll help you determine if there is any merit to these claims by reviewing the available scientific support for the Nugenix blend of ingredients.

The Active Ingredients: Do They Work?

Nugenix Free Testosterone Booster is alleged to elevate your T with the following ingredients:

  • Vitamin B-6 - 2mg
  • Vitamin B-12 - 50mcg
  • Zinc - mg
  • Nugenix Free Testosterone Complex - 2,103mg
    • L-Citrulline Malate,
    • Fenugreek Seed Extract
    • Tribulus

Vitamin B6 and Vitamin B12

B6 may support a number of health benefits, though they are often added to supplements that claim to boost T levels as it is suspected to enhance the proposed effects of zinc.

Vitamin B6 inhibited 5-alpha reductase activity, the enzyme that converts testosterone to dihydrotestosterone (DHT) in a rat study. The rationale is that limiting this enzyme can prevent drops in T.

This benefit was also seen in a laboratory study; vitamin B6 boosted zinc’s ability to limit the conversion of T to DHT.

Adding 11mg of vitamin B6 to 30mg of zinc did not enhance muscle endurance, body composition, or T levels.

B12 may play a role in enhancing sperm quality. It improved sperm motility and sperm count in 26 infertile males, though testosterone was not increased.

B6 and B12 may play a role in boosting T and supporting sexual health, though much more research is needed to identify clinical use.

Zinc

Zinc is an essential mineral that may limit the activity of 5-alpha reductase. As described above, ot is often paired with B6 to enhance its effects.

Zinc deficiency was associated with decreased T levels in healthy men, and supplementation elevated levels.

These results were not confirmed in later studies.

Zinc did not improve muscle endurance, body composition, or T levels in healthy subjects treated with 30mg daily for 2-months. Thus, even with doses much larger than that of Nugenix, benefits were not seen.

While laboratory studies have highlighted a potential role for zinc, this relationship has not been well supported in human studies.

L-Citrulline Malate

L-Citrulline is a non-essential amino acid that may increase exercise performance, support recovery, and improve erections in those with mild to moderate erectile dysfunction (ED).

These effects may be related to L-Citrulline's ability to increase blood flow through enhanced nitric oxide formation. Taking 1.5g per day was associated with improved erection hardness and increased intercourse frequency.

Still, more studies are needed to demonstrate these effects in the long-term.

Fenugreek Extract (Testofen®)

This herb may also work to prevent the conversion of testosterone to DHT.

At 500mg doses, fenugreek significantly improved body fat composition and testosterone levels in 30 healthy men over the course of 2-months.

Another trial found that 600mg of fenugreek over 6-weeks experienced improvements in libido and other sexual health parameters when compared to placebo.

The results of these studies are promising, though limited. More long-term research is needed to fully characterize the benefit of this supplement.

Tribulus

Tribulus is a plant-based extract that may offer various sexual health benefits. The research investigating these proposed effects has been mainly in animal models, however.

A review of 11 studies concluded that tribulus boosted T levels in some animal studies. Benefits were seen in human studies only when tribulus was part of a supplement blend.

In rugby athletes, 450mg of tribulus daily over 5-weeks did not benefit strength, lean muscle mass, or T levels. Men with erectile dysfunction that took 6g of tribulus twice daily for 60-days boosted their T levels and experienced improved sexual health.

Though tribulus may play a role in elevating T levels, support for this role in human studies is lacking.

The Takeaway Message

While some of these ingredients offer some potential benefits for elevating T and supporting sexual health, Nugenix only provides dosing for the total blend. Thus, we don’t know how much L-citrulline, Fenugreek, or Tribulus it contains.

Without this information, we can’t determine if there is enough present to see results seen in research studies.

Nonetheless, most of the support is limited, mixed, or found mainly in laboratory and animal studies. Much more research is needed to identify the long-term benefits in humans.

Is Nugenix Free Testosterone Booster Safe?

Nugenix Free Testosterone Booster contains a blend of natural ingredients that are often found in supplements that claim to boost T.

B vitamins are excreted in urine when consumed in excess. Serious side effects are rare, though symptoms can include nausea, vomiting, and skin flushing.

Zinc was safe in doses of more than 30x those included in Nugenix. The upper intake limit is also well beyond the Nugenix dose. Side effects are typically mild and relate mainly to digestive issues.

Serious side effects were not reported in research examining the effects of fenugreek and tribulus, though mild digestive symptoms may occur.

While there is no evidence that these ingredients can boost T into dangerous ranges, you should be aware of the signs that your T may be too high. These can include:

  • Facial and body acne
  • Voice changes
  • Excess body hair/ male pattern baldness
  • Mood fluctuation

As the delicate interplay of multiple symptoms achieves hormone balance, managing them on your own can be risky. Speak to your doctor first, especially if you’re experiencing symptoms related to low T.

What Does It Cost?

Nugenix Free Testosterone Booster is available directly from the Nugenix website.

It costs $69.99 + $4.99 shipping per bottle; at 90 capsules, this will last you one month when used as directed. Nugenix backs your purchase with a 30-day satisfaction guarantee.

To process your refund, contact support at 1-855-714-3234 or support@nugenix.com.

You can also find the 90-count bottle at Amazon for $49.69. As Amazon similarly offers 30-day returns, this is a more cost-effective option.

What Are the Alternatives to Nugenix Free Testosterone Booster?

The Nugenix Free Testosterone Booster blend is not unique. In fact, these ingredients are commonly included in supplements that claim to increase T.

Nugenix Total T is another product offered by this company. It contains an identical blend, though it also includes a couple of extra extracts, as well as Boron. While you may get a bit more, pricing is identical.

EVLTest Testosterone Support Complex offers a 1-month supply for $34.99. Like Nugenix, they also offer B6, zinc, tribulus, and fenugreek. You’ll miss out on L-citrulline, though they also include D3, magnesium, D-aspartic acid, and DIM.

Given the similarities in the blend, EVLTest is probably a more cost-effective option. Keep in mind, the research supporting most of these ingredients is lacking.

You can also try boosting T through diet. Some foods that may elevate levels are fish, chicken, and eggs. If you opt for a vegan or vegetarian lifestyle, you can try leafy green vegetables, seeds, and nuts.

Regardless of which option you’re interested in, always speak to your doctor first to identify the cause of your symptoms.

Pros and Cons

Pros
  • Some of the ingredients have support for boosting T and supporting sexual health, though the available studies are limited and offer only short-term results
Cons
  • Expensive compared to other available supplements with similar blends
  • Strong support for the actions of most ingredients are lacking
  • Managing hormone levels without medical supervision can be dangerous

The Bottom Line

Nugenix Free Testosterone Booster contains common ingredients that are suspected of boosting T, though strong support for most of them is lacking.

While some studies highlight a potential role for this blend, more research is needed to determine the long-term safety and efficacy.

Though generally safe to use, you should avoid managing hormone levels on your own. Speak with your doctor if you are experiencing symptoms that may be related to low levels of T.

Given that the research is not robust, the supplement is expensive, and the need for medical guidance for hormone-related issues, you should avoid using Nugenix Free Testosterone Booster before speaking with your doctor.

  • Fraudulently charging for product not received!

    • By Doug Parmer,

    This outfit is a complete rip-off. After less than one month the company charged my bank account over $74.00 for a product that we never received. When I called, I was told that I clicked on some area that spells out the terms and conditions of their charges and was refused a refund. This is odd because I did NOT order the product online, I ordered it via a text message. I hung up on the first uncooperative rep (Operator 303 - very rude person!) and I called back. After sitting on hold for several minutes, the rep came back on the phone and told me his supervisor gave the okay for an immediate refund. We shall see if the product ever arrives (you can bet it will be returned) and we shall see if we are issued that refund.

    It is beyond unethical to charge for something that you never receive and further be charged when I never approved those charges or any future orders. Again it was ordered via text message and not in a website with click thru capability.

    I will be reporting this as a fraudulent transaction on Nugenix's part and will be posting to every website I can to warn people to STAY AWAY from this company! I am extremely angry and upset that anybody can randomly take my checking account information and charge over $74.00 for a product that was never received!

    Buyer beware. I had to rate it as one star because there is no zero stars option. Otherwise, the rating would be a zero.

    Bottom Line: No, I would not recommend this to a friend


  • Don't do it!

    Total scam. Recurring billing is IMPOSSIBLE to cancel unless you fight with customer service. It is an MLM out of Utah (surprise!). Drink a RedBull and be better off, both in money and other ways as well.

    Bottom Line: No, I would not recommend this to a friend

    This company and product is a complete scam. I should have known better than to buy into this scam. The product doesn't work at all. It is a bait and switch to get you in the door. They make you pay shipping to return the product that you didn't order in the first place.

    Bottom Line: No, I would not recommend this to a friend

    I tried Nugenix two years ago before it became popular. I was on it for three months consecutive, and it did absolutely nothing. I used to use pink magic until the company discontinued it. Nugenix did NOTHING. Not even a placebo effect. Don't waste a penny on that crap.

    Bottom Line: No, I would not recommend this to a friend


  • Save your money

    • By D P W.,

    I bought Nugenix to boost my testosterone. Having turned 60 I was looking for a little boost in my sex life. I was told by the expert at GNC that this was the ticket. And that I would see noticeable results within 14 days.

    So I took them as directed for a whole month with absolutely no benefit at all. So, like the average dummy, I thought well, maybe I need to keep trying it. So I bought another bottle and nothing. So I bought a third bottle and added to it all the dietary restrictions and enhanced foods, and still nothing. Then I spoke with my doctor and he informed me that a lot of people were experiencing bone mass problems and that he would suggest me not taking them anymore. And gave me a prescription for generic viagra, and that did the trick.

    So I would definitely recommend that you save your money. This product is a dead firecracker with a lot of hype, but it does absolutely nothing. Save your money.

    Bottom Line: No, I would not recommend this to a friend


  • Did NOTHING!

    It did nothing for my man. Absolutely nothing! Just like weight loss pills and wrinkle cream, it's a scam. Don't waste your money! A lot of money for nothing. He took it religiously as indicated on the bottle. Honestly, I don't think he needed it, but he's older than me and worries. He said he couldn't tell a difference, and neither could I. Don't waste your money.

    Bottom Line: No, I would not recommend this to a friend


  • Bad stuff

    I got a free bottle. I only took two, it made me act totally different than I am. I don't know what's in this, a steroid or what, but it gave me extreme moods, anger, irritability, and I felt violent. Any more of this and I may have hurt someone. I didn't check with the doctor either, she was very upset and said I should never take male boosters.

    Bottom Line: Yes, I would recommend this to a friend

    This product did NOTHING for me; in fact, I felt the opposite of what they claimed it would do. Also, the 30-day money back guarantee is a farce. The salespeople also tell you to give it a month and a half to work, thus throwing you out of the refund period.

    Bottom Line: No, I would not recommend this to a friend


  • Scam

    • By Dusty P.,
    • Iowa,

    • Verified Reviewer

    Poor quality. I was charged $75 after buying the sample and was charged $34 overdraft fee. I knew nothing about this but they charged me, and I am supposed to send their second product back, which I never received, to get my money back. The person I talked to had a hard time speaking and was rude when asking me a question, she would cut me off each time I tried to answer her.

    As for the product, if you can stand how horrible it tastes, you will get a bad stomach ache and won't be hungry while feeling like your insides are dissolving. The powder in the pills is all over the pills, like half pills and half powder. I'm telling you, the taste is so bad and lingers all day, so you won't be taking these long enough to finish their sample. I'm out close to $100 and nothing to show for it.

    Bottom Line: No, I would not recommend this to a friend


  • Don't waste your money on Nugenix

    • By Gregory G.,

    Worst and most terrible supplement product I have ever used. It gave me terrible stomach aches when taking the recommended dosage, and I also had the worst tasting hiccups ever.

    This product, in my opinion, is just a rip-off.

    There is no accreditation at all that the ingredients used provides any help with increasing your Free Testosterone level. This is just a rip off to get you on an auto-ship program that charges your card $75.00 a month.

    Nugenix really must have paid huge amounts of money to have a famous ballplayer endorse such a worthless product.

    Bottom Line: No, I would not recommend this to a friend
