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 - 1 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.

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.
