Nugenix Reviews: Best Seller Products In 2024

Nugenix Total-T

Nugenix Total-T

If you are on the lookout for the best scientifically proven ingredients that are natural testosterone boosters, then the Nugenix Total-T is one of the best. It is stimulant-free and contains no fillers.

  • Maximizes male performance
  • Contains no fillers
  • Stimulant-free
  • Expensive
  • Contains gelatin

Manufacturers believe their testosterone booster solution helps men reach their full potential. They claim their blend improves free and total testosterone to maximize gym gains. Testosterone boosts strength, muscle, vitality, and endurance.

One bottle with 30 servings of three capsules daily costs $69.99 / bottle. Here is the entire ingredients list:

  • Vitamin B6 (as pyridoxine hydrochloride): This ingredient helps increase testosterone production since it is a known sex hormone regulator.
  • Vitamin B12 (methylcobalamin): The quantity, quality, and viability of sperm[1] are all influenced by vitamin B12. High B12 levels can increase energy[2], endurance, digestion, and cognition independent of testosterone boosting.
  • Zinc (zinc chelate): This helps to increase free testosterone[3] and improves sperm count.
  • L-Citrulline Malate: L-citrulline enhances blood flow and nitric oxide concentrations, both of which will aid rectile dysfunction[4] while increasing testosterone levels.
  • Fenugreek Extract: The serum total testosterone levels[5] in men are impacted by this component.
  • elevATP® Blend [Apple Fruit Extract and Ancient Peat Extract (trace minerals)] This blend is proposed to increase our levels of adenosine triphosphate[6], also known as ATP, our energy molecule. Physical performance is enhanced with increased levels of ATP; thus, this blend may increase physical strength and stamina.
  • Boron (as boron glycinate): This may help increase testosterone levels[7] in men.
  • Eurycoma longifolia Extract (root): This herbal extract contains several compounds that appear to impact how the body makes the hormone testosterone and may even raise the body’s testosterone levels[8]. There is also evidence it supports muscle strength[9] in human beings.

Nugenix Thermo

Nugenix Thermo

The Nugenix Thermo is the most effective treatment for someone who wishes to improve their body composition while simultaneously losing a few pounds of fat and doing so by burning fat.

  • Thermogenic
  • Remedy for weight loss
  • The ingredients have been clinically verified
  • Contains gelatin

The natural components’ thermogenic properties in Nugenix Thermo make them stand out the most. Thermogenic substances have a heating impact on the human body, speeding up the body’s metabolism and increasing the pace at which it burns calories and fat even while it is resting.

The entire ingredient list is as follows:

It costs $59.99 for a bottle of 30 servings of two capsules each serving.

Nugenix Free Testosterone Booster

Nugenix Free Testosterone Booster

Unlike other testosterone boosters with pages-long of artificial ingredients and fillers, this one only has six key ingredients. This combo has testosterone-boosting effects, improves sexual health, and helps the male body enhance athletic performance.

  • Boosts low testosterone levels
  • Contains natural ingredients
  • Contains gelatin
  • Has proprietary blends
  • Serving size is three capsules

This simple formula may help men improve libido, mood, and physical performance by naturally boosting testosterone levels. A month’s supply of one bottle costs $69.99. Taking Nugenix Testosterone Booster will offer your body the following key ingredients:

  • Vitamin B6
  • Vitamin B12
  • Zinc Chelate
  • Nugenix® Free Testosterone Complex with
    • L-Citrulline Malate facilitates better blood flow[21] and muscle health and helps improve physical performance during strenuous exercises such as strength training.
    • Fenugreek Extract helps the male body with sexual stamina, drive, energy, and optimal physical fitness.
    • Tribulus Extract enhances male libido[22].

Nugenix Ultimate

Nugenix Ultimate

The most compelling marketing claims the brand uses for the Nugenix Ultimate are that it promotes androgenic activity, is a free testosterone booster and improves your sex drive.

  • Maximizes muscle growth and strength
  • Boosts free testosterone levels
  • Modulates androgenic activity
  • It is more expensive than most testosterone-boosting supplements
  • Contains maltodextrin

This formula claims that it stimulates and encourages androgen activity in the human body. Androgens[23] are vital to sexual health in the male body, also impacting metabolism, bone, and muscular development. 

For male sexual and reproduction functions, androgens are essential. They are also in charge of the vocal transformation and growth of secondary sexual traits in men, such as face and body hair growth., It uses the following formula to do that in addition to testosterone boosting.

  • D-Aspartic Acid[24] may help raise t-levels in the male body.
  • Epimedium extract, also Horny Goat Weed, is a potent natural testosterone booster. It has been used in traditional medicine with no human studies yet. The only ones available are animal studies[25].
  • Fenugreek extract boosts total testosterone levels.
  • Stinging Nettle extract increases free testosterone levels[26].
  • Eurycoma longifolia extract boosts athletic performance and sexual health and prevents erectile dysfunction[27].
  • Maca extract may increase libido, improve mood, sperm motility[28], and concentration, and improve symptoms caused by erectile dysfunction.
  • Mucuna pruriens extract may help with male fertility[29] and is an aphrodisiac.
  • Boron helps regulate sex hormones[30] and helps increase testosterone levels.
  • Maltodextrin may adversely affect the gut microbiome[31] and is ultra-processed, having a glycemic index higher than sugar.

The cost is $89.99 for 30 servings of four pills each serving.

Nugenix Total-T Maxx

Nugenix Total-T Maxx

The Nugenix Total-T Maxx is supposedly the brand’s most treasured product, promising men a boost in low testosterone levels. The effects are increased sex health, better athletic performance, higher energy levels, and lean muscle gains.

  • Enhances male performance
  • Helps users gain lean muscle mass
  • May help increase libido
  • It is a costly formula
  • Contains maltodextrin and artificial food coloring

One of the most dreaded effects of declining testosterone levels is a low sexual drive, low energy, mood changes, and a loss of motivation. But these are all things that the Nugenix Total-T Maxx promises to reverse and help with using the following ingredients. It costs $169.99.

  • Vitamin D is a testosterone-boosting ingredient.
  • Zinc helps boost testosterone levels.
  • Fenugreek extract naturally boosts testosterone levels.
  • Ashwagandha extract enhances sexual desire, improves sperm motility[32] and sperm concentration, boosts t-levels, and improves erectile dysfunction.
  • Shilajit purified extract increases total and free testosterone levels[33].
  • Eurycoma longifolia extract boosts physical performance.
  • Rhodiola extract enhances exercise performance, cognition health[34], and mental health.
  • Maca extract boosts sexual desire.
  • Asian Ginseng (Panax ginseng) extract may help with erectile dysfunction[35], brain health, and energy levels.
  • Black Ginger extract[36] increases physical performance and muscular stamina.
  • White Button Mushroom extract is prostate cancer protective[37].
  • Black Pepper extract also has anti-cancer properties[38].
  • Contains maltodextrin and artificial food colors, which are noted to be controversial ingredients approved by the FDA but, regardless, showing evidence for adverse health effects in some individuals.

Is Nugenix Safe?

Please be aware that any testosterone booster you purchase without a prescription has not been evaluated by the Food and Drug Administration (FDA). They are only to be used as supplements. They are intended to supplement the body with much-needed nutrition (adding a balanced diet) but not to be medication replacements.

Nugenix reviews online from past clients that have evaluated the featured ingredients may give us a glimpse at effectiveness and potential problems with the product line.

In most online reviews posted on the official website, it is stated that Nugenix works. And the voice is almost the same on Amazon, with clients praising its positive energy and vitality-boosting properties.

Regardless, some Nugenix reviewers have highlighted side effects that may cause skin flushing, nausea, and vomiting. Before using this and other supplements, get your doctor’s medical advice, assessment, and clearance. When it comes to answering is Nugenix legit, we believe it is after reading Nugenix reviews, and there is no history of recall.

What Do We Like About Nugenix?

Here are some of the things that we like about Nugenix as a brand:

Medical Board Team

The brand’s co-founder is part of a well-educated team of experts in the formula creation process. This indicates that the creation of the Nugenix product line has scientific backing on each ingredient, down to the recommended dosage of each.

A Wide Variety Of Testosterone Boosting Supplements

Another aspect we like about Nugenix is its wide variety of supplements designed for prostate health and boosting testosterone. They have Nugenix Ultimate, Nugenix Maxx, and Nugenix Total T as testosterone boosters. They also have weight loss supplements like the Nugenix Thermo and, for sound sleep Nugenix PM ZMA. This variety offers clients more options if they find an ingredient they are allergic to or reactive to.

From a business standpoint, this is a brilliant sales strategy since they are selling numerous products for a similar end goal and adding benefits to make them unique.

The Free Sample Incentive

Once you get to the official Nugenix website, at the very bottom, you have a Call to Action (CTA) to get free samples. This is yet another smart thing we like about this brand. With such a gesture, they are showing clients that they are open to offering an incentive so that you give their product a try.

Doing this garners an unlimited pool of client feedback and potential life-long buyers. They also get willing consumers to leave constructive Nugenix Ultimate reviews, Nugenix Thermo reviews, or reviews for any other product in their portfolio.

Final Thought

Testosterone boosters claim that they’ll boost energy levels, naturally, raise t-levels, and improve sexual health, mental sharpness, muscular growth, prostate health, and athletic performance.

They attribute all these benefits to the ingredient list they have. Nugenix’s scientific support for each ingredient’s efficacy is the supplement’s success story. They provide a product that men require because the ingredients in their blends are proven through research. The only drawback is that it can take more than a few weeks to start seeing effects.

Lastly, customers have given mixed feedback on Amazon and other websites, although the positives seem to be winning. There is proof that the company sells top-notch goods. But before using it, consult your physician and registered dietitian nutritionist (RDN).
