What is Nugenix Thermo

Nugenix Thermo is a thermogenic fat-burner distributed by Adaptive Health. The company is based in the USA and also distributes a number of other Nugenix supplements, including a multivitamin and several testosterone boosters. 

Nugenix Thermo is a thermogenic fat-burner

Adaptive Health describes Thermo as an “extreme metabolic accelerator.” It also states its formulation provides a unique blend of science-backed ingredients that have been shown to support a healthy metabolism, fat loss, and improvements in body composition.

That’s great to hear but good ingredients alone are not enough to deliver good results. They need to be delivered in sufficient quantities. Ideally in the same doses that have worked in clinical trials.

In this case, the formulation looks reasonably good, but it’s a little high in caffeine. This isn’t immediately obvious when you look at the supplement facts because it’s taken from several sources.

Collectively, they provide close to 200 mg of caffeine. That’s quite a lot to consume in a single dose. However, it’s no more caffeine than you would get if you drank a couple of cups of coffee back to back.

If you can do that without experiencing any jitters, heart palpitations, or other side effects, you should be okay with this supplement too but you may want to avoid coffee or other sources of caffeine for a few hours before and after doses. 

Nugenix Thermo Benefits

  • Boosts thermogenesis
  • Reduces body fat
  • Improves lean body mass

How to Use Nugenix Thermo

Unlike a lot of fat-burning supplements, Nugenix Thermo is a once-a-day gig. You take two capsules each morning and that’s it – job done for the day.

It’s permissible to take the capsules with or without food but if you’ve got a sensitive stomach, it’s probably best to have something to eat first.

How Does Nugenix Thermo Work?

Nugenix Thermo is a thermogenic fat burner. The main thing it aims to do is boost metabolism by increasing thermogenesis.

Metabolism and weight loss are closely related. Increasing metabolism means elevating the body’s energy expenditure higher than it is while you are resting.

During periods of inactivity, the body only uses energy to maintain normal biological activities such as breathing, thinking, digesting food, and blood circulation. This state is known as the basal metabolic rate (BMR).

Movement requires additional energy that raises the BMR. Running and other energetic physical activities produce significant increases in BMR, causing calorie expenditure to increase accordingly.

Within the confines of a low-energy diet, this increase in BMR can force the body to burn extra fat for energy.

Thermogenic compounds, such as the ones present in Nugenix Thermo, increase metabolism by causing the body to lose extra energy as heat. By doing this, they help you to lose more weight than you could with diet and exercise alone.

Most of the best weight management supplements are thermogenic fat burners. However, regardless of their indisputable value in weight management, thermogenic fat burners only work if you are making the correct efforts with your diet.

  • L-Carnitine L-Tartrate (30 mg)

Nugenix Thermo Ingredient Value

Vitamin C

Consuming extra Vitamin C is unlikely to support fat loss, but research suggests lack of this nutrient may contribute to weight gain. According to one study people who are Vitamin D deficient burn 30% less fat during exercise than people do who are getting an adequate amount.


Niacin is Vitamin B3. Like all B vitamins, it aids energy metabolism. It also relaxes the blood vessels. This improves circulation helping the muscles and major organs get a better supply of blood.


Chromium is a mineral that regulates blood sugar and insulin. Its ability to do this may prevent the post-meal blood sugar fluctuations that can trigger sugar cravings.

Sicilian Red Orange Extract

This extract comes from Italian blood oranges. Nugenix Thermo provides a branded version called Morosil. It’s not a popular diet pill ingredient but a limited amount of evidence suggests it may assist fat loss.

Caffeine Anhydrous

A highly refined caffeine powder that’s fast-acting and easy to absorb.

Caffeine is a stimulant that boosts energy. Research shows it also increases thermogenesis and metabolism.

Cayenne Extract

Cayenne provides capsaicin. It’s a plant chemical that supports weight loss in several ways including increasing metabolism, suppressing hunger, and converting white adipose tissue to brown adipose tissue.

Coleus Forskohlii Root Extract

Some studies suggest coleus forskohlii improves body composition by supporting increases in fat loss and improvements in muscle mass. Other studies suggest it does not.

Green Coffee Bean Extract

Green coffee beans provide chlorogenic acid. Like chromium, it’s good for regulating blood sugar and insulin.

Whole Coffee Fruit

This is a pointless inclusion. All it does is add extra caffeine. If Adaptive Health wanted extra caffeine, it would have been easier to add a little extra caffeine anhydrous.

The supplement facts state the coffee fruit in Nugenix Thermo is 70% caffeine. There is 50g of fruit per serving so if you do the math, that’s another 35 mg of caffeine added to each serving.

Ginger Extract

Ginger is a popular spice with many therapeutic virtues. It’s particularly good at easing stomach upsets. It also appears to assist fat loss but is far from being a power ingredient.

Guarana Extract

More caffeine! This time from a tropical berry. Nugenix Thermo provides 50 mg, at 20% caffeine. So that’s an extra 10 mg of caffeine dose.

Green Tea Extract

Green tea is one of the top diet pill ingredients. There’s a mountain of research showing it’s a metabolism booster that works.

The fat-burning ability of green tea is due to antioxidants, called catechins. In addition to being good for your waistline, green tea catechins are also good for your heart.

L-Carnitine L-Tartrate

This ingredient provides the amino acid L-carnitine. It’s an energy booster and muscle builder. L-carnitine also supports improvements in cognitive function.

What Customers are Saying About Nugenix Thermo

Customer reviews are mixed and, if you take the time to read them thoroughly, even the positive reviews fail to suggest this is a particularly effective product.

A lot of customers have reviews admitting they have only just received the product and haven’t had much time to try it.

Reports of weight loss are few and far between, while issues with side effects are quite common.

Known Side Effects of Nugenix Thermo

This formulation appears to be hard on the stomach. Lots of customer reviews mention cramps and/or diarrhea.

Other reported side effects include:

  • Rapid heartbeat
  • Headaches
  • Elevations in blood pressure
  • Insomnia

Many of the side effects customers report may be caffeine-related. 

However, like caffeine, coleus forskohlii may increase heartrate and cause headaches. It can present other side effects, including stinging eyes and skin flushing, as well.

Although some people appear to be able to use Nugenix Thermo without experiencing any negative issues, some of the reactions customers report are concerning. We suggest not using this product without getting clearance from a doctor first.

Nugenix Thermo Purchasing Options and Considerations

Nugenix restricts its marketing activities to North America, where its products are available in many of the larger chain stores such as Walgreens and GNC.

It also distributes its products via the official Nugenix website and Amazon. However, neither option offers shipping outside of the United States.

Nugenix Thermo Cost

At the time of this review, Nugenix Thermo cost $59.99 per bottle with a shipping charge of around $5 added on top.

According to the label snapshot that’s present on the official website and Amazon, each bottle provides 60 capsules. That’s 30 servings.

However, some reviewers are stating the capsule count has been reduced without warning. This certainly appears to be the case if you buy Nugenix Thermo from Walmart. The Nugenix Thermo sales page on the Walmart site makes it clear there are only 42 capsules in a bottle. That’s 21 servings.

The idea of paying around $60 plus shipping for a 3-week supply of pills does not sit well with us. There are plenty of alternatives that offer better value for money.


An emblem at the bottom of the Nugenix website promises a 30-day money-back guarantee. However, the site’s terms and conditions page says returns have to be unopened and unused.

Nugenix Thermo Review Conclusion

Nugenix Thermo provides several good thermogenic fat-burning ingredients. It can’t fail to be beneficial if you use it alongside a strict diet.

The formulation has quite a lot of caffeine in it so Nugenix Thermo should provide most people with extra energy too, along with improvements in mental focus.

However, the body adapts to caffeine over time. This causes it to be less effective. Depending on your caffeine tolerance, Nugenix Thermo could make you feel jittery and unwell, provide a nice energy buzz, or fail to influence your energy levels at all.

Customer reviews suggest feeling unwell is quite a common reaction and  the offer of a money-back guarantee has questionable merit. Bearing in mind the cost of the product and what the same money could buy instead (most of the top-performing weight loss pills), there are strong arguments for going with an alternative instead.
