Thermogenic fat burners comprise a sizeable share of the fat-burning supplements market. The body produces heat naturally as a result of the process of thermogenesis. This significantly influences how metabolism and energy expenditure are regulated. Increasing thermogenesis can result in burning calories and fat reserves, which can help with body fat loss.
A heavily marketed entry into the thermogenic fat burner market is Nugenix from Adaptive Health. Some pretty big claims are made for this product; in this review article, we'll find out whether they hold up. So is Nugenix the real deal, or is it nothing but overpriced marketing hype? Read on to get the unbiased facts on this fat burner.

What is Nugenix Thermo?
Nugenix Thermo is a thermogenic fat burner designed to promote the thermogenic process to speed up metabolism and calorie burn. It is produced and marketed by Adaptive Health, headquartered in Charlotte, North Carolina. This is one of 15 supplements produced by the company.
Nugenix Thermo Review: Pass or Fail?
Nuegnix Thermo relies on a single mechanism for burning fat; thermogenesis. As a result, it does not include proven weight loss ingredients such as glucomannan for appetite suppression. Furthermore, those ingredients that it does contain are generally underdosed.
For example, you get 154 mg of the critical thermogenic ingredient, caffeine. However, you need to take 200-400 mg daily for a noticeable thermogenic effect.
In the final analysis, there are far better options for Nugenix Thermo for fat and weight loss supplements. Check the alternatives section further down for three fat burner recommendations.
Overall Verdict: FAIL
Pros
- Decently priced
- Good variety of ingredients
- Manufactured in a GMP-compliant facility
Cons
- Ingredients are underdosed

13 Nugenix Thermo Ingredients
Here's a brief overview of the 13 ingredients in Nugenix Thermo, focusing on why they have been included in this fat-burning supplement.
1. Vitamin C - 17 mg
Vitamin C is necessary for many body processes. Thermogenic fat burners may contain vitamin C due to their potential advantages in promoting general health and weight control. Vitamin C is a potent antioxidant that works to shield cells from damage brought on by free radicals. It can help reduce the oxidative damage brought on by a thermogenic fat burner's increased metabolism.¹
2. Niacin - 16 mg
Niacin, or Vitamin B3, plays a crucial role in cellular metabolism, helping turn carbs, lipids, and proteins into energy. It may indirectly help the body's capacity to burn calories and fat during thermogenesis by encouraging effective energy generation.²
Niacin can temporarily enlarge blood arteries, which is known as vasodilation. This effect is frequently referred to as the "niacin flush." The supply of nutrients and oxygen to tissues during exercise or physical activity may be aided by dilating blood vessels and improving blood flow and circulation. However, the form of niacin (vitamin B3) in Nugenix Thermo is niacinamide, which does not dilate blood vessels like the niacin form does.
3. Chromium - 200 mcg
Chromium is a trace mineral that has the potential to influence metabolism and blood sugar management. It contributes to insulin sensitivity and is involved in the metabolism of carbohydrates. It might also enhance the body's response to insulin, which could help control blood sugar levels. Chromium may indirectly help with weight management and thermogenesis by fostering stable blood sugar levels.³
4. Sicilian Red Orange Extract (fruit) - 400 mg
Sicilian Red Orange Extract, which is made from blood oranges cultivated in Sicily, Italy, is an ingredient that occasionally appears in thermogenic fat burners due to its possible effects on metabolism and weight management. Anthocyanins and flavonoids, recognized for their antioxidant qualities, are notably abundant in this extract.⁴
5. Caffeine anhydrous - 154 mg
Caffeine anhydrous may boost energy by activating the central nervous system, making you feel more energized and concentrated during workouts or physical activities.
Studies have shown that caffeine intake increases metabolic rate and improves fat oxidation, which may aid in weight loss and thermogenesis. In addition, it can support calorie burning by stimulating the breakdown of fat cells.⁵
For a higher amount of caffeine, check out a list of the Best Caffeine Pills.
6. Cayenne Extract - 100 mg
Cayenne extract has thermogenic qualities, which can help raise body temperature and metabolic rate. This rise in metabolic activity may increase fat oxidation and calorie burning, helping you lose weight.
Capsaicin, the active ingredient in cayenne extract, is thought to have appetite-suppressing properties. It might support feelings of fullness and curb cravings, potentially assisting with calorie restriction and weight management.⁶
7. Coleus forskohlii Extract - 100 mg
It has been demonstrated that forskolin, the main ingredient in Coleus forskohlii extract, raises cellular levels of cyclic AMP (cAMP). Several metabolic activities, including fat metabolism, are regulated by cAMP. Therefore, Coleus forskohlii extract may improve the breakdown of stored fat and help weight loss by raising cAMP levels.⁷
8. Green Coffee Extract - 75 mg
Chlorogenic acid, the active ingredient in green coffee extract, may help promote thermogenesis and healthy metabolism, increasing the body's calorie expenditure and thus assisting with weight loss attempts.
Chlorogenic acid, present in green coffee extract, may aid in controlling blood sugar levels. It may decrease blood sugar rises after meals by preventing the release of glucose into the bloodstream, which may help with appetite suppression and weight management.⁸
9. Whole Coffee Fruit - 50 mg
Whole coffee fruit extract contains natural caffeine, recognized for its stimulating qualities. It also includes chlorogenic acid, like the green coffee bean extract. This substance may support fat metabolism, control blood sugar levels, and aid in weight loss attempts.⁹
10. Ginger Extract - 50 mg
Ginger has a thermogenic impact on the body, helping to raise body temperature and metabolic rate. Ginger is also well-known for its advantages for digestion. It may lessen bloating, support good digestion, and ease stomach discomfort.¹⁰
11. Guarana Extract - 50 mg
Guarana extract has a high caffeine content. Caffeine can improve athletic performance by boosting alertness and energy levels. In addition, because it stimulates the central nervous system and encourages thermogenesis, it may also help improve metabolism and fat burning.¹¹
12. Green Tea Extract - 50 mg
The most prevalent and biologically active catechin in green tea extract is epigallocatechin gallate (EGCG). Caffeine and EGCG may combine to stimulate thermogenesis, raise metabolic rate, and improve fat oxidation.¹²
13. L-Carnitine L-Tartrate - 30 mg
L-Carnitine L-Tartrate (LCLT) is an amino acid-like compound in fat metabolism and energy production. It boosts fatty acid transportation, supports the breakdown of stored fats, and increases cellular energy production.¹³

2. Instant Knockout
Instant Knockout is a fat loss supplement from the UK company Roar Ambition. It was initially designed to help martial artists lose fat to achieve their competition weight class. It uses three methods to achieve weight loss:
-
Metabolism boost
-
Ability to suppress appetite
-
Increased energy
The nine active ingredients in Instant Knockout provide a combination of thermogenic and non-thermogenic effects. Caffeine, green tea extract, and cayenne pepper seeds are the primary thermogenic ingredients. Glucomannan, a well-established appetite suppressant, serves as the principal non-thermogenic ingredient in this product. Finally, vitamins, B6 and B12, are responsible for tying everything together and giving you that extra boost of energy.
Roar Ambition has done an excellent job when it comes to dosing Instant Knockout's ingredients to produce results; There are 300 mg of caffeine anhydrous, 500 mg of green tea extract, and 1800 mg of glucomannan per serving, all of which are within the effective range. All in all, it adds up to a quality fat burner.

Can women use Nugenix Thermo?

Summary
Nugenix Thermo results rely on thermogenesis to promote fat loss. However, it doesn't dose its thermogenic ingredients high enough to produce a significant effect. It's also missing appetite-suppressant ingredients such as glucomannan. As a result, the weight loss results you'll achieve will be modest at best. We recommend giving Nugenix Thermo a pass and investing in a product like PhenQ, which works through several complementary mechanisms to achieve weight loss.
