It Works! TFXX — Next Gen Fat Burn & Metabolic Support
It Works! TFXX Review
Weight-loss thermogenic supplements come in many forms — from gummies to teas to capsules — and one of the products that stands out in the It Works! lineup is It Works! TFXX (Thermofight XX). Marketed as a next-generation fat-burning thermogenic formula, It Works! TFXX aims to help people boost their metabolism, increase energy, and support weight loss when combined with a healthy diet and lifestyle. But what exactly is it? How does it work? And does it really deliver?
In this in-depth review, we’ll break down what It Works! TFXX is designed to do, the science behind its key ingredients, how they may affect metabolism and fat burning, and what to realistically expect from using this supplement.
What Is TFXX and What Does It Do?
It Works! TFXX is a dietary supplement in capsule form that falls into the category of thermogenic fat-burning products. Thermogenesis refers to the body’s process of producing heat — and in supplement marketing terms, it’s often used to suggest increased calorie expenditure and fat oxidation by heating up the body’s metabolism.
According to its official product description:
- TFXX is designed to enhance fat-burning thermogenesis.
- It contains caffeine and other stimulants to boost energy and alertness.
- The formula includes clinically studied compounds intended to support weight-loss goals when paired with a reduced-calorie diet and exercise.
- It reports to help users move into a fat-burning metabolic state more easily.
Users are typically advised to take one capsule twice daily with meals and drink plenty of water. It Works! TFXX contains caffeine (~125 mg per two servings), so it should not be taken on an empty stomach and isn’t recommended for people sensitive to stimulants.
Active Ingredients: The Heart of TFXX
The It Works! TFXX formula combines several ingredient classes associated with metabolic and thermogenic effects. Let’s take a closer look at each one and what evidence, if any, exists to support its role in weight-management.
1. Greenselect® Phytosome (Green Tea Extract Complex)
The star ingredient in TFXX is Greenselect® Phytosome — a proprietary green tea extract complex bound to phospholipids to enhance absorption. This ingredient is commonly used in weight-loss supplements due to its high content of EGCG (epigallocatechin-3-gallate), a powerful antioxidant shown in some trials to support fat oxidation and modest weight loss.
Green tea antioxidants can slightly increase metabolic rate and fat oxidation in some individuals, particularly when combined with caffeine, but the effects are small and variable between people.
The product description states that Greenselect® Phytosome has been used in research associated with an average weight loss of about 31 pounds over 90 days when combined with a reduced-calorie diet — compared to around 11 pounds with diet alone — but this result comes from a specific study context (diet + exercise) rather than the supplement alone.
What the study showed:
“Greenselect Phytosome® as an adjunct to a low-calorie diet for treatment of obesity: a clinical trial” — a randomized, controlled study involving 100 overweight adults.
- Participants were split into two groups — both followed a hypocaloric diet, but one group also received Greenselect® Phytosome® (a highly bioavailable green tea extract) while the other group received the diet alone.
- Over 90 days (approximately 3 months), both groups lost weight, but the group taking the green tea extract saw significantly greater reductions in body weight and BMI than the diet-only group.
Results of the Trial
In this study:
- The group taking Greenselect® Phytosome plus a reduced-calorie diet lost about 14 kg (~30 lbs) on average.
- The diet-only group lost about 5 kg (~11 lbs) over the same period.
This difference is where marketing claims of “~30 lbs vs. ~11 lbs” originate, although it’s important to underscore that the extract wasn’t tested on its own — it was used in combination with a controlled, calorie-restricted diet (1).
Why This Matters
- The study does show an enhanced weight-loss effect when Greenselect® Phytosome is added to a low-calorie diet versus diet alone.
- But the results do not mean the extract will cause that level of weight loss by itself without calorie restriction, exercise, and other lifestyle factors.
- As with all clinical research, individual results may vary based on diet, activity, genetics, and adherence to study protocols.
Summary
So the study supporting this claim is the 90-day trial of Greenselect® Phytosome with a hypocaloric diet — which found that the group taking the green tea extract in addition to calorie reduction lost significantly more weight than those on diet alone (1).
Takeaway: Green tea extract with EGCG may modestly support metabolism and fat oxidation, especially with caffeine and a calorie deficit, but it’s not a standalone weight-loss miracle.
2. Caffeine
Caffeine is a central nervous system stimulant found naturally in coffee, tea, and many weight-loss supplements. In TFXX, the combination of green tea extract and added caffeine is geared toward supporting:
- Increased alertness and energy,
- Enhanced fatty acid release from fat stores,
- Short-term boosts in metabolic rate.
Studies show that caffeine can temporarily increase calorie expenditure and fat oxidation, particularly in people who are not habitual caffeine consumers. However, the size of the effect tends to be modest — for example, a slight increase in energy expenditure for a few hours after intake.
Takeaway: Caffeine can help with energy and short-term metabolic boost but is not sufficient to guarantee significant weight loss on its own.
3. Green Coffee Bean Extract
Green coffee bean extract is another plant-derived ingredient often included for its chlorogenic acids, which some studies associate with modest reductions in body weight and fat accumulation, especially when combined with lifestyle changes.
Clinical evidence suggests that chlorogenic acids may have modest metabolic effects, but results vary and the evidence is not as robust as for traditional weight-loss strategies like diet and exercise.
Takeaway: Green coffee bean extract may support weight-loss metabolism in some contexts, but benefits alone are small.
4. Thermogenic Blend (Jalapeño, Cayenne, Ginger, Cinnamon, Black Pepper)
It Works! TFXX includes a blend of thermogenic spices such as jalapeño pepper, cayenne pepper, ginger, cinnamon, and black pepper. These are included for their potential to:
- Increase metabolic rate through mild thermogenic effects (especially capsaicin in peppers).
- Support circulation and digestion.
Capsaicin has been studied for its ability to slightly boost energy expenditure and reduce appetite, but again, the effect sizes are modest. Black pepper is typically used to enhance bioavailability of other compounds, while cinnamon and ginger add metabolic and digestive support in small ways.
Takeaway: The thermogenic spice blend may offer minor metabolic perks, but it’s supplemental to overall diet and exercise changes.
5. Chromium (Chromium Dinicotinate Glycinate)
Chromium is a trace mineral that is often marketed for blood sugar regulation and appetite control. Some research suggests chromium may play a small role in carbohydrate metabolism, but clinical results on weight loss are mixed and modest.
Takeaway: Chromium may help with macronutrient metabolism and cravings in some people, but it’s not a powerful weight-loss agent on its own.
Effectiveness: What the Science Really Says
- Thermogenesis can be supported — ingredients like caffeine, green tea extract (EGCG), and capsaicin have some evidence for increasing metabolic rate, but effects are modest.
- Weight-loss studies involving green tea extract plus calorie restriction show modest benefits for weight and fat reduction — but these are not dramatic on their own without a diet and exercise plan.
- There’s no independent clinical trial proving that TFXX by itself causes large amounts of weight loss in consumers.
So, while the branded ingredients in It Works! TFXX have been studied for metabolic effects, it’s important to understand that supplements are not magic solutions. Sustainable weight loss still relies heavily on dietary changes and physical activity.
Real-World Use & User Feedback
Online reviews for It Works! products — including It Works! TFXX — tend to be mixed. Some consumers report increased energy and mild weight loss when TFXX is paired with calorie control and exercise, while others see minimal changes or none at all.
It’s also worth noting that experiences with any supplement can vary widely due to individual biology, diet adherence, activity level, and expectations.

Conclusion: A Tool, Not a Cure
It Works! TFXX Thermofight XX 60 Caplets is a thermogenic, weight-management supplement that combines green tea extract, caffeine, spices, chromium, and other compounds to support metabolism and energy levels. While many of these ingredients show some scientific potential for modestly increasing metabolic rate and supporting fat oxidation, they are not stand-alone solutions for weight loss.
For best results, It Works! TFXX should be used as part of a holistic approach: balanced nutrition, regular exercise, adequate sleep, and hydration. With realistic expectations and consistent habits, TFXX may provide an energy and metabolic boost — but it won’t replace foundational lifestyle strategies such as diet and exercise.
