Strongest fat burners: supplement reviews
As interest grows in the best fat burning supplements and their potential role in shedding pounds, our research has highlighted a set of fat burners that truly stand out. Join us as we unveil our findings.
1. PhenQ — best fat burner for night hours
Developed to help people lose weight during night hours and sleep, PM by PhenQ is one of the newer weight loss products on the market. It may be suitable for busy people who find time to take supplements only before bed.
In PhenQ PM, amino acids, vitamins, and minerals work together. Chromium in the mix is suggested to help with weight loss, while the inclusion of L-arginine may positively impact body composition, such as reducing weight circumference, BMI, and fat mass.
But then again, it's worth noting that while the provider’s website might make certain claims, actual results can differ from one person to another.
What’s also great about PhenQ is that it’s free from gluten, soy, and dairy and contains no preservatives. It also comes with a 60-day money-back guarantee, so if it doesn’t meet your expectations, you can return it within 60 days for a full refund.
To get the most out of PhenQ PM, the creators recommended taking 4 capsules 30 minutes to an hour before bedtime.
PhenQ PM comes in a bottle with 120 capsules, giving you a 30-day supply, and it’s available for $79.99.
2. Nucific — best fat burner supplement with probiotics
Nucific Bio-X4 is a dietary supplement advertised as a four-way defensive strategy — a strategy to help curb unhealthy cravings, promote weight management, improve metabolism, and support digestion.
The unique thing about this fat burner is that it comes packed with five Lactobacillus spp. and Bifidobacterium spp. probiotic strains and three digestive enzymes — amylase, lipase, and bromelain. And while the probiotics are intended to support digestive system, the enzymes work to help your body break down food more efficiently.
Along with probiotics, Nucific Bio-X4 also contains Caralluma fimbriata extract, believed to ease food cravings, and EGCG — a natural compound in green tea that numerous studies suggest may increase metabolic rate.
Bio-X4 is reportedly made with professionally sourced ingredients, and each formula is said to undergo testing at a third-party facility.
A 90-count bottle of Nucific Bio-X4 is available for purchase at $99.
3. Transparent Labs — best fat burning supplement to support body composition
Part of the PhysiqueSeries product line by Transparent Labs, Recomp Stim-free is, as the name suggests, a stimulant-free dietary supplement designed to help you maintain a leaner physique by improving your metabolic rate and curbing hunger and cravings throughout the day.
This supplement features ingredients like green tea leaf extract, Coleus forskohlii, grains of paradise, and red pepper extract. The last two are believed to help with energy balance by promoting energy expenditure.
Red pepper fruit extract, in particular, is known for its appetite-suppressing properties. It contains capsaicinoids from red chili peppers, which are thought to help curb appetite and increase feelings of fullness.
Recomp Stim-Free is available for $54.99, and that’ll cover you for two months.

How we compiled the best fat burning supplements in 2024
When putting together our list of the best fat burners, we took a careful look at a few key things to make sure we gave a well-rounded and accurate evaluation. Here's more detail on that:
Ingredients | Brand reputation | Safety aspect | Price |
Evidence-backed | Trustworthy | With a low level of risk involved | Options at different price points |
- Ingredients. Our top priority was to include products containing active ingredients backed by research and documented benefits in promoting fat loss.
- Brand reputation. Established and reputable companies with a history of producing high-quality supplements were given preference in our rankings.
- Safety aspect. Our primary concern was to ensure that the products posed minimal health risks. One key consideration was the presence of stimulants, such as caffeine, in the fat burners.
- Price. With consumers in mind, we made an effort to include options at different price points. Products that offered a good balance of quality and affordability ranked higher on our list.
How to choose the best fat burner in the market?
Before you decide on the best fat burner supplement that matches your preferences, it’s important that you take a moment to carefully evaluate your choice. Consider going through the tips we have laid out below:
- Check the ingredient list. Check the ingredient list for scientifically-backed fat-burning components. Common effective ingredients include caffeine, green tea extract, L-carnitine, and piperine. Avoid products with proprietary blends that obscure individual ingredient dosages.
- Examine labeling. Choose products with transparent labeling that clearly specifies the ingredients and their respective amounts used in the formulation. Also, if you happen to have any allergies, make it a priority to check for any potential allergens.
- Assess the safety profile. Be cautious of products with excessive amounts of stimulants or those making exaggerated claims. Consider consulting with a healthcare professional if unsure.
- Review real-world user experiences. Look for customer feedback on various platforms to understand the practical aspects of use and potential issues associated with the fat burner. Genuine user experiences can provide valuable insights into the product's performance and tolerability.
What ingredients effectively burn fat?
There are a number of ingredients that have been studied for their potential to promote fat burn and facilitate weight loss. Highlighted in the table below are those that have shown the most promise to date:
Ingredient | Benefit | Evidence |
Caffeine | Increases muscle performance and energy expenditure. May enhance fat oxidation and metabolic rate. | According to this meta-analysis, consuming caffeine could potentially lead to a decrease in weight, BMI, and body fat. |
Green tea extract | Promotes fat oxidation and has thermogenic properties — by means of these, it can support fat loss through multiple physiological pathways. | In 11 randomized trials, a meta-analysis showed a meaningful drop in body weight, BMI, and body fat for those with type 2 diabetes. |
L-carnitine | Plays a role in the oxidation of fatty acids, allowing the body to use fats as an energy source. | Meta-analysis of 37 randomized controlled trials involving 2292 participants revealed a notable reduction in body weight, BMI, and fat mass with L-carnitine supplementation. |
Piperine or black pepper fruit extract | Enhances nutrient absorption, supports metabolism. | In this animal study, it was observed that piperine increased lipolytic enzymes, resulting in a significant decrease in body and fat weight. |
It's important to point out that while these ingredients have shown promising effects, individual responses may vary. Instead of looking at these components as magic solutions, consider them as integral components of a comprehensive approach to a healthy lifestyle, which includes a balanced diet and regular exercise.
Do fat burning supplements actually work?
Even though there are many products out there on the market that claim the title of the best fat burner, the scientific evidence supporting their effectiveness is often mixed and inconclusive. While some studies suggest potential benefits, others have failed to demonstrate significant effects on weight loss or fat burning.
A short-term human study has revealed that the combination of green tea extract and caffeine led to a significant increase in 24-hour fat oxidation compared to the placebo group. These findings suggest a potential synergistic effect between green tea extract and caffeine in enhancing fat oxidation in the short term.
On the flip side, after comparing fat burners and thermogenic supplements to diet and exercise for weight loss, this meta-analysis suggests that including thermogenic dietary supplements may provide limited benefits in reducing body mass for those with excessive fat mass.
All things considered, while the best fat burner supplements are linked with some benefits in fat loss, their efficacy is not universally guaranteed and is often very individual. This makes approaching even those marketed as the best fat burning supplements with realistic expectations essential.

FAQ
Do fat burners work for everyone?
No, they don’t. Fat burners may not work the same way for everyone, as their effectiveness not only heavily depends on factors such as genetic makeup and individual metabolism but is also intertwined with lifestyle choices. A sedentary lifestyle, poor dietary habits, and lack of exercise can undermine the potential benefits of these supplements. Fat burners are most effective when paired with a balanced diet and regular physical activity.
Do fat burners have any side effects?
They do. While common side effects associated with fat burners include increased heart rate, sleep disturbances, digestive issues, and headaches, the nature and severity of these potential side effects may vary depending on the specific ingredients and their amounts in the supplement. To minimize these potential risks, it is imperative to closely follow the recommended dosages.
Can I combine fat burners with other supplements?
Be cautious. Combining fat burners with other supplements should be approached with a discerning eye. Although some combinations may be safe and even synergistic, others can lead to adverse reactions or interactions. It's essential to consider the ingredients and potential effects of each supplement. For added reassurance, don’t hesitate to reach out to a healthcare professional.
How long does it take to see results with fat burners?
It depends. The timeframe to see results with fat burners is highly individual. While some users may notice changes relatively quickly, for others, it may take longer. Significant weight loss or body composition changes typically require consistent use over several weeks to months. It's important to manage expectations and prioritize a well-rounded approach to weight management, including balanced nutrition and regular physical activity.
