Brand trustworthiness

Let’s be honest here; if you can’t trust a brand, then it’s difficult to be confident about their products. Some brands are associated with ineffectiveness, strong side effects, poor customer service, and other negative traits that act as a warning sign telling people to stay away. For some people, it can be difficult to recognize these warning signs immediately.

Did they find them beneficial? Did they regret spending money on them? These reviews helped rule out products that aren’t good enough but also shaped our list with supplements that users found truly effective.

Overall quality

Brand trust should go hand in hand with the quality of the product. We made sure the list features only those fat burners with superb quality to provide the results you need and expect.

The whole process of making a fat burner supplement matters a lot to us.

1. PhenQ

1 PhenQ

The brand

If you’ve searched for fat burners online the chances are high you came across PhenQ, one of the most popular products of this kind on the market. PhenQ, sold exclusively on the official website, is supplied and manufactured by Wolfson Berg Limited, a brand that has been in the supplement industry for decades.

Over the years, the brand has earned respect and admiration of the ever-growing customer base that uses its supplements to burn body fat quickly and increase muscle mass. Wolfson Berg Limited believes in upholding the highest quality standards in everything they do, and the close inspection into this product shows their mission is accomplished successfully. You can read the full PhenQ review too which is posted on this site.


PhenQ is marketed as a natural weight loss and fat burning dietary supplement that provides multiple weight loss supplements in just one pill. In other words, the product is formulated in such a way to work through several mechanisms to help people slim down and burn body fat easily.

The key to the fat-burning potential of PhenQ comes down to a unique formula a-Lacys Reset, which is a result of combining science with cutting-edge technology. The trademarked formula is specifically developed to accelerate the metabolism and help burn fat through the process called thermogenesis.

PhenQ also contains ingredients such as:

  • Capsimax powder – a blend of capsaicin (active compound from chili peppers), piperine (the active compound in black pepper), niacin (vitamin B3), and caffeine. Both capsaicin and piperine exhibit strong thermogenic effects which allow people to slim down i.e., burn fat by increasing body heat
  • Chromium picolinate – a supplemental form of chromium, an essential trace mineral with important roles in the body ranging from insulin sensitivity to enhanced metabolism of lipid (fats), carbohydrates, and protein. The addition of this ingredient to the formula helps women curb cravings for sugar and carbs. That way, you manage to control blood sugar more effectively and lose weight faster. After all, one of the biggest reasons behind slow weight loss results is the excessive intake of sugar-laden foods and carbohydrates.
  • Caffeine – acts as a stimulant that enhances alertness, focus, and decreases fatigue while curbing your hunger and promoting thermogenesis to help burn fat. Caffeine can also help you get the maximum out of your workout routine as it improves your performance.
  • Nopal – a common name in Spanish for Opuntia cacti i.e., prickly pear. Nopal is abundant in fiber that promotes a sense of fullness. In turn, nopal can suppress appetite and prevent overeating, a common problem today. Besides fiber, nopal is rich in amino acids that have the potential to increase energy levels and support weight loss. What makes nopal a great addition to PhenQ is the fact it can flush fluids from tissues and tackle “water weight” problem
  • L-carnitine fumarate – increases muscle strength and energy while helping people lose weight and burn fat. L-carnitine is a naturally occurring amino acid that aids the transportation of fatty acids into the mitochondria of cells where excess fat is broken down and converted for energy.

Does it work?

Over 190,000 people use PhenQ, which turned out to be the best fat burner for women and men alike. The manufacturer also provides links to studies that confirmed the efficacy of the ingredients in the formula. This is important because most brands don’t do such a thing.

PhenQ works to burn stored fat, suppress appetite, block the production of fat, and boost energy levels, which improve a person’s mood and athletic performance. The multichannel mechanism of action makes PhenQ stand out in the sea of fat burner supplements.

It’s worth mentioning that the clinical trials which focused on a-Lacys Resent found that this trademarked formula can help decrease body weight and body fat but also increases muscle mass. This way, PhenQ solves the common problem that people face – along with lost weight, they also lose muscles. On average, people who consumed a-Lacys Reset lost 7.24% body fat, 3.44% body weight, and increased muscle mass by 3.80%.

One-month supply bottle contains 60 tablets taken twice a day (one with breakfast and the other with lunch)

What are people saying about it?

The brand

If you’re looking for the best fat burner for women that even pro athletes and fighters would use, then Instant Knockout is a reasonable choice. Made by the Instant Knockout brand, this product is all about fighting whether it’s gaining your muscle mass or burning fat with an energy boost and other effects that help you get into the best shape.

The brand is well-known among fighters, athletes, and other active women who use Instant Knockout regularly to achieve their body goal or sustain it. Even the shape of the bottle, which contains 120 capsules, symbolizes fight and energy. It’s not a standard-looking supplement bottle, which is definitely a nice touch. You can check the full instant knockout review here.


The formula through which Instant Knockout works is based on the years of tracking scientific research that identified reasons behind fat storing and mechanisms that fight it. This fat burner has a truly rich formula that focuses mainly on green tea extract, cayenne pepper seeds, and glucomannan.

Green tea is one of the healthiest beverages on the planet thanks to its powerful active compounds. Weight loss products often contain green tea extract because it can speed up metabolism and elevate total energy expenditure. In other words, green tea allows users to burn more calories during the day.

Cayenne pepper seeds are abundant in vitamin A, C, and B6, as well as the active compound capsaicin. The addition of this ingredient to the formula improves insulin sensitivity, accelerates metabolic rate, and promotes fat burning.

On the other hand, glucomannan is a type of fiber that suppresses appetite and prevents overeating and cravings. And we all know that most cravings are for unhealthy foods.

Besides the above-mentioned ingredients, Instant Knockout also contains:

  • Caffeine anhydrous – stimulant, boosts energy, improves athletic performance, reduces fatigue.
  • Vitamin B6 – improves the way the body uses energy, supports general health, improves metabolism and fat oxidation, helps build muscle.
  • Vitamin B12 – elevates metabolism and athletic performance, strengthens the immune system and improves mood, improves digestion of carbohydrates, and maximizes protein synthesis for leaner and more athletic shape.
  • GTF chromium – promotes insulin control and metabolism of sugar and fat, boosts energy and athletic performance, reduces appetite and cravings
  • Zinc – essential mineral that which helps the body process carbs, fat, and proteins to boost energy
  • Piperine – supports digestion, accelerates metabolism, elevates thermogenesis, activates TRPA1, and TRPAV1 receptors to suppress fat accumulation.
  • Green coffee bean – i.e., unroasted coffee beans, but don’t contain caffeine. They contain a cholinergic acid compound that slows down fat absorption from food, reduces sugar cravings, lowers cholesterol.

Does it work?

The Instant Knockout, available on the official website, is considered a highly effective fat burner that works for both genders alike. Originally developed for MMA fighters and boxers, Instant Knockout aims to address the stubborn nature of stored fat, which is a common struggle for many women.

This fat burner uses a triple approach to exhibit its effects. First, it boosts the metabolic rate to burn more calories and fat. Then it works to reduce hunger cravings to decrease the number of calories, especially fat, you eat and store. And finally, Instant Knockout elevates energy levels to allow users to achieve optimal athletic performance.

The 75mg capsules are taken four times a day i.e., one first thing in the morning, one before lunchtime, one in the afternoon, and the fourth one before the evening meal.

What are people saying about it?

Instant Knockout users are, in fact, impressed with the results they experienced. Users reported the supplement worked to “unlock” their metabolism and ensure they keep losing weight when other products of this kind didn’t. One customer reported losing 2-2.5kg (4.5-5.5lbs) a month without any adverse reactions. Others described the appetite suppression is felt quickly and were even surprised when it kicked in. Instant Knockout even helped kickstart the journey toward bikini competition for some female users.

phen24 53

The brand

You probably find Phen24 name similar to the above-mentioned PhenQ, and you’re right – they’re similar, but it’s not a coincidence. Both products are made by the same brand Wolfson Berg Limited which is well-known in this industry and among people who want to slim down and sculpt their bodies.

Phen24, available on the official website, is dubbed as the industry’s first metabolism fueling system that heightens thermogenesis even when you sleep. Unlike other products on the market, this one comes in a set of two bottles where daytime Phen24 consists of 30 capsules and nighttime Phen24 has 60. One is a day and the other night pill.


Low-functioning metabolism is a prevalent problem, and Phen24 was specifically created to help users solve this problem. The potential efficacy of Phen24 comes as a result of a powerful formula for both day and night versions.

Daytime ingredients include minerals such as zinc, manganese, copper, and iodine. Zinc boosts metabolism function while manganese nourishes nerves and brain to improve the relationship between the brain, nerves, and muscles. On the other hand, copper boosts energy levels and improves athletic performance while iodine supports thyroid function and provides positive body effects.

Other ingredients in daytime Phen24 include caffeine and cayenne powder, which promotes thermogenesis, alertness, and boost energy levels. Guarana extract reduces fatigue and improves performance. And finally, l-phenylalanine suppresses appetite.

On the flip side, nighttime Phen24 includes ascorbic acid (vitamin C) to improve the growth and repair muscle fibers, calcium do enhance memory and increase stamina, pyridoxine Hcl to help convert food into fuel that makes it easier for the body to metabolize proteins and fats. Additionally, chromium aids blood sugar management and reduces cravings while the addition of thiamine Hcl strengthens nerves, muscles, and heart function in addition to regulating blood sugar.

D-biotin in nighttime Phen24 functions as an enzyme to promote the breakdown of food, while molybdenum eliminates toxins to help improve metabolism. Glucomannan promotes fullness and appetite suppression, while green tea extract accelerates metabolism. And lastly, hops extract also promotes metabolic rate and supports quality rest.

Does it work?

The thorough evaluation shows that Phen24 is one of the best fat burner supplements for a reason. The 24/7 round the clock innovative process allows users to activate their metabolism and make sure it works even when they’re asleep. This mechanism of action is unique and impossible to find elsewhere in this format.

Since it keeps the metabolism working throughout the day, Phen24 helps users achieve their body goals almost effortlessly.

Phen24 is not just about weight loss; it also supplies the body with important vitamins and minerals we need for good health and wellbeing. Moreover, the supplement works to promote calmness and get rid of stress. This is particularly important if we bear in mind that high-stress levels can lead to weight gain, mood swings, slow metabolism, irregular sleep pattern.

What you should consider before buying a Fat Burner?

Many women are worried about choosing a fat burner because they don’t want to end up with the wrong product. You can easily find the best belly fat burner when you know what factors to take into consideration. Check them out below.


The first thing to check should be the label or the list of ingredients. The formula tells exactly what you will experience when buying that product. Also, taking a look at the ingredients helps avoid potential allergies if you have them. Make sure to choose the best fat burner for women if you’re looking for something gender-specific or go for unisex. It’s ideal to go for a fat burner with a powerful formula intended to boost metabolic rate and suppress your appetite.


Not all fat burners are equal, so you also need to consider the type. Different types include thermogenic fat burners, stimulant-free fat burners, appetite suppressants, carb burners, fat blockers, thyroid regulating fat burners, and cortisol-blocking supplements. Based on your needs and health status, choose the type that your body needs the most. For example, if overeating is your problem, then appetite suppressants are a solution. If you struggle to shed excess fat, then thermogenic fat burners could do the trick.


The formula is not just about the ingredients per se, but whether the product delivers a single ingredient or a blend of more of them. This factor depends entirely on your preferences and budget. Usually, blends have multiple mechanisms of actions while single-ingredient products just one, although its effects are more amplified.


The budget plays an important role in the process of choosing the best fat burners. Determine how much money you can spend on this product to eliminate all products that don’t match this criterion. Then, carefully evaluate different options to get the best value and the strongest effects for your money.


Dietary supplements come in different forms, and fat burners aren’t exceptions. They come in the form of tablets, capsules, softgels, even powders. Take some time to think about which format you find the most practical.

Dosage instructions

Some fat burners are taken once or twice a day while others even more than that. Check the label or instructions on the website to see how often you need to take the supplement. Do you find the instructions practical enough to adhere to them regularly? If so, that’s the product you need.

Your goal

The body goal you want to reach is an important factor to consider when choosing a fat burner. Do you just want to burn fat? Or maybe you’d want to retain or increase muscle mass? Think about your wishes and go for a product that can meet them.

User reviews

Experiences of other people can help rule out products that are considered highly ineffective. This will narrow down your choice to the ones that truly work. Focus on the reviews and testimonials posted by people whose story and goals match yours.

How do the fat burner supplements work?

Fat burner supplements do exactly what their name says – they burn fat. While the exact mechanism of action may vary from one product to another, the principle is the same – these products work to accelerate metabolism and thereby help burn more calories and fat.

The fat burners promote the thermogenesis process i.e., elevate body heat to provide effective fat burning effects. By supporting thermogenesis and speeding up metabolism, fat burner supplements allow the body to use fat to produce energy more effectively.

Many of these products also work to suppress appetite and curb cravings, improve athletic performance through energy boost, and exhibit other important effects such as blood glucose management, improved breakdown of food.

How can you get the best out of a fat burner for weight loss?

Since fat burners are dietary supplements whose formula consists of natural ingredients, they are considered safe for consumption. Side effects are rare, but when happening, they usually include nausea, constipation, abdominal pain, headache, higher blood pressure, and increased anxiety.
