Boosting your metabolism is the easiest way for you to lose weight. Your metabolism refers to a series of natural bodily processes in which you burn fat, expend calories, and convert stored fat or carbs into usable energy.
Today, hundreds of supplements act as natural metabolism boosters for losing weight. These supplements use natural ingredients to improve your metabolic rate, which allows you to lose weight by increasing your daily calorie expenditure.
Although every metabolism booster claims to help you lose weight, it is proven that some work better than others. Many don’t work at all. To make your life easier, we researched hundreds of metabolism boosters to discover which were the very best and which were poorly formulated or ineffective.

Who Should Take a Metabolism Booster?
Realistically, anybody trying to lose weight, burn fat, or increase their calorie expenditure can benefit from taking a metabolism booster.
Metabolism boosters primarily work by increasing the rate your body burns calories, also known as your basal metabolic rate. If, for example, you burn 1,500 calories per day on average, using a metabolism booster can increase this number up to 1,800 calories per day. This means you can potentially lose more weight or won’t have to work out as hard to lose the same amount of weight.
If you fit any of these categories, then taking a metabolism booster might be of extra benefit:
- People struggling to burn their last few pounds of stubborn fat
- Anyone who has hit a weight loss plateau
- People just starting a diet or their weight loss journey to manage calorie intake
- People who want to burn off some fat without losing money
- Those looking for an extra boost in weight loss
How We Ranked the Best Metabolism Boosters
Although every metabolism-boosting supplement will claim to increase your metabolic rate to help you lose weight, not every supplement can back up these claims.
To separate the very best metabolism boosters from the imposters, we used several ranking factors, including the following:
Science-Backed Ingredients & Dosages
Several natural ingredients, such as caffeine and green tea extract, are clinically proven to support your metabolism. These ingredients have been repeatedly shown in numerous clinical trials to improve your basal metabolic rate, increase thermogenesis, and help support weight loss. The absolute best metabolism boosters will use science-backed ingredients along with dosages that were clinically proven to provide real metabolic improvements.
Ingredient & Dosage Transparency
Too many supplement companies hide their ingredients and formulas behind a “proprietary formula.” Sometimes, they hide stimulants in their formula to fool you into thinking that their products can work. The best metabolism boosters were transparent with their ingredients and each ingredient dosage. You should avoid products that hide behind these proprietary formulas.
Doctor or Physician Formulated
Some of the best weight loss supplements are formulated by medical experts or have a medical advisory board to back their products. The more we saw medical experts supporting a product, the better we ranked the product because it is a sign it is more likely to be both safe and effective for you.
Honest & Reasonable Advertised Benefits
Some metabolism boosters will claim they can help you lose 25lbs in the first month without making any changes. Others support healthy metabolic function and weight loss when used with a healthy diet and lifestyle habits. If a metabolism booster makes wild unrealistic claims, the product should be avoided. Chances are, they’re trying to deceive you and are likely ripping you off.
Company Reputation & History
Unfortunately, the weight loss supplement industry has a poor history of dangerous or ineffective products. Some of the best metabolism boosters come from companies with a proven record of creating high-quality metabolism-boosting products.
Price & Value
Metabolism boosters can vary wildly in price. You can find some for as little as $25 or as much as $200. While we didn’t discriminate against higher-priced products, we still wanted to find the best metabolism boosters to fit any individual budget. This is why you’ll see our best metabolism boosters are attractive at various price points.
The best metabolism boosters offer an explicit money-back guarantee to show that they back their products. If a product doesn’t work for you, you should be able to get your money back in a reasonable time. No supplement has a 100% success rate, so you should receive your money back if you don’t see results or experience unwanted side effects.
The best way to determine the best metabolism boosters is to read the customer reviews. This is the only authentic way to get an idea of the average experience of the customer.
We reviewed thousands of customer reviews while ranking our best products.
Science Behind Metabolism Boosters
You may be confused about the phrase “boosting your metabolism.” After all, it is a vague goal. However, some ingredients have been proven to improve your metabolic function to help you lose weight.
You might already take one of the most well-known metabolism boosters every day – caffeine. Hundreds of studies have proven that caffeine can enhance metabolic function. This is why caffeine is arguably the most common ingredient added to weight loss products, metabolism boosters, and diet pills.
In a study back from 1980, researchers analyzed the effects caffeine had on metabolism. In this study, participants were either given a low dose of caffeine or a placebo, then told to exercise. Researchers discovered that the overall metabolic rate increased significantly for three hours after ingesting caffeine. It also enhances fat oxidation, which helps your body burn more fat and convert it into usable energy.
Harvard Health has published research that upwards of four cups a day are associated with body fat loss. In one 6-month study, 126 overweight adults were given four cups of coffee or a coffee-like placebo daily. The coffee group was observed to lower the risk of developing diabetes and was associated with a fair amount of body fat loss.
Next to caffeine, the most common metabolism-boosting ingredient is green tea extract. Millions of adults consume green tea extract each morning for weight loss. Studies have found it can lead to significant weight loss too.
For example, in a 2013 study, researchers found that green tea extract could lead to a significant decrease in body weight, BMI, and blood pressure in a group of adults that had diabetes in just eight weeks.
Many metabolism booster supplements advertise specific metabolism-boosting benefits with their product. For example, Dr. Oz claimed his green tea supplement could boost metabolism by 12%. Another publication – Women’s Health Magazine, described green tea as “weight loss magic.”
The primary mechanism behind green tea’s metabolism-boosting effects is a group of chemicals called catechins. The primary catechin is known as epigallocatechin gallate or EGCG. In a 2009 study, researchers found that EGCG could significantly affect body composition and weight loss. A meta-analysis of 49 individual studies on green tea extract also confirmed these benefits.
Other metabolism supplements contain brown seaweed extract or kelp. Studies have found that these metabolism booster supplements have strong anti-inflammatory properties and stimulate thermogenesis, which requires you to burn calories to create heat.
Plenty of proven ingredients support metabolic function, but a 2011 study researching nutritional supplements found that caffeine and green tea extract were the most proven metabolism boosters. They had more evidence than any other individual ingredient, but some proven ingredients include forskolin, CLA, kelp, fucoxanthin, and chromium.
To maximize your results, you have to pick the right metabolism booster. Studies have found that not all metabolism boosters are the same. In a 2012 study involving hundreds of weight loss supplements, researchers found that no evidence exists that any single product can result in significant weight loss. They also found that many popular products had potentially detrimental side effects. However, they still noted that green tea formulas, fiber supplements, and other products could result in decent weight loss.
Although metabolism supplements can help, studies have found the absolute best way to increase your metabolism is by vigorously exercising. A 2011 study confirmed that 45 minutes of strenuous exercise increased metabolic rate up to 14 hours. After the 45 minutes of exercise, researchers found that adults burned extra calories for roughly 14 hours beyond what they would generally burn when not exercising.
Strength training has also been shown to support metabolic function. Muscle burns more calories per day than fat, so building muscle mass is an easy way to burn extra calories and keep off any weight that you may lose.
Side Effects of Metabolism Boosters
Metabolism booster supplements are typically safe products and are tolerated well when used by healthy adults in standard dosages. In general, you should not expect to experience any side effects while using a metabolism booster.
However, some of the products contain stimulants, which could have side effects. Caffeine, for example, is known to cause jitters, anxiety, restlessness, trouble sleeping, and other side effects.
Any supplement has the potential to cause side effects – especially if dosages are too large. It can experience digestive issues, stomach pain, headaches, nausea, or other symptoms. This is why it is essential to follow the recommended dosage instructions on the label of your metabolism booster to reduce the likelihood of experiencing side effects.
Unfortunately, there is no recommended dosage for metabolism boosters. Some ingredients have specific dosages that have been proven to be safe and effective. For example, caffeine usage should be limited to 200 to 300mg. Otherwise, there’s a good chance you may experience the adverse side effects of the stimulant.
Metabolism Booster Supplements FAQs
We’ve got plenty of questions about metabolic function and metabolism-boosting supplements. We’ll answer your most commonly asked questions to clarify your most pressing issues.
Q: What is metabolism, and what is the metabolic rate?
A: Your metabolism is a series of bodily processes responsible for your breathing, fat storage, digestion, circulation, muscle building, and much more.
Your metabolic rate refers to the rate at which your body burns calories when performing certain activities or at rest. For example, your body has a higher metabolic rate when exercising than when sleeping.
Q: What affects metabolic rate?
A: Virtually everything related to your health will affect your metabolic rate. Your diet and exercise are the two most important factors that affect your metabolic rate. In addition, your age, sex, hormone levels, pregnancy, sleep habits, alcohol use, and other environmental factors can also influence your metabolism.
Q: What regulates metabolism?
A: Your thyroid gland regulates the body’s metabolism. It produces hormones directly responsible for controlling your metabolism and things like heart rate, body temperature, blood pressure, breathing, and more.
Hypothyroidism is a condition in which your thyroid does not function properly. Your thyroid does not produce enough hormones as much as it should. As a result, your metabolism suffers, and you may experience unexpected weight gain.
Q: How can I raise your metabolic rate?
A: As a result of slower metabolism, your body burns fewer calories and struggles to produce fat-burning hormones. Studies have found the best way to raise your metabolic rate is by exercising, which forces your body to consume more energy and burn more calories. Alternatively, you can take these dietary supplements to support your metabolism further.
Q: What is my resting metabolic rate (RMR)?
A: Your resting metabolic rate is the total number of calories burned when resting or engaging in normal daily activities. It differs from BMR because resting metabolic rate (RMR) accounts for everyday activities like walking around your home, cleaning, or other low-intensity activities.
Q: What is my basal metabolic rate (BMR)?
A: Basal metabolic rate is the number of calories you burn to sustain essential life-sustaining functions. It supports breathing, circulation of blood, organic function, and neurological functions. It is also proportionally related to lean body mass and decreases .01kcal/min for each 1% increase in fat percentage.
Q: What are anabolism and catabolism?
A: Anabolism and catabolism refer to the two main components that make up your metabolism.
Q: Do men have a faster metabolism than women?
A: Men tend to have a higher metabolic rate than women because men often have more muscle and less fat. Muscle also burns more calories per day than fat, so it is only natural that men may have a naturally higher metabolic rate.
Q: Do lean people have a faster metabolism?
A: People with more muscle mass tend to have a high resting metabolic rate than those who are heavier. Your body needs around 6 to 8kcal a day to maintain muscle mass, but it only needs 2kcal a day to keep a pound of fat. Therefore, lean people have a faster metabolism than those with a higher body fat percentage, although not always the case.
Q: Can foods affect metabolism?
A: Certain foods have been shown to improve metabolism. The best foods to increase metabolism are protein-rich foods. This is because the body needs to expend more energy to break down proteins.
When you combine protein-rich foods with your balanced diet and exercise program, you can increase metabolism and control your blood sugar levels.
Hot peppers have also been shown to have metabolism-boosting properties. Hot peppers contain capsaicin, which has thermogenic effects on the body. So, you can also eat spicy foods and burn more calories.
Q: Will exercise improve my metabolism?
A: Exercise is one of the absolute best options for burning fat and boosting metabolism. Cardiovascular exercise stimulates your metabolism for up to 14 hours after your workout. In addition, lifting weights can boost metabolism and help you build lean muscle mass. Since muscle burns more calories than fat, building muscle can improve your basal metabolic rate.
Q: Does age affect metabolism?
A: Previously, it was thought that metabolism slowed down after the age of 30. However, new research suggests that metabolism stays relatively stable between the ages of 20 and 60. Once we turn 60, we typically see a decrease in metabolic rate by about 1% per year. However, metabolism is still at its’ height as a baby through the teenage years.
Q: Do genetics and hormones play a role in metabolism?
A: Hormones can play a significant role in your metabolism. Leptin and insulin, sex hormones, and growth hormones can influence your metabolism, body fat distribution, appetite, and much more.
Likewise, genetics also plays a role in metabolism. Genetics can influence multiple aspects of your physiology, which means genetics can make it easier or harder for you to lose weight.
Q: Can intermittent fasting enhance metabolism?
A: Intermittent fasting has been shown to boost metabolism slightly. The body enters ketosis after around 14-16 hours of not eating. This causes the body to break down fat and convert it into usable energy.
Q: What else can affect metabolism?
A: Stress can temporarily alter your body’s metabolic rate once it initiates its’ flight or fight response. This raises cortisol levels, which causes your body to have stored fat. However, temporary stress can increase your metabolism slightly.
Sleep habits and water consumption can also affect metabolism. Drinking ice-cold water has been shown to raise your metabolism and burn more calories temporarily. Your body produces hormones that influence metabolism when you sleep, so healthy sleep habits are needed to keep your metabolism functioning properly.
Q: Does a slow metabolism cause weight gain?
A: In general, most overweight people are so because of their diet and lifestyle factors – not because of their metabolism. However, being overweight can slow down your metabolism, making it more challenging to lose weight. Fat burns fewer calories per day than muscle, making weight loss more difficult. However, most weight gain is associated with poor diet, not exercising, genetics, family history, lifestyle habits, and medications.
Q: How can I boost my metabolism?
A: The best ways you can increase your metabolism is to lift heavy weights, eat a healthy diet, get plenty of sleep, drink water, and follow other healthy lifestyle habits.
Q: What is thermogenesis?
A: Thermogenesis is a process in which your body produces heat. To do so, it needs to burn off energy (calories). Thermogenesis happens in your brown adipose tissue and skeletal muscle. Many metabolism-boosting supplements are specifically formulated to induce thermogenesis to help you lose weight.
