The Top Metabolism Booster Supplements – Ranking Criteria

Though all metabolism-boosting supplements claim to support your metabolic health, not all work as advertised. To separate the best metabolism-boosting supplements from the worst, we considered the following factors:

Honest Advertisement

Some products tend to make exaggerated claims, like helping you lose 30 pounds in less than seven days without exercise or diet. While compiling the list of the best metabolism-boosting supplements, we were particularly wary of products offered by companies that make such unrealistic claims. All metabolism booster supplements on our list claim to promote weight loss when used in conjunction with specific dietary and lifestyle modifications. Though some products on our list claim to help you lose weight without strenuous workouts and low-calorie diets, they don’t claim to work in the absence of minor dietary modifications.


Some metabolism-boosting supplements use proprietary formulas to hide central nervous systems (CNS) stimulants like caffeine or low doses of other ingredients. While preparing the list, we preferred products with complete ingredients disclosure. Some products on our list do not have their entire ingredient label disclosed, and they are backed by hundreds of positive customer reviews online.

Scientifically-proven Ingredients & Dosages

Certain ingredients have been scientifically proven as metabolism boosters like green tea extract and caffeine. Hundreds of clinical trials have verified the efficacy of these ingredients in supporting metabolic health. While preparing the list, we preferred products that contain safe, well-researched, and clinically-supported metabolism boosters. All products on our list contain science-backed ingredients that increase your metabolic rate, improve calorie burning, and promote weight loss.

Manufacturer Reputation

As the supplement space is saturated with scams, you are very likely to come across fraudulent companies selling low-quality products. While preparing the list, we preferred companies with a track record of creating and selling high-quality health and wellness products. We were particularly wary of companies that sell overpriced formulas with no clinical backing. All products on our list come from highly credible manufacturers.

Formula Development

The best metabolism boosters are supported by accurate clinical information and are also formulated by health professionals. While marketing experts develop some supplements, some are formulated by physicians, naturopaths, nutritionists, and other medical professionals. We preferred metabolism-boosting supplements formulated by doctors while preparing the list.

Money-back Guarantee

A money-back or other satisfaction guarantee is symbolic of the manufacturer standing behind their product. The effectiveness of a metabolism-boosting supplement may vary from person to person due to different physiologies. With a money-back guarantee, you can get a full refund if you are not satisfied with the product.

Who Should Take a Metabolism Booster Supplement?

Anyone trying to improve calorie expenditure, burn excess fat, or lose weight can take a metabolism booster. Metabolism boosters are meant to increase your metabolic rate, the number of calories you burn at rest. If you burn 1,500 calories per day at rest, you can raise your calorie expenditure to 1,800 by taking a metabolism booster. This means that you don’t have to spend hours at the gym, doing cardio and other strenuous exercises.

Metabolism boosters can be incorporated into all types of weight-loss regimens. If you are struggling to shed the last few pounds of stubborn fat from your upper arms, belly, thighs, or butt, you should take a metabolism-boosting supplement to make your job easier.

Metabolism Boosters Side Effects

Metabolism-boosting supplements do not cause any significant side effects if administered according to recommended dosage instructions. However, supplements containing stimulants may cause side effects like anxiety, jitters, restlessness, and sleep problems, among others.

A user may experience side effects like stomach discomfort, digestive problems, headaches, and other mild symptoms if taking metabolism boosters in large doses. These side effects are rare and only emerge if you do not follow the recommended dosage instructions. People suffering from severe metabolic issues should consult a physician before taking a metabolism-boosting supplement.

Scientific Evidence for Metabolism Booster Supplements

Though boosting metabolism sounds like a vague goal, certain ingredients have been associated with promoting metabolic health.

There’s a decent chance that you already take a natural metabolism booster every day, such as caffeine. Caffeine is found in a wide range of metabolism-boosting supplements, weight loss aids, and diet pills. According to a study conducted in 1980, caffeine could significantly raise your metabolic rate shortly after its ingestion. In this study, researchers gave participants caffeine or a placebo and then asked them to engage in some sort of physical exercise. They found out that the metabolic rate of participants assigned caffeine increased considerably three hours after taking caffeine. It was concluded that caffeine could increase fat oxidation, helping your body convert more fat into energy.

As reported by Harvard Health, four cups of coffee per day are linked to modest fat loss. In one study that continued for 24 weeks, researchers gave four cups of coffee or a coffee-like placebo drink every day to 126 obese adults. The study concluded that regular coffee intake over 24 weeks could lower the risk of diabetes and help shed a modest amount of fat.

Green tea has also been associated with fat-burning. Many people consume green tea regularly to promote weight loss. According to a study conducted in 2013, regular intake of green tea can significantly decrease body weight, body mass index (BMI), and blood pressure in diabetic individuals. In this study, researchers gave green tea to a group of diabetic patients for eight weeks.

Green tea supplements are often advertised as metabolism boosters. Recently, Women’s Health magazine described green tea as a weight-loss agent. Similarly, Dr. Oz claimed that a particular green tea supplement could boost metabolism by 12%. These claims have also been backed by science. There’s ample scientific research that shows that green tea can improve your metabolic health, allowing you to lose weight efficiently. According to a study conducted in 2009, catechins present in green tea like epigallocatechin gallate or EGCG can help boost metabolism. About 49 clinical studies were analyzed as a part of this research.

Some metabolism-boosting supplements contain minimal doses of brown seaweed extract and kelp extract, both of which are infused with potent antioxidants. Due to the antioxidant properties of these ingredients, they are used to induce thermogenesis, a process that causes your body to burn fat. Kelp extract has been proven to help with lipid metabolism, fat burning, and weight loss.

In one study conducted in 2011, some of the best fat-burning supplements available on the market were analyzed. Researchers found that supplements that contained green tea and caffeine were backed by more evidence and positive customer reviews. Additionally, several other ingredients in fat-burning supplements were analyzed, including fucoxanthin, forskolin, kelp, conjugated linoleic acid, and chromium. Researchers did not find a lot of evidence corroborating the fat-burning properties of these ingredients.

A study was conducted in 2012 to analyze hundreds of weight loss supplements. The study concluded that no single product could cause significant weight loss. Researchers also found that many products contained harmful ingredients that could adversely impact the health of consumers. Nonetheless, researchers found that green tea formulas, fiber supplements, and low-fat dairy products produced significant but small weight changes when administered for weeks.

According to a recent study published in the journal Science, metabolism may not slow down with age. In this study, researchers found that metabolic rate remained balanced between ages 20 and 60, not fluctuating as generally believed. Researchers also found that babies have a 50% faster metabolic rate than adults. Researchers concluded that the metabolic rate drops by 3% every year until you turn 20. After 20 years of age, your metabolic rate tends to remain stable until you are 60. After the age of 60, your metabolism tends to drop 1% every year.

Furthermore, metabolism boosters add to the effect of your workouts and diets. According to a study conducted in 2011, you can keep your metabolic rate up for 14 hours by exercising for 45 minutes daily. Researchers found that exercising for 25 minutes every day could enable people to burn extra calories for the next 14 hours. Similarly, another study conducted in 2012 concluded that you could boost your metabolism through strength training. As muscle burns more calories than fat, strength training can be used as a sustainable way to boost metabolism.

Overall, you cannot sustainably boost your metabolism by just taking nutritional supplements. The best way to boost your metabolism is to make dietary and lifestyle modifications that support your metabolic health.

Frequently Asked Questions About Metabolism

We get zillions of questions about metabolism-boosting supplements every day. Here are some of the most frequently asked questions about metabolism boosters:

Q: What is metabolism?

A: Metabolism constitutes a series of biochemical processes within your body that are responsible for breathing, digestion, muscle building, blood circulation, and fat storage, among other things.

Q: What is the metabolic rate?

A: Metabolic rate is the amount of energy you spend over a particular period. It is the number of calories you need to keep your body functioning at rest.

Q: How can I increase my metabolic rate?

A: The most effective and easy way to increase your metabolic rate is exercising. As you exercise, you force your body to burn more calories. Alternatively, you can also use metabolism-boosting supplements to raise your metabolic rate.

Q: Does diet affect the metabolic rate?

A: Yes, diet and exercise habits play an essential role in your metabolic health. Your metabolic rate is also affected by other things like hormone levels, gender, age, menstruation, and pregnancy.

Q: How is metabolism different from catabolism?

A: Catabolism constitutes energy-burning processes that break down substances for energy. On the other hand, metabolism is a series of biochemical processes responsible for keeping your body functioning at rest.

Q: How is metabolism regulated inside my body?

A: Your metabolism is regulated by your thyroid. Your thyroid secretes hormones that influence body temperature, blood pressure, heart rate, and energy production.

Q: How does hypothyroidism affect my metabolic health?

A: People with hypothyroidism have lower levels of thyroid hormones in their bodies. As the condition aggravates, the hormonal imbalance may trigger a metabolic decline.

Q: Do lean people have a faster metabolism?

A: Lean people tend to have a higher metabolic rate than obese people. Your body requires about six calories per day to maintain a pound of mass. However, it only needs two calories a day to retain a pound of fat. Your body needs to burn more calories if you have more muscle than fat.

Q: Do men tend to have higher metabolic rates than women?

A: Yes, men have higher metabolic rates than women. This is because they have more muscle than fat. As muscle burns more calories than fat at rest, men tend to have higher metabolic rates than women.

Q: What foods should I eat to boost my metabolism?

A: You should eat high-protein foods to boost your metabolism as your body requires more energy to break down proteins. However, it is not healthy to consume excessively high levels of protein.

Q: Does metabolism slow down with age?

A: Yes, metabolism slows down as you get older. However, some recent scientific research says that it stays stable from 20 to 40 years of age. Usually, metabolism seems to slow down as you enter your 30s. Some scientific evidence suggests that your metabolic rate drops by 5% every year after 40. As you get older, you tend to lose muscle and gain fat, lowering your metabolic rate. Additionally, aging impacts your thyroid gland, causing hormonal imbalance and affecting metabolism.

Q: Does a low-energy diet boost metabolism?

A: No, a low-energy diet does not boost metabolism. On the contrary, it restricts calorie intake. If you consume fewer calories, your body enters starvation mode, which further lowers your metabolic rate.

Q: Does intermittent fasting affect metabolism?

A: Yes, intermittent fasting tends to slow down your metabolism. If you want to boost your metabolism, you should eat healthy meals or snacks every 3 hours. If you skip meals or take a low-calorie diet, your body enters ketosis. Ketosis constitutes a starvation mode that slows down your metabolism.

Q: Can I boost my metabolism by drinking water?

A: Yes, you can boost your metabolism by drinking plenty of water. Dehydration can adversely impact your metabolic health.

Q: Does exercise improve metabolism?

A: Yes, exercise improves metabolism. By engaging in physical activities every day, you can boost your metabolism significantly. By doing aerobic exercises daily, you can keep your metabolic rate up hours after the workout. Similarly, strength training exercises boost metabolism by helping you build more muscle mass.

Q: Can slow metabolism make me overweight?

A: Though overweight people tend to have a slower metabolism, they are not overweight because of metabolic issues. If you have a slow metabolism, it may be harder for you to lose weight. However, a sluggish metabolism cannot make lean people overweight. Obesity is associated with genetics, family history, medications, diet, and other lifestyle factors like poor sleep.

Q: What is thermogenesis?

A: Thermogenesis constitutes the release of energy by the production of heat. It involves a series of processes within your body tissues like skeletal muscle and brown adipose tissue. Most metabolism boosters are specifically designed to promote thermogenesis, making it easier for you to burn calories and lose weight.

Q: What should I eat to boost my metabolism?
