If you’ve had trouble losing weight despite your best efforts with diet and exercise, you may benefit from metabolism booster pills.
These supplements use natural ingredients to speed up your metabolism, helping you burn fat and lose weight quickly. Like with all weight loss aids, a lifestyle change is usually necessary to keep the lost pounds off.
Ingredient concentration determines the potency and efficacy of metabolism supplements. Here’s a quick overview of the best products we found.
Best Metabolism Boosters
Out of dozens of metabolism booster pills on the market, we have chosen these top eight dietary supplements for several key reasons. Each contains evidence-based ingredients for losing weight by burning fat, protecting and enhancing muscle, reducing cravings while improving motivation, and slowing carbohydrate absorption so you consume fewer calories.
1. PhenQ – Best Metabolism Booster Overall
Targets fat metabolism with several thermogenic ingredients.
Comes with energy-boosting ingredients to aid exercise.
Blood sugar support.
Reference a list of academic articles to back up each product ingredient.
60-day money-back guarantee.
Cons of PhenQ
Contains caffeine, which can cause insomnia, nausea, and restlessness for some.
Who Is PhenQ Best For?
PhenQ is the best overall metabolism booster with several mechanisms of action to help promote weight loss. It is ideal for most people, unless there are any allergies or contraindications with other medication.
PhenQ contains several ingredients with their own sets of benefits: alpha-Lacys Reset, Capsimax (a blend of caffeine, piperine from black pepper, vitamin B3, and capsaicin), chromium picolinate, caffeine, nopal cactus, and L-carnitine.
Alpha-Lacys Reset, made of alpha-lipoic acid and cysteine, is claimed to promote weight loss, reduce body fat, and increase muscle mass. Alpha-lipoic acid alone has shown a slight but significant effect on body weight and BMI, while reducing waist circumference by 2 centimeters (almost 0.8 inches) in unhealthy volunteers .
Additionally, capsaicin is an anti-inflammatory that increases fat burning for heat energy; while L-carnitine starts the process of fat burning by shuttling fatty acids into the mitochondria, your cellular powerhouses  . Caffeine may help to prevent weight regain, while chromium picolinate aids blood sugar control, and vitamin B3 aids youthful energy production  .
Nopal cactus, or prickly pear, may have a more unique profile of benefits when it comes to weight loss supplements. Laboratory research suggests it can prevent a gain in stored fat even during periods of overeating, while controlling blood glucose.
It may also reduce inflammation and improve metabolism by increasing the diversity of the gut microbiome. Gut bacteria play a range of roles in the control of inflammation and immunity, neurotransmitter production, and metabolism. Additionally, relief of inflammation can soothe fatigue, giving you more energy to exercise and for everyday life .
Who Should Avoid PhenQ?
People with a sensitivity to caffeine may be best avoiding PhenQ, as it contains caffeine as a stand-alone ingredient and in the Capsimax blend. Additionally, those taking blood sugar-lowering medication may experience an additive effect with chromium. Clenbutrol would probably be a better option in such cases.
PhenQ is one of the best metabolism boosters on the market. Its ingredients virtually cover all of the bases when it comes to burning fat more efficiently, including blood sugar and appetite control.

2. Instant Knockout – Best Metabolism Booster For Men
Several thermogenic ingredients for maximum fat-burning power.
Glucomannan to control food cravings.
Vitamins B6 and B12 for healthy neurotransmitter production.
Protection of muscle with piperine.
Men’s health support with zinc.
Who Is Instant Knockout Best For?
Instant Knockout is one of the most potent fat burners for men, with the assurance that muscle mass will be maintained. Two of its mechanisms of action are controlling cravings and increasing fat oxidation, with the added benefit of protecting your muscles against oxidative damage from heavy exercise.
L-theanine has both calming and metabolism-stimulating effects. Vitamins B6 and B12 are used in the production of mood-regulating neurotransmitters, which may relieve stress-induced cravings too. If you overeat because of stress, L-theanine and B vitamins may be a healthier substitute.
L-theanine can regulate serotonin and dopamine production, which affect mood and the perception of reward. It also prevents an accumulation in body fat, and increases the rate at which you burn fat .
Capsaicin and black pepper can increase sugar and fat burning for energy, while increasing insulin sensitivity and offering anti-inflammatory benefits. However, piperine helps to protect your lean muscle mass against the often damaging effects of high-intensity exercise.
Lab studies show that piperine increases carbohydrate and fat metabolism, while enhancing the production of your body’s own antioxidants. The inflammatory response was not activated, and the level of oxidative stress did not rise. Piperine allowed muscle tissues to have the best of both worlds: less damaging oxidative stress, but more available energy .
Who Should Avoid Instant Knockout?
Instant Knockout is not for you if you take NTI medication as the glucomannan content may reduce absorption. If you use other medications or supplements where dosage has a wider window for safety and efficacy, it is best to separate Instant Knockout from them by several hours. Clenbutrol would be a great alternative if you’re on NTI medication.
Instant Knockout can help you lose weight by taming cravings and boosting your ability to burn fat, but without your muscles being affected as collateral damage. The protective antioxidant piperine gives it an extra edge by preventing muscle damage.

3. PhenGold – Best Metabolism Booster For Energy
Green coffee, green tea, and caffeine to boost metabolism.
Rhodiola for energy and motivation.
Tyrosine for thyroid hormone support.
100-day money-back guarantee after at least 50 days of use.
Who Is PhenGold Best For?
PhenGold is best for you if you struggle with scraping together the motivation to exercise. With 250mg of rhodiola extract, this supplement may increase the production of dopamine. Tyrosine, another ingredient, is the amino acid used as the backbone for thyroid hormones (which boost metabolism too) and for dopamine and adrenaline.
Dopamine boosts motivation by raising the level of effort we’re subconsciously willing to make in order to achieve a goal, and provides a sense of reward. It may therefore prevent sugar cravings too, as you don’t need a quick fix for a feeling of being rewarded .
The green coffee extract included in PhenGold adds to the benefits of caffeine and L-theanine. It may reduce the amount of fat tissue in the liver, making it beneficial if you have non-alcoholic fatty liver disease.
Green coffee bean extract can prevent gains in body fat by inhibiting the function of fat cells, while improving insulin sensitivity and liver function. Some of its effects are through increasing AMPK function, a gene that triggers fat burning instead of fat accumulation .
Who Should Avoid PhenGold?
PhenGold contains tyrosine, the backbone of your thyroid hormones and dopamine.
If you have an underactive thyroid or take Adderall, tyrosine may have an additive effect with your medication and elevate your thyroid hormone or dopamine levels too much. There may be a risk if taken alongside other dietary supplements that increase thyroid hormone too. PhenQ may be a better option in such cases.
PhenGold combines a range of energy-boosting ingredients, which may enhance dopamine and adrenaline production while removing fat from not only under the skin and muscle, but also from inside the liver. However, tyrosine may be unsuitable if you have a thyroid condition.

4. LeanBean – Best Metabolism Booster For Women
Relieves cravings with satiety-promoting ingredients.
Blood sugar support.
90-day money-back guarantee.
Who Is LeanBean Best For?
LeanBean is best for women who struggle to lose weight due to overeating. It is designed to match the way womens’ brains respond to food and metabolism.
LeanBean’s main ingredient is glucomannan, an indigestible carbohydrate that soaks up water to form a barrier. This can not only reduce nutrient absorption, but also make you feel more satisfied and less likely to overeat. The amount used per dose is 3 grams, which EU health regulators recommend for an effective weight loss supplement based on the ingredient.
Glucomannan has prebiotic properties too, meaning it feeds the beneficial species of bacteria that regulate immune system balance, neurotransmitter production, and metabolism. Better neurotransmitter balance may relieve stress and cravings as a result .
Who Should Avoid LeanBean?
Women (and men) taking narrow therapeutic index (NTI) medications should avoid LeanBean and all products containing glucomannan. The coating that glucomannan forms over the stomach and intestinal lining may reduce absorption of your medication. Consider PhenQ in such a scenario.
LeanBean contains ingredients that effectively promote appetite regulation in women through a therapeutic dose of glucomannan. However, caution is advised if reducing absorption through the digestive system may reduce the effects of your medication.

5. Burn Lab Pro – Best For Muscle Mass Protection
Contains two metabolism booster supplements that stimulate muscle growth.
Piperine to ensure you lose weight from fat, not muscle tissue.
Chromium for improved blood sugar control.
Four-month supply bundle providing you with a 25% discount compared to the standard one-month supply.
Who Is Burn Lab Pro Best For?
Burn Lab Pro is best if you want to lose body fat, while ensuring that your muscle and strength remains protected. Whether you are a professional athlete or simply want to maintain fitness and quality of life, Burn Lab Pro may bring you the results you’re looking for.
The star ingredient in Burn Lab Pro is ForsLean, a form of the herbal remedy Coleus forskohlii. Its active phytochemical, forskolin, can stimulate thermogenesis and reduce fat mass in humans. Forskolin also increases muscle tissue, so you aren’t losing lean muscle as collateral damage .
Burn Lab Pro’s other muscle-boosting ingredient is beta-hydroxy-beta-methylbutyrate (HMB), which can boost your metabolism through increasing muscle tissue. HMB can even be effective in older adults struggling with health and fitness due to age-related muscle loss (sarcopenia). Left unaddressed, this may progress to frailty, a dangerous condition that increases the risk of falls and fractures.
Several clinical studies have focused on how HMB may benefit older adults, with clear signs of success. Two involving bed rest found a lower rate of muscle loss with HMB supplementation, and one of these found a higher rate of muscle gain during rehabilitation exercises.
A third involving healthier volunteers found a gain in muscle and protection of strength, while the control group showed a loss of strength over the 12-month study period. Altogether, these results show that HMB is effective in increasing or protecting muscle .
Who Should Avoid Burn Lab Pro?
As Burn Lab Pro contains chromium, we advise caution if you are taking medications or other supplements that lower blood sugar. Speak to your doctor for further advice and support when it comes to Burn Lab Pro or other dietary supplements.
Burn Lab Pro includes evidence-based ingredients that can help you preserve and increase muscle tissue, boosting metabolism both directly and indirectly through improved exercise capacity.

6. Trimtone – Best Metabolism Booster For Menopause
Contains grains of paradise for increased browning of fat.
Green coffee and green tea extract to boost your metabolism.
Best value bundle of five months’ supply for $149.99; at $1 per daily dose.
100-day money-back guarantee with orders of more than one month’s supply.
Who Is Trimtone Best For?
Trimtone may be best for you if stubborn fat is a significant issue, despite your balanced diet and exercise program. It doubles as one of the best fat burners for women.
Trimtone contains 40mg of grains of paradise extract, a higher dose than what has shown efficacy in clinical trials (30mg). In this study, women taking the extract lost more abdominal fat than the placebo group, which is a common site for unwanted fat to accumulate after menopause.
Grains of paradise is related to the ginger family, and stimulates the ability of brown adipose tissue to burn fat. Although a less common ingredient in metabolism booster supplements, grains of paradise may be particularly important if you have issues with insulin regulation, as it improves sensitivity .
Additionally, the chlorogenic acid and green tea extract in Trimtone may reduce carbohydrate absorption in the gut, as well as helping you lose weight by burning more calories.
In one study, green tea extract was shown to not only help participants lose weight, but prevent weight gain after supplementation ended. In another, green coffee bean extract allowed women to lose an average of 4.84 kilograms, compared to 2.62 kilograms among those taking a placebo alongside dieting  .
Who Should Avoid Trimtone?
If you are taking NTI drugs, or need certain dietary supplements because you are prone to nutrient deficiencies, it is best to avoid Trimtone and other supplements containing glucomannan. As each dose also includes 100mg of caffeine, you may prefer Clenbutrol if you are sensitive to coffee.
Trimtone targets several key mechanisms of controlling excess fat, making it a potentially effective thermogenic fat burner. Not only does it act as a metabolism booster through increasing brown fat activity and your overall ability to burn calories, but it also slows calorie absorption.

7. Prime Shred – Best Metabolism Pill For Older People
May boost metabolism by increasing energy production.
Contains niacin, which can reduce liver fat content while boosting energy.
Contains piperine to protect muscle tissue while losing weight.
100-day money-back guarantee.
Who Is Prime Shred Best For?
Prime Shred is best for you if you have fatty liver disease or are at risk of developing the condition. An estimated 25% of people in the world have fatty liver, which is linked to overweight and obesity. This and other complications are a significant reason why metabolism boosters are so important.
Niacin, vitamin B6, and vitamin B12 enhance fat-burning abilities in areas such as the liver. Prime Shred does not only act as a metabolism booster, but may relieve the complications of obesity while you are still losing weight. It still contains green tea extract, capsaicin, green coffee extract, and other thermogenic fat burner ingredients, but these aren’t its only focus.
A study of vitamin B6 in fatty liver disease found that supplementation reduced liver fat from 18.8% to 16.7%, despite the volunteers not significantly losing weight . Vitamin B6 reduces homocysteine, an inflammatory substance that promotes fat accumulation in the liver. Vitamin B12, another ingredient in Prime Shred, assists in lowering homocysteine too .
Besides its potential anti-aging benefits, niacin may be an effective remedy for fatty liver disease. In a study of people with diabetes who started a balanced weight loss regimen, those in the highest quarter of niacin intake lost the most liver fat, 37% of the organ’s total stores. High niacin intake was associated with a 77% greater chance of fatty liver disease resolution .
Who Should Avoid Prime Shred?
Prime Shred contains 225mg of caffeine, slightly more than two cups of coffee. If you are particularly sensitive to caffeine, you may want to opt for Clenbutrol.
Prime Shred goes beyond acting as a metabolism booster by relieving some complications of obesity while continuing to help you lose weight.

8. Clenbutrol – Best Metabolism Supplement For Belly Fat
Increases mitochondrial counts, leading to more energy production.
Added niacin to support new mitochondria.
60-day money-back guarantee.
Who Is Clenbutrol Best For?
Clenbutrol is the natural alternative to the pharmaceutical Clenbuterol metabolism booster pills. It is a safer way to lose weight, without the legal issues that come with drugs or hormonal fat-burning supplements.
Clenbutrol contains garcinia cambogia, a popular dietary supplement among those who want to burn calories more to lose weight. What also ranks garcinia among the best proven metabolism boosters is the ability to prevent carbohydrates from being converted into fat.
Garcinia is a versatile dietary supplement that can help you lose weight, or aid weight maintenance, through several mechanisms. It increases your ability to burn calories from fat, and reduces calorie intake by taming cravings. Garcinia aids weight loss by increasing serotonin, preventing overeating due to low mood .
Another key ingredient in Clenbutrol is the stimulant guarana, popular in energy drinks and metabolism boosters. The fat-burning benefits of guarana originate from its ability to increase the number of mitochondria inside cells. This leads to more energy production, making guarana one of the best fat burners as it enhances overall vitality .
Who Should Avoid Clenbutrol?
While some may feel great with the energy-boosting benefits of Clenbutrol, others can find guarana too overstimulating. In such a case, go with PhenQ.
Clenbutrol is one of the best metabolism booster pills to lose weight and feel great. The combination of garcinia, guarana, and niacin can lift mood, increase energy production capacity, and provide the necessary fuel for energy generation.

Best Metabolism Boosting Pills: Buyer’s Guide and What We Considered
There are several factors that helped us to choose the most high-quality metabolism booster supplements.
An effective weight loss supplement includes evidence-based ingredients. How well each individual ingredient works, along with whether they complement each other or simply have additive effects that may be too much of a good thing, are important concerns. Human studies are prioritized, as your metabolic processes are different to an animal.
The benefits claimed by the company can point to what their metabolism booster supplement can do for you. Their range of benefits, along with whether they are realistic and if the company lists references to academic research, are important points.
Ingredient side effects, and whether or not the supplement company discloses them, can make or break metabolism boosters. It’s no use taking the best metabolism booster pills around if their side effects worsen any health conditions you may have, or have effects that prevent you from exercising.
Independent customer reviews are an important gauge of how well a metabolism-boosting supplement works for real people in the real world. They are even more important if the product hasn’t been studied as a whole, as the formula of ingredients may work differently to what you might expect after simply adding each together.
Besides efficacy, factors such as taste (or size of the pill), customer service, and shipping times affect how convenient it is to use the brand’s products.
What if you’re on a budget, or your first choice of metabolism-boosting supplement isn’t right for you? The usual cost of supplements, including any bundles of several bottles, discounts and their conditions, and refund policies often determine if a product is cost-effective for you or not. This includes the cost per dose, as supplements can range from cents to several dollars per daily dose.
What Is Metabolism in the Body?
Metabolism encompasses all physical processes in the body, but most commonly refers to those that are involved in energy production. Energy enables all actions the body can do: movement, maintenance, growth, reproduction, and more.
The process of energy production starts with digestion, which breaks food into nutrient molecules. The macronutrients, carbohydrates, proteins, and fat, can be broken down further and used to generate energy, with carbohydrates the most efficient source.
A series of chemical reactions allows energy made during the breakdown of glucose to be stored in a carrier molecule, for use when the cell needs it. How well all of these steps work depends on hormonal factors, supporting nutrients, and the health of your mitochondria, parts of the cell where most energy is made .
How Do Metabolism Booster Supplements Work?
There are three main ways in which metabolism-boosting supplements work to help you lose weight:
Appetite suppressant effects.
Thermogenesis is the process of heat production. It involves a pathway where the mitochondria, your cellular “power plants,” can switch to generating heat in order to raise your body temperature. Both muscle and brown fat are capable of non-shivering heat generation, which is why you may hear about the importance of converting white fat tissue to brown fat.
Some metabolism boosters are chosen for their ability to increase your ratio of brown fat tissue. White fat only stores energy, but brown fat can generate energy and heat. As a result, more brown fat is linked to improved blood sugar control and a higher basal metabolic rate .
Other supplements boost your metabolism by enhancing energy production. Some of these speed up the process of breaking down fat and carbohydrates into fatty acids and glucose, so they can be burned for energy. Others can support the function of your mitochondria, by protecting them against oxidative damage or assisting in their repair or energy production pathways .
If overeating is an issue for you, supplements that also suppress appetite could be essential for weight maintenance to consume fewer calories. Food cravings may be an attempt to increase or substitute for a nutrient you’re deficient in, or can be the result of a hormonal imbalance.
While the hormone ghrelin stimulates hunger, leptin promotes feelings of satisfaction. Many overweight and obese people produce too much ghrelin and too little leptin, causing excessive food intake despite no real physiological need .
How to Speed Up Metabolism: Science-Backed Ingredients
Natural metabolism booster supplements commonly contain one or more of:
B vitamins, vitamin D, and other minerals.
Caffeine is the most popular stimulant in the world, and is also an effective addition in metabolism supplements. It increases the breakdown of fats into singular fatty acids, and the rate of cellular energy production. Caffeine is also a thermogen, producing both energy and extra body heat, and helps to enhance exercise performance.
Studies on weight loss have found that caffeine can help prevent weight regain. For example, high caffeine intake (the equivalent of three or more cups of coffee each day) is linked to a 16% weight regain, compared to 30% for low caffeine consumption .
Capsaicin produces heat in more ways than one. Besides being the source of heat in chili, it’s also a thermogen with a number of metabolic effects, including on the fat cells and pancreas.
Lab studies show that capsaicin increases the breakdown of sugars and energy production, while slowing the absorption of sugar through the intestinal wall. Animal research adds that it can relieve inflammation generated by fat in the body.
In humans, capsaicin can improve insulin sensitivity and reduce blood glucose, potentially improving the symptoms of metabolic syndrome. Other research shows that it may enhance cardio performance, helping you to increase your fitness. When you can start enjoying exercise, instead of struggling through it, healthy habits and a healthy body weight are easier to keep .
L-Carnitine (Amino Acids)
L-carnitine is a “conditionally essential” amino acid, meaning that your body can make enough for itself, but you may need supplementation in certain situations. Its main role is to move fatty acids into the mitochondria so they can be broken down for energy. If you have stubborn body fat, you may benefit from L-carnitine.
This role in energy production may also boost your exercise performance. A trial where men took L-carnitine supplements found that leg press weight and repetitions, along with power output during a spin bike test, significantly improved after nine weeks. Their antioxidant status was higher too, indicating a protective effect for the mitochondria .
Chromium picolinate is a popular supplement for the prevention and relief of diabetes. It may boost your metabolism by assisting the entry of glucose into cells, in order to start the process of energy production. These benefits may be more readily found in people with diabetes, as healthy adults have often shown no real effect.
Clinical studies show that chromium picolinate supplements can reduce blood sugar and insulin levels, indicating a lower level of need for the hormone as more glucose is entering the cells. The level of glycated hemoglobin fell too, which is the percentage of hemoglobin that has unabsorbed sugar “tangled” in it. Glycation can lead to increased inflammation and tissue damage .
Green tea has a number of metabolic health benefits thanks to a number of phytochemicals present, including caffeine and antioxidant compounds. It may inhibit fat digestion and absorption, while reducing the number of fat cells and having a thermogenic effect on the body.
Some antioxidants in green tea can boost the metabolic rate in brown fat tissue, while increasing insulin sensitivity and insulin production. As insulin levels often fall when sensitivity rises, this may mean you can benefit from green tea extract even if you’ve had diabetes for a long time .
B Vitamins, D Vitamins, and Other Minerals
B vitamins are essential nutrient cofactors that the mitochondria require for energy production, each with its own roles. Vitamins B1, B2, B3, and B5 support various steps in the Krebs cycle, which is responsible for the vast majority of cellular energy production. Vitamins B2 and B3 complete the process of energy generation.
The lesser-known vitamin B7 (biotin) is essential for fat oxidation, so fats and individual fatty acids can be burnt for energy. Although forms of vitamin B3 have become more popular in recent years thanks to potential anti-aging properties, it is best to take a supplement with all essential B vitamins .
How To Boost Metabolism With Easy Lifestyle Changes
There is no one-time, permanent fix to boost your metabolism. However, there are sustainable choices you can make that provide long-term benefits. A healthy diet and exercise program always have a place in your weight loss journey, regardless of how effective your supplements are.
Drink Plenty of Water
Drinking more water can play a role in boosting metabolism, especially if it is cold. A study of 14 healthy adults demonstrated that drinking 500ml of water could increase the resting metabolic rate by 30% .
Consume More Protein
Supplementation is no substitute for a healthy diet, for more reasons than calorie intake. To digest food, you need to burn calories, and different types of food require different amounts of calories burned. Protein-rich foods are more energy-intensive to digest than carbs or fat, as protein increases your metabolic rate by 15–30%.
This is a much larger effect than carbs, which only increase metabolism by 5–10%, or fat. Digesting fat means your body burns fewer calories than either protein or carbs, as it only requires a small 0–3% rise in metabolic rate .
Eat Spicy Foods
Eating more spicy food can have a slight, but significant effect on your ability to burn calories. A small study on young adults found that spicy foods such as red pepper could increase the number of calories burned by 10 per meal. It may not sound like much, but could translate to an extra pound of stored fat lost per year .
Add HIIT Training to Your Workout Routine
It sounds too good to be true, but high-intensity interval training (HIIT) could be more effective than long periods of endurance exercise.
Research suggests that, despite having a shorter duration, HIIT results in at least the same amount of calories burned because of a prolonged metabolism boost. This means you’re burning fat all day, even if you only spend half your regular amount of time exercising .
Include More Strength and Resistance Exercises
Whether you prefer HIIT or longer workouts, avoid focusing solely on cardio. Studies show that women who include strength training in their exercise routine prevent the loss of muscle while losing weight. Cardio exercise or no training led to a loss of muscle, and a fall in metabolism as a result .
Find a Reason to Stand and Move
Even something as simple as standing more can improve your ability to burn fat. If you replace sitting with standing while working at an office job, you can boost your metabolism to use up 174 more calories per day. The same study demonstrating these results also showed that the rate of high blood sugar was reduced by 43% .
Keep a Consistent Sleep Schedule
Although your basal metabolic rate falls during sleep, healthy sleeping patterns are essential for good metabolic health. A good night’s sleep regulates metabolic health by controlling blood sugar and the hormones leptin and ghrelin, which promote satisfaction and hunger respectively. As a result, you relieve food cravings and prevent weight gain .
