Do Metabolism Boosters Pills Work?
As metabolism booster pills are gaining popularity, the question of their efficacy comes into play. Do these magic pills actually work for weight loss, and can they actually boost your metabolism?
The way metabolism booster pills work is through a process called thermogenesis[1], or increased body heat production, which is a normal by-product of human metabolic processes. Through thermogenesis, your overall energy expenditure and resting metabolic rate increase and therefore more calories are being burnt. When the body heats up, it’s doing what it can to cool down, and during that process, it burns calories.
Metabolism booster pills and other metabolism booster supplements are usually created as a combination of different ingredients which have an effect on boosting your metabolism. Some of them are more researched than others, but it’s worth exploring the most common ones to note their possible effects. While some can come from a lab, others are naturally found in certain foods such as chili peppers, coffee, and guarana. Most brands combine these two groups and create the best metabolism booster pills and supplements to help you deal with unwanted weight gain and assist in reaching your goals.
Effects of Metabolism Boosters on Losing Weight
The best metabolism booster pills claim to have an effect on weight loss and fat-burning hormones in the body through a combination of its ingredients, such as caffeine, resveratrol, green tea extract, conjugated linoleic acid (CLA), and others. Some of them contain pure lab-grade compounds, another claim to be all-natural, while the majority feature some sort of a mixed formula that combines both.
The effects metabolism boosters have on losing weight happen due to thermogenesis, appetite suppression, a reduction of cravings, and overall improved performance during your workouts. This way, you’re burning more calories, using fat storage for fuel, and consequently, losing weight and optimizing your muscle gains. Supplements are not the only way to get that weight off and keep your metabolic rate high; eating a balanced diet high in protein-rich foods helps maintain blood sugar levels and satiate the appetite.

Instant Knockout
If you’re looking for a metabolic booster pill that very effectively suppresses appetite, Instant Knockout is the way to go. Being very high in glucomannan, that’s exactly what it does.
- Scientifically backed for suppressing appetite
- All-natural ingredients
- Certified vegan friendly
- Pricey
- Very high in caffeine
Created for combat sports athletes, Instant Knockout is a metabolism booster supplement with a strong appetite suppressing 2.0 Cut Above Formula, which helps you burn fat and lose unwanted stubborn fat in a very safe and trusted way while helping you maintain muscle mass. It contains glucomannan[3], an ingredient that is made from the root of the Japanese konjac tree. It suppresses the appetite by expanding in the stomach and thereby helping decrease hunger. This keeps you fuller for longer and helps you from reaching out for yet another unnecessary snack between your meals. Also, all the ingredients are natural and scientifically backed, so it’s no wonder that so many people trust this brand.
CrazyBulk Clenbutrol
Best legal, a metabolic boosting alternative to the infamous fat-burning clenbuterol. It stimulates thermogenesis and helps to burn calories by boosting metabolism while keeping your lean muscle for as long as possible.

CrazyBulk Clenbutrol also increases your oxygen flow, improving your cardiovascular performance and helping you reap the benefits of each and every workout you do. It’s important to note that even though it strongly emphasizes how much it affects your workouts, you do not have to be a professional athlete to use CrazyBulk Clenbutrol. It will be just as much work if you only go to the gym a few times a week. The effect comes from within, and the more your body fires up, the more calories (and fat cells) it will burn.
Best Metabolism-Boosting Ingredients
Caffeine
Probably one of the best metabolism boosters is caffeine. It’s well-researched[4] and the effect it has on promoting thermogenesis and actually boosting your metabolism has been proven. The existing studies all agree on a minimum daily dose of 270 milligrams of caffeine being the base limit for people to burn more calories than they would without it.
For reference, the majority of caffeine supplements have around 200 mg of caffeine, and one cup of coffee has between 80 and 100 mg of caffeine[5], depending on how the coffee was prepared and sourced.
L-Carnitine
Another popular metabolism booster is L-carnitine[6], an amino acid compound that plays a crucial role in energy production as it helps convert fat into energy. It’s produced by our bodies, but it can also be found in animal products, nuts, and legumes.
Most people get enough L-carnitine from their diet, but many often choose to take it in supplement form in order to stimulate their metabolic rate and help them burn fat as well as lose body weight.
Another health benefit is this amino acid helps to stabilize blood sugar levels which will help curb stubborn cravings that frequently lead to an unwanted increase in body weight.
Even though its exact effect on weight loss is questionable, it does help convert fat into energy and can therefore be a helpful additional tool for those trying to boost their metabolism. Still, it’s important to note that taking too much[7] L-carnitine in supplement form can have a potentially negative effect and yield some dangerous side effects, so taking precautions is always necessary.
Green Tea and its Catechins
Green tea and green tea extract have been on the list of the best metabolism boosters for years and the reason for it are catechins[8], very potent antioxidants[9] that reportedly have a great effect on our metabolic rate. Some studies[10] really do show its efficacy in burning fat and reducing cholesterol, so it’s no wonder that many metabolism boosters have green tea extract as one of their main ingredients.
Resveratrol
One of the most potent antioxidants in the world, resveratrol[11] is found in the skin of red grapes, mulberries, peanuts, and Japanese knotweed. It’s known for its anti-inflammatory and cancer-preventing properties. As a metabolism booster, resveratrol has proven to be efficient in studies done in rats[12], but unfortunately, there’s not enough evidence to support its use in humans yet[13]. Still, given their highly potent antioxidant properties, there’s not much harm in adding them to a metabolism-boosting supplement, so many of today’s brands have it in their ingredient list.
Capsaicin
The Chili pepper extract capsaicin may have a great impact on boosting our metabolism and promoting fat burn[14]. It seems that ingesting capsaicin can increase the number of calories you burn[15] by approximately 50 calories a day. That’s why this chemical is a very common ingredient in many metabolism booster supplements. Even in its raw, natural form when eating chili peppers, you’ll already feel your body temperature increasing and thermogenesis happening, so you can literally experience its metabolic boosting effects.
Conjugated Linoleic Acid (CLA)
A group of omega-6 fatty acids, conjugated linoleic acid, or CLA[16], is thought to be a metabolic booster, aiding in promoting weight loss and burning fat. Some studies[17] show its effect on weight loss, but the results may vary from person to person. It’s important to note though, that common side effects of taking these fatty acid supplements are gastrointestinal problems and fatigue. This may deter many from taking a metabolic booster with CLA in its list of ingredients.
Chromium Picolinate
This metabolic booster is a form of the mineral chromium, which is safe and can mostly be found in supplements. Its effect on weight loss and fat burning[18] has been studied for years as the results show a decrease in appetite and reduced cravings[19]. This consequently turns it into a great weight loss tool that, when combined with a stimulant like caffeine, can have real visible effects on helping you rid yourself of stubborn fat.
How To Choose Metabolism Boosters?
When it comes to choosing which metabolism booster is right for you, it depends on a myriad of factors such as your age, gender, level of activity, current weight and BMI, and whether or not you suffer from some physical or mental illnesses. The current metabolism boosters on the market differ in the ingredient list, advertised effects and side effects, and who they’re suitable for.
The Ingredient List
Some brands go the lab way and choose tested and clinically sourced ingredients, and others go all-natural, and the third group of brands chooses to combine the two. How you choose, your formula depends on your preferences and whether or not some of the ingredients are known to be harmful to you. If you’re already taking some medications, always consult with your doctor before adding a metabolism booster to your routine.
Backed by Science
While there are many different metabolic booster pills on the market, it’s important to see which brand’s formula is actually backed by science and clinical trials. Many of them claim to be the “best out there,” but without transparency, it’s hard to know what’s hidden in those pills. Always make sure to do your research before trying to add a dietary supplement to your regimen.
Advertised Effects
Most metabolism boosters exist for the sole purpose of boosting your metabolism and helping you lose weight while burning fat. Still, some brands claim they also help improve your athletic performance while you maintain lean muscle mass. If you’re training for a specific goal, these brands may be more beneficial to you.
Raving Testimonials
If you’re someone who loves reading positive reviews and uses it as a measure to trust a brand, then there’s no better way to choose a metabolism booster that’s right for you than by browsing through them—one by one.
Potential Side Effects
Some metabolism booster pills warn about the potential side effects that may be harmful, including gastrointestinal issues, fatigue, vomiting, headaches, and more. Always read the fine print and check to make sure you know the potential adverse side effects before you take them.
How To Increase Your Metabolism?
Metabolism booster pills are a great tool to have at your disposal, especially if nothing you’re currently doing isn’t moving the needle. They can be an amazing addition to your daily routine, which already consists of other natural ways to boost your metabolism. These include:
Drinking More Water
Studies show that increasing your water intake can help speed up your metabolism[20]. It stimulates thermogenesis[21] as the body has to burn calories to warm the fluid to body temperature. Drinking water also helps suppress your appetite and promotes the better overall function of your entire body.
Exercise
Increasing your daily activity level boosts your metabolism like nothing else will ever do. No matter what type of exercise you choose to do, it stimulates heat production in your entire body and helps you burn more calories. Still, studies show that the best type of exercise to increase your metabolism is HIIT (high-intensity interval training), as it promotes fat burn long after the workout has finished[22].
Eating More Protein
Protein is a macronutrient that is known to increase the thermic effect of food[23], also known as TEF, the most. It causes your body to heat up in order to properly digest it and therefore uses more energy to do so. This way, eating protein-rich foods boosts your metabolism the natural way and may also alleviate food cravings.
Keeping a Healthy Sleep Routine
Sleep is your recovery time, and the more you focus on optimizing it, the better your metabolic rate will be[24]. Lack of sleep has been linked to higher obesity rates and inflammation, insulin resistance, and diabetes, as well as depression and anxiety. Sleep also affects your hunger and satiety hormones, and if you’re not getting enough of it, you might feel hungry when you actually aren’t and full when you should be eating.
Drinking Coffee and Green Tea
Most metabolic booster pills contain caffeine and/or green tea extract, as these two compounds have an impressive effect on jumpstarting your metabolism and burning fat. They are also naturally present in coffee and green tea, so drinking them may help you get the same effect[25].
Eating Spicy Foods
Other well-known ingredient of many metabolic booster pills is capsaicin and chili pepper extract. Try adding it to your diet and let your body naturally reap its metabolic-boosting benefits. If you take a thermogenic fat burner with chili pepper extract, you won’t have to eat spicy foods to increase metabolism and promote fat loss.
Final Thought
Best metabolic boosters usually come in the form of pills, and while there seem to be new ones coming out almost on a weekly basis, it’s important to note that they are not magical. Whether or not they’ll work depends on the rest of your daily routine. Clean up your diet, stay hydrated, increase your daily activity level, and optimize your sleeping routine. With this healthy routine, make sure your metabolism booster pill has natural, trusted ingredients that are scientifically backed. This way, you’ll be on your very best way to a healthier, lighter, better you.
