The Calorie Burning Thermogenic Effect
The main goal of a thermogenic pre-workout is to create the process of thermogenesis in the body. Thermogenesis is a metabolic process where the body burns calories to produce heat. The increase of core body temperature leads to the burning of calories which is the primary goal when trying to burn fat.
The ingredients found in thermogenic pre-workouts increase the process of thermogenesis, leading to increased fat burning. They also boost the metabolism to break down food faster, which increases the body’s ability to convert fats into energy.
Should You Switch to a Thermogenic Pre-Workout?
Thermogenic pre-workouts are great because they do the same thing that a pre-workout is supposed to, while additionally burning extra fat. Anything looking to increase the intensity of their workouts while burning fat should try one.
If you are in a cutting or dieting phase then a thermogenic pre-workout is a great choice for you. If you struggle with weight gain then these products are not for you. If you are caffeine or stimulant sensitive, then they are also not a good idea.
General Advice for Purchasing a Thermogenic Pre-Workout
It’s important to remember that a thermogenic pre-workout is not a magic pill. If you are eating healthy and in a caloric deficit, they will aid the body’s ability to burn fat. However, you cannot eat a poor diet and expect them to work.
Don’t exceed the recommended serving size on the ingredient label. Stimulants can be dangerous if taken more than needed. Don’t take pre-workout products at nighttime unless they are stim-free as they will mess up your sleep schedule.
Key Thermogenic Pre-Workout Ingredients
Here is a list of the best ingredients to promote thermogenesis in the body while working out. Look out for these when buying a thermogenic pre-workout supplement!
MitoBurn
MitoBurn or L-Baiba is known as an exercise mimicking supplement that boosts the metabolism. It has proven to increase fatty acid oxidation, increase BHB levels, and improve insulin sensitivity. The recommended dose range is 250-500mg
Synephrine
Synephrine plays a role in sports performance, appetite control, energy, mental focus, and cognition. All aid in workout performance and fat loss. This ingredient exerts metabolic enhancement without acting as a central nervous system stimulant.
This means it will not increase blood pressure or negatively affect the heart. Defiant Shredded and Black Tulip both contain this ingredient. The recommended dose range is 30-60mg, meaning Defiant Shredded falls below this range while Black Tulip goes beyond.
Grains of Paradise
This aromatic spice helps heal wounds, provides antioxidants, has anti-inflammatory properties, and aids in weight loss. Clinical trials have shown that grains of paradise reduce white adipose fat tissue.
Grains of paradise are found in Darkside Onslaught and Alpha Lion products. The recommended dose range is 40-50mg, meaning that all of the pre-workouts listed fall in the correct doing range.
5-HTP
5-HTP has many benefits, such as increasing serotonin production in the brain. High serotonin levels affect mood, sleep, and weight loss. It also helps increase feelings of fullness, allowing the consumer to eat less.
Testosterone and growth hormone are released during sleep, so sleep is very important for anyone in the gym and is also when the muscles rebuild. 5-HTP should be dosed at around 100mg.
White willow bark
Willow bark acts similarly to aspirin as it is used to treat pain, which helps with muscle soreness and recovery after a challenging workout. It is found in Alpha Neon Darkshred. The recommended dosage is 120-240mg, meaning that Darkshred falls in the proper range.
InnoSlim
InnoSlim is used to manage weight, blood sugar levels, and energy levels. It helps fight metabolic imbalance, allowing the metabolism to break down foods faster. InnoSlim also improves insulin sensitivity, which aids in fat burning.
It is found in Defiant Shredded. The recommended dosage is 250mg, meaning that Defiant Shredded is underdosed.
Capsaicin
Capsaicin has been shown to increase energy metabolism and exercise endurance in studies, which allows you to work out longer and harder, breaking down more muscle fibers.
EGCG
Supplementation with the green tea extract, EGCG increases fat oxidation during exercise. It does so by inhibiting enzymes that reduce the degradation of catecholamines.
Adrenaline and noradrenaline are catecholamines that use fat for fuel during exercise, saving muscle glycogen during workouts and instead burning fat.
L-carnitine
When supplemented, l-carnitine has been shown to improve exercise performance, recovery, reduce muscle soreness, and increase oxygen supply to muscles, which allows the muscle to recover and grow faster.
L-carnitine is a very popular and well-researched supplement, as it is found in every thermogenic pre-workout listed above. It is not found in Alpha Lion Superhuman as it is stim-free. The dosage range varies from 1000-4000mg to be effective, and all pre-workouts fall in that range.
What to Look for When Buying a Thermogenic Pre-Workout
Fully disclosed ingredient label
If the nutrition label contains a proprietary blend, that is a red flag, which means they are not stating what exactly is in the formula. They can be underdosing ingredients or using cheap fillers to save on money.
Check that an ingredient label reads full disclosure, meaning that they label every ingredient found in the pre-workout.
Decide how much caffeine you want to consume
Nowadays, supplement companies constantly add more caffeine into their pre-workout supplements. Every new version has an added caffeine boost.
Caffeine is suitable for many people to consume. However, if you are caffeine sensitive, you may want to choose a pre-workout with lower caffeine content. The best way to find out is to start small. Start with a half dose of pre-workout and see how it affects you. Then assess your tolerance.
Make sure ingredients aren’t significantly underdosed
Decide how much of each ingredient the pre-workout should contain. Research and compare the amount of each ingredient to other pre-workouts.
Go with a brand you trust
Reading ratings and reviews are a great way to see if customers are happy or have issues with the company. It is a good sign if they have a website with a phone number and email listed.
It is most likely a good product to purchase if their pre-workout supplement is available at multiple supplement retailers.
FAQs about Thermogenic Pre-Workout Supplements
This answer is different for everyone, depending primarily on how much of a calorie deficit you are in. By eating fewer calories than your body burns, you will be losing fat. If you add a thermogenic pre-workout, your body will burn even more fat.
Thermogenic pre-workouts will help you in your fat loss journey, but they will not work alone. You also have to eat in a deficit and consider adding in cardio.
If you are a beginner in the gym, pre-workouts probably aren’t the best to be using. Many people create a caffeine addiction by using pre-workout products. They get to the point where they have to take a higher dosage as their body becomes used to it.
Caffeine in high amounts can be dangerous. Pre-workouts contain high amounts of caffeine when double-dosing is dangerous. Pre-workout supplements are for advanced lifters who want to add intensity into their training.
Even advanced lifters should not abuse pre-workouts as they can build a tolerance. Caffeine breaks should be taken every once in a while, so this does not happen.
As with any exercise routine or nutritional supplement, it’s a good idea to check with a licensed medical professional before starting anything new.
With that said, a thermogenic pre workout is generally safe as long as you take the recommended dose and follow the instructions label. Staying hydrated and not combining them with any other medications or additional caffeine is vital for safety.
If you are sensitive to any of the ingredients found in a supplement, you should find a different pre-workout. Watch out for products with artificial sweeteners, proprietary blends, or ones that haven’t been third-party tested. Some contain strong stimulants like DMHA or alpha yohimbine, which may cause unwanted side effects.
The best way to determine if a product is safe is to see how it affects your body. If it is causing issues, then you should either find a new product or not use pre-workout.
