Still getting into the right groove in 2023? Don’t worry; January was just a warm-up.

If you’re trying to tackle your weight goals while you train, thermogenics might be the answer you have been missing.

Never heard of them? Let us tell you why thermogenics can be the hero of your weight-loss stack.

What are thermogenics?

Thermo is the keyword.

Thermogenics are designed to produce heat. Your body generates more heat when burning calories, so supplements that boost metabolism are considered thermogenics. Thermogenics are commonly referred to as ‘fat burners’ and can be effective at boosting metabolism, increasing fat oxidation and supporting appetite reduction (Julson, E. 2018).

If you’re trying to burn additional fat while you’re training, thermogenics can give you a helping hand. Going for an early morning run? Pop a scoop of your favourite thermogenic (or one of our best-sellers below) and start tackling your weight goals every time you exercise.

What ingredients do they contain?

Thermogenic formulas contain a variety of ingredients that are designed to boost energy, speed up metabolism, and assist in weight management. These formulas are best taken as a pre-workout and commonly include specific thermogenic ingredients to support thermogenesis.


Caffeine is usually the star of the show when it comes to its role in supplements, but more specifically pre-workouts and thermogenics. It’s not surprising when you see how much it can do. Caffeine is generally the core of any effective pre-workout and is praised for its stimulating functions and ability to boost energy, mood and cognitive function. It is also a cornerstone in most thermogenic formulas. Why? Because it can stimulate the nervous system, break down fat, increase your metabolic rate and support a reduction in appetite (Gunnars, K. 2018).

Green Tea

Green tea is considered one of the world’s healthiest beverages. It is loaded with antioxidants and plant compounds that may increase fat burning, support fat breakdown and boost metabolic rate. It can also help you consume fewer calories and may be effective when attacking visceral fat (Gunnars, K. 2018).


L-Carnitine is an amino acid derivative that can support weight loss and brain function. It plays a critical role in transporting fatty acids into your cells’ mitochondria, where they are oxidised into usable energy (Mawer, R. 2018).

Bitter Orange Extract

Bitter Orange Extract is an effective ingredient in most thermogenic formulas due to its effects on metabolic processes. This includes supporting an increase in basal metabolic rate, increasing lipolysis, and may support mild appetite suppression (Stohs, S et al. 2012).


Capsaicin is a molecule found within peppers, and it is commonly used in therapeutic gels, ointments and patches designed for pain relief. Capsaicin can support weight loss by increasing your metabolism, improving the rate that you use energy and burning fat stores. It may also help to lower your appetite between meals (Juber, M. 2022).

5 Reasons why you should take a Thermogenic!

Supports your weight goals

Thermogenics can support your weight goals by helping to increase your resting metabolic rate, which can facilitate weight loss (Campbell, B. 2016).

Can help boost metabolism

Thermogenic supplements can help boost your metabolism, which means you can burn more calories during activity and rest (Harvard Medical School. 2021).

Enhances mental performance

Thermogenics can boost your mental performance. Ingredients like caffeine can boost your performance by increasing adrenaline levels, stimulating your fat cells to release fatty acids, and boosting metabolism (Julson, E. 2018).

Boosts energy levels

Thermogenic formulas can enhance your energy levels by elevating your blood pressure and increasing your overall energy expenditure. Increasing your energy expenditure is pivotal if you are trying to lose weight (Taylor, M. 2021).

Can enhance focus

Caffeine, L-Tyrosine, L-Taurine, Acetyl L-Carnitine, and Alpha GPC are all common ingredients in thermogenics that can effectively boost your focus and optimise your performance. These ingredients, among others, can increase focus, cognitive function and alertness (English, N. 2022).
