Can thermogenic supplements make you feel hot?

What are thermogenic supplements?

Overview of thermogenic supplements

Thermogenic supplements are dietary supplements that are commonly used for weight loss and fat burning purposes. These supplements are designed to increase the body’s heat production, known as thermogenesis, which in turn can potentially enhance metabolism and promote weight loss. They often contain a combination of ingredients that have been shown to have thermogenic properties, such as caffeine, green tea extract, capsaicin, yohimbine, and synephrine.

Mechanism of action

The mechanism of action of thermogenic supplements involves stimulating the body’s metabolism and increasing its heat production. This is typically achieved through various pathways, depending on the specific ingredients in the supplement. For example, caffeine acts as a central nervous system stimulant, increasing energy expenditure and promoting lipolysis, the breakdown of stored fat for energy. Green tea extract contains compounds called catechins, which have been found to accelerate fat oxidation and boost thermogenesis. Capsaicin, the active component in chili peppers, can enhance metabolism and increase energy expenditure. Yohimbine and synephrine are known to stimulate the release of adrenaline, which can further boost metabolic rate and fat burning. These ingredients work together to create a synergistic effect, helping to maximize thermogenesis and promote weight loss.

Can thermogenic supplements increase body temperature?

Effects on body temperature

Yes, thermogenic supplements can increase body temperature, although the degree to which this occurs may vary among individuals. The increased heat production caused by the thermogenic ingredients in these supplements can lead to a rise in body temperature, contributing to the “hot” sensation that some people may experience. This heat generation is a result of the increased metabolic rate and energy expenditure stimulated by the thermogenic ingredients. However, it is important to note that the effects on body temperature may not be significant or noticeable for everyone.

Thermogenesis and metabolism

Thermogenesis is a natural process that occurs in the body to produce heat. It is an essential component of metabolism, which refers to all the chemical reactions that take place within the body to sustain life. When thermogenesis is increased due to the consumption of thermogenic supplements, it can potentially contribute to a higher metabolic rate. A higher metabolic rate means that the body is burning more calories and utilizing stored fat for energy, which can ultimately aid in weight loss. The increase in body temperature associated with thermogenesis is a result of the increased energy expenditure and heat generation within the body.

Common ingredients found in thermogenic supplements


Caffeine is one of the most common ingredients found in thermogenic supplements due to its stimulating effects on the central nervous system. It acts as an adenosine receptor antagonist, blocking the activity of adenosine, a neurotransmitter that promotes relaxation and drowsiness. By inhibiting adenosine, caffeine increases alertness, improves focus, and boosts energy levels. In the context of thermogenesis, caffeine can also increase metabolic rate and fat oxidation.

Green tea extract

Green tea extract is another popular ingredient in thermogenic supplements. It contains a high concentration of catechins, which are a type of flavonoid with antioxidant properties. The catechins in green tea extract, particularly epigallocatechin gallate (EGCG), have been shown to enhance thermogenesis and increase fat oxidation. In addition, green tea extract can also improve insulin sensitivity and reduce the absorption of dietary fat, potentially contributing to weight loss.


Capsaicin is the compound responsible for the spicy sensation of chili peppers. It has thermogenic properties and can lead to an increase in body heat production. Capsaicin stimulates the sympathetic nervous system, resulting in the release of catecholamines such as adrenaline. This hormonal response can enhance thermogenesis and increase energy expenditure, ultimately aiding in weight loss and fat burning.


Yohimbine is derived from the bark of the Yohimbe tree and has been used for its potential thermogenic and fat-burning properties. It acts as an alpha-2 adrenergic receptor antagonist, which can increase the release of noradrenaline and adrenaline. In turn, this can boost thermogenesis, increase metabolic rate, and promote fat oxidation. Yohimbine is often used in conjunction with other thermogenic ingredients to enhance its effects.


Synephrine, also known as bitter orange extract, is a natural compound that has been used for its thermogenic properties. Like yohimbine, synephrine acts as an alpha-2 adrenergic receptor antagonist, leading to increased release of noradrenaline and adrenaline. This can stimulate thermogenesis, enhance metabolic rate, and promote fat burning. Synephrine is commonly used as a safer alternative to ephedrine, a stimulant that has since been banned due to safety concerns.

Potential side effects of thermogenic supplements

Increased heart rate and blood pressure

One potential side effect of thermogenic supplements is an increase in heart rate and blood pressure. The stimulant effects of ingredients like caffeine, yohimbine, and synephrine can cause these cardiovascular responses. While the effects may be mild for some individuals, those with underlying heart conditions, high blood pressure, or sensitivity to stimulants should exercise caution when using thermogenic supplements. It is important to monitor these vital signs and consult with a healthcare professional if any concerning symptoms arise.

Jitters and sleep disturbances

Thermogenic supplements that contain stimulants like caffeine can also cause jitters and sleep disturbances. The energizing effects of these ingredients may lead to feelings of restlessness, nervousness, or anxiety, especially when consumed in higher doses or close to bedtime. To avoid such side effects, it is advisable to regulate caffeine intake and consider lower-stimulant alternatives if sleep disturbances occur.

Gastrointestinal issues

Some individuals may experience gastrointestinal issues when taking thermogenic supplements, particularly those containing capsaicin or yohimbine. These ingredients can cause stomach discomfort, nausea, or indigestion. It is recommended to start with a lower dosage and gradually increase to assess tolerance and minimize digestive discomfort. Additionally, taking thermogenic supplements with food may help alleviate potential gastrointestinal side effects.

Dependency and withdrawal

As with any supplement or substance that affects the central nervous system, there is a potential risk of dependency and withdrawal when using thermogenic supplements. Regular and prolonged use of thermogenics can lead to the body becoming accustomed to the stimulant effects, resulting in a reduced response over time. This can create a dependency on the supplement to maintain energy levels or experience the desired effects. Abrupt cessation or a significant reduction in dosage can trigger withdrawal symptoms, such as fatigue, irritability, and headaches. To avoid dependency and withdrawal, it is advisable to cycle or gradually reduce usage rather than abruptly stopping thermogenic supplement use.

Effects of thermogenic supplements on weight loss

Appetite suppression

One of the potential benefits of thermogenic supplements is their ability to suppress appetite. The stimulatory effects of ingredients like caffeine and synephrine can help reduce feelings of hunger and increase feelings of fullness, thereby potentially aiding weight loss efforts by promoting calorie restriction. However, it is important to note that long-term appetite suppression may not be sustainable and may have potential negative effects on overall health and nutritional needs.

Enhanced fat oxidation

Thermogenic supplements can also enhance fat oxidation, which is the process of breaking down stored fat for energy. By increasing metabolic rate and thermogenesis, thermogenic ingredients like green tea extract, capsaicin, and yohimbine can promote the use of stored fat as fuel, ultimately contributing to weight loss. However, it is essential to maintain a balanced diet and regular exercise routine to optimize fat oxidation and achieve long-term weight loss goals.

Metabolic rate increase

By stimulating thermogenesis and energy expenditure, thermogenic supplements can increase metabolic rate. A higher metabolic rate means that the body is burning more calories even at rest, which can aid in weight loss efforts. However, it is important to remember that thermogenic supplements are not a magic solution and should be combined with a healthy diet and regular exercise for optimal results. Furthermore, individual variations in metabolic rate can influence the extent of any metabolic increase experienced with thermogenic supplements.
