Do thermogenic fat burners increase heart rate?
Some thermogenic fat burners may slightly increase heart rate because they often contain stimulant ingredients such as caffeine, green tea extract, or capsicum. These compounds work by boosting metabolism and energy expenditure, which can also stimulate the cardiovascular system.
For most healthy adults, this effect is mild and temporary when products are taken as directed. However:
- People sensitive to caffeine or stimulants may notice stronger effects
- Those with heart conditions or high blood pressure should consult a healthcare professional before use
Always follow the recommended dosage and check whether a stimulant-free (non-stim) fat burner may be a better option for your needs.
