Chronic Thermogenic Dietary Supplement Consumption: Effects on Body Composition, Anthropometrics, and Metabolism.

Our assessment

This study examined the effects of a multi-ingredient thermogenic supplement taken over time. Researchers studied 52 healthy, exercise-trained participants, half of whom were female, with an average age of 23.5 years. The study lasted for a set period and compared a group taking a thermogenic supplement plus whey protein to a group taking whey protein alone (PRO; n = 20) NIH ODS ↗. Because the total sample size is under 100, this is considered a small study, which means results should be viewed as preliminary NIH ODS ↗.

How it works

The key finding is that chronic consumption of a thermogenic supplement did not produce significant changes in body composition, resting energy expenditure, or metabolism compared to the protein-only group. For you, this means that while these supplements may provide a short-term energy boost, the data does not support their use for long-term weight loss or body fat reduction. The study measured changes in body fat percentage, weight, and metabolic rate, but the differences between groups were not meaningful NIH ODS ↗.

Safety profile

Data not available — no specific side effect reports from the FDA were provided for this supplement. The study itself did not report adverse events from the 52 participants, but the lack of FDA data means we cannot comment on broader safety issues or report counts of side effects FDA FAERS ↗.

Our recommendation

Based on this single study, there is no strong evidence to recommend chronic use of thermogenic supplements for improving body composition or metabolism. If you are considering such a product, focus on a balanced diet and regular exercise, which have far more data supporting their effectiveness NIH ODS ↗. Always consult a healthcare provider before starting any new supplement regimen, especially if you have underlying health conditions.
