What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

L-carnitine, green tea, and green coffee bean extracts are studied for their roles in fatty acid metabolism and thermogenesis, though evidence for significant weight loss is generally moderate to limited. Niacin supports cellular energy production, while Capsimax may influence metabolic rate. These ingredients are widely recognized as safe for most healthy adults.
