Table 1 Comparison between Capsiate supplementation and placebo groups on the body compositionand performance. Data are presented as mean +/- SD

From: Chronic capsiate supplementation increases fat-free mass and upper body strength but not the inflammatory response to resistance exercise in young untrained men: a randomized, placebo-controlled and double-blind study
