Evidence-Based Benefits

  • Fat loss — Whigham et al. (2007, meta-analysis, 18 RCTs, n=795) found CLA at 3.2 g/day reduced fat mass by 0.05 kg/week vs placebo
  • Body composition — Blankson et al. (2000, n=60) showed CLA 3.4-6.8 g/day significantly reduced body fat mass without affecting lean mass over 12 weeks
  • Long-term effects — Gaullier et al. (2005, n=180) found CLA 3.4 g/day reduced body fat by 8.7% vs placebo over 12 months
  • Mechanism — t10,c12-CLA inhibits lipoprotein lipase and stearoyl-CoA desaturase, reducing fat storage in adipocytes

What the Research Says

CLA has one of the larger evidence bases among weight management supplements, with 18+ RCTs and a comprehensive meta-analysis showing consistent but modest fat loss. The effect is small (~0.05 kg/week of fat loss) but statistically significant and maintained over long periods. CLA does not typically reduce scale weight dramatically because it may preserve lean mass. Safety concerns about insulin resistance and inflammatory markers warrant monitoring in at-risk populations.
