This study found that those taking all three supplements experienced more gains in bench press and leg press strength, along with lean tissue gains, than the other groups combined. The groups taking creatine gained more lean mass than those who took only whey protein. Previous research showed that CLA produced greater gains in bench press strength in men but no effect on leg press strength and also no effect in women. While the precise mechanism of how CLA can influence muscle gains isn’t clearly established, one plausible hypothesis is that it reduces the inflammatory cytokines that produce muscle catabolism, such as tissue necrosis factor-A, a signaling agent in the loss of muscle. It’s a primary suspect in the loss of muscle with age, as its levels increase in the elderly. CLA didn’t produce any changes in fat mass in this study, although previous studies showed that it’s more effective in those who have more initial body fat. It doesn’t do much for people who are already lean.
