Frequently Asked Questions

Does CLA actually help you lose weight?

CLA reduces body fat rather than total weight. The meta-analysis showed ~0.05 kg/week of fat loss, which translates to about 1 kg of fat over 5 months beyond what diet alone achieves. This is modest but consistent. Don't expect dramatic weight loss — CLA is a long-term body composition supplement, not a rapid weight loss solution.

How long does CLA take to work?

Most studies show measurable body fat reduction after 6-12 weeks of consistent use at 3.2+ g/day. The Gaullier 12-month study showed continued benefits over a full year. CLA works gradually — commit to at least 3 months before evaluating results.

Are there safety concerns with CLA?

At standard doses (3.2-3.4 g/day), CLA is generally well tolerated. Some concerns exist: the t10,c12 isomer may worsen insulin sensitivity in some people, and some studies show increased CRP (an inflammatory marker). These effects are typically mild. Monitor blood sugar if diabetic.
