Bottom line

Read Off Label grades CLA (conjugated linoleic acid) as C (5.1/10) based on weak-moderate evidence, low benefit magnitude, and a low-med-risk safety profile.

Early enthusiasm has faded.

Studied, labeled, or reported-use context: 3-6 g/day — OTC; not individualized guidance.

What the evidence says

Early enthusiasm has faded. Modest fat loss (~0.5-1 kg over 12+ weeks) at best. Some studies show worsened insulin sensitivity and increased oxidative stress. The average fat-loss effect is modest and no longevity benefit has been established.

Mechanism

Isomers of linoleic acid; proposed modulation of PPAR-γ, SCD-1, lipoprotein lipase; inhibition of adipocyte lipogenesis

Studied, labeled, or reported dose & route

3-6 g/day

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
