DFA: Conjugated Linoleic Acid (CLA) Supplementation and Intermediate Health Outcomes (2011)
What is the effect of conjugated linoleic acid (CLA) on body composition and weight loss in healthy adults?
Fair evidence indicates that three to six months of conjugated linoleic acid (CLA) supplementation results in a decrease in fat mass and an increase in fat-free mass in healthy adults; however, fair evidence indicates that CLA does not affect body weight.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
