As saying the results imply that anyone interested in reducing abdominal fat should begin taking a safflower oil supplement. In the study, the effects of taking conjugated linoleic acid (CLA, an agent promoted for weight reduction) and safflower oil over two 16-week periods were compared.

If you're looking for an effective addition to your health regimen for burning fat, then look no further! Swanson Tonalin CLA (conjugated linoleic acid) is a patented fatty acid supplement produced from a safflower oil blend that works to help burn body fat while promoting lean muscle development.

CLA can also cause other less serious side effects like diarrhea, stomach pain, nausea and flatulence (42). Bottom Line: The CLA found in most supplements is different from the CLA found naturally in foods. Several studies have shown disturbing side effects from CLA, such as increased liver fat.
