According to a study by a team of researchers from Barcelona University, the effect of Tonalin CLA in a skimmed milk product has shown a significant reduction of body fat mass (BFM) in overweight subjects.

Sixty overweight (BMI £ 30), but otherwise healthy men and women were randomized to a daily intake of 500 ml skimmed milk fortified with 3g Tonalin CLA, or a placebo milk, over a 12 week period.

The results showed a three per cent reduction of BFM in the overweight group taking the milk fortified with Tonalin. CLA supplementation was not associated with any adverse effects or clinical changes.
