EFSA Rejects Weight Loss Claims For Whey Protein Prolibra

The European Food Safety Authority (EFSA) has rejected claims by Glanbia Nutritionals Inc. that consumption of Prolibra, its hydrolyzed whey protein isolate containing peptides and milk minerals, “helps to reduce body fat while preserving lean muscle.” The EFSA said the company did not describe the whey peptide's full manufacturing process and provided no information on the enzyme used for the specific conditions applied. The authority said that Prolibra was therefore “not sufficiently characterized in relation to the claimed effect”.
