Effect of Whey Protein on Protein Synthesis and Cardiovascular Health

A recent review of the effects of whey protein supplements on metabolism (Graf et al. 2011) highlighted the positive effects that whey protein appears to have on both glucose metabolism and muscle protein synthesis. A number of previous studies have looked at how a range of milk and dairy products are associated with reduced risk of cardiovascular disease and some metabolic disorders. The researchers stated that “In particular, whey protein seems to induce these effects because of bioactive compounds such as lactoferrin, immunoglobulins, glutamine and lactalbumin. In addition, it is an excellent source of branch chained amino acids.”

The researchers looked at 25 recently published trials that were examining  the effects of whey protein supplementation on measures of cardiovascular health (lipid and glucose metabolism, blood pressure, and vascular function) and on the musculoskeletal system. The researchers found that “Whey protein appears to have a blood glucose and/or insulin lowering effect” and “protein may increase muscle protein synthesis”.

The review provides further support for the use of Whey Protein by bodybuilders as part of a balanced nutritional approach. It is particular promising to note that the as well as the apparent increased muscle protein synthesis, whey protein also has a number of beneficial effects on cardiovascular health and function.
