Compound In Milk Helps Boost Metabolism, Increase Endurance

A multinational team of researchers has determined that an ingredient in milk – nicotinamide riboside – boosts the activity of the gene SIRT1, which benefits metabolism and longevity. In a mouse study, animals that took nicotinamide riboside in fairly high doses while eating a high-fat diet burned more fat and were protected from obesity. Thanks to a boost in endurance, they also become better runners. The researchers suggested that the milk substance seems to offer the same benefits as resveratrol, and could help in achieving slimmer waistlines and perhaps longer lives.
