A novel form of vitamin B3 found in milk in small quantities produces remarkable health benefits in mice when high doses are administered, according to a new study conducted by researchers at Weill Cornell Medical College and the Polytechnic School in Lausanne, Switzerland. The findings, recently reported in the June 2012 issue of the journal, Cell Metabolism, reveal that high doses of the vitamin precursor, nicotinamide riboside (NR) — a cousin of niacin — prevent obesity in mice that are fed a fatty diet, and also increase muscle performance, improve energy expenditure and prevent diabetes development, all without side effects.
