Riboflavin is unique among the water-soluble vitamins in that milk and dairy products make the greatest contribution to its intake in Western diets. Meat and fish are also good sources of riboflavin, and certain fruit and vegetables, especially dark-green vegetables, contain reasonably high concentrations. Biochemical signs of depletion arise within ...

Reactive nitrogen oxide species (RNOS) have been implicated as effector molecules in inflammatory diseases. There is emerging evidence that gamma-tocopherol (gammaT), the major form of vitamin E in the North American diet, may play an important role in these diseases. GammaT scavenges RNOS such as peroxynitrite by forming a stable ...
