In part 42 of our A-Z series of nutritional supplements, having covered vitamins in parts 39-41, we finish off reviewing V by looking at valine, an essential amino acid (EAA) classified as a branched chain amino acid (BCAA), and vanadium, a trace element marketed as an aid to muscle growth in weight training. We then turn our attention to W, with the first W to be reviewed being `water (oxygenated)`. Oxygenated water products are marketed to athletes with a claim that, dependent on the product, they contain 3-30 times the oxygen content of normal tap water, and thereby could potentially be of benefit to health and performance.
