Although chromium appears to be normal on the following graph, it is very low in ratio to copper, its associated element, so when supplementing chromium, its level will generally not go up at first, but it will gradually lower copper instead, and in the example below, potassium, since they are high in ratio to chromium. Only after copper and potassium have been reduced to normal levels, chromium may at that point start to go up. However, sufficient amounts of chromium are rarely used, so in practice, copper and potassium will just come down closer to normal, while chromium levels stay the same... Full Text
