Water Soluble Vitamins

Water-soluble vitamins include the B-group vitamins and vitamin C. Their deficiency is treated by administration of the vitamin. B group vitamins:
 * A common feature of group B vitamins (except vitamin B12 ) is their occurrence in yeast, but yeast is not their major source for men if the yeast is included in the diet only as a means of rising bread - a small quantity of yeast does not contain nutritionally significant amount of B vitamins.
 * Their metabolic effects are inter-linked.
 * Deficiency of only one of them occurs rarely.
 * They are produced by the intestinal micro flora but the amount produced is generally only a fraction of the daily recommended intake.
 * Some are more frequently called by their name, others by number. Some numbers are missing, because it has been found that some substances, originally considered as vitamins, are NOT essential for humans, therefore they are not vitamins or are a mixture of substances.
