Are some of the recipe’s ingredients redundant?
Although some ingredients may seem redundant they all have a purpose and cannot be eliminated from the recipe. For example, as many as three different supplements may be providing some calcium to the recipe but they are all needed to meet the total calcium needs of the pets. Moreover, there may be more than one source of salt in the recipe but they may be added to provide the right proportions of sodium, chloride, potassium, and iodine. Using a variety of supplements prevents excesses in other nutrients that would otherwise be added if only one supplement was used. For example, if a calcium and phosphorus containing supplement was used as the sole source of calcium it might lead to adding unnecessary and even harmful levels of phosphorus. Likewise, adding only one type of salt might lead to an excess of potassium to meet the sodium requirement.
