To have a resource of all vitamins, minerals, proteins, fats, carbohydrates to the body, a person would eat a balanced diet. This is like Perfect Health Serum in your question.
But when there is deficiency of Vitamin C, that person will eat Vitamin C rich diet like oranges, lemons or even take Vitamin C supplements along with balanced diet. This is like your other organ specific health serums.
You can please read about Perfect Health Serum and other health serums to know more how each Cosmic serum helps and decide the best combinations.
You can charge two different waters with different combinations of energies/Cosmic Serums each related to different healing requirements.
