The recommended daily allowance of potassium for a teenager is 2000 milligrams daily from food. A typical American's daily intake of potassium is about 4000 milligrams. Unless you are having excessive losses of potassium from your body such as diarrhea or vomiting, you should not have a problem with getting enough potassium from your diet. Also, as long as your kidneys are working properly, you need not be concerned about getting in too much potassium from foods. The kidneys will get rid of any excess potassium consumed.

Potassium is very important in cellular biochemical reactions and energy metabolism. Potassium also functions in carbohydrate metabolism; it is active in glycogen and glucose metabolism, converting glucose to glycogen that can be stored in the liver for future energy.

Calcium is needed for your bones. About 1300 mg. calcium from your diet or equivalent to 4 servings milk (8 oz. glass each). You will also need vitamin D which is obtained from about 10-15 minutes in sunshine or from foods with D added. Cheese, yogurt, milk are good sources for calcium.
You should know that soft drinks will leach calcium from your bones. Be sure and drink healthy drinks and eat a healthy diet, drink plenty of water.
