MineralsMinerals In addition to vitamins your body also

needs 15 minerals that help regulate cell function and provide structure for cells. Major minerals, in terms of amount present, include calcium, phosphorus, and magnesium. In addition, your body needs smaller amounts of chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, zinc, chloride, potassium and sodium.

Amounts needed for most of these minerals is quite small and excessive amounts can be toxic to your body.

WaterWater Water is your body's most important

nutrient, is involved in every bodily function, and makes up 70- 75% of your total body weight. Water helps you to maintain body temperature, metabolize body fat, aids in digestion, lubricates and cushions organs, transports nutrients, and flushes toxins from your body.

Everyone should drink at least 64 ounces per day, and if you exercise or are overweight, even more. Your blood is approximately 90% water and is responsible for transporting nutrients and energy to muscles and for taking waste from tissues.
