Among the most popular minerals used to fortify foods and beverages are calcium, magnesium, potassium and phosphorus. Alone, each mineral fulfills unique nutritional requirements but, when used together, the effectiveness of certain minerals can be multiplied. For example, research shows that calcium needs phosphorus to maximize its bone-strengthening benefits.
Because soy beverages contain only one third of the calcium in cow's milk, many formulators are rushing to add this mineral to soy drinks. Calcium phosphates also enhance the nutritional value of meal replacement drinks, beverage mixes, energy bars, supplements and vitamins. New opportunities for calcium fortification also extend to soft drinks, energy drinks and bottled water.
