The Nature of Vitamins
Vitamins are organic (carbon) compounds needed for normal function, growth and maintenance.
Vitamins are cofactors, they don’t do anything by themselves.
They are not a source of calories.
Vitamin Requirements Daily Values (DV): standard nutrient intake values
developed by FDA– Disease prevention– Best met through a consumption of a wide
variety of foods
Dietary Supplements $6 Billion Market
They are classified as “Nutritional Supplements” They are not foods, and not drugs.*
Supplements are “Product intended to supplement the diet and contains vitamins, minerals, botanicals, amino acids, and their extracts.”
NOT consumed as a food replacement Loosely regulated, “not evaluated by FDA”
By definition a “drug” is used to “prevent, treat or cure” disease. These terms cannot be used with supplements.
Use of some supplements is backed by scientific data.
