Is there really a difference in the quality of name brand vitamins and store brand or generic?
In most cases there is no difference between name bread vitamins/minerals or generic except price. You can compare the Supplement Facts to ensure they contain the amount of nutrients you want or need. As required by FDA, dietary supplements must show on their labels or packaging the percent of the Daily Value for vitamins and minerals they contain. The Percent Daily Value (DV) is the amount of nutrients in one tablet or capsule. The Daily Reference Value for nutrients for adults are: 1000 milligram (mg) calcium, 2 mg copper, 0.4 mg (400 microgram – mcg) folic acid, 18 mg iron, 400 mg magnesium, 20 mg niacin, 10 mg pathothenic acid, 1000 mg phosphorus, 1.7 mg riboflavin, 1.5 mg thiamine, 5,000 international units (IU), 6 mcg Vitamin B 12, 2 mg Vitamin B-6, 60 mg Vitamin C, 400 IU Vitamin D, 30 IU Vitamin E, and 15 mg zinc. Keep in mind, you can get many of these vitamins and minerals in the foods that you eat. Boron, nickel, silicon, tin, vanadium, lutein and lycopene do not have an established Daily Value.
