Vitamin Mistakes Most People Make

For simplicity, use the B-vitamins as your reference point. Look for a product that supplies about 40 milligrams (mg) each of thiamin, ­riboflavin, niacin and vitamin B-6 (pyridoxine), and 200 ­micrograms (mcg) of vitamin B-12. These levels are safe and therapeutic, improving energy and mental clarity. When a product contains the above levels of these nutrients, it usually will have optimal levels of other nutrients as well.
