Your first response may be, "no - I don't need to take vitamins I eat a healthy diet" but statistically chances are you don't. The USDA has reported only 10 percent of Americans actually eat a good diet. One cited example, only 17 percent of people consume the recommended number of servings of fruit per day.
For women it's especially an issue, the USDA’s Continuing Survey of Food Intakes
by Individuals (CSFII) revealed adult females failed to meet the recommended daily intake (RDA) for five nutrients: calcium, vitamin E, vitamin B6, magnesium and zinc.
I've been monitoring my diet, which has led me to discover how difficult it is to try to increase B6, as an example, through food sources.
