Is your dietary intake meeting your metabolic needs?
The US Dietary guidelines recommend five servings of vegetables and fruits to provide essential micronutrients to support healthy living and optimal function.
A balanced meal plan doesn?t always equal necessary nutrient intake. We push our bodies to the limit, and beyond, while often overlooking undernourishment. In order to meet our expectations, nutritional supplementation is necessary to decrease injury and disease.
Most diets lack sufficient nutrient intake.
Research shows that micronutrient supplementation decreases injury and disease which lowers healthcare costs.
Dietary intake of antioxidants decreases inflammation and can improve quality of life.
Specific dietary vitamin and mineral deficiencies can increase an individuals risk of certain chronic conditions.
A particular group of B vitamins - vitamins B2, B6, B12, and folic acid - are involved in helping the body metabolize homocysteine, which, like cholesterol in higher levels, increases cardiovascular risk factors. In a study of 178 women (ages 60-70 years), one-third were deficient in vitamins B1, B6, and B12, which, in turn, was associated with increased levels of homocysteine.
Similar findings were found in a study of men, in which supplementation with B vitamins (B6, B12, and folic acid) helped maintain healthy homocysteine levels. Although the research has not always been consistent, some studies show a decrease in cardiovascular risk factors in individuals who take a daily multiple-vitamin product., 
Intake of antioxidant supplements appears to decrease cognitive health risk factors. Antioxidants commonly found in a multiple vitamin-mineral supplement include vitamin A/beta carotene, vitamin C, vitamin E, zinc, and selenium. Higher dietary vitamin E intakes have been associated with improved performance on mental functioning tests, while low levels of selenium have been seen in patients with cognitive deficiencies.
Deficiencies of several B vitamins, especially folic acid, are also associated with decline in cognitive function.
Intake of vitamins and minerals might also decrease the risk for certain age-related eye deficiencies.[9-10]
A new study conducted by researchers at a number of leading research institutions discovered that the use of nutritional supplements in patients 65 or older decreases the probability of a 30-day hospital readmission, thereby reducing healthcare costs. With one in five Medicare patients being readmitted to a hospital annually at a cost of $17.5 billion dollars, such a finding has dramatic implications for the positive benefits of nutritional supplementation. 
Vitamin D deficiency is common in the general population, but deficiencies can increase with age due to medication intake, absorption issues, and the fact that the elderly are not as likely to spend as much time in the sun, which increases vitamin D levels. A vitamin D deficiency can have adverse effects on bone and muscle strength, immune function, and a greater tendency to fall.12
The suboptimal intake of several important vitamins is common in the general population, particularly among older Americans. In a study of 4,381 adults ages 51 or older, less than 50 percent received adequate amounts of vitamin E, folic acid, or magnesium from diet alone.
