If you haven’t heard, the FDA (US Food and Drug Administration) has proposed a rather hefty set of new laws on vitamins, herbs and dietary supplements.
The dietary supplement community already has a set of guidelines called The Dietary Supplement Health and Information Act of 1994 (DSHEA). The new bill proposed by the FDA would change the categorization of supplements, vitamins and herbs so that many would be listed as harmful. Fresh fruits and vegetables and whole grains are the primary sources of vitamins, carotenoids, and phytochemicals, as well as dietary fiber and beneficial minerals.The Food and Drug Administration (FDA) does not require manufacturers to provide any scientific evidence that their dietary supplements are safe and effective (unlike drugs, which must be proven both safe and effective through clinical trials). However, getting too much vitamin A from food or supplements significantly increases the risk for birth defects.
Experts recommend that pregnant women get no more than 3,000 mcg of vitamin A each day.Infants and Children.
Deficiencies in pregnant and breast-feeding women may cause nervous system problems in their babies.The gene defect that causes vitamin B12 deficiencies is responsible for pernicious anemia, a serious disorder that causes rapid heart rate, shortness of breath, dizziness, weakness, and fatigue. With the exception of vitamin D, supplements are helpful only for certain people (for example, during pregnancy or for people with deficiencies or certain illnesses), and they may actually be harmful for other people.
Considering the supplement industry has a $25 billion per year sales figure, the NDI Safety Tests, as they are called, could potentially pull all dietary supplements off the market. However, in some cases, infants may not get enough of vitamins K and D.Human milk contains low levels of vitamin K, and the newborn's immature intestinal tract may not produce enough of the baby's own supply. Most babies are given an injection of this vitamin at birth.Infants who are breast-fed by malnourished women or who do not get enough sunlight exposure may be deficient in vitamin D.
In these cases, supplements of 200 - 300 IU are recommended.Formulas are required to contain enough vitamins and minerals.
After infancy, most American children receive all the vitamins they need from their diet, unless they are severely deprived.
However, research suggests that many healthy children ages 1 to 11, especially African-American and Hispanic children, are not getting enough vitamin D.Smokers. Most evidence suggests there is little or no benefit.New StandardThe Recommended Dietary Allowance (RDA) for vitamins is gradually being replaced by a new standard called the Dietary Reference Intake (DRI).

Smoking can also interfere with the metabolism of vitamin D, resulting in poor muscle function.Taking supplements of antioxidant vitamins, especially beta-carotene, is harmful to smokers.
A well-balanced diet should provide most of the vitamins people need to stay healthy and prevent disease. Strict vegetarians may benefit from taking vitamin B12 supplements.Unlike carbohydrates, fats, and proteins, vitamins are not sources of energy. Because the body stores fat-soluble vitamins, they can be dangerous when taken in large amounts.Water-soluble vitamins include vitamin C and the B vitamins. Excess amounts are removed in the urine.Guidelines for Adequate Intake of VitaminsThe Recommended Dietary Allowance (RDA) for vitamins, set by the Food and Nutrition Board of the National Academy of Sciences-National Research Council, has been used for years as a guide for determining the amount of vitamins needed to prevent deficiency diseases. Strict vegetarians need to take vitamin B12 supplements, unless they get enough of this vitamin from fortified cereals and other grain products. The RDA is an estimate of the average requirements of dietary components such as calories, vitamins, minerals, and proteins that are needed to prevent deficiency. They may also need to take vitamin D and riboflavin supplements, or a multivitamin, and watch their iron levels.
Different groups of people need different amounts of vitamins based on their gender and age.The RDA is gradually being replaced by a new standard called the Dietary Reference Intake (DRI). Vegans, who do not eat dairy, eggs, fish, or meat may be at risk for vitamin A deficiencies if they do not eat plenty of dark-colored fruits and vegetables.Vitamin deficiencies may be particularly harmful in vegetarian children. Mothers who do not get enough vitamin B12 may cause growth and nervous system problems in their newborns.Dieters. This is the amount of the vitamin needed to meet the nutritional requirements for 50% of the population.Adequate intake (AI). Almost a third of elderly people do not get enough of certain vitamins and important minerals. Food and Drug Administration (FDA) is a complex issue.Vitamin and other dietary supplement labels now include nutrient information and list all of the ingredients in the supplement, including the parts of plants from which the ingredients are taken. People who are obese, or who have osteoporosis, limited sun exposure, or poor nutrient absorption may need to increase their intake to as much as 2,000 IU per day.Seniors also may have low levels of important B vitamins.

Older adults with symptoms of dementia should be tested for a B12 deficiency.Seniors need to use caution when taking vitamin supplements.
Because metabolism slows with age, it takes the liver longer to remove vitamins from the body. For example, a dose of vitamin A that might be harmless in a younger adult could be toxic in an elderly patient.People Who Avoid Sunlight. Pharmacopeia (USP), an independent organization that sets quality standards for drugs, has also implemented standards for vitamins. People who avoid sunlight or who are housebound, and whose diet is low in foods that contain vitamin D should take supplements.
People with darker skin are at higher risk for vitamin D deficiencies than those with whiter skin.
The FDA may also withdraw products from the market if their labels are false or misleading.People Who Should Take Vitamin SupplementsDietary supplement use is on the rise. In particular, more Americans are taking vitamin D and calcium supplements than in the past.However, studies have found no difference in mortality rates between people who take vitamin supplements and those who don't take supplements. A temporary lack of nutrients is unlikely to cause a serious vitamin A deficiency.ToxicitiesVitamin A is very toxic when taken in high-doses (more than 25,000 IU a day) for long periods of time. Most people who eat a healthy diet do not need vitamins, but there are some exceptions.Pregnant and Breastfeeding Women. Most B vitamins are involved in the process of converting blood sugar into energy.Vitamin B1 is essential for converting carbohydrates from food into energy. The human body stores several years' worth of vitamin B12, so deficiency of this vitamin is extremely rare.
However, people who follow a strict vegetarian diet and do not eat eggs or dairy products may need to take vitamin B12 supplements.
