Until recently, many doctors recommended the multivitamin only to women who were planning to get pregnant, or to those whose diets appeared to lack sufficient variation. Now many doctors recommend that taking a multivitamin is good insurance for all patients. Certain vitamins have been indicated in numerous beneficial health effects. For example, B vitamins may help control mood instability during menstrual periods, and vitamin D tends to be helpful to the many people who don’t get enough daily sun.

However, if one does not eat a healthy, balanced diet, like the one proposed in the US Food pyramid, a multivitamin provides a poor substitute. In other words, taking a multivitamin is not a license to skip your fruits, veggies and grains. Many doctors believe that a daily multivitamin should be part of a healthy diet, not a substitute for it.

Many multivitamins, especially those purchased in health food stores, significantly exceed the recommend daily amounts of certain vitamins. This can be unhealthy. Extra doses of vitamins do not confer extra benefits, and in fact may be harmful. This is particularly the case with vitamin A, and with iron. Pregnant mothers, who take too much vitamin A, especially from an animal source, risk birth defects in their children.


However, pregnant mothers who do not take enough folic acid, prior to conceiving, also risk birth defects in their children. Thus a balance needs to be maintained. The trouble with many health food store varieties of vitamins is that high doses of certain vitamins are present.

For a while it seemed that some vitamins, like vitamin C, might actually quickly end the common cold. This has been studied in great depth, and been found to be untrue. High doses of vitamin C tend not to stop the common cold. However, normal doses of vitamin C may help promote slightly greater immunity, and greater absorption of iron.

Because of the “high dose” mentality of many multivitamins, most doctors recommend more common and less expensive variants of the multivitamin that are readily obtainable at drug and grocery stores. Brands like Centrum, or even generic brands seem to provide just enough vitamins without over-dosing.

Along with multivitamin supplementation for adults, some also recommend children receive a child’s multivitamin. This may be a good idea especially for the picky eater. If you have a child who lives on peanut butter and jelly or grilled cheese sandwiches, many important vitamins may be lacking from the diet. While kids should be gently encouraged to try other foods, a multivitamin may help provide a little extra nutrition insurance. However, be sure that the multivitamin used is one specifically for children.

The multivitamin also contains some minerals, like calcium and iron. Often doctors recommend calcium supplementation separate from the multivitamin, since iron interferes with the absorption of calcium. If you take calcium separately, this should be done at a different time of the day, than when one takes the multivitamin. In this way one reaps more of the benefits of added calcium to the diet.

Food nowadays (fruits and vegetables) do not have the same nutritional content as it did 50-100 years ago, so even if you're eating your five to 10 servings of plant-based food there will be gaps, so you need to take at least a basic multivitamin.

Food is grown with synthetic fertilizers due to demand and not nutrition, and they put less stress on the plants which therefore have fewer nutrients, phytochemicals, vitamins, etc. Also the Recommended Daily Allowance is not equivalent to what is needed for optimum health.

The world we live in is now tremendously polluted and a good/great diet is needed to help your body stay strong and eliminate toxins, etc. Supplements are not magic pills -- they

supplement your diet. You still need to exercise!

Finally, doctors are not nutritionists or dietitians. A lot of them don't even eat healthy or exercise. How many of them you know are fit and look like Tony Horton (except maybe a few), yet people still go for nutrition advice from them.

I think that multivitamins are overrated. Many contain far more of the vitamins then are needed. A balanced diet, moderate exercise and proper rest are what is really required to live a healthy life. Even those things are no sure thing.

A diet that is inadequate or unbalanced won't be counteracted by taking a Multivitamin. Unhealthy lifestyles are the major cause of health problems. Vitamins and minerals won't fix that. Unless your doctor advises you to take vitamins you shouldn't waste your money.

When I went through SEAL Training BUD/S Class 57 in 1970 I never took vitamins. I just made sure I ate at least three good meals a day. My son did the same. We both made it through training and made it to the SEAL teams.

Some people take multivitamin as an insurance, and probably for many people a daily multivitamin is beneficial, but I think that eating plenty of fruits and vegetables daily is a better way of getting necessary vitamins and minerals.

To much of any one vitamin or mineral can create problems. For example, too much iron can create problems for liver, on the other hand, chromium, to much of it, can interfere with zinc absorption.
