People with poor eating habits would do better if they improved their diet rather than investing in nutritional supplements. There are, of course, times when nutritional supplements are strongly recommended. For example, women who are pregnant or wish to become pregnant in the near future should add folate to their diet because adequate folate intake in the first 3 months of pregnancy helps prevent some birth defects. It is possible to get enough folate by eating a diet rich in fruits and vegetables, but such a diet can be difficult for pregnant women to maintain. Taking a supplement can insure that a pregnant woman reliably gets enough folate.
Nutrition is a complicated topic.
If you see your doctor to discuss your interest in eating well, together you can decide whether a specific nutritional supplement is a worthwhile investment. Always consult your own doctor about any opinions or recommendations with respect to your symptoms or medical condition. Beth Israel Deaconess Medical Center .
