Women’s health and dietary supplements— published: 10-01-2012
About half of all military personnel use some dietary supplements, and military women most commonly use weight-loss supplements. But is there a place for dietary supplements in enhancing women’s health? Dietary supplements, by definition, are intended to “supplement the diet” and can contain a dietary ingredient such as a vitamin, mineral, herb or other botanical, amino acid, or combinations of these and/or other substances or constituents intended to be consumed by mouth.
Active women may require more nutrients, but vitamin and mineral needs normally can be met by eating a variety of nutrient-rich foods. The Dietary Guidelines for Americans focus largely on the recommendation that nutrient-dense foods and beverages—such as fruits, vegetables, whole grains, low-fat dairy products, lean meats and poultry, eggs, nuts and seeds—can provide all the nutrients needed by most everyone. These recommendations are based on research that shows a varied, healthy diet lowers the risk of most diseases.
Some dietary supplements have been found to be beneficial for women’s health, such as folic acid, iron, and calcium. Folic acid, a B vitamin involved in the production of new cells in the body, has been shown to help prevent birth defects. Women who are thinking of becoming pregnant or are pregnant should take a supplement that includes 400 micrograms of folic acid per day. Fortified foods such as green, leafy vegetables, enriched whole grain breads, flour, pasta, rice, and most ready-to-eat cereals also contain folic acid. Adolescent girls, women of childbearing age, and especially pregnant women also need more iron, which is a mineral involved in the transport of oxygen in the body. Women in these groups should choose iron-rich foods, particularly red meat, fish, and poultry, as well as iron-fortified foods. When iron levels are low, symptoms may include feeling extra tired and weak, along with a decrease in immune function. A healthcare provider or dietitian can determine the need for supplementation if diet alone cannot maintain iron levels or for those who have iron-deficiency anemia. Calcium is an important mineral that helps maintain strong bones, healthy teeth, and proper functioning of the heart, muscles, and nerves. All women should strive to get their calcium from foods such as low-fat milk, yogurt, cheese, dark-green, leafy vegetables, and foods such as orange juice and soy milk that have been calcium-fortified. Those who may need more should discuss calcium supplement options with a dietitian, since there are many forms available and it is important to determine how much and which kind is suitable for your particular needs.
Some dietary supplement products marketed for weight loss are targeted toward women. Do they work? According to the Food and Drug Administration (FDA), some weight-loss supplements contain hidden prescription drug ingredients. For additional information, see Operation Supplement Safety’s (OPSS) “Are there any safe supplements to help me lose weight?” Furthermore, women looking to enhance their performance may turn to dietary supplement products. OPSS has additional resources for competitive athletes to search for particular products that are certified, as well as helpful red flags on what to avoid.
Some women’s nutrient needs differ from those of men, and they can vary over the course of a lifetime. From adolescent girls, to women of childbearing age, to women over 50, these needs change based on the demands of the physiological changes that occur in the body. One thing is certain: A variety of nutritious food is really the spice of life and should be the basis for fueling all of life’s stages.
