Although most weight-related health information you see concerns weight loss, gaining weight is just as difficult for some people. If you have been underweight your whole life or are recovering from an illness, putting on a modest amount of weight may improve your health and energy levels substantially. Getting adequate amounts of all essential vitamins can help your body maintain a healthy weight.
You may be underweight for a variety of reasons, such as fast metabolisms, inadequate nutrition and simply not eating enough calories for your height and activity levels. In some cases, illness and chronic conditions can prevent your from absorbing food nutrients properly.
Your first effort should be to increase your caloric intake. Concentrate on nutritionally dense foods such as lean protein, healthy fats and high-calorie fruits to get the most energy out of the smallest volume of food. A quality multivitamin may contain as much as 100 percent of your body's daily requirement for those vitamins, ensuring that your body gets what it needs for optimal health without adding even more bulk to your diet.
If you have a chronic condition or illness that is affecting how your body absorbs nutrients, you may need medical treatment to help you get back to a healthy weight. Conditions that affect the stomach and digestive tract can lead to problems with how certain vitamins are absorbed. Your doctor can prescribe treatment such as oral vitamin supplements or getting a vitamin injection if necessary.
A single vitamin may not provide the nutritional boost you need to gain weight, but taking a daily multivitamin can help fill the gaps in your diet to help you reach your goal. Ask your doctor to recommend a multivitamin that is best for you. Read the labels on individual brands; a quality multivitamin should include at least all of the B vitamins, plus vitamins C and E. Look for one that also includes vitamin A -- a 2002 study in the "American Journal of Clinical Nutrition" found that multivitamins that included vitamin A helped some women gain more weight than a multivitamin without this nutrient.
