Do I Need Extra Vitamins if I Take A Multivitamin?

Most people should get all of their vitamins and minerals from their diet. Take extra vitamins if you do not meet the RDA of each vitamin and mineral you need daily.

The supplement industry is booming in the U.S. People spend over 12 billion dollars a year on multivitamins and supplements. With many options available, you may wonder: Which vitamins should I take daily, and which multivitamin is right for me?

Not everyone needs the same things from their multivitamin. One supplement may not meet all of your vitamin and mineral needs. It depends on the vitamins you currently get from your diet.

If you’re concerned that you’re missing certain nutrients, check the foods you eat each week. By paying attention to the ingredients, you can calculate the amounts of each vitamin and mineral you regularly get from your diet.

Otherwise, talk to your doctor or a dietitian to see if any supplements are right for you. In general, people are more likely to need supplements if they:

  • Eat few calories
  • Are older
  • Have undergone bariatric surgery
  • Abuse drugs, including alcohol
  • Don’t eat enough fruits and vegetables

What should you consider when choosing a multivitamin?

It can be hard to find the right multivitamin for you. Keep in mind that the U.S. Food and Drug Administration (FDA) doesn’t regulate supplements, so you need to find a brand you trust. Ask your doctor for recommendations.

Ideally, find a multivitamin that only has the ingredients you’re lacking and not too many extras. You may even want to take a few individual supplements if you’re only lacking one or two things from your diet.

Also, make sure you’re not taking anything with megadoses. Too much of certain vitamins can be toxic for your body.

What vitamins and minerals should you get daily?

In general, make sure you’re getting all 13 essential vitamins, including vitamins A, C, D, E, K, and the eight different B vitamins. Also, make sure to get the recommended daily allowance (RDA) for each of these, as well as essential minerals. Otherwise, you could develop a deficiency, which can lead to health problems.

Vitamin A. Dietary sources include dairy products and orange-colored fruits and vegetables like carrots and mangoes. It boosts your immune system, maintains vision, strengthens bones, and supports organ function.

Vitamin B6. Natural sources include fish, starches, and certain fruits. It helps maintain brain functions, metabolize carbohydrates, proteins, and fats, and produce blood cells.

Folic acid. This B vitamin is important for young females and pregnant women. It helps with fetal development and prevents neural tube defects.

Vitamin C. Found in many fruits and vegetables, it has antioxidant properties that protect cells and promote overall health.

Vitamin D. Sources include sunlight, fish oil, fortified milk, and fortified cereals. It supports the immune and nervous systems and helps maintain calcium and phosphorus levels.

Vitamin E. Found in spinach, nuts, and whole grains, it has antioxidant properties and may reduce the risk of blood clots, certain cancers, and Alzheimer’s disease.
