4 Most Common Vitamin Deficiencies

The four most common vitamin deficiencies include vitamin D, B6 and B12, and folic acid. Other common nutritional deficiencies include iron, iodine, magnesium, and calcium. Most of the American population is deficient in nutrients. This is mainly due to the typical western diet, which consists of packaged or processed foods, red meat, foods high in saturated fats and salty snacks. Additionally, the diet is also low in fruits and vegetables. The four most common vitamin deficiencies in the United States include vitamins D, B6 and B12 and folate.

Vitamin D

Vitamin D plays an important role in strengthening bones and muscles. It also acts as a protective agent against cancer and diabetes. There are two ways to get vitamin D, sunlight and food. Food sources of vitamin D are few but include fish-liver oils, fatty fishes, egg yolks, liver and mushrooms. In the United States, dairy products, such as milk, yogurt and other foods (soy milk) are commonly fortified with vitamin D.

Folic acid

Folic acid is one of the most important nutrients needed during pregnancy and infancy. The U.S. Food and Drug Administration (FDA) mandates folic acid be added to all cereal grain products to prevent neural tube defects in children. Dietary guidelines recommend that every woman should ingest 400 mg of folic acid daily in addition to food sources containing the nutrient. Folic acid can be found in good quantities in foods, such as broccoli, brussels sprouts, leafy green vegetables, peas, chickpeas and kidney beans. Some breakfast cereals are also fortified with folic acid.

Vitamin B6 or pyridoxine

Vitamin B6 is a nutrient that is vital for brain development in a growing fetus and children, especially toddlers. People with kidney disease or intestinal disease that affects the absorption of nutrients are most likely to develop a deficiency of this nutrient. Food sources of vitamin B6 include chicken, fish, chickpeas and bananas. Several breakfast foods items are also fortified with the nutrient.

Vitamin B12 or cyanocobalamine

Vitamin B12 is an important nutrient required for the formation of red blood cells and to maintain the health of nerve cells. Deficiency of this nutrient can result in anemia, sore tongue, depression and a tingling sensation in the limbs. Vitamin B12 is found abundantly in animal-based foods, such as meat, fish, milk and poultry. People who are vegans or those who suffer from intestinal issues are particularly at risk of B12 deficiency.
