There has been a lot of press lately about Vitamin D deficiency, but what about B vitamins? B vitamins are found naturally in many foods and also added to other foods and beverages (these are considered enriched or fortified). From peanut butter to pork, it seems like it would be easy to meet your vitamin B needs. However, some Americans, especially those over 65 years of age, fall short either from consuming too little of a certain vitamin or from a decrease in absorption. The most common deficiencies noted in this age group are vitamins B12 and B6 .
The B vitamins are grouped together because they work together. While each B vitamin plays a unique role in our body, they work together to produce energy within our cells. Therefore, it is important to ensure that you are meeting your need for all B vitamins and not taking one or two B vitamins alone (unless directed by a physician). Additionally, excess folic acid can trigger symptoms of a vitamin B12 deficiency; therefore the balance between these two vitamins in our body is very important. If you think you may fall short, consider a B complex or multivitamin with all B vitamins.
B Vitamins and Their Food Sources
Vitamin |
Function in the Body |
Top food sources |
Thiamin (B1) |
Helps produce energy from carbohydrates |
Pork, beef liver, enriched rice, fortified cereal, bread |
Niacin |
Helps the body use sugars and fatty acids; helps enzymes function |
Fortified cereals, swordfish, tuna, salmon fish, chicken, wheat flour, pasta, malted drink mixes with added nutrients |
Pyridoxine (B6) |
Helps the body make nonessential amino acids (nonessential means the body can produce them); converts tryptophan into serotonin; helps produce other body chemicals (insulin, hemoglobin, antibodies) |
Chicken, fish, pork, peanut butter |
Riboflavin (vitamin B2) |
Plays a key role in the metabolism of fats, ketone bodies, carbohydrates, and proteins |
Beef, turkey, fortified cereals, vanilla fast food shake, roasted duck, milkshakes |
Folate (folic acid or folacin) |
Helps produce new cells in the body; works with B12 to produce red blood cells; helps decrease the risk of delivering a baby with neural tube defects; may help control homocysteine levels |
Enriched rice, fortified cereals, cornmeal, turkey, wheat flour, chicken, lentils, cowpeas, orange juice, beans, chickpeas, okra |
Vitamin B12 (cobalamin) |
Works with folate to make red blood cells; helps the body use amino acids (components of protein) and some fatty acids; is part of many body chemicals |
Mollusks, beef, turkey, clam chowder, chicken, Braunschweiger sausage, Alaska king crab, salmon, sardines, fortified cereals, trout, herring, pollock |
Biotin |
Helps metabolize proteins, carbohydrates and fats |
Eggs, wheat germ, peanuts, cottage cheese, whole-grain bread |
Pantothenic acid |
Helps metabolize proteins, carbohydrates and fats |
Fortified cereals, mushrooms, chicken, beef, turkey, duck, sunflower seeds, couscous, enriched rice |
*Choline |
Assists with transporting fats in the body and helps make substances that form cell membranes; helps make the neurotransmitter acetylcholine; plays a role in liver function and reproductive health |
Beef, chicken, turkey, eggs, duck, eggnog, veal, tomato paste |
*Choline is a vitamin like substance that is typically grouped with B vitamins.
According to the Food and Nutrition Board, Institute of Medicine, 10 to 30 percent of older people have trouble absorbing B12 from food and those older than 50 should consume foods fortified with B12 or take a supplement containing B12.
Keep Those B’s In Your Food
Keep in mind that the water-soluble B vitamins are destroyed to an extent during food preparation, processing and handling. Try these tips to keep vitamins in the food you will eat:
