Abundant in green vegetables, whole or enriched grains, dairy, and meats, B vitamins help promote a healthy metabolism and are also linked to a reduced risk of stroke, research shows.
The B vitamins work together as a team. Some of them help cells burn fats and glucose for energy, while others help with the production of serotonin. They work intricately together behind the scenes with amazing results. Found naturally in meat, leafy greens, dairy, beans, peas, and whole or fortified grains, B-complex vitamins help your body make energy from the food you eat, form red blood cells, and play an essential role in certain bodily functions. Let's take a closer look at the benefits, signs of deficiency, and food sources for each of these B-complex vitamins.
What is vitamin B-complex?
Vitamin B complex is composed of eight B vitamins:
- B-1 (thiamine)
- B-2 (riboflavin)
- B-3 (niacin)
- B-5 (pantothenic acid)
- B-6 (pyridoxine)
- B-7 (biotin)
- B-9 (folic acid)
- B-12 (cobalamin)
Each of these essential vitamins contributes to your overall bodily function. They all play a vital role in maintaining good health and well-being.
B-1 (thiamine)
It helps the body use carbs from food to produce energy. It's needed for the health of the brain, muscles, and nervous system and it is critical for the growth, development, and function of cells in the body.
B1 is found in whole-grain cereals, yeast, beans, nuts, and meats. Too little vitamin B1 causes Beriberi, a disease affecting the heart, digestive system, and the nervous system. Beriberi is found in patients who are malnourished, and in those who are heavy drinkers of alcohol. Symptoms of beriberi include difficulty walking, loss of sensation in the hands and feet, and paralysis of the lower legs and it may even lead to congestive heart failure. People who consume large amounts of alcohol should take a vitamin B complex supplement to be sure they get enough B1.
B-2 (riboflavin)
B2 works with other B vitamins (helps convert B6 into a usable form and aids in niacin production) and also helps convert food into energy. It's also needed for red blood cell production and growth and keeps the eyes, nervous system, and skin healthy.
B7 deficiency can lead to hair thinning or loss, skin rashes around the eyes, nose, mouth, or other mucous membranes, dry eyes, brittle nails and muscle pain. Common food sources of vitamin B7 include beef liver, egg yolk, wheat germ, pork, beef, sunflower seeds, sweet potato, almonds, whole-grain foods, sardines, spinach, and broccoli.
B9 (Folic Acid)
B9 helps your body make red blood cells. It is needed to help cells make and maintain DNA and, when taken during pregnancy, it reduces the risk of birth defects in the brain and spine, such as spina bifida.
Teens and women who are pregnant or planning to get pregnant may find it difficult to get enough folate, but this B vitamin is vital to a baby's health and development.
Naturally occurring folate is found in many sources, including dark-green leafy vegetables, asparagus, brussels sprouts, oranges, nuts, beans, and peas. In addition, folic acid is added to many fortified foods such as cereals and breads.
B12 (Cobalamin)
B12 helps keep the nervous system and red blood cells healthy. It is required for the formation of red blood cells and DNA and it plays a very important role in protein metabolism.
As many as 15% of people in the United States have a vitamin B12 deficiency, which can lead to anemia. Symptoms of B12 deficiency include weakness, fatigue, constipation, weight loss, and loss of appetite. B12 deficiency can also damage the nervous system and can cause depression, confusion, and dementia.
Vitamin B12 is not naturally occurring in plant foods, so vegetarians and vegans may not get enough in their diets and may need to take a B supplement. Natural sources rich in vitamin B12 are dairy products, fish, meat, and, in particular, beef liver and clams. This type of vitamin B can also be found in fortified items like breakfast cereals and nutritional yeast.
How can you tell if you’re deficient?
Most people get enough B vitamins by eating a balanced diet. However, it’s still possible to be deficient.
The following symptoms may be a sign that you’re not getting enough B vitamins:
- skin rashes
- cracks around the mouth
- scaly skin on the lips
- swollen tongue
- fatigue
- weakness
- anemia
- confusion
- irritability or depression
- nausea
- abdominal cramps
- diarrhea
- constipation
- numbness or tingling in the feet and hands
Your doctor can determine if you are deficient in one of the B vitamins and may prescribe a vitamin B-complex supplement. A varied and balanced diet is essential to avoiding a B vitamin deficiency and reaping the health benefits of these important vitamins.

B-Complex supplements: YES or NO?
Truth is that getting the recommended amounts of vitamins each day is an important part of the nutrition equation, and most of us don’t get enough of them.
While most people who eat a varied diet get enough B vitamins from food, some people are at an increased risk of deficiency, particularly those who are over the age of 50, take antacid medication, or have celiac disease, Crohn's disease, gastritis, or other digestive disorders.
If you have had stomach or weight loss surgery, drink alcohol regularly, or follow a vegetarian or vegan diet, you may be more prone to a deficiency.
Pregnant and breastfeeding women may need more vitamins B6, B12, and folic acid.
