Vitamin B Complex Types & Foods

Vitamin B complex includes thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folate, and cobalamin. Let us take a closer look at them in detail below.

• B1 (Thiamine): This compound converts sugar and carbs into usable energy, has neurological benefits, and helps maintain a healthy blood flow around the body. It can be found in whole grains, dark green vegetables, such as kale, as well as milk and eggs.
• B2 (Riboflavin): Like B1, this nutrient is needed for metabolism and it is also good for eye health. It can be found in the same food sources as B1; whole grains, green vegetables, milk, and eggs. 
• B3 (Niacin): B3 is another essential compound for the metabolism of nutrients into ATP, the fuel for human cells. It also helps the digestive system. It can be found in red meat, chicken, whole grains, fish, and peanuts.
• B5 (Pantothenic Acid): B5 is also important for energy production and for the processing of hormones that keeps the human body balanced. It can be found in strawberries, grapefruit, sunflower seeds, yeasts, meat, yogurt, and eggs. 
• B6 (Pyridoxine): B6 breaks down stored glucose and regulates body acids in the blood. It can be found in chickpeas, tuna, whole grains, beef, chicken, watermelon, salmon, and spinach.
• B7 (Biotin): B7 is involved in the conversion of food into energy and helps the body produce fatty acids, which maintain cell health.
• B9 (Folate): B9 is also called folic acid, and fosters the growth of red blood cells. It is commonly taken by pregnant women to reduce the risk of birth defects. It can be found in fortified cereals, whole grains, citrus fruits, green leafy vegetable, meat, fish, and beetroot.
• B12 (Cobalamin): B12 is intrinsic for the maintenance of healthy blood cells and nerves. It also helps produce DNA and prevents some types of anemia. The primary natural sources of B12 are from animals – meat, fish, and dairy. It can also be found in fortified breakfast cereals and nutritional yeasts.
