Types of B vitamins and Their Functions

B vitamins are extremely important for the human body to function properly. Unfortunately, though, the body does not produce them on its own. Therefore, people obtain B vitamins from food and supplements, including our itSpray solutions, BOOSTit and CHARGEit. Keep reading to learn about the types of B vitamins and their functions.

Here are the 8 Types of B Vitamins and Their Functions according to the Better Health Channel

Thiamin (B1):

  • Helps convert glucose (sugar) into energy and plays a role in nerve function
  • Consuming too much alcohol can cause a vitamin B1 deficiency.
  • A deficiency in this vitamin can cause problems for the heart, muscles, gut, and nervous system.


Riboflavin (B2):

  • Aids energy production in the body
  • Helps vision and skin health.
  • A lack of this vitamin is rare but is also caused by excessive alcohol consumption.


Niacin (B3):

  • Converts carbs, fat, and alcohol into energy for the body
  • Important for skin health as well as the nervous and digestive systems
  • Vitamin B3 deficiency is known as pellagra, which is caused by too much alcohol and corn consumption.
  • Pellagra can cause dementia, diarrhea, and dermatitis.
  • Too much vitamin B3 can cause issues such as liver damage


Pantothenic acid (B5):

  • Metabolizes carbs, proteins, fats, and alcohol
  • Produces red blood cells and steroid hormones
  • Deficiency is rare because of how common this vitamin is in food.


Vitamin B6 (pyridoxine):

  • Metabolizes carbs and proteins
  • Creation of red blood cells and brain chemicals
  • Important to the brain, immune system, and steroid hormone activity
  • Deficiency is rare, but once again, too much alcohol increases the risk. Women, the elderly, and those with thyroid disease are also at risk.
  • Too much vitamin B6 can cause nerve damage.


Biotin (B7):

  • Metabolizes energy and amino acids
  • Synthesizes fat and glycogen
  • Too much biotin can cause high cholesterol.
  • Deficiency is rare because of how common this vitamin is in food


Folate or “folic acid” when included in supplements (B9):

  • Forms red blood cells and supports the fetal nervous system
  • Also helps with DNA synthesis and cell growth
  • Important for child-bearing women
  • An excess of folic acid can cause intestinal issues and illness.


Cyanocobalamin (B12):

  • Important to brain function, nerve cells, and the formation of red blood cells
  • Helps break down fatty acids and amino acids for energy
  • The elderly and people who follow strict vegan diets are at high risk for vitamin B12 deficiency.
