B Vitamins and Their Role in the Body

B vitamins are involved in the regulation of almost all systems. If you have any health issues, there is a high chance you are deficient in one of the B vitamins.

  • Vitamin B1 (thiamine): Participates in carbohydrate metabolism and helps the body convert food into fuel. It is also important for the normal functioning of the nervous system.
  • Vitamin B2 (riboflavin): Helps produce a coenzyme involved in cellular respiration. It is important for healthy skin, eyes, and the nervous system.
  • Vitamin B3 (niacin): Participates in the metabolism of fats, proteins, and carbohydrates. Helps reduce bad cholesterol in the blood.
  • Vitamin B5 (pantothenic acid): Participates in the synthesis of fats, proteins, and hormones. Helps the body convert food into energy.
  • Vitamin B6 (pyridoxine): Essential for normal brain and nervous system function. Participates in the metabolism of amino acids and haemoglobin production.
  • Vitamin B7 (biotin): Important for healthy skin, hair, and nails. Participates in the metabolism of fats and carbohydrates.
  • Vitamin B9 (folic acid): Essential for the formation of DNA and RNA, which is important for cell division and tissue growth. Particularly important during pregnancy.
  • Vitamin B12 (cobalamin): Participates in the formation of red blood cells and supports the health of the nervous system.
