Vitamin BWhen people refer to B Vitamins they are essentially referring to water-soluble vitamins (excluding Vitamin C). These include:

  • Thiamine (vitamin B1)
  • riboflavin (vitamin B2)
  • niacin (vitamin B3)
  • pantothenic acid (Vitamin B5)
  • pyridoxoine (vitamin B6)
  • biotin, folic acid and cobalmins (vitamin B12)

At one time it was thought that there was a single Vitamin B but researchers later found that there are many that work independently.  The importance of adequate B Vitamins in the diet cannot be over-emphasised. As water soluble vitamins cannot be stored by the body and any excesses are simply flushed away.

  • normal heart functions

Vitamin B2 (riboflavin) contributes to:

  • normal functioning of the nervous system

  • normal synthesis and metabolism of steroid hormones, some neurotransmitters, and vitamin D
  • normal energy-yielding metabolism
  • normal mental performance

Vitamin B6 contributes to

  • normal cysteine synthesis
  • normal energy-yielding metabolism
  • normal functioning of the nervous system
  • normal homo-cysteine metabolism
  • normal protein and glycogen metabolism
  • normal psychological function
  • normal red blood cell formation
  • normal function of the immune system
  • reduction of tiredness and fatigue
  • regulation of the hormonal system

Biotin contributes to:

  • normal energy-yielding metabolism
  • normal functioning of the nervous system
  • normal macro-nutrient metabolism
  • maintenance of normal hair, mucous membranes and normal skin
