Blackmores Mega B Complex provides high potency B complex to support cellular energy production.  The B vitamins are a group of water-soluble vitamins commonly found together in foods. They play an essential role in the metabolic processes of all living cells by serving as coenzymes in the conversion of carbohydrates, proteins and fats from the diet into energy.  The normal function and maintenance of the nervous system relies on the presence of the B-group vitamins for the production of hormones and neurotransmitters.  As the B-group vitamins are water-soluble, the body does not store them in large amounts, and it is necessary to consume them in the diet. Stress, strenuous physical activity, and overindulgence in alcohol may all increase an individuals requirements for key B-group vitamins, so supplementation may be beneficial in these circumstances.
