Cellular metabolism depends on the complex of B vitamins. Each member of the B complex either has a coenzyme activity for important metabolic processes or is a precursor needed to make a coenzyme.

B VITAMINS

B1 (thiamine) is the essential coenzyme for carbohydrate metabolism but also for the production of acetylcholine.
Riboflavin (B2) is a precursor to the formation of coenzymes after being first converted to its bioactive form (riboflavin 5-phosphate) for use by the body. Vitamin B2 in the form of riboflavin 5-phosphate serves as a component of additive groups (FAD and FMN) of flavoproteins that participate in oxidation-reduction reactions in numerous metabolic pathways, as well as in the production of energy through the respiratory chain.
B3 (niacin) is a precursor to coenzyme A and plays an important role in energy transfer reactions for the metabolism of sugars, fats and alcohol.
B5 (pantothenic acid) is a precursor for the production of coenzyme A, which is needed for the metabolism of many molecules, eg amino acids, fatty acids, phospholipids, etc.
B6 (pyridoxine) in the form of pyridoxine 5 phosphate is an important coenzyme for decarboxylation (deamination of amino acids, eg 5-hydroxy-tryptophan into serotonin, coenzyme in transaminase reactions (the body is not supplied).
B9 (folic acid) interacts with B12 to synthesize DNA which is an essential component for all cells in the body.
B12 (methylcobalamin) which is its active form, is the essential coenzyme for the processing of carbohydrates, proteins and fats
and participates in redness. It is still needed to maintain the nerve sheaths.
B8 (inositol) is an important key intermediate of the second messengers, but also a dominant component of cell membrane phospholipids involved in many biological processes.
All members of the B vitamins group work together and a key feature of Doctors formulas' B-Complex formula is that it contains all the B vitamins.

They contribute to the normal functioning of metabolic processes aimed at producing energy, protecting cells from oxidative stress and reducing fatigue and tiredness.
