Vitamin B complex is required for a wide range of processes in the human body. Its shortage can also result in a number of illnesses, including persistent neurological disorders. Biochemically, distinct structures are grouped together under the B complex based on their natural prevalence in the same type of food and water solubility. Because humans cannot synthesize vitamins in the B complex on their own and because these vitamins are easily excreted from the body through urine, they must be consumed on a regular basis to maintain energy production, DNA/RNA synthesis/repair, genomic and non-genomic methylation, and the synthesis of numerous neurochemicals and signaling molecules. B complex insufficiency is typically caused by one of four factors: a high consumption of processed and refined foods, a lack of dairy and meat-based foods in the diet, excessive alcohol consumption, decreased absorption from the gastrointestinal tract, or poor storage and usage by the liver. 1
According to clinical research, parenteral administration (intramuscular or intravenous) is recommended over alternative drug delivery methods in emergency conditions because it avoids first-pass metabolism, offers consistent therapeutic concentrations, and improves dose bioavailability. 2 It can also be employed when the oral route is not an option.
Preparation of pharmaceuticals:
Each 30 mL vial contains 100 mg of vitamin B1 as thiamine hydrochloride, 2 mg of vitamin B2 as riboflavin-5-phosphate sodium, 100 mg of B3 as niacinamide, 2 mg of vitamin B5 as dexpanthenol, and 2 mg of vitamin B6 as pyridoxine hydrochloride.
B vitamins are required for the proper functioning of the methylation cycle, DNA synthesis, phospholipid repair and maintenance, and are usually required for healthy skin, muscles, brain, and nerve functions.
3 The different functions are outlined below, however they usually operate together to accomplish the desired effect.
B1 vitamin (Thiamine)
It is essential for energy metabolism, immunity enhancement, and nervous system function. It can aid in the prevention of type 2 diabetes, cardiovascular disease, some eyesight and renal illnesses, and neurodegenerative diseases such as Alzheimer’s disease.
B2 vitamin (Riboflavin)
It is a potent antioxidant that helps to maintain healthy blood cells and promotes metabolism.
B3 vitamin (Niacin)
Niacin is essential for the healthy operation of the neurological and digestive systems. It, like other vitamins in the family, is required for energy production and fatty acid metabolism. It also promotes the health of the skin, nails, and hair.
B5 vitamin (Pantothenic Acid)
Pantothenic acid is required for proper central nervous system development. It is involved in energy generation as well as the formation of amino acids, blood cells, vitamin D3, and other fatty acids via several metabolic and anabolic cycles.
B6 vitamin (Pyridoxine)
Vitamin B6 plays an important function in the synthesis of neurotransmitters and is necessary for optimum mental health. It also has an immediate impact on immunological function. It aids in the metabolism of amino acids and is a required co-factor in the folate cycle, a shortage of which can result in anaemia. Epidemiological evidence suggests that the established vitamin B dosages only serve to avoid marginal insufficiency, and that greater dosages than those supplied by RDA could provide additional benefits. 45
