Q: I am suffering from acute vitamin B complex deficiency. I have been taking Renerve plus injection once in 5 days sometimes. But the problem is that I always feel very weak. The doctor told me to take this injection or mcbm-69 tablets daily to overcome this problem. But even after all this I still have the same problem. Is there a permanent solution to avoid this? Can an operation or drug help me?

A:Vitamin B complex comprises a number of vitamins that exist as a family of eight water-soluble vitamins. These are grouped together as they share many similarities like chemical properties, their distribution in nature and the physiological functions they perform as coenzymes in the body where they facilitate metabolic reactions. They include vitamin B1 (thiamine), B2 (riboflavin), niacin (nicotinic acid), B6 (a group of related pyridines), pantothenic acid, biotin, folic acid and B12 (cyanocobalamin). Their deficiency may be due to a) Cooking – heat denatures the vitamins and most people do not eat enough raw foods in the diet, b) Malnutrition, c) Diet rich in processed foods and refined sugar, d) Drugs – some medicines may lead to deficiency and e) Toxins.
