  1. Vitamin B and D are essential for normal function of the body .

    Vitamin B is a complex. It contains a variety of classes like B1,B2,B3,B6,B12 etc. These vitamins act as various co-enzymes in endogenous metabolic reactions and also few have epithelial protective function.

    Vitamin D is a fat soluble vitamin. It is involved in calcium metabolism and bone growth. It works along with parathyroid hormone and calcitonin to maintain normal calcium levels in the body.

    Hence, vitamin B deficiency causes various metabolic syndromes and blocks normal metabolic pathway like hyperhomocysteinemia etc as they (B complex) are also a source of NADPH and FAD ( the backbone of many of the reactions). Also, thiamine (B1) deficiency causes a disease called beri beri. Beri beri can manifest as dry or wet beri beri. Dry beri beri affects the nervous system and wet beri beri the cardiovascular system. There is also another type called infantile beri beri.
    Pellagra is also a B(niacin) deficiency. Characterised by dermatitis, diarrhea and dementia, eventually leading to death.

    Vitamin D deficiency causes rickets in children and osteomalacia in adults. This is characterised by Bowing of knees, characteristic rachitic rosary on the chest etc. It is because of increased bone resorption.

    A well balanced diet is more than enough to make up for the vitamins. But if you’d like to supplement yourself you may go for vitamin B complex tablets. Vit B is a water soluble vitamin and the excess is simply excreted out.

    But be careful for vit D. As this is a fat soluble vitamin, excessive intake will lead to accumulation and will cause another dreaded condition called hypervitaminosis D.
