Neurobion Forte is a B‑complex supplement combining six B vitamins—B1 (thiamine), B2 (riboflavin), B3 (nicotinamide), B5 (calcium pantothenate), B6 (pyridoxine), and B12 (cyanocobalamin)—marketed for supporting nerve health and addressing vitamin‑B deficiency symptoms like tingling and numbness. A typical Indian-market composition per tablet is B1 10mg, B2 10mg, B3 45mg, B5 50mg, B6 3mg, and B12 15mcg. These water‑soluble vitamins act as coenzymes in energy metabolism and neuronal function, and excess amounts are excreted in urine. Many people obtain adequate B vitamins from diet; supplementation is most helpful when deficiency risk or confirmed deficiency exists.
