welcome to HealthcareMagic !
forte is a multivitamin
containing B1; B6;B12 (cyanocobalamine) as a combination and Neurobion-plus contains B2;Niacinamide and B12 in form of Methylcobalamin
.The basic difference is the content of Vitamin B12
and the forms of the compound and the dosage of B12 is more in Neurobion-plus. Based on your indication the formulations usage differs. Hope I have answered your query. If you have any further questions, I will be happy to help. Thanks
