Hi Protein requirement for you can be met with  balanced diet and dairy products,  Whey protein in India are not reliable as in content mentioned and actual composition because there is no strict regulations for these neutraceutical products as required for medicines. Can take eggs according to food preferences Even after all the efforts with diet and feel diet is poor due to some reasons , can go for proteins supplied by pharma companies because they are more regulated than commercial whey products. Or if have doubts still consult nutritionist for better advice
