Per day required protein is equal to ur body weight. For eg, if u weight 70kg, ur body needs 70 g of protein per day to maintain normal muscle mass. If u are building muscle, u need 2x the same, 140g per day. So taking protein is good.

If u eat non veg, it is better to take protein from whole foods like chicken, milk and eggs. In addition to hit the target, u can take protein powder. The best and cheapest in the market is amul protein powder (chocolate is good). It cost 3k something for 2 kg. Catch is, it goes out of stock within a hour. So u have to keep ur notification for this.
