Your right weight as per your height is 72 KG. Protein powders do not directly help in increasing weight. It is complete package of food intake and exercise along with supplements that helps. Meaning of supplement itself is, it supplements your food, if it is incomplete. But supplements are not food substitutes. So take higher protein-rich foods and do strength training. Avoid processed food.
