Hello....
To have a healthy weight gain without any side effects, first don't opt for supplements like protein powders or anything else. Please choose natural foods which are nutrient dense like nuts, seeds, dry fruits, eggs, fish, dairy products, cereals, pulses etc., Just taking healthy foods what ever way and any quantity is also not good. A balanced diet with recommend nutrient allowance according to your basal metabolism along with physical activity helps you to gain weight.
Hope it's helpful....
thank you..
