Hello,
For some it is effective and for some ineffective. It only increase weight not recover your cause of underweight and even Deficiency in body. As you have to take it life time and if by chance you stopped this. You will come back again.
So better to follow a healthy diet for weight gain instead of these shortcuts.
Shortcuts are not good.
Before prescribing anything we need some information like your vitals ,Family history, Lifestyle, occupation, medical history, daily routine and many more.
