Whey Prot. Sup. dangerous for my health?

Dear Team, Till 2019 end to March 2020 my weight was 55-57 KGs so as per my height which is (5'11 FT) I was underweight but then I started following home diet and medium intensity exercise then I had gain 8-9 KGs but now because of busy office life and busy schedule I lost 5-6 KGs. But now again I want to start high intensity workout and follow diet as well but now because I need to increase my calories I need supplement, My question is that is Whey protein is good for my health?? and is my lever can absorb that pretty well, sometimes I have face gas and bloating issues, and my as per I have know my lever from childhood I have a problem of digest spicy and oily foods so is consume whey protein is good for my health??? And if YES so which precautions I need to take to avoid any digestion, gas and bloating and any serious lever damage or failure issues??? And if No please provide me any alternatives of it?? Thanks and Regards Suraj S Mohite
