Whey is a byproduct of making cheese. It is a thin, milky liquid that contains high levels of protein, proteins that turn out to be easily absorbed, more so than proteins from meat, soy or vegetables. In the past, whey was often discarded or used as animal feed but the market for this product has grown. It is used as an additive in many processed foods and is made into protein supplements.

Whey protein isn’t available in my country, all we have imported whey jars from US or UK that is highly expensive for my budget (being a student doing part-time job) and I really want a protein supplement cause I am an ectomorph skinny guy. The thing is that a dairy company (in my city) sells 25Kgs bags of whey powder to different other companies which is quite cheap as compare to important isolate protein powders, but do you think raw whey powder coming from factory can give equal amount of protein as compare to those expensive 2Kg Jars?
