WPC has low levels of fat and low levels of carbohydrates. The percentage of protein in WPC depends on how concentrated its. Lower end focus tends to have 30% protein and higher end up to 90%.
Whey protein isolate
WPIs are further processed to eliminate all the lactose and fat. WPI is generally a minimum of 90% protein.
Whey protein hydrolysate
It is the predigested type of whey protein because it has gone through partial hydrolysis which is an essential process for the body to absorb protein. WPH does not need as much digestion as the other 2 forms of whey protein.
Weight Loss

Asthma
It can also improve kids’ immune responses who have asthma disease. One study that was published in the International Journal of Food Science and Nutrition involving 11 kids, found that kids having asthma who were given 10-gram whey protein twice, daily for 1 month got an improved immune response.
