Soy Protein is a type of protein fit for vegetarians which makes for an affordable alternative to dairy based proteins. As well as not containing dairy products it is also suitable for people with lactose intolerance who can find soy protein easier to digest. An alternative to the use of soy protein for people with difficulty digesting dairy proteins would be combining a dairy based protein product containing either casein or whey, with the use of a probiotic product such as Gut Health by RPN.
