I second or third the not using Whey, But try adding in some leafy greens, good nutrients carbs and protein. Your body likes plant based protein better so use rice, pea or hemp. Look out for processed isolates, they dont absorb well. If its working for you, good on ya!

Vegetable proteins are some of the worst absorbing (and more expensive) proteins that you can buy in supplement form. They have a much lower bioavailability than whey protein. Other good alternatives to whey are casein and egg protein.

I am not saying that supplemental forms of protein are better than real food. That is not the case. You do not receive any other macro or micro nutrients in most whey protein powders.

That particular study that was posted was done on certain brands of proteins which showed some had high levels of heavy metals. Like most studies, the information was not accurate due to the fact of the varying serving sizes between the different brands. There were some that were extremely high in comparison to the serving sizes that were given (Muscle Milk and Myoplex).
