There should be no need to supplement protein on a healthy diet. Save your money and buy some fresh organic locally grown food with it : )
That is my opinion, but there is much research and decades of experience behind what I am saying, and I offer it to you as a consideration, and with answering your question honestly and intention of helping. Others will probably ay differently, and you can consider what they have to say as well. I don't claim to know everything, but i feel strongly about this.
Eating whole unprocessed foods is the best we can give our bodies.
Best to you - jv
