In my opinion, there are three main criteria when choosing whey protein.
1. Make sure it is made entirely with whey isolate, not concentrate. The thing is that isolate is the more expensive version of whey, since it is purified and has no lactose in it.
2. Choose the one without artificial flavours and additives – those things are unnecessary, and bring nothing good for your health.
3. Choose the one without artificial sweetners.
For me, N2BM's Isolation fits perfectly for those criteria, so it is a great choice. Besides, it has a great price too.
