Is Kaizen Naturals 100% Vanilla Whey Isolate Tree Nut Free?

It mixes pretty well, it tastes good for something made with natural flavours and sweetener it doesn’t have a weird Stevia aftertaste.  I have never been a big fan of Kaizen, I’ve never knowing them to make truly high-quality products but never horrible ones either. They say the whey protein comes from grass fed cows, hopefully it’s Canadian milk whey and not whey imported from China that usually is adulterated and contaminated. I didn’t get any gassiness or bloating.
