Casein digests much slower and will provide your body with a constant flow of nutrients for a longer amount of whey protein powder time.American was ranked one of the best tasting supplements on the market and is available in the choice of flavors.
Errr true... but it's made from milk. Ok if you're vegetarian, but I'm guessing he's after a vegan one!
I spent ages reading the fine print, comparing amino acid profiles and got way too obsessed with it I just had to take a step back! They're all pretty even, but a blend that uses protein from multiple plant sources seems to have a more balanced profile. I recommend Vega, which you can buy from the links on the main site. You can also get it from websites such as vitacost and iherb along with plenty of other vegan proteins to browse through. The store on bodybuilding.com has a plant protein section too.
Flavor-wise I've found anything with pea protein can go quite thick if you don't use enough water (this actually makes an awesome mousse!) and rice is very "dusty" feeling in the mouth. You can't drink them and expect them to taste AMAZING but with a little perseverance you adapt to the flavor. I love them now!
The ones I have tried are Vega - probably the best amino profile. Mixes quite thick, vanilla flavor is subtle, chocolate has a very rich cocoa flavor. Overall 9/10.
Nitrofusion - Pea/artichoke/amaranth/quinoa protein - same consistency as Vega, more of a subtle flavor in the chocolate. I'm a sweet tooth and found this one a little nicer with an extra teaspoon of stevia added. Overall 7/10
Sunwarrior - Rice protein. Once I got used to the chalky feeling, I actually really loved the tase of this one, and I have to say flavor wise it's been my favorite, doesn't get as thick as the others and the chocolate flavor is well balanced. I found the amino profile beat Vega on some singular amions, while it lacked in others. I give this an 8/10
The others I would be interested in trying are RAW protein (looks great, but the fact that it's unflavored scares me!) and Lifetime Basics Plant protein looks good too.
You might want to have a look on those websites, see what's out there and just try a few till you find one that suits you. You could also try emailing companies for samples.
Hope this helps a little, sorry it turned into a bit of a rant!
