Going to try this. I have the Dymatize Vanilla, and while it's good, I find it a bit too sweet (even with 1g sugar/serving). Isopure had the perfect flavor (no sweetness) until they went and changed the formula, so I had to switch it up.

I really like isopure zero carb, it’s good quality protein and I can add my own trigger-avoiding flavors.

100% agree. Been using this stuff for YEARS. This new batch in the white tub is grainy, salty, leaves residue and thinner. Normally when I mix this with my coffee it's creamy and frothy, this shit is like water. I really miss the previous one and will be returning this bottle. Looks like I'll be giving the Whole Foods kind a try.

Unflavored protein powder is my new holy grail. Dump it on literally every meal.

I don't use a full scoop. It's usually half in my breakfast because it's already very saucy, so it mixes super well (Shakshuka) and then 1/4th in my lunch and dinner. And the 1/4th is so small that it tends to just mix out naturally without changing the texture too much. Or like I'll put a little bit in my milk for my coffee before frothing etc. The trick I found was to just spread out your one scoop a day everywhere that it could mix (cereal, spaghetti, mexican bowls, etc.) I'm very "one pot meal" But I'm assuming even in rice or mashed potatoes it shouldn't drastically alter the texture of anything.

Whey isolate (isopure), but I'm assuming any type of unflavored protein would work

Isopure zero carb is pretty solid, tastes like nothing which is what you want. I mix it into oatmeal and it doesn't change the flavor at all

I use Isopure unflavored whey isolate. It’s spendy but amazing.
