Costco does sell a Fairlife protein drink which is actually pretty good if you can find a good flavor but that's a traditional sports protein type shake, not milk. Fairlife ultra filtered milk is sold in most larger supermarkets. It's real milk in full, 2% and 1%.

The Bragg's Nutritional yeast is described as having a nutty flavor, some call it cheesy, to me it has a bakery bread note. We use lots of it in baked potatoes.
