Unflavoured just means there's no flavour added to it, it's just the natural flavour of the whey. Tasting notes vary hugely between people, they have sample packs so you can just try a bunch without committing to a bag. The Canadian Protein ones I tried 2 years ago were New Zealand Whey concentrate, New Zealand Whey isolate, whey protein isolate, hydrolysed whey protein isolate, premium whey blend, premium whey isolate, egg white protein powder. Some were absolutely vile (to me, plenty of other people don't mind the taste), others almost disappeared if you mixed them into hot chocolate or a smoothie. From my tasting notes, the hydrolysed whey and premium whey isolate disappeared the best in chocolate milk. New Zealand Whey and whey isolate worked basically fine mixed with lemonade. The other combinations had varying levels of milky/chalky/vomity/weird taste to me but that's very individual.
I found the regular whey protein isolate and premium whey isolate to be pretty similar when mixed in water, the regular had a slightly stronger weird taste that took more other stuff to mask than the premium. But the textures and ease of mixing were the same in the batches I received.
I ordered unflavored and it's pretty disgusting, but I got used to it. Maybe someone else can chime in
I almost exclusively use unflavoured unsweetened protein powder, I really like Canadian Protein (they do ship elsewhere if you are not Canadian). It's a really solid product and they have different lines for different preferences and budgets, they put really good sales on from time to time, and you can access the batch test analysis for every bag you purchase. They do also have some really yummy flavours too, I like buying their little sample packs so I can try lots of different ones without committing to a whole bag.
See how you feel Canadian Protein ranks for cost. It’s where I order from and I feel it’s a really good deal. It’s not super cheap, but it’s good quality and a good price.
Its the cheapest whey protein you can get in Canada, and Costco sells it cheaper than the manufacturer. We always stock up when its on sale because I usually have it as my afternoon snack at work to hit protein goals. Taste is alright, very artificial sweetener tasting but its fine. The gum they use in it makes it very thick when you mix it with greek yogurt. Doesn’t mix that well compared to other brands like Canadian Protein. It is also much thicker and lumpier. A shaker bottle and letting it sit for a bit can help for this. Sort of the best bang for buck, but not especially premium. We splurge a little for 2 Pure from Chokolat in Calgary because it has no gums and mixes very well with greek yogurt. But its 2.5x the price of Leanfit.
Another vote for Canadian protein! Their strawberry milkshake and cinnamon bun flavour are my favourite
