Chocolate, matcha, almond, grain. So many flavors that picking is half the fun! All four are good, so if you make me choose just one I can't decide,, but personally chocolate and grain are really good, I think..?

Protein content and taste by flavor
Almond: tastes like an oat latte with milk
The almond flavor has 22g of protein and 4.6g of fiber. The writer says mixing it with milk tastes just like an oat latte.
I really love almond milk normally. So whenever I go to a café I always switch to oat, and this with milk is exactly an oat latte,, of course there's no caffeine, but it's great for cutting down on caffeine at the same time :)

Grain: just like misugaru
The grain flavor has 23g of protein and 6g of fiber. It tastes exactly like misugaru (roasted multigrain powder drink), so the writer recommends it to anyone who likes a nutty flavor.
Is there anyone with a grandma's taste buds here..? That's me..^^ hahaha,, this is basically identical to misugaru, so if you like nutty flavors you'll definitely like it!!!
Matcha: pleasantly bitter
The matcha flavor has 22g of protein and 5g of fiber. Matcha is so hot right now that people even say "matchacore"! It's pleasantly bitter and honestly delicious!!
Chocolate: a safe pick everyone likes
The chocolate flavor has 20g of protein and 5.2g of fiber. Honestly, how could this be bad..? Everyone from kids to grandparents likes chocolate, so there are no haters! If you want a flavor that never fails, this is it!!!

Does Switch On Protein Shake taste good with water?
It's good with soy milk or milk, but the writer simply mixes it with water. In the writer's opinion, it tastes great with just water.
It's good mixed with soy milk or milk too, but I just keep it easy and mix it with water. It's delicious with just water, I swear...

Best of all, I can have it easily whenever I feel like it, so it was super convenient and nice!

How are the flake texture and fullness?
There are flakes inside Switch On Protein Shake, so you get something to chew. The writer felt that the chewy bits keep you feeling full longer.
There are flakes inside like this, so it's nice and chewy and twice as nutty!! Since there's something to chew, it seemed to keep me full longer, which I liked!!
When you drink it, give it a good shake shake like this~~ The Switch On diet isn't hard, so let's all go hard on a diet for the coming summer!
