This is vanilla without the perfume. It’s warm, rounded, and easy to drink every day. The protein comes from baker’s yeast, the same species behind bread and beer, which is fermented and refined into a fine powder. With water the shake stays light. With milk it turns thick and creamy. Each scoop gives you 23.6 g of protein, with all nine essential amino acids.

We use alkalised cocoa, which has a milder and rounder taste than raw cocoa, so you get chocolate without the bitterness. It tastes like a proper chocolate milkshake, and it works well with cold milk. The protein is made by fermenting yeast instead of farming animals or crops, and it gives you 22.7 g per scoop.

This one is built like a cookie milkshake: sweet, biscuity, and creamy, with a small hint of salted caramel behind it. Mix it with milk, and it drinks like a dessert. With water, it is lighter but still full of flavour. Every scoop has 23.6 g of fermented yeast protein.
