Were pretty excited about our high protein 100% plant-based choccy milk. Heres why you should be too.. Soy is an amazing source of plant protein, containing all nine essential amino acids. We only use responsibly sourced soy beans to create a super smooth taste. It's low in sugar and highly nutritious so you can keep going, and keep living life to the fullest. Its also delicious just saying. Alpro. Good for brekkie, good for you!
