Best vegan protein bars

The most popular varieties of protein are whey and casein, both of which are dairy products as they come from milk during the cheese-making process. These are not suitable for vegans and so vegan protein bars must be made with plant-based protein sources such as legumes and seeds or pea and algae.¹ It can sometimes be a little challenging for vegans to get sufficient protein in their diets, since a lot of protein sources come from meat, fish or dairy products. Therefore, if you are finding it difficult to get enough protein, it is important that you supplement this - and a protein bar is a great way to do this. These vegan protein balls are high in both protein and fibre and contain less than 160 calories. They are all natural and have a delicious squidgy nut butter centre. Perfect for a sweet protein-packed treat.
