Bread baker Jason’s Sourdough brings its talents to protein bread at 11.8g a slice

Jasons Sourdough Protein Loaf

The functional food space is one of our favorites primarily for its variety and just how creative and unique companies can be. Whether it’s a protein bar with a gooey filling or marshmallow-like body or more uncommon formats like a protein ice cream bar or crunchy pretzels filled with protein, the category is one of the most fun in the realm of health and nutrition. Jason’s Sourdough in the United Kingdom reflects that as it has made its way into the space without that necessarily being its core focus.

Jason’s Sourdough is very obviously a company that specializes in the making of sourdough bread, in fact, it says so right in its catchphrase, Jason’s Sourdough, “an every day obsession”. The baker makes straight white bread, sprouted grain bread, the ciabatta and sourdough hybrid ciabattin, and even bread rolls. Jason’s has landed here at Stack3d because of its innovative Protein Loaf that can conveniently be found at Tesco supermarkets, which also has exclusivity on the protein-packed bread.

The nutrition profile of Jason’s Sourdough Protein Loaf is impressive as it’s high in protein and lower in carbohydrates compared to standard bread. A single 58g slice has 11.8g of protein, 12.9g of carb, 3.7g of fat, and 138 calories, giving you an almost one-to-one protein-to-carb ratio, balancing out to 47g of protein and 51g of carbs in four slices. Jason’s Sourdough makes Protein Loaf with wheat flour and wheat and pea protein for the extra protein, and with the experience it has behind it being a bread and sourdough specialist, we have no doubt that this will taste as good as regular bread.
