A high protein pizza, launched into retail just a few months ago and created for the health conscious consumer, is now being stocked in 427 outlets across the UK.

The pizza, developed by online health and fitness retailer Musclefood. com, has seen a big increase in the number of stockists selling the healthy alternative to the fast food favourite.

Gyms, health food chains, and supplement stores have all come on board since it was launched to trade in February and the retailer is in talks with leading supermarket Sainsbury’s.

The pizza also launched in 155 Super Valu and Centra stores in Ireland earlier this year and since being stocked has recorded the best ever sales for a new frozen pizza brand.

Each pizza contains around 600 calories, the same amount of protein as three chicken breasts and five times less carbohydrates than the average takeaway pizza. Fat content is much lower too with each slice containing 2.4g of fat compared to 15.3g in some takeaway alternatives.

Each pizza has an authentic stone baked base but the traditional bread flour has been replaced by pea protein powder, which increases the protein content. Each pizza is also gluten free.

This is the first time the pizza has been made available to high street shoppers. Previously pizza lovers have only been able to buy the healthier alternative from the Musclefood.com website.
