Popular eatery, wagamama, has joined forces with mindfulness expert Michael Townsend Williams to create a serotonin-boosting juice to help Brits beat the January Blues.

The new, limited edition positive juice, is a tasty blend of pineapple, apple, lime, spinach and cucumber – fruit and vegetables that contain natural feel-good properties as well as vitamins and antioxidants to help boost energy levels. Made fresh to order, the nutritious juice is squeezed, pulped and poured using 100% raw ingredients.
