Karítas María Lárusdóttir, a business student, personal trainer and teacher at World Class, started adding Feel Iceland collagen to her oatmeal in the mornings and has noticed a huge difference. "The benefits are really amazing because I used to run for a long time in the mornings, but now there is no more stiffness, my joints are soft and flexible. I also recover much faster after workouts. I teach spinning and my thighs were often sore after intense cycling sessions, but now I no longer feel that tired and can do a hard workout the next day as if nothing happened," says Karítas María.
