Mark Innocenti

Marathon 2:27:19 and ultrarunner

"Protein Rebel is simply the best sports recovery nutrition brand out there right now! With a range of natural products to choose from, they have you covered. I particularly like their Run Easy Collagen which helps my joints and their Magnesium powder helps me to sleep, particularly after an intensive session."

Alex Bance

Ultramarathon runner

"I’ve got another 5 ultramarathons to do this year. Without these products I wouldn’t be doing them. Nothing has helped keep my Achilles in check more than your collagen/magnesium combo."

"I've taken magnesium supplements in the past to aid quality of sleep and in turn recovery. These have always been in capsule form. Power Up is a far more enjoyable method. Mix a spoon into a glass of water an hour or so before bed for a refreshing drink with a hint of citrus and the best night's sleep!"

“Run Easy has changed my life! I have struggled with joint and muscle pain since being diagnosed with ME, it was debilitating. Run Easy has given me a new lease of life! My pain levels are manageable, I have managed to start walking again, with a plan to get back into hiking! My skin has also never been clearer, and with an upcoming wedding, I’m very grateful to Protein Rebel!”
