The Recovery Drink that Advanced Sports Science

It is quite unusual in commercial development when a new product is deemed a major breakthrough and at the same time, advances our understanding of science. Endurox R4 created the recovery category and multiple studies conducted using Endurox R4 gave scientists enormous insight on the mechanisms underlying muscle recovery.

Every ingredient in Endurox R4 was specifically added to maximize recovery. It was the first product to show that a 4:1 ratio of carbohydrate to protein could accelerate recovery and raise the training level. Studies have reported a 55% increase in endurance in a subsequent workout 16 hours later and a 14% increase in muscle function 24 hours later.

Compared to a carbohydrate-only recovery beverage, Endurox R4 increases post-exercise protein synthesis or muscle repair, by 400%. What many athletes find surprising is that Endurox R4 actually increases protein synthesis 37% greater than a protein drink. The carb-protein combination activates multiple pathways for turning on protein synthesis, whereas a protein drink primarily activates a single pathway.

The combination of rapid-acting carbohydrates contained in Endurox R4 ensures fast absorption and transport to muscle cell within the 45-minute recovery window. The addition of glutamine to Endurox R4 helps replenish the muscle cell’s number one amino acid and the unique combination of antioxidants neutralizes free radical formation that occur as a natural consequence of exercise and are a major cause of muscle soreness.

To punish myself for a slack-off slump, I decided on a 5 mile 47 lbs weight vest run. New Orleans in July at noon on a cloudless day. Seemed like a good idea at the time. Endurox R4 post heavy workouts is routine at our house. I may not have died, but certainly would have found myself paying for an ambulance ride if not for this recovery drink. Highly recommend to idiots (like me) who push it to the limit.

I have been running for 31 years now and counting! I have run up to 122 miles a week and have gain experiences with nutritional testing of my body. And can say Endurox R4 makes a difference for my running performances to stay strong, consistent, improve my fitness level and recover faster! I would highly recommend you join the Endurox R4 team of flavors!
