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.

Good recovery
I do feel like this helps me after a tough workout. And I do feel a little stronger the next day to work out. The flavor is good too. I like it.

Over the 40+ years I have been running and biking I have tried them all. R4 is the only product I can definitely say works. If I go a day without using it after a workout, I will feel it for the next couple of days. Wishing for a return to Vanilla.

I usually get the chocolate flavored R4. It is the drink I look forward to after a hard workout. What better product has the carbs/protein that you need for recovery. The fruit punch flavor is a nice change when you want something refreshing.

Great for workout recovery
This stuff works! I was super fluffy decided to do cross fit. For the love of gawd I couldn't get off a chair/toilet due to leg pain! Friend told me about this magical powder. Changed my life! Not only could I go to class day after day, but I could walk without looking like a drunk wildabeast!! Now I use this post hike, post race, post exercising. Love it!!
