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.

Prior to using Endurox R4 I had used several other recovery drinks. I didn't feel that I was getting the recovery results I felt I needed and talked with my coach about it and he recommended that I try Endurox R4. After using it. I found that I was recovering quicker and was ready to continue training at a new level. Endurox R4 is always in my bag for my after run recovery drink. I began using Endurox R4 in 2016 and it still works, so I keep using it.

I have been an Endurox drinker for at least 10 years. Endurox makes my muscle recovery faster, keeps muscle soreness at a minimum and helps me avoid crashing when I am done with a long run. I have used it during yard work on hot days and as an afternoon energy boost just because. I like it ice cold. I've had all the flavors but chocolate and like them all. I recommend it to all my fellow runners, a few have become converts.

I have used this product for over 10 years if not longer. I use it after long cycling work outs and after strength training. It is one of the few products that the taste and it's purpose of providing what is needed after a hard work out are achieved.
