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.

I have used EDUROX R4, ACCELERADE and EDUROX EXCEL for more than 10 years. I have been in Law Enforcement for 23 years and this is the first product that has helped me in my profession. I started it to help me prepare for the physical agility required to join a SWAT team and felt amazing results making it so much easier to prepare. I continued to use it for my workout routines and then used to to prepare for the US Border Patrol Academy at age 36. I competed the academy competing with a younger crowd with such ease and felt great. My endurance kept improving and I never suffered a migraine headache throughout the academy which I have always suffered from since I was a child. I continue to use all three products to help me at work with the long and hot walks wearing full gear in the Laredo, TX heat. I am 45 years old right now and feel better than I did when I was younger. I have tried Lemon Lime, Tangy Orange but my favorite is Fruit Punch. I just wish they had this when I was younger.

Love it
I love Endurox R4. Since I am using it my recovery is a piece of cake. Either after a hard track workout or a long run I have no problem waking up the next day. Body is rested and muscle fully recovered.

Mother of a Runner :)
My son started using Endurox R4 this year after every Cross Country / Track & Field practice and he's really seen a difference in the recovery process. I'm so happy his coach recommended this product to us!

Endurox R4 is honestly the best and cleanest recovery drinks out there. I have been using it for years. It still amazing me, no matter how tough of a workout I do it will help me get ready for the next one. If you haven't already tried it do yourself a favor and give it a try.

Marathon Maniac
I am grateful I learned about Endurox to help me reach my goal of doing 6 Marathons in 6 months to celebrate turning 60 from 1-7-18 to 6-3-18. I injured my left knee during the 1st January marathon and was only 6 months post surgery on my right knee, so I didn’t know if I’d make it through my 6 marathon challenge. Then I learned about Endurox at a running retreat. I used Endurox for recovery and I not only made it through the last 4 marathons without injury, but I recovered really quickly after each one. In fact, I didn’t have any need to recover I could just jump right into the next one the week after. They were all a week apart. I not only survived the Brutal Boston Marathon on 4-16-18, 1 week after the Paris Marathon on 4-8-18, but I even BQ’d and got 3rd place in my division at Mountains2Beach Marathon on 5-27-18! I’m now a huge fan of Endurox and I tell all my running friends about it. I also discovered Accelerade, Accel Gel, and 2nd Surge. All helped me reach my goals. My next marathon is NY, my 3rd US Marathon Majors in 13 months, then I’ll hopefully complete another 6 in 6 months in 2019 on my way to 70 marathons by 70. You can bet this Marathon Maniac will be using Endurox, Accelerade, Accel Gel, and 2nd Surge. Hugs! Your fan, Karen

I've been using Endurox R4 for years in ultra long distance road cycling, I used it as a triathlete and will always use it as long as I'm active. I've only had the lemon lime but wouldn't mind trying the chocolate, but I won't purchase the chocolate in case I don't like it. But a trial pack sure would be nice. :-)

Been using various recovery nutrition supplements for years but decided to try Endurox R4 (with free shipping through the endurance club!) and it's the best tasting/working product on the market! Thank you for the free stuff PacificHealth!
