We typically associate amino acids with rebuilding muscles and post-training recovery, so why are amino acids important for immune function? Because your immune system operates differently from muscles, nerves, and other organs; it uses amino acids as energy, even preferring them to glucose and fats.
The immune system’s major amino acid fuels are glutamine and the branched-chain amino acids leucine, isoleucine, and valine, which we’ll just lump together as BCAAs for this blog. Because of their known importance for immune cells, research has focused on these amino acids and immune function in long-term, strenuous exercise.

Rally Cycling’s talented all-rounder, Kyle Murphy, has been quietly putting together another impressive year with strong showings throughout the season. He finally clawed his way to the top step on stages two of the Volta a Portugal.
Calling that race “hot” is an understatement, so we asked him about his approach to hydration and fueling, as well as his general impressions of how the day went. His initial response was, simply, “Tough race!” However, he did elaborate on fueling, hydration, tactics, and the importance of keeping a cool head when the race is figuratively (and, in this case, literally) heating up.

We have all heard the saying, “nutrition is the fourth leg of a triathlon.” And no doubt we have all heard horror stories and seen (and even smelled!) the evidence of when someone gets their nutrition plan for long-course triathlon racing very wrong.
Last month, Joey Rosskopf of Rally Cycling won the US national crit championship. His stablemate, Kyle Murphy, finished third after a day spent animating the race in a two-man break that depleted the strength of EF Education-Nippo, who were easily co-favorites with, of course, the dominant L39ION of Los Angeles.
Training and racing in cold weather is entirely different than training and racing on hot days. Strange things happen in hot conditions; some athletes thrive while others fall apart. Your nutrition program has a lot to do with how well you handle extreme conditions. Dehydration, cramping, and GI distress can wreak havoc on your performance, so it’s important to pay attention to your sweat rate.
After months of research-driven tinkering, testing, and trial, we’ve updated the formulas for EFS and EFS-PRO hydration mixes. Given the technical–and, frankly, revolutionary–nature of both formulas, we compiled a list of changes to quickly highlight and explain the differences and confirm what’s stayed the same.
Cyclic Cluster Dextrin is turning out to be a premier form of carbohydrates for extending exercise performance, probably by not having the drawbacks of other carbohydrate sources. CCD’s unique molecular structure gives it the ability to not have gastric side effects and to help prevent central fatigue (feeding the brain) that other carbohydrates cannot do as well. CCD – a better mousetrap for delivering carbs during endurance exercise.
Q: A lot of pros are using ketone esters. Do they really work?
A: Not as well as one would think. Here's why.
