First Endurance EFS Hydration 960g

Q: How is EFS different than EFS-PRO?

 A: Though EFS is itself a step above the competition, EFS-PRO supports the most demanding efforts in the most extreme conditions by providing 2x more carbs and more electrolytes/serving. 

Q: Are there other benefits to drinking EFS or EFS-PRO, besides for training and racing?

A: Absolutely. EFS and EFS-PRO can be used to top off glycogen and electrolyte levels before an event or race.

 Q: Do EFS or EFS-PRO have any artificial flavors or colors?

A: No, but it tastes so good you’d be forgiven for thinking we were cheating.

 Q: Do I need to take a full serving of EFS or EFS-PRO to get a benefit? 

A: No. A higher concentration increases calories and electrolytes. While our recommended serving concentration is designed to maximize theanine’s effects in a steady dose, ingesting reduced amounts will still produce a proportionally scaled effect in terms of promoting calm focus. In other words, if you are a smaller person and normally consume a somewhat reduced amount, you will still get the same benefits.

 Q: Do EFS or EFS-PRO have any stimulants in it?

No. In fact, it does the opposite, calming you down and maintaining a cool, collected approach to whatever you’re doing, whether that’s racing, training, or resting up the night before an event.

 Q: Can I use EFS and EFS-PRO with caffeine?

Yes. There are no counter-effects from caffeine consumption that you’ve established through your daily caffeine habit—err, intake. Keep drinking tea or coffee as usual. 

 Q: How much EFS should I use during my training and racing?

 A: Consume one serving
30 minutes before exercise. Use as needed during exercise.Additional calories and electrolytes can be added with Liquid Shots.

 Q: How should I mix EFS?

A: USE DIRECTIONS
SMALL SERVING: Mix 1 scoop with 21-22oz of water

LARGE SERVING: Mix 1 ¼ scoop with 24-26oz of water

Q: Is EFS vegan friendly?
A: Yes.

Q: Is EFS gluten-free?
A: Yes.

Q: What's the glucose:frucose ratio in the formula?

A: The glucose: fructose ratio in the EFS formula is  6:1 Glc:Fru.

Q: Is there any way to get too much Theanine from EFS?

A: Only if you macro-dose (200mg or more in a single or repeated shot). Even if theanine is administered in a single macro-dose, the effect is just a too-calm calm that fades as the theanine leaves your body—Nothing serious or harmful. Learn more about dosing and uptake. That’s because theanine is water-soluble, it metabolizes fast and doesn’t accumulate . Once ingested, it’s half gone after 60-90 minutes, and it’s gone completely in 24 hours.  

 Q: Does EFS or EFS-PRO help me hydrate better than water?

A: We won’t name them, but there’s a growing list of competitors in the sports hydration game making the claim that their product hydrates better or faster than water alone. This is a so-what claim predicated on evidence that not only doesn’t apply to endurance athletics, but actually hampers performance during long-term endurance events. For their rationale and claims support these companies cite WHO and other medical guidelines for treating serious dehydration in disease and severe exposure conditions, not the sports nutrition guidelines for healthy athletes in endurance competitions. Also important is the need for more fuel, and these drinks fall short in the fuel department.

 Q: I’ve heard that there are benefits to having protein during exercise. Why doesn’t EFS contain protein?

A: EFS contains 2g free form amino acids per serving which is the equivalent in BCAA and glutamine profile to 9g whey protein. Protein naturally contains BCAAs and glutamine.

Clinical evidence supporting the use of BCAAs and glutamine during exercise dates back to 1991. These clinical studies clearly indicate supplementing with as little as 1g free form amino acids improved performance, reduced post-exercise muscle damage, improved muscle glycogen resynthesis, reduced central fatigue and improved rate of perceived exertion. These are the same claims made by the most recent protein study and clearly support a mechanism for improved performance.

In addition to the clinical support, other factors lead to a decision to use these free form amino acids over complete proteins.

Proteins are more difficult to digest than amino acids during exercise, they don’t taste very good during exercise, and they can reduce the glycemic index of a drink, further reducing its ability to be quickly absorbed. There is considerably more evidence supporting free form amino acids than complete protein

 Q: Are EFS and EFS-PRO safe for kids?

Yes. Just make sure they pay it back during their turns at the front. 

 Q: I am prone to cramping during longer training and racing. Will EFS help me with cramping and dehydration problems?

A: Yes, cramping stems from electrolyte imbalance, electrolyte depletion and/or dehydration. EFS provides a clinically-effective dose (of all 5 key electrolytes) to prevent cramping and dehydration. The combination of all five electrolytes delivers a potent 1160mg per serving, helping to prevent cramping. The 300mg sodium per serving also aids in maximum fluid absorption so you stay hydrated throughout your training and racing. Supplementing with additional salt tabs, electrolyte tabs, or salty snacks is not necessary with EFS.
