Q: How is EFS different than EFS-PRO?
A: Compared to EFS, EFS-PRO has a more premium ingredients list, delivers more carbs and electrolytes, and includes PharmaGABA® for added mental toughness support. Though EFS is itself a step above the competition, EFS-PRO supports the most demanding efforts in the most extreme conditions by providing even more fuel and cramp prevention while doubling down on First Endurance’s revolutionary approach to supporting your brain like it’s a key muscle for endurance athletics.
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 electrolytes and help you calm down so you can get a good night’s sleep the night before (or two nights before) an event or race. When you’ve invested an entire season’s prep in peaking for a specific day, the calming effects of EFS or EFS-PRO can help ensure restless nights leading up to that day don’t undercut your form.
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. The calming effects of EFS and EFS-PRO affect you according to the baseline for caffeine consumption that you’ve established through your daily caffeine habit—err, intake. Keep drinking tea or coffee as usual.
Q: Why doesn’t EFS-PRO contain Vitamin C?
A: EFS-PRO doesn’t contain Vitamin C because the latest research shows that Vitamin C can have a negative effect on endurance and performance when consumed during exercise. Click here for more info.
Q: What electrolyte can we find in the new EFS-PRO?
A: There is 500mg of sodium per serving in the new EFS-PRO drink (EFS has 300mg). This represents the highest sodium content in any electrolyte drink on the market. The EFS-PRO formula now offers over 1,500mg of electrolytes coming from all 5 electrolytes, per serving.
Furthermore, these superior minerals also offer a buffering of stomach acids. DiCalcium and DiMagnesium malate lower stomach acids significantly helping to reduce the unwanted gastric distress that can be associated with other minerals.
Q: Are there any changes to the amino acids?
A: The amino acids in the EFS-PRO drinks are AjiPure amino acids, the purest, most- bioavailable source of free-form amino acids available. AjiPure amino acids have purity levels of 99%-100%. This results in faster and more complete absorption.
Q: What is the osmolality of the EFS-PRO drink mix?
A: EFS-PRO has an osmolality around 250 when mixed at full concentration (32 grams in 12 ounces of water).
Q: How should I mix EFS-PRO?
A: USE DIRECTIONS
SMALL BOTTLE: Mix 3 scoops with 21-22oz water
LARGE BOTTLE: Mix 4 scoops with 24-26oz water
BEFORE: Consume 1 bottle 30 minutes before exercise.
DURING: Alternate 1 serving of EFS-PRO and 1 bottle of water every 30 minutes.
TIP: For additional calories and electrolytes, double the concentration or supplement with Liquid Shot.
