EFS drinks provide everything you need to maximize endurance and performance during exercise so you can train and race knowing you don’t have to worry about cramping or dehydration.

✓ Premium Hydration Drink Mix
✓ Prevents Cramping & Dehydration
✓ Improves Performance During Exercise



EFS drinks provide an ideal blend of simple and complex carbohydrates, amino acids, antioxidants and electrolytes you require to fuel working muscles and increase endurance during exercise.

You’ll notice the difference right away too. With the latest amino acid technology, superior mineral bioavailability and the addition of Malic Acid, EFS drinks refuel working muscles faster than ever before.

They taste great, not chalky or overpoweringly sweet. And with the highest electrolyte content available (1160mg of all 5 electrolytes/serving), there’s no need to carry those extra electrolyte pills or add anything else.

Plus, EFS 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.


Consuming carbohydrates during prolonged exercise enhances performance by supplying energy for muscles to use when glycogen stores begin to drop.

EFS products have been specifically formulated to deliver the ideal blend of complex carbohydrates, glucose (dextrose) and sucrose for energy. Clinical research shows a combination of carbohydrates is better than a single source for the absorption and utilization of blood glucose (Guezennec, C.Y, et.al.).  EFS products also provide three different high-glycemic sources of carbohydrates for immediate energy and easy digestion during long and intense workouts.

The low osmolality of the EFS energy drink and ideal 7% carbohydrate solution provides superior fluid absorption. Clinical research shows that energy drinks mixed within 6-8% offer the optimal absorption of both carbohydrates and fluid for endurance racing and training (Shi, K et al.). The biochemical structure of the carbohydrate, the absorption process, the size of the food particle, the degree of processing, the contents and timing of the previous meal, and the co-ingestion of fat, fiber, or protein affect the absorption of a carbohydrate as well as its glycemic index (GI).


The EFS drink formula uses two unique patented sources of calcium and magnesium as amino acid malates.

DiCalcium malate and DiMagnesium malate have superior bioavailability over other calcium sources. DiCalcium malate in a bioavailability study proved to be absorbed significantly better and remained elevated from time 0 to 12 hours, representing a more absorbable form for a longer period. Absorption rates were between 20% and 100% higher using DiCalcium and DiMagnesium Malate.

Furthermore, these superior minerals also offer a buffering of stomach acids. DiCalcium malate and DiMagnesium Malate lower stomach acids significantly, helping to reduce the unwanted gastric distress that can be associated with other minerals.


The ability to rapidly replenish carbohydrates after training, and the ability to consume and convert ingested carbohydrates into a usable form of carbohydrate, is important in allowing you to train and compete at your best. Ingestion of the wrong carbohydrates at the wrong time, or ingesting too little carbohydrate can impair performance both in the short term and long term.

Consuming a slowly digested carbohydrate during times where the body is at or above threshold can lead to disaster. During times where you exercise or race at and above your threshold, your blood circulation is focused on the working muscles and away from the stomach. This makes digestion of foods difficult.

In fact, consuming a slowly absorbed sugar during these times will slow gastric emptying (the emptying of fluids and foods from the stomach to the blood stream) and in essence block fluids from being absorbed. This can actually cause dehydration.


Endurance athletes have different fluid and electrolyte needs, particularly during longer and higher intensity training sessions and competition. The increased loss of sweat translates into an increased loss of electrolytes, and, as previously mentioned, sodium is one of the important electrolytes that must be replaced during exercise to prevent dehydration and hyponatremia.

The composition of standard sport drinks may not provide an adequate amount of electrolytes during activity lasting longer than two hours. Most standard sports drinks contain 50- 110 mg (200-460 mg/liter) of sodium per 8 oz.

Because we are limited on the amount of fluid the body can absorb by the intestines, it may be important to consume a higher amount of sodium during exercise to minimize fluid loss. The body can tolerate a higher sodium intake (closer to the amount lost in sweat) and it does not appear to negatively affect carbohydrate absorption.
