Advanced Nutrition for the Endurance Edge

EO2 Edge is not your typical "sport-ade" carbohydrate and electrolyte drink that addresses only a small fraction of the unique performance needs of endurance athletes. This advanced stimulant free formula helps athletes overcome the unique mental and physical limitations they experience during extreme endurance training and competitions.*

For example, during a marathon, the metabolism in an endurance athlete's body can increase to 2000% above normal, and oxygen utilization may elevate by up to 1500%! Additionally, fluid loss, electrolyte depletion & free radical damage are a constant threat to peak performance.*

EO2 Edge was formulated with scientifically validated ingredients to address and help overcome these unique endurance challenges and more. EO2 Edge supports improved oxygen transport and utilization, boosts ATP energy, offers nitric oxide boosting exercise extenders (NBEE), provides key electrolytes, and delivers a Tri-Source energy blend for sustained energy and endurance.*

EO2 Edge is the ideal choice for pre, intra, and post-performance fueling to meet the demands of high-intensity, long duration bouts of exercise and competition.*

The incredible part is that EO2 Edge is 100% stimulant free. In order to fully appreciate the power of this stimulant free endurance formula, we will need to take a deeper dive into the science behind EO2 Edge.

The Science Behind EO2 Edge

It's More Than Consuming Carbohydrates

The body's metabolic changes during a marathon have been documented. Exercise represents one the highest levels of extreme stresses to which the body can be exposed. For example, in a person who has an extremely high fever approaching the level of lethality, the body metabolism increases to approximately 100% above normal; by comparison, the metabolism of the body during a marathon race increases to 2000% above normal.*1-3

Here's the key; performance of strenuous exercise is limited by the amount of stored carbohydrates in the body.*4-5

Now, don't make the mistake of thinking the solution is all too easy. In fact, this is where many "endurance products" completely miss the mark. Simply providing a single source of carbohydrate (as some commonly do) does not yield optimal energy availability.*

The Secret of Multi-Source Performance Fuel

MRI® EO2 Edge utilizes a new approach to providing carbohydrates in sports supplements that overcomes the usual intestinal absorption limits. The result; higher rates of carbohydrate consumed during exercise can become available as a source of muscle fuel. EO2 Edge features the Enduro-Tri Energy Complex - an expertly crafted synergy of maltodextrin, a source of sustained glucose fuel, fructose, and medium chain triglycerides (MCTs).*

Recent studies have suggested that larger intakes, in particular of glucose:fructose mixtures, can result in greater improvements in performance.7-10 The ingestion of solutions containing carbohydrates with different intestinal transport mechanisms (e.g., fructose and glucose) produce greater carbohydrate and water absorption compared with single-carbohydrate solutions.*

Here are the basics of how this works. Glucose is absorbed in the intestine by the sodium dependent glucose transporter SGLT1 (8)11 whereas fructose is absorbed by the intestinal transporter GLUT 5 (33)7,13,14. Studies confirm that multiple transport carbohydrates resulted in higher (up to 75%) oxidation rates than carbohydrates that use the SGLT1 transporter only.8,15

As an added source of highly efficient endurance fuel, EO2 Edge features a fully loaded dose of Medium Chain Triglycerides (MCTs) - a quick burning lipid that provides 200% more energy per gram than carbohydrates.*

MCTs are a true anomaly among lipids as they don't require going through the "typical" digestive process. MCTs are emptied rapidly from the stomach and are immediately absorbed and hydrolyzed by the small intestine.16 MCTs are efficiently absorbed and don't require the intestinal lymphatic system or bile salts for absorption.17,18 Thus, MCTs are a swift source of energy directly absorbed in the blood stream. In fact, the velocity by which MCTs are absorbed in the intestine is similar to the one of glucose.*

Supplying Oxygen: The "Elixir" of Endurance Capacity

Unquestionably, oxygen availability is a critical factor in driving peak endurance capacity. In fact, exercise increases O2 consumption up to 15 fold (1500%). Therefore a truly complete, fully effective endurance product must address O2 availability. Of course, this is exactly what the MRI researchers set out to do and achieved.*

First, key ingredients in EO2 Edge help to support optimal red blood cell (RBC) formation. This factor is no small matter; RBCs carry oxygen to working muscles.*

Key ingredients in EO2 Edge "go to the source" to help optimize RBC production and their flexibility during exercise. Some of the specific "key ingredients" are Folate, Vitamin B6, Vitamin B12 and the mineral Zinc. Vitamin B6 plays a major role in making proteins and the formation of hemoglobin. Folate and Vitamin B12 help build the red blood cells that carry oxygen to working muscles. This is 100% natural RBC support.*

Once red blood cells are formed, zinc (Zn) supports their full functionality. A double-blind, cross-over study of ten healthy male athletes (age: 26+/-1.3 yr; weight 67.9+/-2.24 kg; height 177+/-3 cm) with low blood levels of zinc found that 20mg per day of zinc for 7 days improved the flexibility of the red blood cells during exercise, decreased the exercise induced increase in blood viscosity, and significantly decreased the rating of perceived exertion after 20 minutes of exercise compared to placebo (P=.0008). These findings indicate that Zn supplementation in athletes with low blood Zn levels may help benefit blood flow to the muscles and improve exercise tolerance.19*

In simple terms, EO2 Edge features key ingredient technologies that support the production and viability of oxygen-carrying red blood cells to promote efficient oxygen transport and uptake into working muscles.*

More Energy Machines

Adenosine 5'-triphosphate, otherwise known as ATP, has been called the body's "cellular currency" with the important function of transferring energy to every cell of the human body.20 Simply put; ATP molecules are the "energy machines" that drive muscle function.*

However, the turnover (usage) of ATP is extremely high. For example, even a human at rest consumes one half of his/her weight of ATP daily24 For endurance athletes, the demands are much greater; ATP energy needs can skyrocket to 1,000-fold in just a few seconds.*

Here's the problem; skeletal muscle concentrations of ATP are relatively limited, thus ATP must be continually resynthesized21 at a rate complementary to ATP demand.22,23 This requires the presence of specific nutrients and cofactors at the source of ATP production, the mitochondria of cells.*

The synthesis of ATP by intact respiring (working) mitochondria requires the presence of oxygen, magnesium, substrate (glucose, lipids), ADP and inorganic phosphate.24,25 Additionally, riboflavin and niacin, two of the B Vitamins, are directly involved in ATP synthesis.*

EO2 Edge provides essential nutrients for ATP production (i.e., magnesium, phosphate, niacin and riboflavin), all of which are intricately involved as necessary cofactors for helping the body produce ATP. Consuming EO2 Edge before and during an endurance event helps to support optimal ATP production, when it's needed the most.*

The Nitric Oxide Connection

EO2 Edge features nitric oxide boosting exercise extenders (NBEE) to support optimal endurance performance. This represents a substantial shift in endurance supplement technology and how nitric oxide molecules are leveraged.*

Traditionally, nitric oxide (NO) boosting supplements have been targeted for bodybuilders seeking enhanced vasodilation. For them, vasodilation means greater muscle "pumps" and vascularity. While vasodilation is beneficial for strength and endurance athletes, there is much more to the nitric oxide story than vasodilation alone.*

According to authoritative sources, changes in NO production can affect vasodilation and blood pressure and interventions that influence NO bioavailability can also alter the O2 cost of exercise in humans.26-28Translation; not only does nitric oxide support optimal, nutrient-surging blood flow, it may also positively impact oxygen utilization.*

Furthermore, muscle metabolism appears to be NO-sensitive at several sites, including glucose uptake, cellular respiration and creatine kinase activity.30 This supports endurance performance on a multitude of fronts. First, glucose uptake is the transfer of this rich energy source from the blood into working muscles. Second, cellular respiration is the process that yields ATP in the mitochondria of cells. Third, creatine kinase is a prime component in the chain of events that drives muscle contractions.*

Cellular Hydration Through Electrolyte Infusion

The power of electrolyte replenishment cannot be overstated. Authoritative sources have documented the essential electrolytes in human nutrition (i.e., sodium, potassium, chloride, magnesium, and phosphorus) and their roles in fluid balance and muscle and neurological function. A deficiency in any of the electrolytes and other key compounds can impose a dramatically negative impact on performance. Specifically, a deficiency of Vitamins B1, B5, and B6 can cause muscle cramping and sodium, potassium, and magnesium all play a key role in reducing the potential for muscle cramps.29*

EO2 Edge is packed with scientifically validated levels of sodium, potassium, chloride, magnesium and B-Vitamins for a truly complete endurance formulation.*

Sodium is a critical electrolyte, particularly for athletes with high sweat losses.30,31 Many endurance athletes will require much more than the UL for sodium (2.3 g·d-1) and chloride (3.6 g d-1). However, a recent study found that 13 percent of Boston marathon runners studied had a serious imbalance of fluid and electrolytes.37*

Potassium is important for fluid and electrolyte balance, nerve transmission, and active transport mechanisms. During intense exercise, plasma potassium concentrations tend to decline to a lesser degree than sodium. Potassium is the major ion of the intracellular fluid but sweat potassium losses are small relative to total body stores. Nevertheless, researchers have found that inclusion of potassium in beverages consumed after sweat loss may aid rehydration by enhancing the retention of water in the intracellular space, otherwise known as cell volumization.33*

According to the National Academies of Science, chloride "is essential in maintaining fluid and electrolyte balance."34 It is involved in body water balance and acid base balance.*

Magnesium is essential for normal muscle contraction and relaxation, nerve conduction, protein synthesis, and in many biochemical reactions related to energy production.35 Magnesium deficiency can result in muscle cramping,36-37 which can put an athlete at risk for muscle injury.*
