Endurance MultiV vitamins are designed to meet the unique requirements of endurance athletes. Features include clinically effective doses of iron, vitamin K2, vitamin D, and unparalleled antioxidant protection. In addition, Endurance MultiV also contains special digestive enzymes that improve carbohydrate utilization and time to exhaustion, Green Tea for improved endurance capacity and fat utilization, and Zinc for enhanced muscle recovery. 

 Now With Vitamin D and K2
 High-Potency Multivitamin
 Designed Especially for Endurance Athletes
 Unparalleled Antioxidant Protection

THE HIGHEST ELECTROLYTE CONTENT AVAILABLE
 Clinical research shows endurance athletes require much higher levels of electrolytes than most sports drinks provide to prevent cramping and dehydration (4). The new EFS drinks now contains over 1,160mg of all 5 electrolytes per serving, more than any electrolyte drink on the market.

THE LATEST AMINO ACID TECHNOLOGY
 The Amino Acids in the EFS 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.

 SUPERIOR CALCIUM BIOAVALIBILITY
 The new EFS formulas utilize two unique sources of calcium and magnesium. DiCalcium malate and Dimagnesium malate have superior bioavailability compared to other mineral sources. In a bioavailability study, absorption rates were between 20% and 100% higher using DiCalcium and DiMagnesium malates (1).

 NOW WITH MALIC ACID
 The new EFS drink contains 700mg of Malic Acid, which was not found in the previous formula. Malic acid stimulates oxygen consumption by increasing mitochondrial uptake, improving mitochondrial respiration and increasing energy production. Malic acid is essential in the formation of ATP, the body's energy source. Malic acid allows the body to make ATP more efficiently, even under low oxygen, or hypoxic conditions.
