What is Pure Nutrition ISO?

Pure Nutrition ISO is a delicious and refreshing hydrating drink made with natural mineral water sourced directly from high-quality mineral wells in Germany. This hydration and recovery drink is naturally rich in essential electrolytes while being very low in calories and sugar, making it the superior choice to typical sports beverages. Pure Nutrition ISO comes in a great-tasting Tropical flavor and is aspartame-free. 

Benefits of Pure Nutrition ISO

ISO is our refreshing hydration beverage made with fresh mineral well water that contains a balanced profile of naturally occurring mineral electrolytes, including calcium, sodium, magnesium, bicarbonate, and chloride. Hydration is a crucial aspect of your athletic performance and overall well-being. Lacking electrolytes and/or water is well-known to impair a myriad of physiological processes, especially muscular contraction. 
By providing an ample amount of both natural mineral water, ISO helps keep you hydrated and replenishes fluid lost through sweating while you’re exercising, which is crucial for sustaining athletic performance, muscle contraction, and healthy cellular function.

Key Benefits of Pure Nutrition ISO:

  • Rich Source of Naturally Occurring Mineral Electrolytes
  • Keeps You Hydrated and Promotes Recovery
  • Supports Optimal Athletic Performance
  • Boosts Muscle Contractile Force
  • Increases Antioxidant Capacity
  • No Aspartame
  • No Fat, Caffeine, or Stimulants
  • Very Low in Calories and Sugar
Electrolytes are chemicals - usually minerals - that become ions (charged molecules) in solution and conduct current throughout the body. The balance of electrolytes in your body is an integral aspect of cellular physiology, especially for athletic performance.  Sweating and urination cause electrolytes to be flushed out of the body, which can hinder performance if they aren’t replenished. This is why drinking ISO before, during, and/or after vigorous exercise is beneficial for athletes, gym-goers, and fitness enthusiasts alike. 

Here’s a brief overview of the electrolytes in ISO and how they impact athletic performance:

Magnesium is one of the most lacking minerals in the modern human diet, yet it’s also one of the most important for efficient muscle contraction, cardiovascular function, neurotransmission, digestion, and healthy fluid balance. 
Calcium is most abundant within bone tissue throughout the body, but it plays many other roles outside of the skeletal system. In fact, calcium is a core electrolyte in the muscle contraction process and is readily stored in the sarcoplasmic reticulum of muscle tissue. The release of calcium ions from the sarcoplasmic reticulum is the initial step in the muscle contraction cycle. In other words, without enough calcium, your muscles can’t contract efficiently, thereby reducing athletic performance.
Sodium is the major positive ion (cation) found in the fluid outside of cells. In conjunction with potassium, sodium regulates the amount of water inside and outside of cells and is essential for proper cell-to-cell signaling. 
Chloride is a major anion electrolyte present all bodily fluids, typically in a greater concentration outside of cells. Chloride plays key roles in nerve impulse transmission, regulating blood pH, and cellular fluid balance. 
Bicarbonate (Hydrogen Carbonate)
Bicarbonate has ubiquitous roles throughout the human body by acting as a buffer and increasing blood pH, thereby promoting alkalinity. In addition, bicarbonate has been shown to increase athletic performance by countering the inhibitory actions of lactate during high-intensity exercise.1

What Makes ISO the Best Sports Drink?

ISO is taking the sports drink category to a new level with natural mineral water that serves as a source of electrolytes in their native state, unlike most hydration formulas that contain synthetic minerals. In addition, ISO contains a mere 17 calories per 750 mL bottle and just under 4 grams of sugar, making it much healthier than sports beverages that contain 40+ grams of sugar per liter and tons of unnecessary calories. Optimal hydration is a crucial component of athletic performance and recovery, try ISO today and experience the Pure Nutrition difference for yourself!
