SALT SCIENCE

upgrade your performance

When it comes to athletic performance, electrolytes can be the difference between finishing as a champ, or struggling with fatigue, cramping and nausea. These small but mighty elements—which include sodium, potassium, calcium, magnesium and chloride—play a pivotal role in muscle contraction, blood pressure, hydration and other crucial functions.

When we sweat, we lose electrolytes. If we do not take steps to replace these electrolytes during exercise, eventually our performance will decline. Read more about salt, sweat and performance.

Are Sports Drinks Enough?

The average person’s sweat contains about 1,000 mg sodium/liter, but a typical sports drink contains 440 mg sodium/liter. Any more and the drink would probably taste like sea water. 

Simple math illustrates that if, during the course of training, you ingest nothing but sports drinks (or worse, water), you could become hyponatremic at some point. Hyponatremia is a medical condition marked by low blood sodium levels, which can lead to nausea, fatigue, cramping, vomiting, weakness, sleepiness, and in rare severe cases, loss of consciousness.1

Many sports drinks also do not include other key electrolytes, which could lead to further cramping and muscle issues. 

Nutrient Precision

Each person’s nutritional needs are unique, and it’s best to develop a plan that offers the right balance for you. In general, the longer the event, the more important it is to precisely tailor nutrition2, including the timing and volume of electrolyte intake. Performance declines often take place in the latter half of a race, after electrolyte stores have been depleted.3

SaltStick Competitive Advantage

SaltStick helps athletes maintain performance by replacing a full spectrum of electrolytes lost through sweat, and in a form and quantity the body can absorb. An independent 2015 study demonstrated that triathletes who relied on SaltStick to replace electrolytes lost through sweat performed significantly better in a medium-distance triathlon than those who did not. See how SaltStick products compare.
