Why athletes need electrolytes

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

How SaltStick can help support your performance on the court

SaltStick products are designed to help to reduce muscle cramping and heat stress, boost stamina, and maintain electrolyte levels by replacing five electrolytes lost through sweat: sodium, potassium, magnesium, calcium and chloride.

The average person’s sweat contains about 1,000 mg sodium/liter, but a typical sports drink contains 440 mg sodium/liter. If, during the course of activity, you consume 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. Many sports drinks also do not include other key electrolytes, which could lead to further cramping and muscle issues.

SaltStick helps athletes maintain peak performance by replacing a full spectrum of electrolytes lost through sweat, in a form and quantity the body can absorb.

How to implement SaltStick into your training

Each person’s nutritional needs are unique, and it’s best to develop a plan that offers the right balance for you. As a general guideline, athletes may benefit from taking:

  • 1x SaltStick capsule, OR
  • 2-4x SaltStick Fastchews, OR
  • 1x 5mL serving of SaltStick Elixaltyte

every 30-60 minutes during activity OR:

  • 1x serving of SaltStick DrinkMix combined with 16-20 oz. (~475-600 mL) of water

every 60-90 minutes during activity.

In hot conditions, extreme humidity, or for larger athletes, a greater quantity may be needed to maintain optimal electrolyte levels.
