Saltstick started over 15 years ago in Southern California after Dr Jonathan Toker wanted to better meet the electrolyte needs of elite athletes during training and competitions.

Saltstick Electrolytes help restore lost electrolytes due to perspiration which is needed to prevent muscle cramping and minimise heat stress. Produced in the USA in cGMP (current Good Manufacturing Practices) facilities, ensures Saltstick products are certified free of any banned substances and are independently tested.  


SaltStick Founder

Jonathan Tocker, PhD is an elite-level trail runner and triathlete from Canada who has competed in triathlons and races for over 5 years.

In 2001, he earned a PhD in Organic Chemistry from The Scripps Research Institute and worked in the biotech industry for 5 years, before founding Toker Engineering LLC. After creating Saltstick Caps which were developed as a study of scientific literature on electrolyte loss in sweat, highly bioavailable ingredients, and field testing, Saltstick was born.

In 2007, he left his job at the Cardinal Health and Amgen, to focus on Saltstick full-time and Saltstick Caps have since become the accepted standard for electrolyte replacement capsules. 


Saltstick Vitassium is an electrolyte capsule specifically designed as a medical food to provide sodium and potassium for the clinical dietary management of people with dysautonomia and other chronic medical conditions. Dysautonomia is any disorder of the autonomic nervous system which regulates functions we don't consciously control, such as heart rate, blood pressure, sweating and body temperature.

SaltStick Vitassium can help the symptoms of conditions such as:

  • Postural Orthostatic Tachycardia Syndrome (POTS) 
  • Ehler Danlos Syndrome (EDS)
  • Cystic Fibrosis (CF)
  • Vasovagal Syncope
SaltStick Vitassium

The increased plasma volume in Vitassium has been shown to be beneficial for those with such disorders. Vitassium helps maintain electrolyte levels, supports healthy blood pressure, reduces fatigue, supports cognitive function, and reduces dizziness due to low blood pressure.

Vitassium is non-GMO, gluten free, preservative free, allergen free, starch free and contains no caffeine. The small tasteless capsules are easy on the stomach with its four ingredients; sodium chloride, potassium citrate, stearic acid, and vegetable capsule.

SaltStick CapsCAPS

During 30-60 minutes of activity, the average athlete loses around 11oz of sweat which contains key electrolytes. Saltstick Caps are the best electrolyte replacements on the market due to their close match to the natural electrolytes produced by the body. By using sodium, potassium, magnesium and calcium, and closely matching them to their known quantities, Saltstick Caps have since become the accepted standard for electrolyte replacement capsules.  

SaltStick ChewCHEWS

Saltstick Fastchews comes in packs of 10 or 60 capsules in 4 fruity flavours of Perfectly Peach, Tart Orange, Seedless Watermelon, and Zesty Lemon and Lime. Fastchews are a chewable electrolyte replacement that prevents muscle cramping and minimises heat stress caused by the lost electrolytes from perspiration.  

SaltStick VitassiumVITASSIUM

Saltstick Vitassium is a medical food specifically designed for people with autonomic dysfunction disorders. These disorders deregulate functions such as heart rate, blood pressure, sweating and body temperature. Vitassium helps these negative effects by maintaining electrolyte levels, supporting healthy blood pressure and cognitive function, and reducing fatigue and dizziness caused by low blood pressure.
