The caps are spot on. I often suffer badly from cramps and these have put an end to that. During Edinburgh marathon, I had threats of cramp at 32k so immediately too 2 extra UltraCaps and the issues never came back. I'm convinced these things saved my race.
Used these a few months now, can’t remember what cramp is
Started using highland fuel and nutrition over the last few months, great source of energy on the longs runs, but for me the ultra cap sodium capsules have been an absolute game changer in stopping cramping issues on longer efforts. Always carry these with me now! Great work team!
Used these during last ultra of devil of the highlands, weather reaching above 20 degrees, zero cramping sticking to strategy using this product
Class
UltraCaps - 300mg Sodium
UltraCaps are a no-nonsense electrolyte capsule designed for endurance athletes who want precise control over sodium intake during long training sessions and races.
Each capsule provides 300mg of sodium, supported by potassium and magnesium, to help maintain electrolyte balance when sweat rates are high and conditions are demanding. The formulation uses buffered sodium sources to improve tolerance and make regular intake easier over long durations.
UltraCaps are designed to be used alongside your fuel, allowing you to adjust electrolytes independently based on heat, effort, and individual sweat rate, without overloading drinks or relying on overly sweet mixes.
Ideal for
Long runs, ultras, and multi-hour endurance efforts
Hot conditions or heavy sweaters
Athletes who prefer to separate fuel and electrolyte intake
Simple. Targeted. Built for long days.
Suggested Use
Suggested Use
Take 1 capsule every 30–60 minutes during periods of heat or heavy sweating.
Always take with water. Adjust intake based on conditions, sweat rate, and sodium already present in drinks (e.g. BareFuel or ClearFuel).
Do not exceed personal tolerance.
