UK-based natural sports nutrition provider Protein Rebel has launched Sustain, which is positioned as an all-natural electrolyte powder specifically developed for runners.
The new product is designed to support hydration, muscle function and energy levels during long-distance runs and high-intensity training sessions.
According to the company, Sustain is 100% natural, fast acting and formulated to be gentle on the stomach. The powder’s ingredients are sourced from coconuts, seawater and algae.
Tim Boote, Co-founder of Protein Rebel, said “We wanted to bring to market a truly natural electrolyte powder that’s easily absorbed without causing gastrointestinal issues. We spent many months searching for the right ingredients that were not only sourced from nature, but were backed by research, easy-to-mix and had a neutral taste.
“This work culminated in Sustain which perfectly meets the demands of both training and racing.”
Each serving of Sustain provides 500mg sodium, 200mg potassium, 60mg magnesium, 60mg calcium and 600mg chloride when mixed with water. The company notes that this delivers an effective dose of electrolytes without being excessive.
Tim Boote said “Sweat rate is so variable that Sustain replaces electrolyte losses without overwhelming the system. After all, excessive intake can disrupt mineral balance and cause issues such as muscle weakness, lethargy and vomiting.
“We’ve found that runners can easily tolerate Sustain, and because it’s sugar-free and unflavoured, there’s no risk of flavour fatigue on long runs.”
The product uses vegan ingredients including sea salt, coconut water powder, seawater magnesium and marine algae calcium, with no additional additives.
For use, runners are advised to add one sachet of Sustain to 500ml of water for each hour of their run and sip to thirst. The company suggests the dosage can be adjusted based on personal experience, sweat rate and environmental conditions.
Tim Boote added “Sustain is one of the most natural electrolytes on the market, delivering fast, effective hydration in a powder that’s easy to absorb. Designed for all runners, it supports sustained performance with a low risk of side effects, even under stressful race-day conditions.”
Sustain is priced at £16.95 for a pack of 14.
