When you’re pushing yourself to the limit – whether it’s a long-distance run, a high-intensity cycling session, or any other endurance activity – your body needs more than just hydration. It requires a boost that replenishes lost electrolytes and fuels your performance. This is exactly where the STYRKR SLT07 Hydration Tablets 500mg come in. Each tablet is packed with a powerful blend of electrolytes to keep you hydrated and help you perform at your peak.
What I really like about these tablets is their no-nonsense effectiveness. They’re designed to closely match the electrolyte profile of human sweat, promoting optimal fluid absorption while keeping muscle function on track. These effervescent tablets dissolve quickly, providing fast hydration with no added sugars or preservatives.
Who it’s for:
Ideal for athletes training or racing in heat – or anyone sweating heavily. Great for preventing cramps, sustaining performance, or rehydrating quickly after long sessions.
What it does:
Replaces sodium, potassium, magnesium, and calcium lost in sweat in precise 1:0.2:0.05:0.03 ratio’s. Its hypotonic formula speeds absorption, helping maintain fluid balance and muscle function without water loading.
How I’d use it:
Drop one tablet into approx. 500ml water before or during heavy sweating. Shake, sip, and let it do its work. For ultra or gruelling efforts, split a tablet into two doses. Deliciously simple and highly effective.
The Science:
Impact of Electrolyte Tablets on Fluid Retention Using the Beverage Hydration Index
Study: Investigated how electrolyte-containing drinks compare to plain water in fluid retention and hydration efficiency in humans.
Proceedings of the National Academy of Sciences / BHI methodology study (2021)
Electrolyte drinks showed significantly higher fluid retention than plain water, meaning better hydration with the same volume consumed. SLT07’s high sodium formula supports this kind of fluid efficiency perfectly.
Oral Rehydration Solutions with Balanced Electrolytes Improve Performance Over Plain Water
Study: Multiple controlled trials compared carbohydrate-electrolyte solutions (containing sodium, potassium, magnesium) versus plain water during prolonged exercise in heat.
Medicine & Science in Sports & Exercise (2019)
Electrolyte-enhanced fluids significantly improved hydration markers and endurance performance versus water alone – directly supporting SLT07’s use for efficient rehydration during heavy sweating or hot conditions.
