SiS GO Hydro Tablets Electrolyte/Caffeine
About the Product
Science In Sport (SiS) GO Hydro Electrolyte Tablets are designed to keep athletes hydrated and performing at their best during intense training and competition. These low-calorie effervescent tablets dissolve quickly in water, delivering a precise balance of electrolytes — especially sodium — to optimize fluid absorption and maintain hydration levels. SiS GO Hydro meets the ideal sodium concentration (30mmol/L) to enhance hydration better than plain water, helping reduce fatigue and boost endurance.

- Supports Performance: Helps delay dehydration-related fatigue and sustain endurance during long workouts or races

- During Workout: Consume 500ml per hour, adjusting intake based on exercise intensity and environmental conditions
- Post-Workout: Continue to hydrate with water and electrolyte drinks to fully replenish fluids and minerals lost
When to Use
- Ideal for athletes engaged in endurance sports, high-intensity training, or events lasting longer than 1 hour

I was looking for a specific SiS gel and couldn't find it anywhere. These guys had it, plus a dozen other flavors I'd never seen! My one-stop shop from now on.
The prices are unbeatable, honestly. I thought there had to be a catch, but my order arrived in literally two days. Insanely fast shipping and great value.
Had a question about my order and the customer service was amazing. So friendly and helpful. You can tell they actually care about their customers.
This is the gold standard. A huge selection, fair prices, and lightning-fast delivery. I don't bother looking anywhere else anymore.
