Sis Electrolytes

Science in Sport (SiS) electrolyte tablets—primarily known as SiS GO Hydro—are low-calorie effervescent tablets designed to dissolve in water to replace essential minerals lost through sweat. Originally developed to keep the British sailing team hydrated at the 2008 Beijing Olympics [0.15], they are widely used by runners, cyclists, and endurance athletes to maintain fluid balance and prevent muscle cramps.

⚡ Key Features & Formulation

• Low Calorie & Low Sugar: Contains virtually zero calories and less than 1g of sugar per serving, making them ideal when you need hydration without an extra carbohydrate load.

• Electrolyte Blend: Delivers a scientifically backed 30mmol/L sodium concentration alongside potassium, calcium, and magnesium to promote superior fluid retention compared to water alone [0.15].

• Vitamin Enhancement: Enriched with B vitamins (B1, B2, B6) to help support standard energy metabolism.

• Dietary Friendly: The formula is completely vegan, gluten-free, and dairy-free.

• Quality Assurance: They are Informed-Sport certified, meaning they are rigorously tested for banned substances and safe for competitive athletes.

🥤 Product Variants & Flavors

The tablets come in portable tubes of 20 effervescent servings and are split into three primary lineups:

1. SiS GO Hydro (Original): Focused purely on hydration. Popular flavors include Berry, Lemon, Pineapple & Mango, and Strawberry & Lime.

2. SiS GO Hydro + Caffeine: Includes 75mg of caffeine per tablet (such as the Cola flavor) to provide a mental stimulation and focus boost alongside hydration.

3. SiS Immune: Features a low-calorie hydration base supplemented with Vitamin C and Iron to support the body's immune defenses during heavy training blocks.
