Hydration should be simple, reliable and repeatable. SiS Hydro Electrolyte Tablets deliver fast‑mix, virtually calorie‑free hydration in a compact per‑tube format that fits the way athletes actually train. Each effervescent tablet is formulated with 4 key electrolytes (sodium, potassium, magnesium, calcium) to help maintain fluid balance and support normal muscle function during exercise and daily life. Added B‑vitamins (B1, B2, B6) contribute to energy‑yielding and protein metabolism so your routine stays aligned with workload. Using Hydro is straightforward: add one tablet to 500ml of water, allow it to dissolve, and consume the prepared drink within 24 hours. For shorter efforts where carbohydrate intake isn’t required, many athletes aim for approximately 500ml per hour, adjusting to heat, humidity and individual sweat rate. On longer or harder days, stack Hydro with carbohydrate sources to meet hourly energy targets while keeping fluid and electrolyte intake consistent. Always avoid exceeding 4 tablets per day. SiS products are Informed‑Sport certified, meaning every batch is tested against the WADA banned substances list for peace of mind in training and competition. The tube is tidy and portable for everyday readiness – keep one in your kit bag, rucksack or desk so staying on top of hydration becomes automatic. With a flavour‑neutral listing and no pack‑size commitments, you can choose the option that fits your plan while purchasing by the tube.

EFFERVESCENT ELECTROLYTES, READY WHEN YOU ARE: Purpose‑built hydration you can carry anywhere. Drop one tablet into 500ml water, let it dissolve, and sip during training, travel, or work. Designed to replace key salts lost in sweat without heavy sugars – virtually calorie‑free for days when energy intake comes from separate sources. Per‑tube format makes stocking, stashing and sharing simple across gym bags, desk drawers and kit boxes while avoiding bulky bottles or sticky mixes. 1 tube each of Berry, Lemon, Strawberry & Lime and Pink Grapefruit.
4 KEY ELECTROLYTES + B‑VITAMIN SUPPORT: A balanced profile featuring sodium, potassium, magnesium and calcium supports fluid balance and normal muscle function. Vitamins B1, B2 and B6 contribute to energy‑yielding and protein metabolism, aligning intake with training demands. A clean, refreshing drink helps maintain routine compliance in heat, double days and indoor sessions when airflow is limited. Build a dependable hydration foundation you can repeat every week.
TRUSTED QUALITY – INFORMED‑SPORT TESTED: Every batch is independently screened under the Informed‑Sport programme against the WADA banned substances list, giving confidence from base miles to race day. Clear labelling and batch codes support traceability, while the tidy tablet format keeps hands and bottles cleaner than powdered scoops. Ideal for athletes who can’t compromise on quality or convenience—simply drop, dissolve, drink and keep your session on schedule.
SIMPLE USAGE, CLEAR LIMITS: Mix 1 tablet with 500ml cold water and allow to fully dissolve. Consume prepared drink within 24 hours. During exercise where carbohydrate isn’t needed, target ~500ml per hour as a starting point and adjust to conditions and sweat rate. Do not exceed 4 tablets per day. Combine with carbohydrate gels or drinks on longer, harder days; add electrolytes first, then layer energy as intensity and duration climb.
CONVENIENT: The compact, crush‑resistant tube travels well, slots into bottle cages, vest pockets and desk drawers, and helps you plan fluid intake anywhere – commutes, altitude stays, heat training blocks, team practice or back‑to‑back workouts.
