Why we love it

Effervescent hydration on-the-go.
Supports muscle function effectively.
Trusted, tested quality assurance.

Main Highlights

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.
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.
