How many tablets are in the SiS HYDRO Tablets tube?

Ten. The SiS HYDRO Tablets tube of 10 is the current generation of Science in Sport's effervescent electrolyte tablet, and it replaces the 20 tablet tube you may have bought before. The tablet itself has not changed. Drop one into 500ml of water, let it dissolve, and you get 789mg of key electrolytes per serving, covering sodium, calcium, magnesium, and potassium, alongside added B vitamins. B1 and B2 contribute to carbohydrate conversion while B6 aids protein metabolism.

This is the low calorie option for when you need electrolytes without the carbohydrate load of a full sports drink. Reach for it before a ride, during sessions under 90 minutes where fueling is not the issue, in hot weather where you are sweating hard, or as a second bottle alongside Beta Fuel on a long day. The compact tube travels well, so it lives in a jersey pocket, a gym bag, or a desk drawer as easily as it does in a saddlebag. All Science in Sport products are endorsed by Informed Sport. Available in Berry, Lemon, and Strawberry & Lime.
