Flavor is Amazing

I love these after a long run and the flavor is delicious! There is no fake sweetener taste either which is hard to find with hydration tabs. Would buy again and again!

Small tablet, big difference!

Run, hydrate, repeat! SIS Hydro Tablets make my water flavorful and are perfect for keeping me topped up on those sweaty runs. Small tablet, big difference.

Delivers!

No surprises, it delivers: good taste, not too intense, moderate amount of electrolytes so that you can alternate with other, more high-loaded hydration approaches
