As you’d expect from one of the best electrolyte drinks brand like SiS, these tablets do exactly what they say on the tin. The most important electrolyte when exercising is sodium, and the amount used in these tablets is science-driven to promote superior hydration.

SiS Go Hydro performance on test
These tablets are suitable for all athletes and are Informed Sports approved, making them a good choice for those engaged in professional competition. The sodium content is high at 870mg, so it’s not a good choice for people who need to restrict their intake of this mineral. But that’s good news for gym goers who tend to sweat a lot during exercise.
The tablets are sugar free and sweetened with sucralose; they also use natural colorings. The strawberry and lime flavor I tested is light and refreshing with a slight tang. You only need one tablet mixed with 500ml of water, so it’s useful for moderate to intense training sessions. I also found that the tablets dissolve quickly in water without any additional shaking.
SiS Go Hydro additional benefits
These tablets contain B vitamins, used in the body to convert food into energy and to support a healthy nervous system and cognition. These vitamins also play a role in electrolyte transport systems in the body. Still, I don’t think they’re really needed in an electrolyte supplement, especially as they’re so abundant in our diet. Some flavors also contain green tea extract, which has a little caffeine. So make sure you check if you’re sensitive to caffeine or tend to train later in the evening.
SiS Go Hydro verdict
