Drinking water is essential, but it can be ineffective for hydration if you don’t have ample electrolytes in your system.

That’s where hydro tabs come in – and they’re especially useful during a heatwave or after exercise.

When we exercise and sweat, electrolytes leave the body and need to be replaced… fast! 

Of course, adequate hydration is important at all times. Athletes are at particular risk of dehydration, which can significantly reduce their performance; therefore, hydro tabs are often used by endurance competitors.

In saying that, the elderly are at a heightened risk of dehydration and could benefit from an electrolyte boost. 

So what are hydro tabs? Are they any good, and if so, when do you take them? These are all questions that we’ll be answering in this article.
