Replace lost salts and minerals while staying hydrated with the best electrolyte drinks…
Electrolyte drinks help replenish the naturally occurring salts and minerals that help balance our bodies’ fluids. These get depleted through exercise, most notably through sweating. The best electrolyte drinks may also often contain carbohydrates and other nutrients to help you stay hydrated and to improve recovery.
What are electrolyte drinks? Here’s all you need to know
But not all electrolyte drinks are created equal. It pays to consider the amount of the electrolytes potassium, chloride and particularly sodium in each drink, which help with preventing cramping, aiding muscle contraction and supporting hydration respectively.
If you’re not a heavy sweater, or need to reduce your intake of sodium for health reasons, you might want an electrolyte drink with lower sodium levels (say, less than 250mg per serving).
Nutritionist Rob Hobson has testes eight of the best electrolyte drinks to help you find one to support your hydration and recovery needs. He tests them for taste, solubility and effectiveness in terms of their hydration and nutritional benefits.
