They are products designed to provide electrolytes and, depending on the formulation, other ingredients such as carbohydrates, vitamins or amino acids. They are commonly available as powders, tablets and sachets.
Electrolytes are minerals that help regulate fluid balance and support muscle and nerve function. Hydration drinks combine water with electrolytes and may include additional ingredients such as carbohydrates.
They can be useful during prolonged exercise, intense training, heavy sweating or activity in hot conditions. For everyday hydration and shorter activities, water and regular meals are generally suitable.

Compare the electrolyte content, carbohydrate levels, serving size and format. Consider your activity, sweat losses and whether you prefer tablets, powders or ready-to-mix sachets.
