Sodium-to-Potassium Ratio

The sodium-to-potassium ratio describes how a hydration mix balances its two main electrolytes, and it varies widely — some products are almost entirely sodium, others aim for a more even split. It is a useful comparison axis when you are choosing between mixes, read straight off the panel rather than inferred from marketing. We surface it in comparisons; what the "right" ratio is for a given person depends on their diet and activity, which is why we present the number rather than prescribe one.
