Frequently asked questions

What is the difference between Electrolytes, Isotonic Drinks and Other Hydration?

Electrolytes lists electrolyte products, whose labels name minerals such as sodium, potassium and magnesium, in forms including powders, tablets, shots and concentrates. Isotonic Drinks lists powders sold as isotonic mixes, and Other Hydration lists the remaining hydration mixes, mostly flavoured powders in tubs. Compare the minerals and carbohydrate per serving in all three.

How do I compare the minerals in two hydration products?

Compare sodium, potassium and magnesium in milligrams per serving. Potassium and magnesium also show a percentage of the nutrient reference value, which is 2,000 mg and 375 mg respectively, while sodium has no such value; where a label gives salt instead of sodium, salt is sodium multiplied by 2.5. Use the same serving for both products.

How do the tubs, stick packs, tablets and shots in this category differ?

A tub of powder holds many servings, each measured with a scoop in grams and mixed with the water the label states. Stick packs and effervescent tablets are single servings dissolved in water, and the pack states how many it holds. Shots and liquid concentrates are used as directed, and capsules and tablets are counted per daily serving.
