Science in Sport GO Electrolyte Drink Mix is an electrolyte with 194 mg of sodium and 0 mg of potassium per serving and 37 g of carbohydrate. It scores 36/100 on the CarbRate Science Score, which judges electrolyte products on sodium delivery, not on carbs. Pair it with a separate carbohydrate source.
Who GO Electrolyte Drink Mix suits
Runners who want a light electrolyte top-up rather than a full replacement. At 194 mg per serving, heavy sweaters will need more than one.
Runners fueling carbs from gels or chews who want electrolytes they can dose independently of energy.
Runners with dietary limits: it is vegan and gluten-free according to the manufacturer.
How to use it in a race
Dose by sweat rate, not by the packet. Heavy sweaters in heat may need 500 to 1000 mg of sodium per hour, which at 194 mg per serving is 4 servings an hour as a middle estimate.
Take it with water, and take it on a schedule from the first hour rather than waiting for cramps or a headache. Sodium has no effect on cramping, but it does keep you drinking and keeps plasma volume up.
Servings per hour assume the 37 g per serving on the label. The finder sets your own g/hr target from race distance, sweat and gut.
Why it scores what it does
Computed from verified label data with the same evidence rules for every product. Retailer relationships play no part in the score.
194 mg sodium per serving — light; you may need more than one per hour in the heat.
Sodium only — no potassium listed.
Carries meaningful carbohydrate — count it toward your carb target, not just hydration.
