Keto Energy and Sports Drinks: Net Carbs in 20 Drinks
Energy and sports drinks split cleanly in two. The regular versions are sugar drinks: an 8.4 fl oz Red Bull lists 29g of carbohydrate and a 20 fl oz Gatorade lists 36g. The zero-sugar versions mostly list 0 to 5g per can or bottle.
"Zero sugar" does not always mean zero carbs. Red Bull Zero lists 5g of total carbohydrate with 0g of sugar, and Liquid I.V. Sugar-Free lists 5g per stick with allulose as its first ingredient. Those grams are counted here as published, with nothing subtracted.
Every row comes from the maker’s own nutrition facts: Red Bull, Celsius, Alani Nu, Cellucor (C4), Rockstar, the Coca-Cola Company (Powerade), PepsiCo (Gatorade, Propel, Mountain Dew AMP), Liquid I.V. and LMNT. Serving sizes vary from an 8.4 fl oz can to a 20 fl oz bottle, so compare the serving column too.

What to know
- Celsius Sparkling Orange, C4 Performance Energy, Gatorade Fast Twitch, Powerade Zero and Propel all list 0g of carbohydrate per serving.
- Several sugar-free energy drinks still carry a few grams: Red Bull Sugarfree 2g, Rockstar Pure Zero 2g, Alani Nu 4g and Red Bull Zero 5g per can.
- Regular energy drinks are among the highest-carb drinks in the store. A 16 fl oz Rockstar Original lists 64g and a 16 fl oz Mountain Dew AMP Energy lists 58g.
- Gatorade Zero lists 2g of carbs per 20 fl oz bottle against 36g for regular Gatorade Lemon Lime. G2 and Gatorlyte sit in between at 12 to 13g.
- For electrolytes on keto, LMNT (1g per stick, 1,000 mg sodium) and Powerade Zero (0g, 240 mg sodium per 12 fl oz) add the least carbohydrate. Regular Liquid I.V. adds 11g of sugar per stick.
- Allulose and erythritol are counted in total carbohydrate here. FDA guidance lets allulose be left out of the sugar lines on a label, but it still appears in total carbohydrate.
Net carbs in all 20 drinks
Net carbs are total carbohydrate minus fiber, per the serving shown. Low carb means 3g or less, about 15% of a strict 20g day. Plan for it means up to 7g. Every row links to the brand or USDA page its numbers come from, checked October 2026.

Frequently asked questions
The Celsius Sparkling Orange can label lists 10 calories and 0g of total carbohydrate per 12 fl oz, sweetened with sucralose, so it adds no net carbs. It also carries 200 mg of caffeine per can. Flavors can differ slightly, so check the can for the one you buy.
Its carbohydrate is small. PepsiCo lists 2g of total carbohydrate and 0g of sugar for a 20 fl oz bottle of Gatorade Zero Glacier Freeze, about a tenth of a strict 20g day, and under 1g for the 12 fl oz bottle. Regular Gatorade Lemon Lime lists 36g for the same 20 fl oz bottle.
Red Bull lists 10 calories and 2g of carbohydrate for an 8.4 fl oz can of Red Bull Sugarfree, so it fits easily. Red Bull Zero lists 5g of carbohydrate with 0g of sugar. The original Red Bull lists 29g of carbohydrate per 8.4 fl oz, and the larger cans scale up from there.
Some do. Celsius Sparkling Orange, C4 Performance Energy and Gatorade Fast Twitch list 0g, but Red Bull Sugarfree and Rockstar Pure Zero list 2g, Alani Nu Cosmic Stardust 4g and Red Bull Zero 5g per can. "Sugar free" describes the sugar line only, so read total carbohydrate.
Powerade Zero and Propel list 0g, and LMNT lists 1g per stick with 1,000 mg of sodium. Liquid I.V. Sugar-Free lists 5g per stick, and regular Liquid I.V. lists 11g of sugar per stick. Regular Powerade (21g per 12 fl oz) and Gatorade (36g per 20 fl oz) are sugar drinks.
The regular Hydration Multiplier is not a great fit: the Lemon Lime stick lists 11g of carbohydrate, all of it sugar. The Sugar-Free version lists 5g of total carbohydrate and 0g of sugar per stick, with allulose as its first ingredient. FDA guidance lets allulose be left off the sugar lines, but it still counts in total carbohydrate, so this page counts all 5g.
