Around 4.2 g net carbs per 100 g — fits a keto day comfortably.
For keto, the key number is net carbs per 100 g: if it's under ~5 g, you're fine; over ~10 g, portions matter; over 20 g, skip it.
4.24 g / 100 g
18 kcal / 100 g
Protein: 0.22 g
Fat: 0.00 g
Target carbs: 5–10% of calories, cap ~30 g/day.
A 100 g portion of beverages, coconut water, ready-to-drink, unsweetened costs you 4.24 g of net carbs. On a typical Keto day with a 30 g carb ceiling, that's 14% of your daily budget.
Pair it with fat and protein to slow glucose response — that's generally good practice regardless of regime.
