Quick Answer
Vitaminwater Zero has 0 calories and 0 sugar per 20oz bottle, sweetened with erythritol and stevia leaf extract. Regular Vitaminwater is a different product: 120 calories and 32g of added sugar in the same bottle. The two get confused constantly, so check which one you are holding.
- Regular Vitaminwater is a soda-level sugar load. 32g uses up most or all of a day’s added-sugar allowance.
- No aspartame in Zero. It uses plant-derived non-nutritive sweeteners instead.
- Caffeine is flavor-specific. Only the Energy flavor has it, at about 60mg. Everything else is caffeine-free.
- It does not hydrate better than water for everyday use, despite the electrolyte content.

In the US, regular Vitaminwater is sweetened mainly with crystalline fructose. At 32g of sugar per bottle, one bottle uses up most or all of a day’s recommended added-sugar limit (the American Heart Association advises under 25g for women and 36g for men) — comparable to many regular sodas, despite the “vitamin” branding. For scale, that is close to the 38g in a can of Sprite.

Does Vitaminwater Have Caffeine?
Most flavors do not. The Energy flavor is the notable exception, carrying about 60mg of caffeine (roughly what is in a small cup of coffee) from guarana extract. Standard flavors and the Zero Sugar line are caffeine-free — check the label if caffeine content matters to you, since it varies by flavor rather than being consistent across the brand.
Does Vitaminwater Hydrate You Better Than Water?
It will hydrate you — it is mostly water — but there is no evidence it hydrates better than plain water for a typical person going about a normal day. The added electrolytes are more relevant during heavy, prolonged sweating (long exercise, heat) than for everyday sipping. Regular Vitaminwater adds the trade-off of substantial sugar for that hydration; Zero avoids the sugar but still costs more than tap water for a benefit plain water already provides in most situations. For drinks actually formulated around rehydration, our Liquid I.V. breakdown explains how the sodium-glucose mechanism works and when it genuinely helps.
Who Made Vitaminwater?
Vitaminwater was created by Glaceau and is now owned by the Coca-Cola Company, which acquired the brand in 2007.
Frequently Asked Questions
Zero calories and zero sugar per 20oz bottle. Regular Vitaminwater is a different product at 120 calories and 32g of sugar in the same size bottle, which is the source of most of the confusion around this drink.
Regular Vitaminwater delivers real vitamins but also 32g of sugar per bottle, similar to a soda. Whether that trade-off is good for you depends on how much added sugar you are already getting elsewhere in your day. It is not a low-sugar or diet drink despite the health-forward branding.
It is a reasonable lower-sugar swap for soda: zero calories, zero sugar, some added B vitamins. It is sweetened with erythritol and stevia rather than sugar or aspartame; these are generally considered safe, though some people experience digestive discomfort from erythritol in larger amounts. It is not a substitute for whole foods or plain water as a daily staple.
Erythritol and stevia leaf extract, with monk fruit extract in some newer flavors. These are non-nutritive, plant-derived sweeteners rather than artificial ones, so Vitaminwater Zero contains no aspartame and carries no phenylalanine warning.
Only the Energy flavor does, at about 60mg per bottle from guarana extract. Standard flavors and the Zero Sugar line are caffeine-free. Check the specific flavor’s label rather than assuming.
