Zero-sugar flavored water with no fructose or purines; a reasonable soda alternative, though plain water is better for gout.
Vitaminwater Zero (now sold as Vitaminwater Zero Sugar) is a Glacéau/Coca-Cola flavored water sweetened with erythritol, stevia leaf extract and/or monk fruit instead of sugar or crystalline fructose [1]. That matters for gout, because fructose is the sugar most consistently linked with rising uric acid and flare risk. A 500 ml bottle of regular soda can deliver 50–65 g of sugar; this product delivers essentially none, and it contains no purines, no alcohol and no yeast extract.
Zero sugar does not make it medicinal. There is no evidence it lowers uric acid or prevents flares, and plain water is cheaper and equally hydrating. Sugar alcohols like erythritol can cause bloating or loose stools if you drink several bottles quickly. The B vitamins (niacin, B6, B12) appear at low percentages of daily value, so they will not push uric acid up the way high-dose niacin supplements can. Some people also find that sweetened drinks keep a sweet tooth going, making it harder to cut back on sugary sodas and juice.
Treat it as an occasional alternative to soda or juice, especially when plain water gets boring, and keep total daily fluid intake around 2–3 litres. This is general information, not medical advice.
