Does it count?
Does juice count as water?
Quick answer
Yes, juice counts toward your daily water intake — 100% fruit and vegetable juices are around 85–90% water. The trade-off is the sugar: even unsweetened fruit juice packs about 20–25 g of natural sugar per glass, so it's best in small amounts. Vegetable juices and diluted juice are gentler choices for everyday hydration.
The short answer
Counts (in moderation)
Counts, but watch the sugar in fruit juice.
Juice is made by extracting the liquid from fruit or vegetables, so it's naturally water-rich. The difference between juice and whole fruit is that the fibre is gone, which makes the natural sugars hit your bloodstream faster. As a small part of your fluid intake, juice is fine; as the main event, it adds up quickly in sugar.
A 1 glass (240 ml) of this drink is roughly 88% water. So in fluid terms, it contributes meaningfully to your day — but the other ingredients matter too. The numbers below compare it to a few other common drinks.
| Serving | Water content | Caffeine |
|---|---|---|
| 1 glass (240 ml) | 88% | — |
| 1 cup (240 ml) (coffee) | 98% | 95 mg |
| 1 glass (240 ml) (milk) | 87% | — |
| 1 mug (240 ml) (tea) | 99% | 40 mg |
The bottom line
A small glass of juice counts toward your water, but reach for whole fruit or water more often — you'll get the same hydration with less sugar.
Whatever drinks you choose, the goal is the same: hit your total daily fluid target, mostly from water. Use the calculator to find that number for your body.

Frequently asked
Is fruit juice as hydrating as water?
Fluid-wise, fruit juice is about 88% water and counts toward your intake. But a glass of orange or apple juice also contains 20–25 g of sugar, which plain water does not, so it's a less efficient hydrator per calorie.
Does vegetable juice count as water?
Yes. Vegetable juices like tomato or cucumber juice are high in water and electrolytes (especially potassium) and lower in sugar than fruit juices, making them a particularly good hydrating choice.
Is diluted juice a good hydration drink?
Diluting juice 50:50 with water roughly halves the sugar while keeping the flavour, which makes it a popular low-sugar sports-drink alternative for kids and athletes.
