Low-FODMAP serving
1/2 glass (96 ml)
Becomes high FODMAP at

Low in a small glass; published serves put the moderate point between 125 and 129 ml, so the tighter figure is used here. Watch for added onion or garlic in vegetable-juice blends.
Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores tomato juice at a serving of 1/2 glass (96 ml); at 2/3 glass (125 ml) or more it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.

How much is OK?
This food's verdict depends on the serving. The bands below show where the load builds, group by group.
Excess Fructose
A full glass (200 ml) is high, with fructans joining the excess fructose at that size — juicing concentrates several tomatoes into one pour. Figures are for 100% tomato juice; savory vegetable-juice cocktails often add onion, garlic or celery, so read the label.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
