Best Goitrogen Level-Rich Foods for Domestic Rabbits

Ranked by goitrogen level content among foods safe for domestic rabbits in the Creature Feast catalog.

#1
Kale per 100g: moderate goitrogen content — rotate, do not feed daily Kale is a well-known goitrogen source due to its glucosinolate content. Despite this, kale is extremely nutritious — the key is feeding it as part of a rotation rather than daily. A few times per week is perfectly safe.
#2
Broccoli per 100g: moderate goitrogen content — feed a few times per week Broccoli contains goitrogens (glucosinolates) that can interfere with thyroid iodine uptake. Safe in moderation as part of a varied rotation.
#3
Cauliflower per 100g: moderate goitrogen content — rotate with other greens Cauliflower and its leaves contain goitrogens. The leaves are often better tolerated and more nutritious than the florets. Feed in rotation with non-cruciferous greens.
#4
Bok Choy per 100g: low-moderate goitrogen content — safe in regular rotation Bok choy is a milder cruciferous green with lower goitrogen content than kale or broccoli. A good bridging option that provides cruciferous nutrition with less thyroid impact.
