Best Iron-Rich Foods for Guinea Pigs
Ranked by iron content among foods safe for guinea pigs in the Creature Feast catalog.
#1
Spinachper 100g: ~2.7mg iron (non-heme)Spinach has the highest iron content among guinea pig-safe vegetables. Since guinea pigs are herbivores, all their iron is non-heme (plant-based), which has lower bioavailability than heme iron. Pairing spinach with vitamin C-rich foods like bell pepper dramatically improves absorption. Limit to 1-2 times per week due to oxalate content.
#2
Parsleyper 100g: ~6.2mg iron (non-heme)Parsley is an excellent iron source for guinea pigs, and its own vitamin C content helps improve iron absorption right in the same bite. Feed a few sprigs 2-3 times per week — the high calcium means it should be rotated rather than given daily.
#3
Dandelion greensper 100g: ~3.1mg iron (non-heme)Dandelion greens provide solid iron along with prebiotic fiber that supports the gut bacteria guinea pigs rely on for cecal fermentation. The lower oxalate content compared to spinach means the iron is more bioavailable, making dandelion greens a practical regular source.
#4
Kaleper 100g: ~1.5mg iron (non-heme)Kale delivers moderate iron with much lower oxalate levels than spinach, so its iron is better absorbed. Kale's vitamin C content further boosts non-heme iron absorption. Rotate with low-calcium greens to manage total calcium intake.
#5
Peasper 100g: ~1.5mg iron (non-heme)Peas are an underappreciated iron source for guinea pigs, combining iron with protein and fiber in a crunchy package that most guinea pigs enjoy. Feed whole sugar snap pods for the added fiber benefit from the pod itself.
