Best Carotenoids-Rich Foods for Guinea Pigs

Ranked by carotenoids content among foods safe for guinea pigs in the Creature Feast catalog.

Carrot per 100g: ~8285mcg beta-carotene Carrots are the iconic carotenoid source — their orange color comes from concentrated beta-carotene. A thin coin-sized slice provides meaningful beta-carotene that guinea pigs can convert to Vitamin A. Carrot tops are also rich in carotenoids and lower in sugar than the root.

Bell pepper per 100g red pepper: ~3131mcg beta-carotene (plus capsanthin and other carotenoids) Red bell peppers are rich in both beta-carotene and other carotenoids, including capsanthin (the red pigment). They deliver exceptional carotenoid diversity alongside their outstanding Vitamin C content, making them a nutritional powerhouse for guinea pigs. A daily slice provides broad antioxidant coverage.

Kale per 100g raw: ~5927mcg beta-carotene (plus lutein and zeaxanthin) Kale is packed with carotenoids including beta-carotene and lutein. Its deep green color masks the orange pigments. A few torn leaves several times per week provide significant antioxidant protection. Kale's carotenoid content actually increases slightly when the leaves are chopped or torn, as cellular disruption releases more pigments.

Pumpkin per 100g raw: ~3100mcg beta-carotene Pumpkin provides abundant beta-carotene, evident in its deep orange flesh. A small raw cube offered a couple of times per week contributes meaningful carotenoids. The flesh should be raw and cut into small pieces — guinea pigs can gnaw it directly.
