Best Vitamin B7 (Biotin)-Rich Foods for Guinea Pigs
Ranked by vitamin b7 (biotin) content among foods safe for guinea pigs in the Creature Feast catalog.
#1
Timothy Hayper 100g dry: ~0.01-0.03mg biotin (plus indirect production via cecal fermentation)Timothy hay provides a modest baseline of biotin, but the most important biotin source for guinea pigs is actually their cecotropes — soft, nutrient-rich droppings produced by cecal bacteria and re-eaten for nutrient absorption. Hay fuels the cecal bacteria that produce biotin, making it indirectly the most important biotin 'source' even beyond its direct content.
#2
Pumpkinper 100g raw: ~0.4mcg biotinPumpkin provides trace biotin alongside its beta-carotene and fiber. A small cube of raw pumpkin offered a couple of times per week contributes to biotin intake. Guinea pigs generally enjoy pumpkin's sweet flavor and soft texture.
#3
Carrotper 100g: ~0.6mcg biotinCarrots contribute trace biotin. The amounts are small, but combined with hay, cecotropes, and other vegetables, every little bit counts toward maintaining a thick, glossy guinea pig coat. A thin carrot coin once or twice a week is appropriate.
