Best Vitamin B3 (Niacin)-Rich Foods for Guinea Pigs
Ranked by vitamin b3 (niacin) content among foods safe for guinea pigs in the Creature Feast catalog.
#1
Timothy Hayper 100g dry: ~1.0-2.0mg niacinTimothy hay provides a foundation of niacin in the guinea pig diet. Combined with partial synthesis from tryptophan and additional production by cecal bacteria, hay-fed guinea pigs generally meet their niacin needs without difficulty. Quality hay that has been stored properly retains its niacin content well.
#2
Peasper 100g: ~2.1mg niacinPeas are among the better vegetable sources of niacin for guinea pigs. A few fresh or thawed peas as an occasional treat provide a meaningful niacin boost. Peas also supply tryptophan, which guinea pigs can partially convert to niacin, adding an indirect benefit.
#3
Bell pepperper 100g raw: ~0.98mg niacinBell peppers provide moderate niacin alongside their star nutrient, Vitamin C. Because bell peppers are a daily vegetable for many guinea pigs, they contribute a steady baseline of niacin to the overall diet.
