Generally Safe

A vitamin C powerhouse

Like humans, guinea pigs cannot synthesise their own vitamin C and must get it from food. Bell peppers are one of the best sources, while staying low in sugar and calcium, making them a near-ideal fresh vegetable.

Why are bell peppers good for guinea pigs?

Guinea pigs lack the enzyme needed to produce vitamin C, so a deficiency (scurvy) is a real risk without a steady dietary source. Bell peppers are exceptionally rich in vitamin C — red peppers especially — which supports the immune system, healthy skin and proper healing.

Just as importantly, bell peppers are low in sugar, oxalate and calcium, so they avoid the bladder-stone and weight concerns of richer vegetables. Served raw with the seeds removed, a few strips several times a week make a safe, nutritious addition to unlimited hay.

Red is richest

All colours are safe, but red bell peppers contain the most vitamin C and a little more natural sugar; green peppers are lowest in sugar. Variety keeps the diet interesting.

How to serve bell peppers

1
Wash thoroughly. Rinse to remove any pesticide residue before serving.
2
Remove the seeds and stalk. Offer just the flesh, cut into manageable strips.
3
Serve raw. Raw peppers retain the most vitamin C — never cooked or seasoned.
4
Keep hay unlimited. Fresh veg complements, but never replaces, grass hay.
