This is a specific conversation about Guinea pig supplies — the essentials — ask about yours and get one honest answer for your exact situation.

Switching pellets is a great move — store-brand guinea pig pellets often bulked out with fillers and low on the vitamin C guinea pigs genuinely need. Before I point you toward a specific upgrade, can you tell me a little more? Are your two White Crested piggies in good health generally, and is there a particular reason you're making the switch now — coat condition, digestion, just wanting better ingredients? And are you looking to swap out pellets only, or review their whole diet?
They seem healthy enough but one of them, Pebble, has had slightly loose stools on and off. Their current pellets are a supermarket own-brand. I just want something with better ingredients — mostly the pellets, though I'd take any other tips.

Loose stools in guinea pigs often come down to two things: too much sugar in the pellets, or an inconsistent diet. Supermarket own-brands frequently use grain and molasses as filler, which can cause exactly what you're describing in Pebble. The switch you're planning should genuinely help. One thing to flag: how are you currently serving hay? It should make up about 80% of their diet — unlimited Timothy hay every day. If that's already in place, better pellets will almost certainly settle Pebble's digestion.
Yes, they always have hay — I use a big hay rack. So what pellets would you actually recommend?

For an 18-month-old pair, I'd go with Burgess Excel Guinea Pig Nuggets with Blackcurrant and Oregano. It's a straightforward, well-formulated nugget — no muesli-style mix that lets them selectively eat the sweet bits, good vitamin C levels, and no added sugars or artificial colours. The blackcurrant and oregano aren't gimmicks; oregano in particular has mild prebiotic properties that can help with loose stools. It's widely available on Amazon UK in 2kg bags, which is a sensible size for two piggies. Transition slowly over about ten days — mix increasing amounts of the new pellet with the old one so their gut bacteria adjust without a shock.
That sounds good. How much should I be giving them per day?

About one tablespoon of nuggets per guinea pig per day — so two tablespoons total for your pair. That sounds like very little, but remember pellets are a supplement to hay and fresh veg, not the main event. Overfeeding pellets is actually a common mistake that contributes to obesity and bladder sludge in guinea pigs. Keep the hay truly unlimited, add a small handful of fresh leafy greens each day — romaine, kale, or fresh herbs like parsley work well — and the pellets just top everything up. At 18 months they're adults, so this ratio is right for them long-term.
Perfect, that's really helpful. I'll order the Burgess Excel and do the gradual switch.

Good plan. Give it two to three weeks before judging the results — Pebble's digestion should settle once the transition is complete and the new pellets are established. If loose stools continue beyond that, it's worth checking fresh veg quantities (watery veg like cucumber given in large amounts can also be a culprit). Enjoy your piggies — White Crested guinea pigs are lovely.
