I have to chinchilla l’s and they’ve been kinda stressed lately. Is it okey for me give this to them regularly just to make sure they’re in a good health condition or it may cause any harms?
Answer by ChewyJan 03, 2019
This can be given to Chinchillas daily, long term.

What is the sugar content in this product? We have a diabetic guinea pig and are trying to manage her condition with dietary changes. It isn’t listed on the nutritional info.
Answer by ChewyDec 15, 2017
Oxbow does not guarantee a specific amount of sugar in the product. Any sugar that is in the Supplement comes from the natural sugars found in the ingredients, such as timothy hay.

Can you give these to baby guinea pigs, or just adults?
Answer by ChewyJun 28, 2018
This was formulated for all life stages.

What exactly is the “Fat Product” ingredient?
Answer by ChewyJan 04, 2021
The Fat Product in the ingredients refers to algae-based Omega-3 fatty acids.

Can Not Hurt

While my 2 Cavys enjoy a daily salad of fresh greens and veggies that no doubt gives them all the vitamin C they need, the oxbow Vitamin C tabs while fresh are easy to break apart into small sections which I then place in with their pellet food. I figure that it can not hurt and the only reason I give this product a 4 star review is that one a person opens the package the Vitamin C levels quickly evaporate even with sealing the package evertime it is used. Plus, my Guinea Pigs don't seem overly thrilled by the taste either. They will eat them, but they go for fresh hay over the tabs any day. Plus, lets be realistic. Paying like 10 bucks for a product that must only cost a few cents to produce is poor money management and I bet the package cost Oxbow more than the actual tabs inside do.

Vitamin C tabs

When I first had my guinea pigs I tried giving them the liquid vitamin C in their water bottle. I find you cannot be sure how much or little they wree getting and started giving them Oxbow vitamin C tabs. Now I know they are getting a proper amount and they like them.

These are great!

I like using these Vitamin C cookies/biscuits because you know exactly how much Vitamin C your piggy is getting, as opposed to putting liquid Vitamin C in their drinking water.

Not only does my guinea pig love these so much that the minute I pull the package out she's at her cage entrance squeaking and wheeking like crazy it's like she can tell what I pull out and she comes running to the exact spot that she gets it given to her at I have never seen a guinea pig so happy for something like this and she was a rescue that was so skinny you could see everyone of her when I first got her I've only had her about a month and she's already looking like a normal guinea pig and she's happy as can be. I happily recommend this for anybody with guinea pigs she loves her vitamin C this way my bet other piggies will too

Easy C!

My boys love these! They have become an integral part of our breakfast routine.

loved by all three

I have three Guinea pigs: Alfred, Arlow, and Alberto, and all three go feral for this every morning. I give them half a tab a day each to make it last longer and it’s the highlight of their entire day. I really recommend these especially if you’re worried about their vitamin C intake. You can’t overdose on vitamin C so even if they’re getting enough, a little extra won’t hurt (it might just help).

I give my 6 guinea pigs these supplements every night! When I adopted two of my girls who were malnourished and vitamin c deficient these really helped them bounce back!
