Daily C

Did you know that a lack of vitamin C is the most common nutritional deficiency in guinea pigs? Luckily, it's also the most preventable. A tablet form of vitamin C, such as Oxbow's Daily C, eliminates the guesswork when it comes to making sure pets are receiving a guaranteed, stabilized amount of vitamin C. Sizes: 90 ct.


**Effective September 1, 2014, Daily C will be discontinued. Please note that this product will be available until September 1, 2014, or until all remaining inventory has been liquidated. For customers interested in a replacement for Daily C, we recommend Natural Science Vitamin C - a hay-based, high-fiber supplement containing the essential stabilized vitamin C that guinea pigs need and other animals benefit from during times of stress, illness or recovery.**

Feeding Directions

For guinea pigs, feed one tablet daily. In times of stress, vitamin C requirements may increase. Consult your veterinarian for more information.

  • Hand feed Daily C directly to pet.
  • Place Daily C in pet's bowl.
  • Offer tablet on the floor at playtime, the same as a treat.
  • Place Daily C directly in the mouth.

Vitamin C or ascorbic acid deficiency is the most common and most preventable disease in guinea pigs. Adults must be supplemented with at least 10 mg of vitamin C for every kilogram of body weight. Pregnant, nursing and growing guinea pigs need at least 30 mg of vitamin C for every kilogram of body weight. Insufficient vitamin C intake leads to a condition known as scurvy. Clinical signs of vitamin C or ascorbic acid deficiency may include rough coat, anorexia, diarrhea, bleeding from the gums, lameness and pain. Delayed wound healing and increased susceptibility to bacterial infections may also occur.


The usual supplementation method of adding vitamin C to water often changes its taste, and thus intake may be adversely affected. Daily C has a pleasant flavor and is readily accepted by most guinea pigs.

Guaranteed Intake

Feeding a tablet guarantees that pets receive the entire guaranteed amount of the supplement necessary for optimum health.  Supplements lose their potency when added to water.  Animals may refuse or reduce the amount of water due to the taste of a water soluble supplement, which may lead to other health problems as well.  Feeding a tablet, on the other hand, lets pet owners take the guesswork out of supplements.


The bioavailability of Daily C is substantially higher than that of dissolved sources. Water soluble powders have a low stability in water; only 20% of the vitamin C sources remain after 8 hours in water.

“I think these are wonderful products tailor made for the myriad of species seen in veterinary medicine today. I especially like the chewable vitamin C tabs for guinea pigs-my guinea pig “Matty” thanks you Oxbow!”

    My Guinea Pigs love this Vitamin C
    Rating 5 out of 5
    My guinea pigs love this Vitamin C tablet as well and it's very disappointing that these tablets are being discontinued. It's hard to find a suitable replacement, particularly here in Australia. My guinea pigs are not a fan of the Natural Science Vitamin C tablet.. I totally agree with Marsha and also hope you reconsider discontinuing this Vitamin C tablet.
