Can I Give My Dog Vitamin C?

Can Dogs Take Vitamin-C?Vitamin C is a super supplement. People get conflicting info about giving it to their dogs. It’s obviously healthy, but canines only benefit when extra is necessary. That’s rare.

Get Fast Answer

Dogs produce their own vitamin-C. We do not have that ability. People require this vitamin more so than their pets. There are, however, cases where supplementation makes sense.

Your dog may not have a healthy glandular system. Perhaps their ascorbic acid needs aren’t being met. Let’s go into detail about vitamin-C as it applies to a deficient four-legged friend.

Can I Give My Dog Vitamin C? Answer: Yes, when necessary

It makes sense when there’s a good reason to provide extra. The sodium ascorbate version is preferred.

We recommend Ester-C Canine because of its¬†antioxidant properties. It also won’t irritate your dog’s GI tract. People often relate¬†oranges¬†to vitamin-C. Kale, kiwi, grapefruit and other fruits also contain high doses.

Here we will focus on pure vitamin C and its use for dogs with this vitamin deficiency.

Vitamin C Use for Canines

Certain medical conditions respond well to vitamin-C supplementation. This is especially true for older dogs. A serious deficiency may warrant a vitamin C injection. Powdered form, for pets, is most popular.

If a dog is under stress it could indicate low levels of vitamin C. A supplement sometimes makes sense. It’s difficult to determine which is why a professional can help.

It’s a Powerful Supplement

Vitamin C is an essential nutrient. It can help dogs with cataracts, joint inflammation (arthritis), glaucoma, kennel cough, certain infections, abscesses and upper respiratory conditions.

It can also play a role in recovery of injuries, provide an immune system boost and even fight canine cancer. Some dogs certainly benefit from additional vitamin C when appropriate.

The Potential Side Effects

Be careful about giving vitamin C to your pet dog. Often they don’t need it. It could harm their ability to produce their own, perhaps¬†permanently.

Some dogs may become internally stressed, meaning their organs may be working extra hard. It’s important not to inappropriately provide this vitamin.

Too much means they’d have to rid their body of it. This may cause diarrhea, a sign of excessive vitamin-C. Serious complications involve kidney stones and organ failure, specifically the liver and kidneys.

S. Ascorbate & Ascorbic Acid

Confusion also surrounds vitamin C, partly because there are several different forms on this amazing supplement. Dogs, the way their systems function, are better suited for sodium ascorbate.

Ascorbic acid is an inferior form of vitamin C for both man and canine alike. The concentration and highly acidic nature of ascorbic acid can affect your dog’s kidneys and liver.

Non-acidic sodium ascorbate, in theory, is desirable for dogs. There’s also evidence to suggest it’s more effective since it is better absorbed.

Conclusion on Vitamin-C

Supplementing a dog’s diet with vitamin C is sometimes appropriate. This assumes they are deficient or need extra for a medical condition. It’s questionable for healthy dogs. They produce their own vitamin-C. Too much could be harmful. Discuss adding extra vitamin C with a vet. Learn about other supplements, like¬†iron and calcium, as they apply to dogs.
