The secret powers of vitamin C

vitamin c for cats and dogs

Last year, when my dog Roxie was diagnosed with cancer, I immediately came home and spent hours and hours researching things that would help get her better.  A lot of the supplements I read about that were recommended, I’d never heard of. There was one that caught my attention though, because of how it is administered in dire cases and what ailments it can help with in both cats and dogs.  It was vitamin C.  I never realized how many things vitamin C was good for treating in cats and dogs until I researched further.

How I stumbled across vitamin C

As soon as my dog Roxie got her cancer diagnosis and seeing how quickly her health was deteriorating, I knew if there was any chance of saving her, I had to find what would work the best and the quickest.  Unfortunately, what I read about treating cancer successfully with vitamin C, involved it being injected intravenously in very high doses.

Because that wasn’t an option for me, I tried to find the next best thing.  Somewhere I’d read about liposomal vitamin C that was supposed to be better absorbed by the body than conventional vitamin C.  I set about trying to find the best brand of it I could find.

Lypo-Spheric Vitamin C

Lypo-Spheric Vitamin C

During my research, I ran across this Lypo-Spheric Vitamin C here,, where the first review was from someone who had a senior poodle with pneumonia that had basically been brought home to die because it was so sick.  With around the clock dosing, the dog had been brought back to life.  It was the encouragement I really needed at that moment to show me that miracles were possible.

After reading through some more information and the reviews, I decided to order it for overnight delivery and get Roxie started on it right away.  Along with several other supplements I’d ordered for her, I hoped I’d somehow found the magic concoction of things that would save her.

In the past, prior to treating Roxie’s cancer, I’ve taken vitamin C in capsule form along with Echinacea to stave off or treat colds.  I’ve also given it periodically to one of my dogs as an ingredient in Dr. Pitcairn’s “Healthy Powder” recipe.

Also, on at least one occasion, I used it as sort of an antibiotic, like when I gave it to one of my new dogs after he got into a skirmish with another male dog I have.  Their tussle resulted in a puncture wound on the new dog’s chest. He was reunited with his owner before I got to see how he healed up after being given the vitamin C, but his wound wasn’t that bad before he left, so I’m not sure I would have been able to tell if it was actually helping.

Up to that point, healing things like infections in animals or treating a cold I was getting or got, was really only what I associated using vitamin C for.

Using vitamin C  as part of a vaccine counter protocol 

In his book, ‘The Nature of Animal Healing’, Dr. Goldstein, a holistic vet whose book I reference often, recommends a vitamin cocktail, including vitamin C, be given to cats and dogs two to three weeks prior to and after vaccinations.  Dr. Goldstein recommends this to help boost the immune system to counter the barrage of multiple diseases forced on it at once.

I’m not going to go into the details, including the amounts he recommends, as I just wanted to point out the use of vitamin C as part of a vaccine counter protocol.  I have read a lot about how to counter the effects of vaccines, with things like Thuja, but this was the first I’d ever heard of using vitamin C.

Vitamin C for numerous cat and dog ailments

Dr. Goldstein also discusses how vitamin C can help deter hip dysplasia and other joint inflammation by enabling the immune system to properly mobilize calcium, which helps keep bones and joints from deteriorating.  He also shares his protocol for cats diagnosed with leukemia and other cancers, as well as feline lower urinary tract disease (FLUTD), based on Dr. Wendell O. Belfield’s work.  Dr. Belfield is a well-respected holistic vet known for treating pets with virtually every form of serious illness using massive doses of vitamin C intravenously.

In addition to helping deter hip dysplasia and joint inflammation, and fighting cancer in cats, vitamin C is also recommended and has been used for, protection against heart disease and respiratory issues.  As the body is subjected to more and more stress, the more it needs help with vitamin C supplementation to restore the balance.

Stress can be emotional or physical, like relocation or getting vaccinated.  Due to the stress, the vitamin C a dog normally produces on its own decreases.  In younger dogs, common stressors include surgery, rapid growth, and vaccinations.  With older dogs, it is more a need for antioxidants.

Dosing information

Several resources I looked at offered differing dosage amounts, based on different factors or guidelines.  Having to take into account the severity of the disease, amount of stress and if that stress amount changes, as well as the size of the animal, you can see how it’s hard to be a one-size-fits-all dosing schedule.

With so many variables, I don’t feel comfortable just giving random dosage amounts out to be followed.  They are available,  but with most things pet related, one size does not always fit all.  This is not an area I am well versed enough in to be that comfortable, either, to offer my own experience.

With Roxie, I was just trying to get enough high doses of vitamin C into her to fight the cancer.  One site did say that a healthy dog produces 18mg of vitamin C per day, per pound of body weight, so you could roughly calculate your dog’s vitamin C maintenance dose requirements using that formula.  I read that many holistic veterinarians take that number and multiply it by 3-4x for a maintenance dose.

Monitoring vitamin C

In my research, I also found that for therapeutic dosing in dogs, it was recommended to start with a conservative dose spread out over several feedings.  Every couple of days, increase the amount by 100 to 500 mg, to the point that diarrhea starts.

I recommend writing the dosage amount and time given, along with your increasing amounts on a calendar, so you can track the dates, times, and amounts easily.  Check off if that day and the dosage amount given produced a solid bowel movement day.

Once your dog gets diarrhea, that means it has taken too much vitamin C and you’ll want to back off to the previous days’ amount, before the diarrhea started.  That should be the amount of vitamin C that particular dog can handle.  Just to be safe, I recommend continuing to monitor their bowel movements in case more reductions need to be made.

From what I’ve read in Dr. Goldstein’s book, as well as online, it appears vitamin C is pretty commonly used by holistic vets.  As always, if you have access to a holistic vet, please try to go that route to get the most accurate diagnosis and treatment information.

Whatever way you arrive at administering vitamin C, just remember that it’s important to keep an eye on the stool consistency.   An already stressed dog doesn’t need unchecked diarrhea to deal with on top of whatever issue you are trying to cure.  As a matter of fact, you should always monitor your pets’ bathroom habits, and definitely when it’s on any form of medication or supplement.

My personal use of vitamin C

My current personal vitamin C regimen now includes taking the Lypo-Spheric Vitamin C, at the first sign of feeling like I might be coming down with something.  I decided to first try it after having some left from treating Roxie.  The couple of times since last December that I’ve felt a little “off”, I’ve taken it.  The first time I took it, I also included Echinacea, but the 2nd time, I took it without anything else.

Both times, within a few hours, I felt fine again.  Having been impressed with just those two times taking it, and not having the option of a sick day, I’m going to be a permanent user.  Despite the price, only having to take a dose or two to avoid being sick is worth it.  It also comes in 30 little individual packets, so you can send some with the kids to school, keep some in your purse or your desk at work, in case you start feeling bad while away from home.

The directions say to pour the gel-like orange goo into a small amount of water and drink it.  I find it’s just easier to open the packet, squirt the contents into my mouth, then take a drink of something to wash it down.  Otherwise, you have to drink a small glass of water containing a goo glob that doesn’t disintegrate.

Vitamin C for peace of mind

Having the Lypo-Spheric Vitamin C on hand is also peace of mind knowing that in case of emergency, I have it on hand for one of the animals.  My Solaray Vitamin C caplets are nearly out and I’ve been researching affordable brands to start on my two seniors who are both around ten years old.  I like this powder form,  since Abby, my lab, isn’t a fan of pills, but has no problem eating the powder inside them sprinkled over her food.

If you are interested in purchasing Dr. Goldstein’s book, which overwhelmingly had more information than all of my other pet reference books combined on this subject, here is the link: The Nature of Animal Healing: The Path to Your Pet’s Health, Happiness, and Longevity.  I also did a review of all of the holistic vet books I own recently, all of which at least touched on this vitamin C topic, here, if you are wanting to start or add to your own holistic pet care book collection.

  1. My dog Rocky was diagnosed with fibrosarcoma back in May 2016 and given 3 months to live.
    He is alive and well

    I gave him powdered vit C and Alpha Lipoic acid.
    He also eats a Ketogenic diet.

    1. Kathryn, that’s amazing! I love hearing stories like yours. Congratulations on going outside the conventional medicine box and saving Rocky. I hope you guys have many more happy, healthy years together!

  2. I, too, am a fan of this product. We first used it when my brother was diagnosed with cancer. It gave him much needed energy and prolonged his life.

    I am a foster/rescue person as well. I presently foster seven cats and two dogs. One of my dogs has been diagnosed with heart disease as well as an enlarged liver and spleen. He almost died about a week ago and has been at the vet hospital since, stabilizing his condition. They offer little hope except to make him comfortable.

    I remembered using this product for my brother and had wondered if it could be given to animals as well. Because Vitamin C helps oxygenate the blood, I thought it, along with B12 would be helpful for my little friend. Thanks to your article, I feel comfortable in giving him this supplement, and because of what you wrote, I also now have a guideline to follow.

    This was very helpful. Prayers and good energy for your continued work with our four legged friends.

    1. Zande,

      Thank you visiting my site and for your foster/rescue work as well! I’m sorry to hear about your dog’s health problems. I’m glad you found this information helpful and I hope it helps your dog.

    1. Darcy,

      Depending on how picky your cat or dog is, there are a few tricks that I shared in my post ‘Tricks for giving medicine to cats and dogs’, Those tips also apply to supplements. The secret is to disguise the taste either in food (stirred in) or hidden in a piece of food. I’ve cut a slit in a piece of pork before for my dog who tends to avoid pills and stuffed the pill inside then hand fed it to her. For my cats, I add a little bone meal to the green mix powder to make sure they eat it all. You might be able to do that for the vitamin C if you are giving it as a powder. It kind of takes some experimentation as some animals are super picky and some are not, so it’s not a one size fits all solution, unfortunately, but I think between my other post and what I’ve shared here, you hopefully have something that will work for you and your pet(s).

  3. Hello,
    I am so happy to find this site. I read Wendell Belfield, DVM book, “How to have a healthier dog & cat” in 1996 and it changed my life. (I am also a big fan of Linus Pauling, MD the father of vitamin C discovery). He just passed away recently but sounds like you are on his track. If you can get a hold of the book it has much useful information regarding Vitamin C, how stress affects the depletion of it, and how animals can benefit from it. I use sodium ascorbate in all my cats food as a supplement. I am going to look into ordering your product. I have a cat right now who was attacked by a coyote and his wound will not heal. He is FIV positive and that is not helping. I wish I could find a veternarian who would use intravenous vitamin C, but have not yet.
    I live in Southern NJ.
    Thank you. Bernie

    1. Hi Bernie,

      Thank you for taking the time to comment and share your knowledge and enthusiasm about vitamin C. I recently ran across information that says taking MSM with vitamin C helps it work better. I have more research to do, but here’s an article that might be helpful to you and/or others.

      I responded to your comment about your cat’s wound not healing via e-mail with the recommendation to try colloidal silver along with the article I wrote about it. I’ve written a couple of articles about it now and will have more coming up, but suffice it to say that I wouldn’t be without it.

      Not sure if you’ve tried to find a holistic vet or not to help you with the intravenous vitamin C, but here’s a link that might help you find one,

  4. Hello!
    My name is Birgit. I´ve tried lipsomalt c-vitamin for myself. My dentist going to take away amalgam from my teeths and I was recommended to take liposomalt c-vitamin. After taking two I noticed that the pain I felt in my jaws disappered. I have also cats. I know about Belfield and his work. I have tried in powderform, but it hasnt helped. But I started to search on google and found the c-vitamin You used. So I´ve ordered it and wait for it. I have one cat who has mammarytumour and one with catflu so I´m going to try it on them.

    1. Hi Birgit,
      I’m glad you found relief with vitamin c and I’m sorry to hear about your cats. In addition to the liposomal vitamin C, I strongly encourage you to add colloidal silver to your cats’ medical treatment plan. I have no experience with either of your cats’ health problems, but there are a lot of helpful groups on Facebook with people who have and are dealing with them that I’m sure would be helpful. Just a quick search I found mentioned using CBD oil (on tumor and internally), ldn (low dose naltrexone), and switching to organic raw food. Here are some groups that were mentioned that you might find helpful:,,,,, and here’s a website someone suggested that you might find helpful:

      From my own experience and reading lots of posts from others, fighting cancer usually requires more than one product/thing, though all pets, like people, respond differently. I do think these groups and website will give you a good place to start to do your own research as to what is available in your area and has proven to be most helpful with the treatment of both of your cats. Best of luck to all of you!

  5. Hi, I just wanted to say one of my three dogs started coughing, after two days another dog started. I opened a packet of lypo c dipped my finger in it and rubbed it in the dogs gum and tongue. Two doses and cough had stopped on the first dog, one dose on second dog.
    I’m looking at this site today to gauge the amount of lypo for a cat with a ear infection that just will not disappear completely. (Am using collidial silver and homeopathic remedies) Will post success if I can find may way back!

    1. Thanks for sharing your success with vitamin C, Vicky. I’ve used colloidal silver on ear infections in my cats a couple of times now and it’s worked really well. Not sure what brand of colloidal silver you are using, but some are better than others. I’ve had excellent luck with Sovereign Silver (there’s a link for it on my Amazon page under the ‘Shop’ tab at the top of the page). Please do try to come back and share any information you have on how you successfully used liposomal vitamin C on your cats.

  6. I have been using colloidal silver for many year, and I swear by it! I’m glad you’re a proponent of it as well. The one I use probably isn’t a very good one, because I make it myself with distilled water and immersed silver rods, battery, “jumper cables”, etc. I’m sure the particle size is larger than it should be, but I have still had much success when administering it to myself and my hoard of cats, for almost any sickness or issue. I will now search for the Vitamin C that you recommend, as my whole gang seems to have contracted and spread feline herpes throughout. Would you think the Vit-C might help with the discharge and respiratory issues connected with that?

    1. Renate,

      I am absolutely a proponent of colloidal silver and I too, make my own. Yes, adding vitamin C should help your cats. In his book, Dr. Goldstein (which I referenced to help us here) says that a fast of chicken or bone broth will speed the virus. He didn’t say for how long, but recommended adding vitamin A (2,500 IU) and vitamin C (250 mg. 3x a day) as well as garlic, goldenseal, and propolis. He also listed some other products, but I think just ample amounts of colloidal silver and vitamin C should help. While I do fast my dogs, something about doing it to my cats bothers me.

      Years ago, before I knew about CS, one of my cats got an upper respiratory infection. I treated him with L-lysine and apple cider vinegar (ACV) and he cleared up in a few days. While Dr. Goldstein didn’t mention L-lysine, I really like to keep it on hand for when I notice someone sneezing more than a time or two. I also keep ACV on hand for numerous things, but I believe it may help you in this case as well. Dilute it 50/50 with water (CS is fine) and generously rub it on your cats. I like to do the paws and sides, where they can easily reach it to lick it off, thus ingesting it. Do that twice a day.

      I have also read that vitamin C is boosted by the use of MSM, so you may want to keep that in mind as well. Dr.’s Choice is a good brand and I like the ones with nothing but MSM in them. If they get a bit clumpy, all you have to do is shake the jar. The finer grit has added ingredients to prevent clumping and I avoid those.

      Hopefully, some of this information will you and your cats get back to good health soon.

      1. Thank you for all that great advice. We do use Lysene and apple cider vinegar, but there were a few others in your recommendation that I wasn’t doing. We have LOTS of cats (we’re on a farm, and strays just FIND us! They can apparently sniff out cat people from a great distance!). I don’t know if I can get stuff rubbed on all their paws. Could I add a little bit of ACV to their food? Does that throw off the taste too much? With the addition of any supplement, we kinda have to guess at the amount, and if anything, we are probably undercutting the recommended dosage, as we just add it to the large bowl of “soup” we serve at feeding time. It consists of soaked hard food, some smashed pate mixed in, a bit of pumpkin puree and a few peas, Missing Link, and the dissolved lysene, and then quite a bit of warm water to give them plenty of moisture. Do you think I can add the C and any other supplements to the same bowl, and just hope they get a reasonable dose of everything? It doesn’t seem possible feed everyone separately. The “soup” gets poured out onto about 8 large platters, and everyone comes and starts lapping away.

        1. Renate,

          Haha, I hear you about the animals “finding” you. I seem to have that attraction too. 🙂

          I’m not sure about adding the ACV to the food, or even water, as it’s awful stuff. You could try a little bit (capful?) and mix it in really well and see how they get along. If they are strays, my experience, with my own rescues anyway, is that they really aren’t that picky. If you have some sardines, tuna, or canned salmon (all in water), you could add that to the food, which could help mask the ACV taste and smell. Maybe slowly increasing the amount you add will help you if you have to start out in very small amounts.

          Another option is to put the ACV on their back between their shoulder blades, where it will be absorbed. I’ve personally never used that method, but I’ve read that it does work. Not sure that it would be much easier, as cats smell the ACV and tend to get leary around it, but there’s another possible method of getting it in them.

          As far as giving them amounts, I have seven cats that all eat randomly throughout the day. I just put my powders (L-lysine, liver powder, MSM, etc., etc.) in an old spice jar and shake it on their raw food as I prepare it and then stir it in before I put it into their bowls. Like you, there is no way I can make sure everyone gets the recommended dosage, so I spread it throughout. That has worked for me and I think it’s probably about the only way you can do it with so many cats. I’d check each vitamin individually, just to make sure you can’t harm a cat with them, but most things will go out the body through their waste if the body doesn’t need it. Not sure which ones, if any, are actually dangerous, but you might want to double-check that first before upping the doses too much.
