Rated 3 out of 5 by from Photo of bucket misleading You can’t order the bucket pictured. For the $38.95 you get a small jar size container that you can hold on the palm of your hand. I think this used to be sold for quite a bit less, like $14. I don’t know if it’s an error in the system but it’s really overpriced

Rated 5 out of 5 by from My veterinarian told me to put my mare on 5000+ mg of Vitamin C because it would help increase the efficacy of one of her meds. She's normally a picky eater, but absolutely loved this product for the 90 days she needed it. I also appreciate the fact that it was priced affordably. Overall, I would recommend this product.

Rated 5 out of 5 by from Helps my respiratory guy! This is the perfect supplement for my respiratory horse. We tried many things and decided to take a chance on this one and now its all we need! No more albuterol! Was not recommended by anyone, just a shot in the dark that happened to work. Give it a shot!!

Rated 4 out of 5 by from Helps my hot mess of a mare **This is not veterinary advice** I recently got a mare with some major problems. She had cancer in her third eyelid which we had removed. She also has an Ethmoid Hematoma which causes her to have nosebleeds. My vet and I both weighed out pros an cons of a major surgery and I ultimately decided against it but want to make my mare as comfortable as possible for the remainder of her days. I read somewhere that Vitamin C was the best choice for horses with runny eyes and or runny noses so I figured I'd give it a shot considering she has major issues in both. Her eye recovery was fantastic, very minimal discharge, healed in 2 weeks after surgery. Her nosebleeds have reduced SO MUCH! I know this is not going to solve her problem with her Ethmoid hematoma BUT the bleeding is very minimal now. I will keep her on this for the rest of her life. it took about two weeks to start seeing a difference. NO, this is not an alternative to vet attention. This is simply in hopes to help someone else in my situation.

Rated 5 out of 5 by from Horse seems to like it and I think it helped him I bought this because my horse started to have some nasal discharge again. He had the same thing last year and it eventually cleared up by itself (the vet did not want to give antibiotics) so I decided to try giving him some Vit. C to see if it would help. It seems to have already cleared up, much faster than last year! Of course I cannot say with 100% certainty that it was the C that helped him but then again maybe it was. At any rate, he ate it with no problem and he is doing well now.

Rated 5 out of 5 by from Boosts immunity After surgery and being on antibiotics for 10 days this fall my mare started to get a runny nose and eyes. Probably due to her immune system being challenged from the surgery, stress and antibiotics decreasing her natural ability to fight crud. After a few days of vitamin C she cleared up, perked up and is looking great. Will keep her on it at least over the winter and put her back on next winter. Great product.
