Rx Vitamins Bio-C Powder Immune Supplement for Cats & Dogs, 4-oz bottle

Good stuff

I bought this to help keep my little toothless, FIV positive boy healthy. He is an outdoor cat except at night and in the winter when he comes into the garage with his Mama and his little friend. Because all his teeth were removed he is at risk for bacteria in his mouth. So far he seems to have quite a bit of pep in his step..I would recommend if you have a pet with a compromised system. And it must not have a taste at all - he never notices it in his food.

We like just about all the products from Chewy. Do you ever send coupons that returning customers can use. I get coupons for first time buyers about once a month. You can only be a first time buyer once.

Joint care

Just started the product.

Better than on-time delivery with a good product.

Talk about speedy customer service! Chewey is always prompt but this order came in day. Bravo! The vitamin C for our dogs is effective and helpful.

Works for my cats

I have a cat with herpesvirus whose tendency is upper respiratory infections on a bad day and vicious snotballs on a good day. We've tried about every bandaid treatment recommended by the vet, and undecided to try this out because Vit C helped my health. Yall, this stuff is amazing. He sneezes way less often, and his mucus production is way down. No URI's since he started it. He cant detect any flavor when mixed with wet food, so he takes it well. Overall, I highly recommend

Just keeps getting better

I had to buy this for my cat who has a whole host of GI issues, bladder crystals being one of them. The product has reduced the crystals in his bladder, has helped increase his thirst so he drinks more water (crucial in cats), and I believe has helped calm his tummy down. They've even improved the taste over the last couple months without losing the effectiveness of the product. I can't say enough good about it. Thank you!

Bought for Urinary Tract Health

I think this is a good quality product - bioflavinoids are great antioxidants and this was something recommended for me to use while treating my dog for a bladder stone. Unfortunately he doesn't like the taste of it mixed with either his food or his favorite treat - sour cream!

Excellent Product

Bio-C is an excellent way to get Vitamin C into my two dogs. It became extremely valuable when the entire household had COVID19. My two were sick but not as sick as they could have been or would have been. I keep them both on Bio-C to keep their immune systems functioning well.

Bladder crystals gone!

After one month of applying powder on kibble twice a day, my dogs stubborn bladder crystals are finally gone! As an added benefit, not that he had elevated counts but my dog's liver looked much better on ultrasound. Totally recommend!

Fantastic supplement for recovering or ill dog

Our vet said even though dogs make their own vitamin C, at times of physical stress or fighting infections, they may not make as much as they need. We add Bio-C to our 8 yr old and 14 yr old dogs' food whenever they are sick or were recovering from surgery. A powerful antioxident, Bio-C was well tolerated (no spit up), and really makes a difference to how they're feeling and how they recover. My vet even has us add it (as well as Proviable) when the dogs are on antibiotics.
