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.

Seems to help, but cats don't like to eat it

Always difficult to give vitamins to cats, but mine needed Vitamin C. I bought this in the hopes they would like the flavor, but they didn't. I have to mix some of the powder with water (it doesn't dissolve well), put this into a syringe, and squirt it in the back of their throat. They don't like it, but they tolerate it. No barfing. And it is definitely helping them, so I am glad that I bought it for them.
