DIRECTIONS FOR USE: Add 1/8th tsp. (1 scoop) and mix thoroughly into pet's canned, wet, or raw food meal daily for 30-90 days until symptoms resolve. May increase up to 1/4 tsp twice daily if your pet's symptoms are severe and resistant; but do not use for longer than 90 days.  If symptoms persist after the initial 90 day therapy, start your pet on ReNewedPet® Immune Boost II formula supplement powder for an additional 90 days until symptoms all resolve.

ReNewedPet® Liquid Pet Vitamin-C: is specially formulated to help support immune system health for dogs and cats. This formula is blended with pure MCT (medium chain triglycerides), naturally sourced from coconuts as well as 100% ascorbic acid (vitamin C) no additives or fillers. Our liquid C has been specially made to allow for the correct small dosages needed for pet safety unlike other products on the market made for humans which may have harmful additives and are labeled only for human dosages.

Vitamin C has been shown to be effective in aiding pets in many conditions including; chronic immune dysfunction, urinary tract disorders, skin health as well as an adjudicative treatment for pets fighting cancer. Many holistic veterinarians frequently utilize high-dose vitamin c like our liquid formula to bring new health to their patients.

Increase dose by 0.5 ml each day until your pet experiences "bowel tolerance" which will be evident by loose stool/diarrhea. At which point, you will decrease current dose by 1/2 and continue for an additional 1-2 weeks. Repeat as needed during times of illness or stress only, not for daily use long term.

Ingredients: non-gmo mct oil, ascorbic acid.

This helped my babies through a nasty cold

All 3 of my cats came down with a nasty URI. It was pretty brutal on them and it hung on for weeks. In conjunction with some other meds, I got them on this and the immune boost powder and after a few days it seemed like they finally turned the corner. I really think this contributed to their recovery and I plan to keep it on hand just in case! I'm so happy to have Renewed Pet products in my life and love that these are thoughtfully made with clean ingredients!

Great Stuff

Great product to add some vitamins to your cats diet. I feel it really helps my cats overall immune system!

Great product

Just started my kitten on these to help boost her immune system from being on several antibiotics related to her clogged tear duct. Pleased with the products :)

I started my kitties on the immune boost 1 along with the liposomal vitamin c, and I am so excited how much renewed energy and vigor my 6 month old kitty has now. He was recently treated for mycoplasmosis, as well as a corneal sequestrum, and the regimen he was on really knocked his poor body down. His eye requires surgery soon, so I wanted to build his resistance back up, and boy did these products work. So excited!! Definitely recommend!!!
