How long for Tumil-K to fix low potassium and improve pet appetite?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 19 years and 8 months old | 9.5 lbs

Hi Tony’s potassium level was low in his last lab results on August 28th so on August 30th my vet had me increase his tumil k dosage. I was told low potassium can cause lack of appetite which tony is experiencing and it’s just been about 10 Days since the increase In tumil k. About how long would it take for the new dosage of tumil k to correct his low potassium level Because his appetite is still very off. Thank you!

Your vet will likely recommend to recheck the potassium level within the next 2-4 days. By this point, the supplement should have taken effect. It is important to make sure the levels are normal. It's possible to low appetite is not related to the potassium level. If the levels are normal but his appetite is still low, then you know it's related to something else. I recommend to call your vet today and have Tony scheduled for the bloodwork. I hope this helps and please feel free to post any additional questions.

    Generally the effects will be noticed quickly (within 7-10 days). This does depend though on how low Tony was to start with and there is variability between individual responses. I recommend to call your vet today and update them. They will be able to give you a better idea of a time frame. It's also possible that the low potassium is not the cause of his illness. The vet may also consider other diagnostics. I hope this helps and please feel free to post any additional questions.
