Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
Yes — when a cat has low cobalamin, also known as vitamin B12, supplementation can help restore healthy levels. Cobalamin is especially relevant for cats with intestinal or pancreatic conditions that interfere with nutrient absorption. It is not a substitute for veterinary diagnosis or treatment.
Cobalamin does not treat or cure kidney disease. However, cats with CKD may also experience poor appetite, weight loss, vomiting, or other health issues, so your veterinarian may recommend testing or supplementation based on your cat’s individual needs. Always check with your vet before adding a supplement to a kidney-care plan.
Yes, when the vomiting is connected to low B12 or an underlying intestinal or pancreatic condition. Cobalamin deficiency is associated with vomiting, poor appetite, diarrhea, weight loss, and an unhealthy coat. Recurring vomiting still requires veterinary evaluation to identify the cause.
Cat food contains B12, but a cat with poor absorption may not receive enough of it—even from a complete diet. Mizu Labs Cobalamin provides a direct, measured supplemental source to help maintain adequate B12 intake.
You are covered by our 60 day money back guarantee. That gives you a full 2 months to take it consistently and track your own results. If you are not satisfied for any reason, contact us and we will refund you. No hassle. We built it this way because olive leaf needs real time to do its work, and we would rather you judge it on the full experience than a single week.
Give it according to the serving instructions on the Mizu Labs label. Consistent use is important because cobalamin support works best when it is given on the recommended schedule. Cats being treated for a confirmed deficiency should follow their veterinarian’s dosing plan.
