If your dog or cat struggles with digestive issues or simply needs an energy pick‑me‑up, vitamin B12 is often part of the plan. Until now that meant a monthly trip to the clinic for a shot (and all the stress that comes with it). Rx B12 flips the script with a tasty liquid you can give at home in seconds.
Why pets—and their people—love it
-
Goodbye needles, hello spoon‑licks. One quick squeeze of the dropper over food or straight into the mouth, and you’re done. Most pets lap it up thanks to the gentle, savory flavor.
-
Daily support that really works. Studies show an oral dose each day raises B12 levels just as reliably as monthly injections, keeping digestion, appetite, and overall vitality on track.
-
Budget‑friendly sizing. A single 4 fl oz (120 ml) bottle lasts about 30 days for a 60‑lb dog and up to four months for a 10‑lb cat, so you’re getting serious mileage for your money.
