The vitamin B12 is not only important for the human body- it is also important to the health of a dog or cat’s nervous system and the growth of red and white blood cells. Lethargy, weakness in the legs, or a lack of appetite in a pet may be a result of a vitamin B12 deficiency. This common deficiency may be a result of insufficient levels of the vitamin in the pet’s diet, or of an inherited condition that makes it difficult or impossible for the pet to absorb it through its regular diet. A vitamin B12 deficiency that goes untreated may lead to more serious problems, such as serious gastrointestinal diseases and weight loss. A B12 vitamin supplement is a very effective and simple solution to the problem, whether the problem stems from insufficient dietary levels or from an inherited condition. B12 supplements can also help pets that suffer from gastrointestinal ailments or kidney disease.

How Long Until My Pet Shows Signs of Improvement?

The potential side effects of a B12 vitamin supplement are minimal. B12 is a safe, non-toxic vitamin. While it is possible for a pet to have too much of certain vitamin supplements, taking too much of a B12 supplement will very rarely harm the pet, because it is not stored in the body. The bloodstream will only absorb as much of the vitamin as it needs at a time, and discard the rest through urination. Vitamin B12 is truly a safe solution for pet lethargy, so talk to your veterinarian today about Vitamin B12 injections or supplements for your pet.
