Vitamin B12 Overview
Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.

Vinblastine is used in combination with other chemotherapy drugs to treat Hodgkin's lymphoma (Hodgkin's disease) and non-Hodgkin's lymphoma (types of cancer that begin in a type of white blood cell that normally fights infection), and cancer of the testicles. It is also used to treat Langerhans cell histiocytosis (histiocytosis X; Letterer-Siwe disease; a condition in which too many of a certain type of white blood cell grows in parts of the body). It may also be used to treat breast cancer that has not improved after treatment with other medications and gestational trophoblastic tumors (a type of tumor that forms inside a woman's uterus while she is pregnant) that has not improved after surgery or treatment with other medications. Vinblastine is in a class of medications called vinca alkaloids. It works by slowing or stopping the growth of cancer cells in your body.
