Outcome of Vitamin B12 Deficiency: Homocysteinemia and Megaloblastic Anemia
Tuesday, 7 April, 2026
This podcast transcript explains how a **vitamin B12 deficiency** disrupts the essential recycling of **folate** within the body. When B12 levels are insufficient, folate becomes permanently stuck in its **methylated form**, a phenomenon often referred to as the **folate trap**. This chemical blockage prevents the creation of other active folate types necessary for **DNA synthesis** and amino acid processing. Consequently, the lack of these vital compounds leads to serious health issues such as **megaloblastic anemia** and a buildup of **homocysteine**. To effectively resolve these metabolic imbalances, medical professionals typically recommend a combination of **B12 and folic acid supplements**.
