Can Your Diet Lead to Vitamin B12 Deficiency?
Published: Jan 03, 2024
Your diet might be putting you at risk for vitamin B12 deficiency. Learn how dietary choices can impact your vitamin B12 levels and what you can do about it.
Vegan and Vegetarian Diets
Vitamin B12 is found mostly in animal-based products, so those following vegan or vegetarian diets may not get enough. To avoid deficiency, these individuals should consider taking vitamin B12 supplements, especially important for pregnant women to ensure their developing fetus gets enough vitamin B12.
Gastric Surgery and Absorption Issues
People who have undergone gastric surgery can have reduced levels of intrinsic factor, a necessary component for vitamin B12 absorption. This can lead to deficiency, and supplementation is often required to maintain adequate levels. Monitoring and consultation with healthcare professionals are advised.
