Vitamin B12 is a vital nutrient that plays a crucial role in several essential bodily functions. It supports the production of red blood cells and DNA, aids in maintaining brain health, contributes to energy metabolism, and encourages healthy nerve function.

The recommended daily value (DV) for adults is approximately 2.4 micrograms (mcg). This daily intake increases slightly for pregnant individuals to 2.6 mcg and for those who are breastfeeding to 2.8 mcg.

While most individuals can meet their B12 requirements through a balanced diet, certain groups, such as those with restricted diets or absorption issues, may benefit from supplements.

Vitamin B12 Supplements: What to Know

Beyond dietary sources, vitamin B12 is available in supplements, including B-complex supplements, multivitamin or multimineral supplements, and standalone B12 tablets.

Dosages can vary widely, with some supplements offering up to 1,000 mcg of the vitamin, though the body absorbs only a limited amount at a time.

It is important to consult a healthcare provider before taking vitamin B12 supplements, as they may interact with certain medications, including gastric acid inhibitorsand metformin.

Vegetarians and vegans face a higher risk of vitamin B12 deficiency because the vitamin is primarily found in animal products.

However, several non-meat options can help meet B12 needs. These include dairy products, eggs (for vegetarians), fortified foods, nutritional yeast, and certain seaweeds.
