What's included in this test?
Vitamin B12
Vitamin B12 plays a critical role in the production of red blood cells, which carry oxygen throughout the body. It also supports metabolism and the nervous system, and prolonged deficiency of vitamin B12 may lead to nerve damage. While vitamin B12 is predominantly present in animal-based foods, some vegetarian and vegan products, such as plant-based milks, are now fortified with this vitamin.
Vitamin B9 (Folate)
