How does a vegetarian diet impact serum cobalamin (vitamin B12) levels and cognitive function, particularly in terms of memory retention and fatigue in adults?
Abstract
Vegetarian diets often lead to lower serum cobalamin levels, potentially affecting cognitive function and causing fatigue. While some evidence suggests supplementation improves B12 deficiency, direct effects on cognition require further investigation.
