Vitamin B12 presented by Professor David Cameron-Smith
What it is & what it does: essential functions and health effects
Jump in for a refresher on Vitamin B12. Professor David Cameron-Smith provides an overview of the biology of vitamin B12: despite it having just one role in two pathways it has a profound impact on human health through energy metabolism and DNA synthesis. Shifting to clinical insights, we review digestion, deficiency, and supplementation. For our nutrition nerds (we know you are out there!) this might be a reminder of what brought you to the world of dietetics. Enjoy!
Learn about:
- The primary sources of Vitamin B12 (there’s not as many as you think) and how it shows up in other sources in our food system.
- Why active B12 provides a more accurate picture of status, particularly in older adults or those with non-specific neurological symptoms.
- Two absorption pathways (facilitated transport mechanism vs passive diffusion) and how this informs supplement dose.
