The Claim
In pigs, the consumption of synthetic cyanocobalamin within a plant-based meal matrix does not result in measurable intestinal absorption, as indicated by net portal-drained viscera flux values that do not differ from zero or from those observed with an unsupplemented control meal.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When pigs eat a plant-based meal with synthetic B12 (cyanocobalamin), their bodies don't seem to absorb it — there's no measurable amount showing up in their gut system compared to a meal without it.
See the scientific wording
Synthetic cyanocobalamin, when consumed in a plant-based meal matrix, is not associated with measurable intestinal absorption in pigs, as net portal-drained viscera flux did not differ from zero or from an unsupplemented control meal.
What the research says
1 studyStudy: Bioavailability of vitamin B12 in cows' milk
The study gave pigs meals with synthetic B12 and found their bodies didn’t absorb it, just like the claim says.
