The Claim
In pigs, intestinal absorption of vitamin B12 from cows' milk results in significantly greater net flux of vitamin B12 across the portal-drained viscera over 24 hours compared to equivalent amounts of synthetic cyanocobalamin, with measured cumulative flux ranging from 5.5 to 6.8 μg and absorption efficiency between 8% and 10%, whereas no measurable net absorption of vitamin B12 was observed with synthetic cyanocobalamin or unsupplemented meals.
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.
Pigs absorb way more vitamin B12 from cow's milk than from a lab-made version, and they don’t absorb the lab version at all — their bodies only seem to take in the natural kind.
See the scientific wording
In pigs, intestinal absorption of vitamin B12 from cows' milk is associated with significantly greater net flux across the portal-drained viscera compared to equivalent amounts of synthetic cyanocobalamin, with cumulative 24-hour fluxes ranging from 5.5 to 6.8 μg and absorption efficiency between 8% and 10%, while no measurable net absorption occurred with cyanocobalamin or unsupplemented meals.
What the research says
1 studyStudy: Bioavailability of vitamin B12 in cows' milk
The study found that pigs absorb much more vitamin B12 from real milk than from synthetic supplements, and the numbers match exactly what the claim says.
