The Claim
Elevated serum vitamin B12 levels are associated with an increased risk of cardiovascular mortality, although the strength of this association is less consistent compared to the association between elevated serum vitamin B12 levels and all-cause mortality.
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.
People with higher levels of vitamin B12 in their blood seem to have a higher chance of dying from heart problems, but this link isn’t as clear as the link between high vitamin B12 and dying from any cause.
See the scientific wording
Elevated serum vitamin B12 levels are associated with increased cardiovascular mortality, though the evidence is less consistent than for all-cause mortality.
What the research says
1 studyThis study found that people with very high levels of vitamin B12 in their blood may be more likely to die from heart problems, but the link isn’t as strong or clear as it is for dying from any cause. So it mostly agrees with the claim.
