The Claim

Among adults with type 2 diabetes, serum folate levels above 19.5 ng/mL are not associated with an increased risk of cardiovascular disease mortality compared to serum folate levels between 7.1 and 12.1 ng/mL, indicating that elevated folate levels do not elevate mortality risk from cardiovascular disease in this population.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

For people with type 2 diabetes, having higher levels of folate (a B vitamin) in their blood doesn’t seem to make them more likely to die from heart disease, compared to people with moderate folate levels.

See the scientific wording

Among adults with type 2 diabetes, serum folate levels above 19.5 ng/mL are not associated with increased cardiovascular disease mortality risk compared to moderate levels (7.1–12.1 ng/mL), suggesting that high folate does not increase risk in this population.

What the research says

1 study
  1. Study: Associations of Serum Folate and Vitamin B12 Levels With Cardiovascular Disease Mortality Among Patients With Type 2 Diabetes

    This study found that adults with type 2 diabetes who have high levels of folate (above 19.5 ng/mL) don’t have a higher chance of dying from heart disease compared to those with moderate levels — so high folate isn’t harmful in this group.
