The Claim
Dietary supplementation with antioxidants (vitamin E, vitamin C, beta-carotene) and B vitamins (folate, B6, B12) does not consistently prevent coronary heart disease events or mortality, and may increase risk in some cases, despite observed associations between these nutrients and reduced heart disease risk.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking vitamin pills like E, C, and B vitamins doesn't reliably help prevent heart attacks or save lives from heart disease—and in some cases, they might even make things worse—even though people who eat more of these vitamins often seem to have healthier hearts.
See the scientific wording
Dietary supplementation with antioxidants (vitamin E, vitamin C, beta-carotene) and B vitamins (folate, B6, B12) shows no consistent benefit in preventing coronary heart disease events or mortality, and may even increase risk in some cases, despite observational associations.
What the research says
1 studyStudy: Coronary heart disease prevention: nutrients, foods, and dietary patterns.
The study says taking vitamin pills like E, C, or B vitamins doesn’t reliably prevent heart disease and might even be harmful, which matches the claim that these supplements don’t work and could be risky.
