Methodology
Meta-analysis of 15 randomized controlled trials of flaxseed products on systolic and diastolic blood pressure.
Key Findings
Flaxseed supplementation significantly reduced diastolic blood pressure (-1.3 mmHg); systolic reduction reached significance only in trials of at least 12 weeks with whole flaxseed.
Conclusions
Flaxseed produces small blood pressure reductions, mainly with longer-duration whole-seed use.
Limitations
Small effect size, heterogeneity across preparations, few trials of flaxseed oil alone.
Supplements Studied
Flaxseed supplementation significantly reduced diastolic blood pressure; systolic reductions were significant only in trials lasting 12 weeks or longer.
Outcomes Measured
Flaxseed supplementation significantly reduced diastolic blood pressure; systolic effects required 12 weeks or more.
