How Flaxseed Helps with High Blood Pressure
Flaxseed contains alpha-linolenic acid (ALA), lignans, and fiber that work together to reduce blood pressure. It's one of the most potent natural foods for BP reduction.
🔬 What the Research Says
A landmark 2013 study in Hypertension (AHA) found 30g/day of ground flaxseed reduced systolic BP by 10 mmHg and diastolic by 7 mmHg over 6 months - one of the most potent dietary interventions ever studied for BP.
