The Best Supplements For High Blood Pressure

High blood pressure affects about 1 in 4 Canadians, with an even higher prevalence in the United States.

From the dietary perspective there are two overarching areas to consider when trying to reduce your blood pressure.

  1. Increase Your Potassium, Magnesium, Calcium & Fibre intake
  2. Reduce Your Sodium Intake

The goal of today’s article is to offer forward a brief overview of the potential blood pressure lowering effects of commonly available supplements.

To ensure safe use of any supplement, it is strongly advisable to first consult with your healthcare provider.

Omega 3s

A recently published meta-analysis out of the  Journal Of The American Heart Association found that Omega-3 supplements containing 2-3 grams of DHA/EPA per day could lower both systolic (~ 2.6 points)  and diastolic blood pressure ( ~1.7 points) over a multi-month period.

These types of omega-3 fatty acids are also found in rich supply in salmon, sardines, mackerel, trout and herring.


A 2017 meta-analysis out of the American Journal Of Clinical Nutrition determined that magnesium supplementation in the 350-450 mg per day range, over a multi-month period, could reduce systolic blood pressure (~4 points) and diastolic blood pressure ( ~2.25 points) over a multi-month period.

Most people don’t eat enough magnesium, learn more about magnesium-rich foods here.


A meta-analysis published in the Journal Of Human Hypertension found that calcium supplementation around ~1200mg daily over a multi-month period reduced systolic blood pressure ( ~1.86 points) and diastolic blood pressure ( ~.99 points) over a multi-month period.

The blood pressure lowering effects of calcium supplementation was about ~50% higher in those with low dietary calcium intake.

Potassium & Fibre

Potassium and fibre are fundamental to good health and blood pressure lowering, they are found grouped together in large amounts in six families of foods.
