These Supplements Lower Blood Pressure (Doctor Explains)

Supplements Discussed for Blood Pressure

Dr. Ashley Froese discusses five supplements that may support lower blood pressure. She emphasizes that supplements are not a substitute for medical care and may be considered alongside diet and exercise changes, particularly when blood pressure is borderline.

Beetroot Juice or Powder

Beets contain nitrates, which the body converts into nitric oxide. This may help relax blood vessels. Dr. Froese says studies have found blood-pressure reductions of about 5–10 points.

She suggests 250 ml of juice or 1–2 teaspoons of powder once daily. People prone to kidney stones should use caution because beets contain oxalates.

L-Citrulline and L-Arginine

These amino acids may support nitric oxide production and blood-vessel relaxation. Dr. Froese suggests about 6 g of each daily and says they may be especially useful for people with metabolic syndrome.

Magnesium

Magnesium may help relax blood vessels and reduce stress-related blood-pressure spikes. Dr. Froese suggests 300–500 mg, mentioning glycinate or threonate as forms to consider, preferably taken at night.

She also shares that these forms gave her vivid, unpleasant dreams, despite noticing lower blood pressure the following day.

Coenzyme Q10 (CoQ10)

CoQ10 supports cellular energy production. Dr. Froese says studies suggest it may lower systolic pressure by around 10 points and suggests 100–300 mg.

People taking statins such as atorvastatin or rosuvastatin may want to ask their clinician about CoQ10.

Ayurvedic Herbal Blend

The subtitle appears to identify the blend as “cardboard.” It is described as containing rauwolfia and arjuna. Dr. Froese says some patients report benefits, but warns that the blend can be potent and is not suitable for everyone. She recommends using it only with blood-pressure monitoring and a doctor’s guidance.

Safety Note

Consult a doctor before using supplements. Do not stop or replace prescribed blood-pressure medication without guidance from a healthcare provider. Diet and exercise changes are also important parts of blood-pressure management.
