What is high blood pressure?

Hypertension is the medical term used to describe high blood pressure. Blood pressure is the force of the blood pumped from the heart against the blood vessels. This force makes blood flow possible, delivering nutrients and oxygen to organs and tissues throughout the body.

Hypertension occurs when there is too much pressure in your blood vessels. This can damage your blood vessels and cause health problems. Anyone can develop high blood pressure, but it becomes more common as you get older.

Know your numbers

The first step in understanding high blood pressure is learning what your numbers mean. Blood pressure is measured with two numbers: systolic (the higher number) and diastolic (the lower number) (e.g., 120/80 mmHg):

  • Systolic pressure occurs when your heart contracts.
  • Diastolic pressure occurs when your heart relaxes and fills with blood.
  • Blood pressure is measured using millimetres of mercury (mmHg), which is a standardized measurement of pressure.

The higher your systolic or diastolic blood pressure – and the longer it stays high – the greater the potential damage to your blood vessels. For many people high blood pressure can be managed by leading a healthy, active lifestyle. If you are having difficulty managing blood pressure PreCardix may help.

PreCardix is clinically proven to support healthy blood pressure, safely and effectively

PreCardix is the result of over a decade of blood pressure research and clinical study dedicated to finding an effective, sustainable and proven natural blood pressure solution.

Clinical Trial Highlights

  • 89% of clinical trial participants experienced significant effects by 8 weeks
  • 69% of clinical trial participants improved their blood pressure by over 10mmHg in 8 weeks
  • 24% of clinical trial participants improved their blood pressure by over 15mmHg within 8 weeks

Clinical Trial Details

Two clinical studies Marealis 13TBHM and Mare-study were conducted on PreCardix between 2012 and 2015 with over two hundred and twenty male and female participants ages 30 – 75. Clinical results show that the bioactive marine peptides in PreCardix have a clinically documented ACE inhibiting action, resulting in significant effects in blood pressure health in over 89% of participants within eight weeks or less.

89% experienced significant effects in their blood pressure health within 8 weeks.

Blood pressure improvement

The proven and natural blood pressure lowering effect of PreCardix is comparable to common antihypertensive drugs. No side effects were documented during either study.

How does PreCardix work?

Natural ACE Inhibitor

ACE inhibitors help lower blood pressure by preventing ACE (the angiotensin converting enzyme) from converting angiotensin 1 to angiotensin 2. This preventative action reduces the risk of developing cardiovascular conditions such as high blood pressure. PreCardix is a clinically proven natural ACE inhibitor.

Contains unique bioactive marine peptides

PreCardix contains a unique refined shrimp peptide concentrate (Marealis RSPC). This unique peptide concentrate is derived from the proteins of fresh, cold water Arctic prawns (Pandalus Borealis) through a controlled enzymatic hydrolysis process. Enzymatic hydrolysis breaks down larger protein chains into smaller, peptide chains. These peptide chains are further refined into Marealis RSPC through a proprietary process resulting in a clinically proven bioactive peptide with an ACE inhibiting effect.


Medical ingredients (amount per tablet): Shrimp protein hydrolysate (Pandalus Borealis – shell): 600 mg

Non-Medical Ingredients: microcrystalline cellulose, croscarmellose sodium, magnesium stearate, silicon dioxide, polyethylene glycol, USP-NF talc, polyvinyl alcohol, titanium dioxide.

Take 2 tablets together daily before noon, a few hours before or after medications, natural health products, or food. Allow 8 weeks to achieve results and continue to take daily to maintain results.
Consult with your health care provider before making changes to your blood pressure management plan. 

No significant side effects documented during clinical study

PreCardix does not have any known significant side effects. It does not cause side effects sometimes associated with ACE inhibitor medication such as dry cough, itching, edema (swelling), high potassium levels, or hypotension (low blood pressure). 

PreCardix may cause moderate nausea. One case of mild; euphoric mood, fatigue, upper abdominal pain, and headache occurred during the clinical trial. 

Sustainable source

PreCardix bioactive marine peptides are derived from sustainable cold water prawns from the Arctic sea. Pandalus Borealis (wild Arctic prawns) are harvested by PreCardix founders, Stella Polaris. Stella Polaris is one of the world’s leading producers of cold water prawns. Stella Polaris is BRC (British Retail Consortium) and DNV certified. BRC is one of the world’s most demanding quality standards for food production. Stella Polaris is also MSC (Marine Stewardship Council) and KRAV certified. KRAV certified companies are dedicated to economically, organically and socially sustainable food production without compromising the ability of future generations to meet their own needs. This long history of commitment to sustainable practices ultimately inspired Stella Polaris invest significantly in PreCardix.
