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 lower 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 a significant blood pressure lowering effect within 8 weeks
  • 69% of clinical trial participants reduced their blood pressure by over 10mmHg in 8 weeks
  • 24% of clinical trial participants reduced 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 natural ACE inhibiting effect on the body resulting in a significant blood pressure reduction in over 89% of participants within eight weeks or less.

89% experienced a significant blood pressure lowering effect in 8 weeks.

Blood pressure reduction

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.

Visit our FAQ section for additional information about PreCardix ingredients.


Take 2 tablets together with water each morning. Results may take up to 8 weeks. PreCardix must be taken daily to maintain its blood pressure lowering effect.

No serious side effects documented during clinical study

PreCardix® has not been found to cause side effects sometimes associated with common ACE inhibitor medications such as dry cough, itching, edema, high potassium levels, or hypotension.

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.


PreCardix is currently undergoing non-gmo third-party verification. Certification will be completed prior to 2020.
