Hypertension Canada breaks down blood pressure categories and the appropriate recommendations as follows:

How do I Take PreCardix®?

PreCardix® is easy to add to your blood pressure management plan. Get started by knowing your baseline blood pressure levels. Review your results with your health care provider to make sure your treatment plan is safe and appropriate! 

Step 1. Measure and record baseline blood pressure.

Step 2. Take two (2) PreCardix® tablets together each day for eight weeks (2 packs). 

Step 3. Measure and record blood pressure weekly.

Step 4. Compare baseline to results after eight weeks.

Step 5. Continue to take PreCardix® daily to maintain results. 

Step 6. Continue to measure and monitor your blood pressure regularly. 


How soon should an effect on blood pressure health be expected after starting PreCardix®?

In clinical trials, 89% of participants experienced a significant effect on blood pressure health within two to eight weeks. Take PreCardix® for at least eight weeks (2 packs) before determining if it works for you. 


How much of an effect on blood pressure health is expected after starting PreCardix®?

In the clinical study, the average improvement in blood pressure was 6.7 mmHg in systolic blood pressure and 1.7 mmHg in diastolic blood pressure within 8 weeks2. These results are compared to baseline blood pressure (participants’ blood pressure before introducing PreCardix®). Furthermore, 43% of participants improved their systolic blood pressure greater than 10 mmHg, and 24% had an improvement of over 15 mmHg in systolic blood pressure.
