But that’s just a start… The longer you take Cardio Shield.. the better your results In fact, it usually takes 60 to 90 days to see optimal results, to make sure you optimize your blood pressure and stay there That’s why I personally recommend taking it for at least 180-days. Which is the 6-bottle option… So you can be stocked up and rest in full confidence knowing you won’t run out when you start seeing incredible, life-changing results.
