Imagine a supplement powerful enough to help shield your heart from the silent killer known as high blood pressure. That's the promise of spirulina, a blue-green algae with centuries-old roots in nutrition, now gaining modern scientific backing for its potential to lower blood pressure and reduce the risk of strokes and heart attacks. Beyond its vibrant color and earthy taste, spirulina packs a punch of proteins, antioxidants, and heart-healthy compounds — making it an unexpected ally in the battle against hypertension.

A recent study found that taking 3 grams of spirulina daily for at least 12 weeks significantly lowers blood pressure — potentially reducing cardiovascular risks.
