While kelp and seaweed may be the first types that come to mind, spirulina is a non-seaweed, single-cell algae that also falls into this category. Spirulina is a type of bacteria called cyanobacterium, which is often referred to as blue-green algae, and it is a bona fide superfood. These algae contain antioxidants, vitamins, minerals, and other nutrients and have been used as a food supplement for years. Spirulina is full of nutrients that are essential to keeping our bodies functioning the way they’re supposed to.* You can get all of these nutrients from other sources, of course, but spirulina, as a one-stop shop for so many of them at once, is the kind of substance the word “superfood” is meant to describe. Spirulina’s antioxidant properties are attributable to a substance called phycocyanin6.* In addition to boasting antioxidant properties7, phycocyanin8 is also responsible for giving spirulina its vibrant blue-green color.* Oxidative stress (also known as oxidative damage) can wreak havoc on fatty structures in the body. Because spirulina is such a powerful antioxidant, it can help to prevent LDL (low-density lipoprotein—the “bad” cholesterol) from becoming oxidized9.* Researchers believe these benefits are thanks to spirulina’s positive impact on the body’s production of nitric oxide, which helps blood vessels relax and dilate, thereby allowing blood to flow more quickly and easily.* Overall, spirulina definitely earns its reputation as a superfood, and any way you decide to take it has the potential to help support your health across the board.
