Benefits of spirulina

Spirulina is a super food due to its multiple potential health benefits. A study review in 2018 shows that spirulina can help improve health markers such as lipid, glucose, and diastolic blood pressure (3).

Also, a 2020 study review reveals that spirulina may help reduce body fat, waist circumference, body mass index and appetite (4). Not to mention that spirulina may help improve blood lipids.

How to eat spirulina

The taste of spirulina on its own can have a subtle savory sea vegetable flavor which may not be pleasing to the palate for some on its own (5). Therefore, you’ll often find it in recipes that contain lots of fruit and fruit juices to provide the spirulina health benefits while masking the flavor.

One spirulina recipe you can try that is quick and easy is this fruity spirulina smoothie. Follow the steps below for a delicious superfood beverage to add to your routine today.
