What Is Blue Spirulina?

Blue spirulina is a type of blue-green algae that grows in ponds, lakes, and alkaline water. Also known as phycocyanin, most people know it for its versatility and intense color.

Blue spirulina has several benefits, including:

Anti-Inflammatory Properties

Blue spirulina has compounds that have anti-inflammatory properties. The active component in Blue spirulina is called phycocyanin, which is a source of antioxidant substances that prevents inflammatory signaling molecules from being produced.

These molecules are what causes chronic inflammation in the body. Consuming Blue spirulina regularly will therefore alleviate symptoms that have to do with these chronic inflammatory conditions.

Antioxidant Properties

The phycocyanin in Blue spirulina also has powerful antioxidant properties that prevent many health conditions and diseases caused by oxidative stress. These are diseases like heart disease, blood pressure, arthritis, diabetes, and even cancer. Consuming foods that fight oxidative damage helps keep these conditions at bay.

Boosts the Immune System

Thanks to the presence of vitamins and minerals, Blue spirulina helps boost the immune system. Some of its vitamins include vitamins B6, E, and C. It has a high concentration of a pigment called zeaxanthin that reduces the risk of age-related loss of vision and cataracts. The antibacterial properties in Blue spirulina also help in maintaining good oral health by improving immune function.

Removes Heavy Metals

Spirulina can effectively bind heavy metals in the body, making them easier to eliminate. Phycocyanin, the compound that gives spirulina its distinctive blue-green color, also acts as a nitrogen storage molecule.

This nitrogen moiety plays an important role in heavy metal binding. This means that taking spirulina can help detoxify the body from heavy metals.

Can Help You Lose Weight

Blue spirulina is a source of vitamin B, which acts as a great energy booster. If you engage in any kind of physical activity, taking Blue Spirulina can give you the extra boost you need to perform at your best.

You can also burn fat faster, as Blue spirulina contains antioxidants that help minimize exercise-induced oxidative damage from exercise.
