 Health Benefits of Spirulina

Spirulina has various nutrients that boost the body’s physical wellness. The most important benefits of blue spirulina to the body are believed to be:

Weight Loss Aid

Blue spirulina is rich in protein content. If you consume it before taking meals, it makes you feel fuller, which cuts the amount of food that you will consume. In addition, people with morbid or borderline obesity can take it and use it as a means of lowering their food consumption and, consequently, weight loss.

Source of protein

Spirulina has 67% protein content. It is a beneficial source of essential amino acids for people on a vegan diet.

Vegan powder extracted from plants lacks the amino acids present in blue spirulina. A vegan should take blue spirulina to compensate for that protein shortage.


Spirulina has extremely high levels of oxidants that bind heavy metals and aid their excretion. The process cleanses the body and improves wellness. The high level of oxidants present in spirulina has an anti-inflammatory impact on the body. High levels of oxidants in the human body promote inflammation and the development of cancer cells.

Blue spirulina is rich in protein, vitamins, minerals, iron, carotenoids, and antioxidants that may help protect cells from damage.

Spirulina also contains phycocyanin, which reduces inflammation, blocks tumor development, and eliminates cancer cells; therefore, spirulina has anti-cancer properties.

Stimulates Energy Levels

Blue spirulina is full of Vitamin B, and it largely boosts energy levels, especially for those that are physically active. Vitamin B12 is among blue spirulina’s primary nutrients, and it’s the most essential nutrient for body survival. It aids your gut and brain health. Therefore, the supplement is quite useful in supplementing a vegan’s diet.

Spirulina's antioxidant content makes it beneficial in decreasing exercise-induced oxidation, which leads to muscle fatigue and the inability to gain muscle.

Improves Bowel Movement and Bowel Health

Blue spirulina has chlorophyll that helps in the modulation of the digestive system, especially bowel movement and health. Spirulina also promotes the development of good bacteria in the human gut. Individuals with frequent digestive issues can improve their health outcomes by taking spirulina in their daily food or as supplements.

Blood Pressure Modulation

Spirulina increases nitric oxide production in your body, which helps your blood vessels relax. This can reduce your blood pressure, lowering your risk of heart disease.

Promotes good oral health and reduces oral cancer

Its antibacterial properties may also help promote good oral health. One study found that spirulina-enhanced mouthwash reduced dental plaque and the risk of gingivitis in participants (1). Another study showed it lowered the risk of oral cancer in people who chew tobacco (2).

Today, spirulina continues to be one of the popular supplements owing to its rich nutritional value.

Most food stores have blue spirulina powder. Blue spirulina has an electric blue color that allures your attention and appetite.
