Understanding The Research Based Benefits of Spirulina

Spirulina, made from organisms that grow in both freshwater and saltwater, is one of the most popular dietary supplements around the world.

Today, people use spirulina to increase the levels of nutrients and antioxidants in the body, which helps protect against various diseases.

What is Spirulina?

Spirulina is a microscopic and filamentous cyanobacterium, a family of single-celled microorganisms often called blue-green algae.

It has been used as food since ancient times, and it is reported that it was even used during the Aztec civilization. This algae is an important staple food for humans and has been used by humans as a source of protein and vitamins without serious side effects.

Research-Based Health Benefits of Spirulina

Heart Health

Spirulina supplements can help significantly lower total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides. This keeps your arteries clean and reduces the strain on your heart, which can lead to blood clots that can lead to heart disease and stroke. Another study points out that blue-green algae like spirulina may be an effective natural option for improving blood lipid profiles, preventing inflammation and oxidative stress, and protecting against cardiovascular disease.

Anti-Cancer Properties

The many antioxidants found in Spirulina have anti-inflammatory properties in the body. Chronic inflammation contributes to the development of cancer and other diseases. Phycocyanin, the plant pigment that gives spirulina its blue-green colour, has been shown to not only reduce inflammation in the body but also to stop tumour growth and kill cancer cells.

Allergy Relief

The anti-inflammatory effects of Spirulina's antioxidants help people with allergies to pollen, animal dander, and dust. One study found that participants experienced significant reductions in symptoms such as nasal congestion, sneezing, and itching, suggesting that spirulina may be a good alternative to allergy medications.

Immune System Support

Spirulina is rich in many vitamins and minerals that are essential to maintaining a healthy immune system, including Vitamins B, E, C, and B6. A research-based study has shown that spirulina helps in increasing the creation of white blood cells and antibodies that fight viruses and bacteria in the body.

Eye and Oral Health

Spirulina is rich in antioxidants such as beta-carotene and zeaxanthin. These reduce the risk of eye problems such as cataracts and age-related macular degeneration. Spirulina can also improve oral health and reduce periodontal disease.


When it comes to training and fitness benefits, spirulina can help improve strength, endurance, and performance. In one study, men who took 6 grams of spirulina supplements daily for four weeks were able to enjoy longer periods of exercise without feeling fatigued compared to men who did not.

Supports Anaemia

Anaemia, a lack of healthy red blood cells, can lead to extreme fatigue. Spirulina has been shown to prevent anaemia in certain cases. For example, a study focused on older adults with anaemia found that spirulina supplements increased the haemoglobin content of red blood cells, which was particularly beneficial for older women.

Diabetes Management

Spirulina has also been shown to be effective in the prevention and treatment of diabetes. A review study found that supplementing with spirulina significantly lowered fasting blood sugar levels in people.

Nutritional Profile

Spirulina contains many important nutrients such as:

Protein: It is an excellent source of plant-based protein as it contains all nine essential amino acids.

Vitamins: This super algae is an excellent source of vitamins A, E, and K as well as vitamin B12.

Minerals: Spirulina is rich in minerals such as iron, copper, magnesium, potassium, and zinc.

Essential Fatty Acids: Spirulina is an excellent source of essential fatty acids such as omega-6 and omega-3.
