The Health Benefits of a Spirulina Supplement

Spirulina Health Benefits

There is ample evidence that spirulina helps human health in many ways both physically and mentally. The dark green algae contain a high concentration of chlorophyll, excellent for detoxifying the body, and it’s packed with vitamins, minerals and protein. Freeze drying allows the nutrients to remain in the finished product. And not be removed by processing that happens to many other supplements. Although there are many studies regarding the nutritional value and healing or preventative aspects, mostly involved testing on animals.


Evidence from several cancer studies indicates that spirulina may have anti-cancer properties. Those who took spirulina on a daily basis had a reduction in precancerous lesions of the mouth. When they stopped taking spirulina, the lesions returned for most people in the study. One serving of spirulina contains more enzymes, vitamins, minerals and antioxidants than the five servings of vegetables and fruits as recommended by the USDA and The National Cancer Institute.


Spirulina is high in antioxidants containing Phycocyanin, which protects the body from free radicals that damage the cells. It also contains anti-inflammatory properties that reduce inflammations in the body. Chronic inflammation contributes to a host of diseases including cancer and arthritis.

Liver Disease

Studies reveal that the high concentration of antioxidants and the abilities to eliminate toxins through the digestive tract offers protection from liver diseases and liver failure in people with hepatitis. Please note that it contains iron, 300 to 400ppm, which may not be acceptable for some that already have a liver disease.

Cholesterol Levels

In studies, spirulina has shown to reduce the LDL (or bad) cholesterol and triglycerides in the body, while increasing the good cholesterol known as HDL. With better cholesterol levels you will reduce your chances of heart disease and strokes.

High Blood Pressurehypertension reduction

High blood pressure or hypertension contributes to many diseases includes strokes, chronic kidney disease, and heart attacks. 4.5 grams per day reduces blood pressure by relaxing and dilating blood vessels.


When the body can’t produce enough insulin due to high blood sugar levels diabetes develops. Studies show that spirulina helps to lower blood sugar due to its high levels of GLA or gamma linolenic acid. GLA also controls insulin levels. Positive results in lowering blood glucose and HbA1c levels were found in a study of 25 patients with type2 diabetes while taking 2g per day in India. However, it has not been approved by the USFDA for that purpose.

Immune Support

Polysaccharides, one of the many nutrients in spirulina is one of the most potent immune boosters known. The immune system is built up by producing antibodies that help to fight off a variety of infections and chronic diseases. In test tube studies, there is evidence that it may help with influenza, herpes, and HIV. Studies show that even small amounts build up the immune system. Spirulina accelerates the production of antibodies so that it better protects against invading microorganisms.

Allergy Symptoms

Many people suffer from the symptoms of allergies such as running nose, nasal congestion, watery eyes, sneezing, swelling and hives. Spirulina may offer protection from allergic reactions. Studies show that taken daily it can significantly reduce these symptoms in some people.

Spirulina is a potent detoxifier. For that reason, it is best to start with a small dose and work your way up. Once you see how your body responds, you can then gradually increase your intake.
