Health Benefits of Spirulina:

1) Anti-cancer Properties: Studies show that spirulina may prevent colon cancer and other forms of cancer.

It may also protect against cardiovascular diseases such as heart attacks, strokes and high blood pressure. Other studies suggest that it could lower cholesterol levels and increase good HDL cholesterol levels in the body.

2) Antioxidant Properties: Spirulina may provide protection against free radicals and other harmful substances.

These compounds are produced when cells are damaged due to stress or aging. Free radicals cause damage to healthy tissue and organs causing disease. They can lead to cancer, heart disease, stroke, dementia and many other diseases.

5) Good Source of Protein and Vitamin: It’s a good source of plant-based protein for vegetarians and vegans.

It also contains B complex vitamins as well as vitamin E and can be used to enhance the nutritional value of other foods.

6) Purifies Water: Due to its high levels of phycocyanin, spirulina can be used as a natural method of treating water.

It helps to kill bacteria and other organisms that can make water unhealthy.

7) Reduces Cholesterol: Some studies show that spirulina has a positive effect on reducing cholesterol levels in the body.

It may help reduce LDL (bad) cholesterol and triglyceride levels in the body while increasing HDL (good) cholesterol.

8) Lowers High Blood Pressure: High blood pressure or hypertension is considered to be one of the silent killers of modern society.

It has no symptoms and often there are no outward signs that something is wrong. High blood pressure or hypertension can lead to many other diseases such as heart attacks, strokes, kidney failure and eye problems. Larger studies are still needed to confirm these results but spirulina may play a role in preventing and reducing hypertension.
