What are the Spirulina side effects?

Spirulina is a kind of blue-green algae that comes with the scientific name of Arthrospira platensis. Spirulina has an odor and taste that is very much comparable to seaweed.

Spirulina is usually found in freshwaters like lakes, ponds, and rivers. This grows under good sunlight, moderate temperature level, and pesticide-free environment, but it can also survive with extreme conditions since it also has the ability to easily adapt to its environment.

There are over 25,000 species of algae that can be found all over the world. They mostly live in soils, water, rocks, or plants. But among all of these, Spirulina is considered to be highly nutritional that is why it is processed and used as a potent dietary supplement.

  •   Anti-cancer

Research studies prove that eating various fruits and vegetables that is rich in beta carotene may help the body increase its anti-cancer protection. Synthetic or artificially prepared beta carotene does not show to be beneficial as anti-cancer but natural beta carotene from algae such as in Spirulina has been proven to be highly effective because it contain more antioxidants and anti-cancer power.
