What is Spirulina?

According the to the University of Maryland, spirulina is an algae that is blue-green in color. It is said that this algae is very rich in vitamins, minerals, carotenoids and protein. It also contains antioxidants that help to protect our cells from damage; and it grows in warm climates in alkaline waters.

It is advised that you do not obtain your spirulina from just any source as algae can be very toxic and contain microcystins. They can absorb metals found in the water in which they grow and this can lead to serious side effects.

Here is what was discovered about this algea

Several studies were done on this blue-green stuff and the results were great! More studies are still being done to determine if these are effective on people. Some of the studies that were conducted were done in test tubes so no conclusive human tests were done as yet. However the results are quite promising.

  • Immune System Booster: Test done in the lab and on some animals showed that there was an increased production of antibodies and proteins that fight off infections. A study conducted on chlorella (another algea) did not have the same effect.
  • Anti-Histamine: The tests that were done on animals and in tubes showed that spirulina inhibits the release of histamines. Studies are still being conducted to ensure that they will be effective on humans.
  • Boost Production of good bacteria: Antibiotics not only destroy bad bacteria but also the good ones. One study showed that spirulina increases the production of probiotics. Probiotics are good bacteria.
  • Protein Rich: Spirulina contains 62% amino acids.
  • May be able to treat Herpes, HIV and the Flu: Studies are still being done to prove whether or not this will be effective on humans.
  • May protect against liver damage and diseases: More research is being conducted to discover the extent of the treatment of these viruses.
  • Mouth cancer relief: A conclusive placebo study was done in people who chew tobacco. This study showed that the lesions caused from chewing tobacco had been affected by taking spirulina as opposed to the group who did not.

      Hi Teaches, I haven't stopped by your hubs in a while but I promise I will soon. Just dealing with some stuff. Haven't been able to read much these days.

      I only just found out about spirulina myself, it seems that even though it's good it can have some serious effects as well.

      Good information to know on spirulina . I have heard of it before and how well it benefits the body, but also knew of the precautions that come with it. Well done and researched. Voted up.

      Hey Alexander. This algae seems to be a super supplement and I am glad I discovered it too. I am thinking of trying it myself. Thanks for reading and commenting. Have a great weekend.

      Oh yes, this is good stuff. I drink Odwalla Superfood which contains 1000 mg of spirulina. My brother takes it in powder form. There is a noticeable change in how I feel (better), and especially my mental alertness improves when I take it, I can actually think a lot better. Same for my brother. Who would have thought some algae could do that? In any case, I didn't set out to obtain spirulina, I just stumbled on it - discovering the effects as I drank the Odwalla and later doing research to find out why. This stuff works!

      Hi James, good to see you. I haven't been around much either. I have been having some health issues and now a family crisis, but I am hanging in there. How have you been?

      I also found out about chlorella in the process. I don't know much about it but from what I gather spirulina is very good for a lot of stuff.

      Hey, Carolee, sorry I haven't been around much, barely communicating with anybody, unfortunately. I have been taking Chlorella because of a thyroid condition. There's two thyroid conditions and I never remember which I have. As you, I stumbled across it. As you said, this is also an algae, and is grown in the "pristine" waters of the Ishigaki-shi Islands of southern Japan. When I saw spirulina in your title I thought it might be what I am taking, which needs no prescription. But, yes, they are different.

      Good to see you, kid!

      I haven't discovered where it is harvested as yet, Mjboomer, but I know I have some more research to do. Thanks for reading and commenting.

      Blue-green algie is said to be very good for you. At one time it was harvested from Klamath Lake in Oregon where it is found in abundance.
