Spirulina - arthrospera platensis, is very good for you. I suggest looking up this web site.

This is one of the best companies producing spirulina, and astaxanthin.  Astaxanthin is much better than spirulina . Thousands times more potent than vitamin c as antioxident. I buy and sell stocks in companies that produce high quality products. This is one of them. I think you will like their web site with the info. There are a great many benefits . My vision has really got better. Not too many people know about this supplement , yet.  Spirulina, astaxanthin  is not a diet pill.

Before you take ANY diet pills you should read ALL the instructions and side effects printed on the back of the package or BETTER YET, consult your doctor. Even more so if your taking any other medications that may produce harmful side effects.
