Spirulina is a natural whole aliment and there are no reported side effects related to consuming it on a daily basis, or as a supplement from time to time.

  It has been shown that taking 50 grams or less per day should be reasoned safe to add to our diet, although is very important to advance with a small amount at first, to observe how our bodies answer back to it .

  Another extremely important fact is that spirulina and chlorella products are being grown in clean waters that are not infested with heavy metals and toxins.

  The company that sells this super food must attest that their product is free of heavy metals (like mercury), pesticides and other toxins.

 Another good question is to find out in what country it was grown and in what waters therefore we can get a larger picture about the product that you are consuming.

 

Not being attentive at the quality of the product can bring upon the consumer some side-effects like:

 

-Stomach ache and gastrointestinal symptoms;

 

-Slight dizziness and nausea;

 

- Slight fever; 

 

  But we have to keep in mind that the health benefits of spirulina outnumber any side effect that we might find when consuming it. These side effects can be lowered to a very minimum if we are careful when choosing the source and the quality of the product.

  Furthermore these side effects we can find them related to the toxin removal that spirulina and chlorella will bring as an effect of absorbing them.

  The University of Maryland Medical Center website warns that if you are pregnant or breastfeeding or you have an autoimmune disease like lupus, or you have arthritis you shouldn't take any form of spirulina, and that this supplement may interact with some medication.

 

  Pregnant and breastfeeding women should consult with their physician first, but the safety of supplementing spirulina or chlorella to their diet is not attested.

  Some the immune system suppression medication or drugs related to autoimmune disease can interact with these blue green algae and so patients that are under a prescription should also consult their physician.

  If you are pregnant or breast feeding you should consult with your doctor before taking spirulina.

  To prevent constipation, when taking this super food, one should always increase the water intake so the absorption will be optimal.

  Therefore blue-green algae is a complete and a natural food source , even if we take too much of it, there should not be a problem , but still we should not waist this product but take it as recommended on the product prospect
