Perhaps downsize the amount you are taking until you find an amount your body will accept. Every”body” is different and reacts differently. Just a thought.

chlorella has tons of vitamin b12 and other b vitamins there for that could be whats making you feel nauseous. like marit77 said, take a smaller amount next time

Hi Nannette! What is the source of your chlorella? if you are obtaining it from this site then I don’t know of the source, but I know some chlorellas, even organic, are spawned in areas with extremely high toxicity and heavy metals nearly everywhere. I would always check with manufacturers and get a heavy metals report, generally they don’t contain enough info to even tell anything -_- But if it is from this site, then perhaps it is just a really high concentration and you need to start small as others have noted. Please keep us posted, I would love to hear your experience with chlorella. For me, I have taken Sun chlorella (http://www.amazon.com/Sun-Chlorella-Nutritional-Tablets-Count/dp/B00186V14Y/ref=sr_1_16?ie=UTF8&qid=1424386079&sr=8-16&keywords=chlorella) but good god is it expensive so I stopped.

cuddleycake- I got my chlorella from earthshiftproducts. I wonder if my bad reaction to it is because it it detoxing me. I have on mercury filling.
