If given a choice, most health conscious people choose organic foods over non-organic ones if they are able to. Of course, price factors into this decision as well. Organic products are usually more expensive than non-organic ones, and they are usually better.
But, is Organic Chlorella really that much better than "ordinary" Chlorella? Well, it depends...
It really depends on where and how the Chlorella is grown and processed. Just calling a product organic does not mean it is good quality. Chlorella grown organically in natural waterways does not mean it's any good. Why? Because it can pick up all kinds of pollutants from the environment including heavy metals and harmful bacteria. Organic Chlorella produced in polluted countries where there are lax restrictions on food safety is much worse than non-organic produced in a clean environment with food safety certifications. Organic and clean are not the same thing. So don't just go by the word "Organic." There is so much more to ask about the source.
So what is most important here, is finding out from your supplier where their Chlorella is produced and how it is produced. If they won't tell you, or make up some "It's proprietary" excuse, run! They should be able to tell you where they source it from. If not, they may have something to hide. They should be able to provide you with a CURRENT COA (certificate of analysis) from the batch you will be buying, not some old copy from years ago. They should also be able to provide you with periodic tests done at outside labs on such items such as heavy metals, radiation, pesticides, etc. Reputable producers will test their products with 3rd party labs at least once every 3-5 years. As long as their SOP (Standard Operating Procedures) don’t change during that time, that should be sufficient, along with a current COA of the batch you are buying.
We used to offer both organic and non-organic at ChlorellaFella.com to give customers that choice. However, the Organic was much more expensive, and we did not sell a lot of it. Typically, the only difference between the two is that the organic uses plant-based organic nutrients while the non-organic uses food safe nutrients. Both provide the same nutrients necessary to allow the algae to begin producing their own full range of nutrients.
The organic certification process is very expensive, making the cost of the final product expensive as well. Our 100% natural line is a great value, and an exceptional product, even though it is not certified organic.
