ANTI HANGOVER AID
Here are a few findings worth taking into account if you choose to purchase else where:
Chlorella from China was the most contaminated on the market.
• Aluminum: 29 ppm
• Arsenic: 0.89 ppm
• Cadmium: 0.17 ppm
• Lead: 0.27 ppm
The number one concern here is the aluminum concentration. Given that aluminum intake is something most people seek to avoid, it seemed important to document the aluminum levels in various sources of chlorella.
Even "Organic" chlorella from China was far more contaminated than non-organic chlorella from other countries
Certified organic doesn't necessarily mean cleaner chlorella. In fact, the cleanest chlorella that was found wasn't certified organic at all.
You might wonder: How can this be? Doesn't organic mean clean? No! Organic certification is the certification of a growing process, not an end result. You can follow organic practices, but if you're growing chlorella right next to a chemical plant, for example, you're going to get some cross-contamination in the soil, the air, or the water that's used to grow chlorella. Your chlorella can still be 100% certified organic even though it's far more contaminated with metals than non-organic chlorella.
This is an important distinction because most people equate organic with "clean." But that's a huge mistake, because with chlorella, the country of origin seems to be far more important than whether it's organic or conventional.
Organic certification does not require testing for heavy metals, by the way. A product can be heavily contaminated with aluminum, lead and even mercury and still be certified "organic" by the USDA.
The cleanest chlorella from Taiwan is hardly sold by anyone because it's too expensive.
In terms of chlorella grown outdoors in large cultivation pools, Taiwan was by far the cleanest source.
There are three chlorella producers in Taiwan, each with varying degrees of quality and purity in their final product. The cleanest producer of chlorella in Taiwan is a certified organic producer whose final product is so expensive that, to my knowledge, almost nobody sells it in North America.
