Supercritical extraction means no toxic solvents!
Speaking of high quality ingredients, I think it's important to know how nutrients are extracted from their natural sources. Sadly, some companies use toxic, explosive chemicals to extract their nutrients. A famous provider of DHA oils, for example, uses highly toxic hexane to extract the oils. That's just plain awful.
Supercritical CO2 extraction, on the other hand, is safe and far more "natural." It uses compressed CO2 to pull out key nutrients, after which the CO2 evaporates harmlessly into the ambient air (from which the CO2 was gathered in the first place). Thus, it introduces no new chemicals into the environment, and it leaves nothing in the resulting product that might be harmful to you. This process -- called "supercritical CO2 extraction" -- is the best extraction process in the business, and it's used on premium-quality supplements like neem oil. It also happens to be the process used by Cyanotech to extract their astaxanthin from the Haematococcus algae.
That means this astaxanthin contains no toxic solvent chemicals whatsoever! That's one of the many reasons why we gave it our Editor's Choice award: Because it's an honest product, with zero chemical contaminants (or as close to zero as you can get on the planet today), that offers astounding health benefits. Cyanotech's astaxanthin deserves every bit of publicity we can bring it. I truly consider it to be one of the most important nutrients ever discovered for human health.
