About Astaxanthin

A member of the carotenoid family, Astaxanthin is one of the most powerful lipophilic antioxidants yet discovered. Astaxanthin's antioxidant capabilities have shown to be up to 6,000 times more potent than vitamin C, 800 times more potent than CoQ10, 500 times more powerful than vitamin E, and 75 times more potent than alpha lipoic acid. Unlike some carotenoids, Astaxanthin does not convert to Vitamin A (retinol) in the human body and does not pose the risk of toxicity that is associated with high consumption of Vitamin A. The high level of antioxidant activity found in Astaxanthin indicates an increased ability to help support the many age-onset conditions related to oxidative stress.

About Supercritical Extraction

Because H. pluvialis naturally produces Astaxanthin when exposed to UV light, the Astaxanthin in this product is extracted using a solvent-free, supercritical, carbon dioxide process. Supercritical extraction methods are preferred for Astaxanthin extraction because the highest achievable concentrations in the extract when using organic solvents (e.g. acetone) are actually lower than what would be achieved without the use of such solvents, at least in the case of Astaxanthin.

The reason for this is hypothesized to be because of the composition of the microalgae, which contains Astaxanthin and some lipids, both of which dissolve equally readily in organic solvents like acetone. Consequently, Astaxanthin cannot be selectively separated from the lipids and standardized to higher concentrations using a solvent-based method. Conversely, much higher Astaxanthin concentrations can be achieved with the supercritical carbon dioxide process because of the flexibility to manipulate their dissolving power. Because lipids and carotenoids respond differently to supercritical carbon dioxide and can be selectively separated, it is possible to achieve an extract that is selectively high in the carotenoid, rendering the use of solvents not just unnecessary and inefficient.
