Phyto•Blast is a nutritious complex of several naturally occuring marine phytoplankton in a wide range of sizes from 1 to 20 uM. Phyto•Blast is real phytoplankton, aquacultured in saltwater under pristine conditions, not simply a mixture of freshwater algae or ground up vegetables. It provides for growth and increased coloration, by providing proteins, naturally occuring lipids, including important omega fatty acids EPA and DHA, and a wide range of vitamins. It also contains chlorophyll, carotenoids, astaxanthin, zeaxanthin and canthaxanthin for coloration. Phyto•Blast does not require refrigeration, but refrigeration will prolong shelf life.
