However, astaxanthin is virtually insoluble in gastric and intestinal fluids, giving it poor bioavailability. Even in solubilized formulas, it quickly precipitates out once saturation is reached, making it hard for the body to absorb and utilize. MicroActive Astaxanthin was developed to address this issue through a micronized, sustained-release technology that allows for better absorption and retention.
A pilot human study comparing MicroActive Astaxanthin to another astaxanthin preparation (10% astaxanthin in oil) showed it has:
MicroActive technology is a delivery system. MicroActive Astaxanthin micronizes astaxanthin into smaller particles (10 microns), allowing for greater absorption in the small intestines. In addition, the special mix of polymers in MicroActive Astaxanthin slows the rate at which the astaxanthin is released, so more astaxanthin is absorbed over time.
Astaxanthin is found in many foods — such as yeast, salmon, trout, krill, shrimp, lobster, and crayfish — and has been safely consumed as part of the food chain for thousands of years. Human clinical studies have found no adverse effects from the use of astaxanthin.
