Are All Astaxanthin Ingredients Made Equal?
The answer is unequivocally NO.
Astaxanthin is one of nature’s most powerful antioxidants, orders of magnitude greater antioxidant capacity than other common antioxidants such as vitamin C, vitamin E, and beta-carotene. Yet not all astaxanthin is created equally. There are three key attributes that separate natural astaxanthin, and specifically TruAzta astaxanthin, from synthetic astaxanthin and other natural astaxanthin products:
- Isomerization:The astaxanthin molecule exists as stereoisomers and geometric isomers. Synthetic astaxanthin contains only 25% of the 3S,3’S form which provides the highest level of bioactivity. TruAsta’s composition is over 99% 3S,3’S-isomer, the isomer demonstrated by peer-reviewed, scientific research to be the most bioavailable form of astaxanthin.
- Esterification: Astaxanthin exists in both free and esterified forms. Algae-sourced TruAzta is 95% esterified compared with non-esterified or free synthetic astaxanthin. The mono-or diesterified molecule provides increased stability and bioavailability over the synthetic molecule.
- A Complete Oil Sets TruAzta Apart: Pharmaceutical drugs are delivered with excipients, carriers, and other components that enhance the benefits of the active ingredient. With astaxanthin, nature created this complex delivery carrier system for you. TruAzta astaxanthin oleoresin is concentrated astaxanthin surrounded by the natural algae oil containing additional carotenoids, amino acids and fatty acids that are naturally produced alongside the powerful astaxanthin molecule.
Published research literature supports increased bioavailability and greater antioxidant potential from natural versus synthetic astaxanthin. Heliae has not evaluated the validity of these claims.
