What is Astaxanthin?
The dietary supplement industry is full of fads. But every so often, an ingredient comes along that has staying power. TruAzta natural astaxanthin is one of them. Astaxanthin, the red pigment giving salmon, shrimp and even the feathers of flamingos their beautiful pink-red color, is a carotenoid with powerful carotenoid- and antioxidant-related activity. 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.
- Astaxanthin is a xanthophyll carotenoid.
- As a carotenoid, it converts light filtering benefits.
- Astaxanthin has the ability to induce detoxification enzymes and facilitates cell-to-cell interactions.
- Astaxanthin can cross both the blood-brain and blood-retinal barrier, giving it the ability to position itself where it can provide optimal benefits.
- Astaxanthin, unlike other carotenoids such as lutein and zeaxanthin, never becomes a pro-oxidant.
- Astaxanthin's polar-non-polar-polar molecular configuration allows insertion into the cell membrane, where it can intercept dangerous reactive oxygen species within the cell's hydrophobic interior and its hydrophilic boundaries.
Singlet-oxygen is a high energy form of oxygen and is extremely reactive toward organic compounds. Singlet-oxygen is one source of oxidative stress. In a paper published by Nishida in 2007, it was demonstrated that astaxanthin is orders of magnitude more powerful at quenching these damaging molecules than other popular antioxidants.
Yet not all astaxanthin is created equally. Synthetic astaxanthin contains a mixture of astaxanthin isomers, only 25% of which is the form providing the highest levels of bioactivity. TruAzta is an optically pure composition of the form demonstrated by peer reviewed, scientific research to be the most biologically active form of astaxanthin.
The TruAzta™ Difference
TruAzta is high quality natural astaxanthin extracted from the microalgae Haematococcus pluvialis. These microalgae are grown in controlled, natural conditions and the astaxanthin is extracted using supercritical CO2 extraction, a solvent-free extraction process eliminating the risk of harmful chemical residues. The final product is a dark red, viscous oleoresin for use in a wide variety of products such as nutraceutical supplements, food products and cosmetics.
