Viridian’s Naturally Sourced Astaxanthin

When it comes to sourcing ingredients, sustainability and ensuring minimal environmental impact are paramount to Viridian. Read on to learn about Viridian’s astaxanthin and why it’s one of the richest natural sources available.

Astaxanthin is a red pigment which belongs to the xanthophyll carotenoid group naturally found in sources such as salmon, algae, and crustaceans. Viridian’s Astaxanthin is sourced from freshwater microalgae, known as Haematococcus pluvialis.

The microalgae are cultivated using natural waters from the Himalayas and uses large photobioreactor glass pipes which are situated outside, allowing natural sunlight in, and providing an ideal climate for the algae to grow. This natural process allows for minimal environmental impact because the algae can grow in natural waters with no heat applied from any machinery.


Viridian Astaxanthin - provenance


Viridian’s Astaxanthin includes a base or marigold flower, which contains active carotenoids Meso-zeaxanthin, Lutein and Zeaxanthin. Together, these three carotenoids accumulate the central retina and are the main components of macular pigment and play an important role in optimal visual performance1.

The biosynthesis of synthetic astaxanthin involves many transformations from isopentenyl pyrophosphate into a non-esterified astaxanthin which is all free form. Methods of production include metabolic engineering of the yeast, Xanthophyllomyces dendrorhous, formerly known as Phaffia rhodozyma.

The main difference between natural algae astaxanthin and synthetic astaxanthin is natural astaxanthin is more than 95% esterfied, which means they still have the natural fatty acids attached to either one or both ends of the molecules.

Viridian’s astaxanthin is produced from the natural algae, Haematococcus pluvialis. It is extracted at the source and dried. The result of this is a natural, high quality Astaxanthin.

Viridian’s Astaxanthin contains 100% active ingredients, with no additives whatsoever. There are no added sugars, no colourings or artificial flavourings, making the product as clean and pure as it can be. Viridian Nutrition is against the use of animal testing and do not test any products or ingredients on animals.


Viridian’s Astaxanthin is palm oil free and is also vegan. The formulation is based upon scientific research for safe use in human consumption.
