About Astaxanthin NZ

Astaxanthin is a reddish-pink pigment created by microalgae that give many sea creatures such as krill, salmon and crayfish their red colour. When certain algae are stressed by a change in their environments such as a change in temperature or a change in UV light, they release Astaxanthin to defend themselves. When released, the Astaxanthin surrounds the algae and protects it, giving it the ability to survive through tough conditions. It is these protective properties that have sparked so many new studies with new human health applications constantly being discovered.

Biosphere provides a cost effective and easy way to get ideal amounts of Astaxanthin each day.

Where is Astaxanthin
found in the nature?

Astaxathin is found in a wide range of natural organisms. It is predominantly found in marine life and traced back to a specific green algae called Haematococcus pluvialis. When eaten or stressed, this algae turns red, producing astaxanthin to try and protect itself. This algae is consumed by different types of marine life such as salmon, krill, lobsters and flamingos making them pink but also another source of Astaxanthin.

Astaxanthin however is not limited to only marine life, as there is a type of yeast called Phaffia that also produces Astaxanthin but at lower levels to the algae.

As haematoccus pluvialis is at the bottom of this marine life food chain and the source of the Astaxanthin, it has by far the highest concentrations, making it great for sourcing high doses of Astaxanthin.
