Ingredients found in salmon and salmon roe are extracted from Haematococcus pluvialis.

Astaxanthin is a red-orange pigment found in salmon and krill and is classified in the xanthophyll group of carotenoids. The name astaxanthin comes from the fact that this component was first detected in American lobster (Astacus gammarus L.).
Currently, the main raw material for astaxanthin extraction is derived from Haematococcus pluvialis. Haematococcus pluvialis is a type of green algae that is normally green in color, but when cultivated under harsh conditions, it produces astaxanthin to protect itself, and its appearance changes to red. Astaxanthin is extracted at this time.
You may not often hear the name astaxanthin, but it is an ingredient found in familiar household foods such as salmon and sea bream. Astaxanthin, produced by Haematococcus pluvialis to survive, has a positive effect on our bodies.
