Astaxanthin Oil is a concentrated lipophilic preparation of astaxanthin, a naturally occurring carotenoid pigment belonging to the xanthophyll family.
It is widely recognized as one of the most potent lipid-soluble antioxidants, with a demonstrated capacity to scavenge reactive oxygen species (ROS) and singlet oxygen at significantly higher efficiency than other carotenoids such as β-carotene and lycopene.
Astaxanthin is produced naturally by the microalgae Haematococcus pluvialis, which accumulates high concentrations as a protective response to environmental stress.
It is also synthesized via chemical processes for certain industrial applications.
The oil form provides enhanced solubility and bioavailability, making it suitable for softgel encapsulation and lipid-based formulations.

Superior antioxidant activity: Exhibits singlet oxygen quenching capacity 10–100 times greater than other carotenoids.
Membrane protection: Traverses the phospholipid bilayer, offering antioxidant defense to both inner and outer membrane layers.
Anti‑inflammatory effects: Modulates NF‑κB and other pro‑inflammatory signaling pathways.
Photoprotection: Shields cells from UV‑induced damage and oxidative stress.
Lipophilic nature: Oil form facilitates absorption and integration into lipid‑based delivery systems.
Natural (extract from Haematococcus pluvialis): Contains a complex of astaxanthin esters (mono‑ and di‑esters) with natural fatty acids, typically standardized to 5% – 10% total astaxanthin content. Recognized as the preferred form for dietary supplements.
