Astaxanthin
Astaxanthin is a potent keto-carotenoid belonging to a larger class of phytochemicals called terpenes. It is the pigment that gives salmon, shrimp, and other seafood their characteristic pink-red hue, and it is primarily sourced from the microalga Haematococcus pluvialis. Unlike some other antioxidants, astaxanthin possesses a unique molecular structure that allows it to span the entire cell membrane, providing comprehensive protection against free radical damage. Its strong antioxidant capacity is significantly higher than many other well-known antioxidants, including vitamin E and beta-carotene. This allows astaxanthin to effectively neutralize various types of free radicals and singlet oxygen without becoming pro-oxidant itself. Beyond its antioxidant roles, it also exhibits potent anti-inflammatory effects by modulating various signaling pathways involved in the inflammatory response. Supplementation with astaxanthin is commonly used to support eye health, improve skin elasticity and reduce UV damage, enhance athletic performance and recovery, and promote cardiovascular health. Its multifaceted actions make it a valuable ingredient for overall wellness, contributing to cellular protection and reduced oxidative stress.

add_circle_outline Positive Interactions
Vitamin E
Astaxanthin can regenerate oxidized Vitamin E, enhancing its antioxidant activity and allowing it to continue protecting cell membranes.
Vitamin C
As a strong antioxidant, Astaxanthin works synergistically with Vitamin C to provide broader protection against oxidative stress.
Lycopene
Both are powerful carotenoid antioxidants, and they may offer synergistic protective effects against oxidative damage when taken together.
Coenzyme Q-10
Both are lipid-soluble antioxidants that protect mitochondria and cell membranes, potentially enhancing cellular energy and antioxidant defense.
Omega-3
Astaxanthin can protect delicate Omega-3 fatty acids (like EPA and DHA) from oxidation, preserving their stability and beneficial properties.
EPA (Eicosapentaenoic Acid)
Astaxanthin can protect EPA from oxidation, thus maintaining the integrity and efficacy of this essential fatty acid.
DHA
Astaxanthin helps protect DHA from oxidation, preserving its structure and function, especially important for brain and eye health.
carotenoids
As a potent carotenoid itself, Astaxanthin can work synergistically with other carotenoids to enhance overall antioxidant protection.
