Description
"Astaxanthin" is a naturally occurring carotenoid found in microalgae, particularly Haematococcus pluvialis. It contributes to the red-orange pigmentation in marine organisms such as salmon and shrimp. This compound integrates into cellular membranes, engaging with lipid structures, oxidative processes, and molecular stability. It also interacts with biochemical pathways that influence mitochondrial dynamics and redox balance. As a structurally unique carotenoid, astaxanthin remains a key element in marine-based biological systems and naturally occurring pigment compositions.

Warnings
Astaxanthin may interact with high levels of calcium, magnesium, or iron, potentially affecting its absorption or efficacy. It's advised to avoid excessive intake of these minerals when supplementing with astaxanthin.
Food Sources
Astaxanthin is found in natural sources such as algae, yeast, salmon, trout, krill, shrimp, crayfish, crab, and lobster.
Time Frame
Astaxanthin is best absorbed when taken with meals containing fat, as it is a fat-soluble compound.
Depleted By
Astaxanthin levels may be reduced by a poor diet, particularly one lacking in nutrient-dense foods.
