💊 What it does
Astaxanthin is a carotenoid pigment responsible for the pink colour of salmon, flamingos, and shrimp. It is produced by the microalgae Haematococcus pluvialis and is considered one of the most powerful natural antioxidants known — 6,000 times more potent than vitamin C and 800 times more potent than CoQ10 as a free radical scavenger by some measures. Unlike beta-carotene, it does not act as a pro-oxidant at high doses. Evidence supports benefits for skin health, eye health, exercise performance and recovery, cardiovascular protection, and anti-inflammatory effects.
👤 Who needs it
People interested in skin health and photoprotection (astaxanthin from within reduces UV-induced skin damage). Those doing intense exercise who want antioxidant recovery support. People with eye strain or macular degeneration concerns. Anyone wanting a broad-spectrum antioxidant with an excellent safety profile.
🥦 Food sources first
Astaxanthin is found in microalgae, salmon, trout, krill, shrimp, and lobster — all either animal sources or microalgae. Plant-based eaters have no food-based astaxanthin sources other than the algae itself. This is one supplement where plant-based eaters genuinely have lower intake than omnivores.
🗓 When to supplement
For skin health and UV protection — evidence is consistent. For exercise recovery. For eye health support. As a premium broad-spectrum antioxidant.
🏷 Best form to look for
Haematococcus pluvialis microalgae-derived astaxanthin is the gold standard for purity and potency. AstaReal is a well-studied branded form. Softgel in oil is essential — astaxanthin is fat-soluble and bioavailability from dry powder capsules is poor.
⏰ When to take it
With a fatty meal — fat-soluble. Morning or lunchtime is conventional.
