Astaxanthin — 4 mg

💊 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.

⚡ Interactions & combinations
Generally extremely well tolerated — one of the safest supplements in clinical use. Mild carotenodermia (orange tinting of skin) at very high doses (cosmetically harmless). May lower blood pressure slightly.
🛡 Safety notes
Excellent safety profile. No established upper limit based on adverse effects. High doses (above 40 mg/day) cause harmless skin tinting.
🌿 Vegan note
Haematococcus pluvialis microalgae-derived astaxanthin is plant-based — this is the primary commercial source and is specifically suitable for vegans.
Moderate evidence
Good evidence, though not unanimous across all research.
