Astaxanthin is a powerful carotenoid pigment found naturally in certain marine organisms, particularly microalgae, salmon, and krill. It is known for its exceptional antioxidant properties — considered to be significantly stronger than vitamin C, vitamin E, and other carotenoids like beta-carotene.
In sports nutrition, astaxanthin is valued for its ability to reduce oxidative stress and inflammation induced by intense physical activity. By neutralizing free radicals, it may support faster recovery, reduce muscle damage, and improve endurance. Some studies also suggest benefits for skin protection and visual function, which can be relevant for outdoor athletes.
Its lipid-soluble nature allows it to incorporate into cell membranes, providing structural protection and improving mitochondrial efficiency — which is particularly interesting for endurance athletes and those exposed to high oxidative loads.
Synonyms:
3,3′-Dihydroxy-β,β-carotene-4,4′-dione, Natural astaxanthin
Benefits:
- Potent antioxidant protection against exercise-induced oxidative stress
- May reduce muscle damage and inflammation post-workout
- Supports endurance by improving mitochondrial function
- Protects skin and eyes from UV and oxidative damage
- May aid immune modulation under physical stress
Sources:
Naturally derived from microalgae (Haematococcus pluvialis), also found in krill, salmon, trout, and shrimp; available in capsule or softgel form.
Observations:
Effective doses typically range from 4–12 mg/day. Should be taken with fats for better absorption. Well-tolerated, with no known serious side effects at standard dosages. High doses may cause harmless skin pigmentation (slight orange tint).
