From the Research
Astaxanthin is a naturally occurring reddish pigment that belongs to the carotenoid family, found primarily in marine organisms like salmon, krill, shrimp, and microalgae, and has been shown to have potent antioxidant and anti-inflammatory properties, with potential benefits for cardiovascular health, skin health, and eye health, as demonstrated in a 2021 review of human clinical trials 1.
Key Characteristics of Astaxanthin
- Astaxanthin is a ketocarotenoid with higher antioxidant activity than other carotenoids, making it a potential therapeutic agent for various diseases, including cardiovascular disease, cancer, and neurodegenerative disorders 2.
- It has been shown to have anti-inflammatory effects, which may contribute to its potential health benefits, including reducing oxidative stress and inflammation in the body 3.
- Astaxanthin is fat-soluble, so taking it with meals containing healthy fats can improve its absorption in the body.
Potential Health Benefits of Astaxanthin
- Cardiovascular health: Astaxanthin may help reduce the risk of cardiovascular disease by reducing oxidative stress and inflammation, and improving blood lipid profiles, as suggested by a 2012 study on astaxanthin in cardiovascular health and disease 4.
- Skin health: Astaxanthin may help protect the skin from damage caused by UV radiation, and improve skin elasticity and hydration, as reported in a 2006 review of astaxanthin's potential health benefits 5.
- Eye health: Astaxanthin may help reduce the risk of age-related macular degeneration, and improve visual acuity, as suggested by a 2021 review of astaxanthin's potential health benefits 1.
Dosage and Safety
- The typical dosage of astaxanthin is 4-12 mg per day, although the optimal dosage for specific health benefits is not well established.
- Astaxanthin is generally considered safe, with no significant adverse events reported in clinical trials, as noted in a 2009 study on the safety and efficacy of astaxanthin 3.
