Health Effects of Astaxanthin
The health effects of astaxanthin are numerous and well-documented in various studies 1, 2, 3, 4, 5. Some of the key health benefits associated with astaxanthin include:
- Antioxidant, anti-inflammatory, and anti-apoptotic properties 1, 2, 3, 4, 5
- Neuroprotective effects, including potential benefits for Alzheimer's disease, Parkinson's disease, and other neurological disorders 1, 2, 4
- Cardiovascular health benefits, such as lowering triglycerides and raising HDL-cholesterol 3
- Anti-aging potential, including protection against oxidative stress and inflammation 3
- Benefits for skin and eye health, including protection against skin photo-aging and potential treatment of eye diseases like glaucoma, cataracts, and uveitis 4, 5
- Potential benefits for exercise performance, immune response, and intestinal flora regulation 2, 3, 5
Specific Health Benefits
Some specific health benefits associated with astaxanthin include:
- Lowering oxidative stress in overweight and obese subjects and in smokers 3
- Blocking oxidative DNA damage and lowering C-reactive protein (CRP) and other inflammation biomarkers 3
- Boosting immunity in the tuberculin skin test 3
- Improving cognition and boosting proliferation and differentiation of cultured nerve stem cells 3
- Improving visual acuity and eye accommodation 3
- Improving reproductive performance in men and reflux symptoms in H. pylori patients 3
Mechanisms of Action
The mechanisms of action underlying the health effects of astaxanthin are not fully understood, but are thought to involve its antioxidant and anti-inflammatory properties, as well as its ability to regulate redox balance and multiple biological mechanisms 2, 4. Further research is needed to fully understand the mechanisms of action and to establish accurate recommendations for dietary intake of astaxanthin 2.
