10 Cognitive Benefits of Astaxanthin and Lutein

other foods, have proven brain-boosting and cognitive enhancing abilities. Re- search suggests lutein and astaxanthin may decrease the risk of various cognitive disorders and improve visual function in both young and aging adults A recent systematic review found that


carotenoids like astaxanthin and lutein may improve various cognitive and visual functions when taken as oral supplements for 12 months. While it's not surprising that the intake

of such powerful antioxidants like carot- enoids would have such beneficial effects, researchers have been impressed with the variety of cognitive benefits these particu- lar carotenoids produce. To summarize this research, we've compiled a list of the top five cognitive benefits associated with the consumption of both astaxanthin and lu- tein.

Top Five Cognitive Benefits of Astaxanthin

1. Improves Age-Related Macular Degen- eration

Loss of eyesight due to macular de-

generation is a serious concern for many older adults. In one study, participants who took oral supplements containing both lutein and astaxanthin saw an improve- ment in the health of the central retina after just 12 months of supplementation.

2. Promotes Recovery From Mental Fa- tigue

Many healthy adults are severely af-

fected by mental fatigue. In a study involv- ing healthy participants each taking astax- anthin supplements for four weeks at a time, astaxanthin supplementation was shown to improve mental fatigue by in- creasing antioxidant function and reducing oxidative stress, one of the precursors to mental fatigue. Additionally, astaxanthin supplementation produces no adverse ef- fects.

3. Improves Cognitive Function in Aging Adults In a larger double-blind study of 96

healthy aged participants, researchers tested the effects of astaxanthin supple- mentation on cognitive function after just four weeks. The researchers found that due to the strong antioxidant properties of astaxanthin, which consumes free radicals as it scavenges through the body and brain, it produced strong cognitive benefits even after a short supplementation period. Researchers theorized that astaxanthin supplementation could be further used to prevent or diminish the effects of other age-related degenerative diseases such as Alzheimer's disease and other forms of dementia. These findings have been further vali-

dated with additional studies that found astaxanthin supplementation improved psychomotor speed and processing speed, improving the ability to comprehend and perform various complex tasks quickly and accurately in participants suffering from mild cognitive impairment (a precursor to dementia). Researchers now believe astaxanthin

could be used to maintain cognitive func- tion in adults already diagnosed with these diseases.

4. Radioprotective Potential As concern with radiation exposure

in modern society continues to rise, re- searchers are eager to find natural com- pounds that protect our cells. Due to astaxanthin's powerful anti-

oxidant and anti-inflammatory properties and its neuroprotective and radioprotec-
