Astaxanthin is a naturally occurring carotenoid with all kinds of nutraceutical purposes within the combat towards ailments. Knowledge now reveal astaxanthin has important promise as a geroprotector, serving to to gradual mind growing older.1 Astaxanthin is chargeable for the pink or crimson colour of salmon, trout, lobster and different seafood.2

In keeping with Science Direct, “when in comparison with different antioxidants equivalent to lycopene, vitamin E and vitamin A,” astaxanthin comes out on prime and is also known as the “king of antioxidants.”3 It’s derived from Haematococcus microalgae, which produce astaxanthin as a protecting mechanism to defend from harsh ultraviolet (UV) light.4

In your physique, it really works as an antioxidant to assist defend towards reactive oxygen species and oxidation. These processes play a job in growing older, coronary heart illness, Alzheimer’s illness and Parkinson’s illness.5 Knowledge present astaxanthin can defend your pores and skin towards free radical injury from UV gentle from the within out.6

In 2015, NASA offered on the 66th Worldwide Astronautical Convention and shared data exhibiting {that a} provide of astaxanthin from pure sources might probably forestall the detrimental results of radiation publicity, injury to the eyes and different well being results recognized to happen to astronauts in house.7,8

Highly effective Antioxidant Slows Mind Growing older

Researchers writing within the journal Marine Medication acknowledge the problem of sustaining mind operate and well-being as human life expectancy lengthens.9 Current research have evaluated the neuroprotective impact astaxanthin has on preserving mind growing older in experimental fashions.

Of their assessment of the literature, the scientists recognized a number of pathways astaxanthin could absorb slowing mind growing older. They evaluated the outcomes of medical trials the place the endpoint measure was illness and incapacity.

They discovered a number of research the place astaxanthin modulated organic mechanisms, together with transcription elements and genes straight associated to longevity. One of many primary related elements modulated by astaxanthin is the forkhead field 03 gene (FOXO3). That is one in all solely two genes with a major impression on human longevity.

Moreover, of their search of the literature, they discovered astaxanthin will increase brain-derived neurotrophic factor (BDNF) ranges within the mind and may attenuate oxidative injury to DNA, lipids and protein.10

They concluded that it was doable astaxanthin can promote longevity and gradual the speed of growing older. The neuroprotective properties seem like attributed to astaxanthin’s means to scale back oxidative stress and irritation in addition to enhance mitochondrial operate and the dysregulation of gene expression that happens with growing older.

Mind Growing older Impacts Psychological Operate

The info exhibiting astaxanthin could assist gradual mind growing older is critical because the neurological growing older course of is straight tied to cognitive operate. Cognitive adjustments that may happen, however usually are not essentially regular, embody discovering it tough to recollect phrases, recall names, having issue with multitasking or having extra issue paying consideration.11

In keeping with the Nationwide Institute on Growing older, a few of the frequent adjustments that may happen within the mind embody lack of mind quantity, decreased blood move, irritation and lowered effectiveness in communication between neurons. Every of those adjustments have an effect on cognitive operate.

After age 40, knowledge present the amount of the mind can decline at a charge of 5% for each decade. This charge can enhance as an individual reaches 70 and older.12 The first issue for this shrinking is unclear however scientists counsel there’s a decline in quantity relatively than within the variety of neurons that will have a relationship to gender.

Though specialists discover there are frequent adjustments in considering skills that decline with age, in addition they discover studying, vocabulary and verbal reasoning could enhance as an individual ages.13 With irregular growing older adjustments, there could also be extreme cognitive impairment that impacts reminiscence, downside fixing and habits, related to dementia.

In keeping with the Alzheimer’s Affiliation, there are greater than 5 million within the U.S. who’ve Alzheimer’s and that quantity is predicted to almost triple to 14 million by 2050.14 The price of these dementias is projected to be $305 billion in 2020 and estimated to rise as excessive as $1.1 trillion by 2050.

What Makes Astaxanthin Distinctive?

Though astaxanthin is said to beta-carotene, lutein and canthaxanthin, the molecular construction is exclusive and stronger than different carotenoids. One of many key variations is that astaxanthin has a surplus of electrons to donate because it neutralizes free radicals.15 

Antioxidants work by donating one in all their electrons to a free radical with a view to stabilize it. Nonetheless, in donating an electron the antioxidant could then develop into unstable. Astaxanthin has a surplus of electrons and so can donate many occasions with out changing into unstable itself.16

One of many extra distinctive options of astaxanthin is that it is capable of defend each water- and fat-soluble components of the cell. This function makes astaxanthin highly effective. In a single research analyzing a number of antioxidants and their effectiveness, knowledge present astaxanthin had antioxidant energy larger than alpha-lipoic acid, green tea catechins, CoQ10 and vitamin C.17

Most antioxidant carotenoids are both water-soluble or fat-soluble, however astaxanthin can interface between water and fats, which makes it more practical. Astaxanthin can also cross the blood-brain barrier, the place it will probably exert a robust protecting impact in your neurological well being.18

Lastly, astaxanthin can not operate as a prooxidant,19 that are molecules that trigger relatively than fight oxidation.20 Different antioxidants will be prooxidants when there’s a ample focus, which is one motive you do not wish to take too many antioxidant dietary supplements. Nonetheless, astaxanthin is not going to operate as a prooxidant, even when current in massive quantities.

Astaxanthin Has Complete Physique Advantages

Proof exhibits astaxanthin advantages your complete physique. A number of research exhibit the helpful impact it has on pores and skin well being and the safety it affords towards UV solar injury, growing pores and skin elasticity and decreasing the looks of high quality wrinkles.21,22,23 In contrast to topical sunblock, astaxanthin doesn’t block UV rays so that you get the advantage of your pores and skin producing vitamin D from UVB gentle.

The impact is so potent it will probably defend towards whole physique irradiation24 and burn wound development.25 As efficient as it’s on the tissue you see, astaxanthin additionally has a major impression in your inner organs and tissues.

In a single double-blind, placebo-controlled research, individuals who took 12 milligrams (mg) of astaxanthin every day for eight weeks had a 20.7% lower in C-reactive protein, a marker for coronary heart illness.26 In one other research printed in Atherosclerosis, individuals had been randomly chosen to take a placebo or a every day dose of astaxanthin for 12 weeks at 6 mg, 12 mg or 18 mg per day.27

In earlier than and after testing, these taking astaxanthin skilled a optimistic impact on their triglyceride and HDL ranges that correlated with elevated adiponectin, a protein that regulates glucose present in fats tissue.28 Astaxanthin can also be a potent preventive and remedy for age-related macular degeneration, which is the most typical reason behind blindness within the aged.29

Astaxanthin demonstrates the power to guard retinal cells from oxidative stress in lab research.30 A assessment of the literature suggests astaxanthin could also be efficient within the prevention and remedy of a number of ocular ailments, “together with diabetic retinopathy, age-related macular degeneration, glaucoma and cataract.”31

Research have additionally delved into astaxanthin’s results on most cancers. Each in vivo and in vitro preclinical antitumor results have been demonstrated in varied most cancers fashions. In keeping with a research printed in 2015, astaxanthin:32

“… exerts its anti-proliferative, anti-apoptosis and anti-invasion affect by way of completely different molecules and pathways together with sign transducer and activator of transcription 3 (STAT3), nuclear issue kappa-light-chain-enhancer of activated B cells (NF-κB) and peroxisome proliferator-activated receptor gamma (PPARγ). Therefore, [astaxanthin] exhibits nice promise as chemotherapeutic brokers in most cancers.”

Antioxidant Calms the Cytokine Storm

The extent of the advantages of this highly effective antioxidant are nonetheless being found. Within the latest COVID-19 pandemic, researchers have discovered indications that justify the potential for together with pure astaxanthin together with different remedies to profit folks with COVID-19.

A latest paper printed on the analysis library web site SSRN discovered the distinctive molecular construction of astaxanthin permits it to penetrate cell membranes and quench reactive oxygen species and free radicals on the inside and outer layer of the membrane. This supplies superior safety towards oxidative stress. The scientists wrote:33

“Clinically, pure astaxanthin has proven various advantages with glorious security and reported to dam oxidative DNA injury, lowered C-reactive protein (CRP) and different irritation biomarkers. Earlier research reported that pure astaxanthin exert optimistic results in assuaging cytokine storm, acute lung harm, acute respiratory syndrome, and so forth …

Present understandings based mostly on accrued evidences counsel that SARS-CoV-2 induces a possible amplified inflammatory response to sequential penalties of ALI [acute lung injury], ARDS [acute respiratory distress syndrome] to a life-threatening dire consequence of potential septic shock with elevated expression of inflammatory associated genes together with inevitable secondary infections, relatively than elevated viral load …

… the attenuation of the cytokine storm by concentrating on key steps within the course of could ship improved outcomes … Shi et al. prompt a two-phase method for potential remedies of COVID-19 sufferers: the primary immune defense-based protecting section for non-severe COVID-19 instances and the second, inflammation-driven damaging section for extreme COVID-19 sufferers.”

In keeping with the authors, astaxanthin could also be uniquely suited to the duty of defending cells towards SARS-CoV-2. The scientists checklist a number of pathways astaxanthin is understood to work that might successfully inhibit a cytokine storm in extreme COVID-19. They wrote that astaxanthin:34

“… with its confirmed anti-inflammatory and anti-oxidant exercise backed by a number of preclinical and human trials and with its extraordinary security profile will be one of the crucial promising candidates to be tried towards COVID-19.

Taken collectively, we speculate that implications of astaxanthin as adjunctive countermeasure within the remedy of COVID-19 could exert twin function of each as antioxidant and anti inflammatory compound with helpful final result of scale back fatality and speedy restoration …”

In brief, astaxanthin ticks many essential containers to ameliorate COVID-19, together with immune response regulation and the enhancement of each cell-mediated and humoral immune responses. You’ll discover extra in my article, “Astaxanthin Helps Alleviate Cytokine Storm.”
