Astaxanthin: The Super Antioxidant That Comes From the Ocean

By
Antioxidants play an important role in promoting health by protecting your body from free radicals, which are molecules that interfere with the function of your organs, resulting in damage.1 In this regard, many people do their best to increase their intake of well-known antioxidants such as vitamin C and E, as well as flavonoids from plants. But sometimes, this is simply not enough.2

What if there is a certain antioxidant that trumps everything else? The answer you're looking for isn't found in a vegetable or a fruit, but from deep within the ocean: astaxanthin.

Astaxanthin, commonly called "King of the Carotenoids," is a naturally occurring substance found in a specific type of microalgae, as well as certain seafood. In addition, its red color is responsible for turning the flesh of salmon, crab, lobster and shrimp pink.(3) The research regarding this antioxidant is promising, as it has shown that astaxanthin possesses a variety of health benefits. 

The Best Astaxanthin Comes From Microalgae

You may have seen some astaxanthin supplements sold in your local health store. Be vigilant in reading the product labels because some of them are made using synthetic ingredients. Of course, you want to avoid these products because they're made using petrochemicals obtained from petroleum and natural gas.

If you want real astaxanthin, it must be straight from the source, which is the Haematococcus pluvialis microalgae. This type of algae produces the antioxidant once its water supply dries up, and goes into survival mode to protect itself from sunlight, ultraviolet radiation and low nutrition. Astaxanthin is a result of this process. In addition, there are several foods that contain generous amounts of astaxanthin, mainly seafood that consume the microalgae, such as:4

Astaxanthin is also available in various dosages. If you choose to go the supplement route, I strongly recommend getting the ones made from the Haematococcus pluvialis microalgae, not the ones made from petrochemicals. This ensures that you're getting the legitimate benefits the antioxidant is known for, as well as safeguarding your health.

Studies Regarding the Benefits of Astaxanthin

Astaxanthin is quite possibly one of the most valuable antioxidants you can ever take advantage of. Research about this substance is continually growing, and the results are very promising, such as:5

•Improved Antioxidant Profile — One standout feature of astaxanthin is that it is 550 times stronger than vitamin E and 6,000 times more potent than vitamin C. In addition, it is 10 times more effective than zeaxanthin, lutein, canthaxanthin and beta-carotene.6

Research has shown that this antioxidant may benefit your health in important ways. In one example, astaxanthin exhibited digestive-protective properties in rats affected with gastric ulcers.7

•Hearing Protection — Astaxanthin may benefit your hearing by raising your neurotrophin-3 (NT3) levels, a protein that plays a role in the communication between your ears and your brain. A study was able to support this hypothesis when researchers discovered that astaxanthin helped reverse hearing loss in mice.8

•Management of Diabetes — Researchers suggest that astaxanthin may benefit diabetics by reducing oxidative stress in their pancreatic cells caused by high blood sugar levels, as well as improve glucose and serum insulin levels.9

•Reduced Risk of Cardiovascular Disease — Taking astaxanthin regularly may reduce the risk of inflammation in your cardiovascular system.

In one study, participants who took 12 milligrams of astaxanthin per day were able to decrease the presence of C-reactive protein in their body, which is an indicator of inflammation. In another study, Sprague Dawley rats affected with myocardia had a reduced infarct size once astaxanthin was administered.10

•Anticancer Properties — Astaxanthin has been shown to have potential in fighting cancer. Experts believe that the antioxidant works by decreasing mutagenesis and carcinogenesis by inhibiting oxidative damage to cells.

Furthermore, it restores cell-to-cell communication to help decrease tumor proliferation. In one example, astaxanthin exhibited growth-inhibitory effects in human colon cancer cells.11

•Immune System Boost — Your immune system is constantly attacked by free radicals, and astaxanthin can help turn the situation around.

Reports strongly suggest that astaxanthin showed higher immunomodulating effects compared to beta-carotene, as well as enhanced antibody production and decreased humoral immune response.12,13

•Better Eye Health — A few studies suggest that astaxanthin may help protect your eye from various conditions, such as:

◦Cataracts

◦Age-related macular degeneration

◦Glaucoma

◦Inflammatory eye diseases

◦Diabetic retinopathy

•Neuroprotective Effects — Several studies suggest that astaxanthin may be a powerful tool in maintaining brain health, thanks to its anti-inflammatory and antioxidant properties. In one example, 10 elderly participants who took 12 milligrams of astaxanthin daily for 12 weeks displayed improved cognitive and psychomotor function.14

Side Effects of Astaxanthin Are Practically Nonexistent

Side effects of astaxanthin may include slight reddening of the skin, increased bowel movements and red stool color. High doses of astaxanthin may cause stomach pain (R).

In any case, please visit a doctor before taking the supplement.

Astaxanthin Supplements Can Benefit Most People, but Consuming It Naturally May Be Better

Based on published data, it's clear that astaxanthin has strong potential for helping optimize your health in a convenient manner when taken as a supplement. However, it may be more beneficial to consume astaxanthin using a natural approach via the foods where it is commonly found.

For example, wild-caught Alaskan salmon is one of the most nutritious foods you can add to your diet. Aside from astaxanthin, it is rich in omega-3 fatty acids that can provide a wealth of benefits to your overall well-being, such as decreased risk of coronary heart disease and arrhythmia. Almost anyone can benefit from omega-3 fatty acids, as it is an essential nutrient that must be obtained through your diet. Going with a natural approach is essentially hitting two birds with one stone.

As of May 2024, there are more than 4,000 early treatment studies  that have been published and shared with the whole world. New ones are being added every day.  This is a review of the literature, covering multiple observational studies, randomized controlled trials and references related to natural supplements and cytokine storm with more than 300 studies and references. We know that while a large percentage of the population only experiences mild to moderate symptoms of COVID-19 and won’t require hospitalization, others experience severe symptoms and complications, require hospitalization, or may even die.  It appears one of the differences between those who have a mild illness and severe illness is related to the body's ability to reduce the hyperimmune response that leads to a cytokine storm and the hyper-coagulability (tendency for blood clots) that often accompanies it. The cytokine storm may be one possible way to explain the

Dr. Zelenko's Z-Stack Vitamin Cocktail: Review 2024

By

The  Zelenko COVID-19 Protocols  was developed by Dr Vladimir Zelenko. The protocol has as its centerpiece, but not exclusive piece, the combined use of Hydroxychloroquine (HCQ) and Zinc as a means by which a person can both help to prevent or mitigate the contraction of  COVID-19 , or can actually treat the disease once it has been diagnosed.  A  retrospective study  analyzing Dr Zelenko's patient data was accepted for publication after a rigorous peer review process. The study finds that early intervention and treatment of high-risk patients with COVID-19 resulted in significantly fewer hospitalizations and deaths. The treatment consisting of zinc, low-dose hydroxychloroquine (HCQ), and azithromycin, is also referred to as "The Zelenko Protocol." Dr Zelenko has since updated his protocols to incorporate new evidence. He has since evolved his protocols to include a quercetin, zinc, vitamin D and C protocol for low-risk patients as w

10 Best NMN Supplements (2024 Review)

By

NMN stands for nicotinamide mononucleotide and is a precursor to NAD+, or nicotinamide adenine dinucleotide. NMN is the direct precursor of the essential molecule nicotinamide adenine dinucleotide (NAD+) and is considered a key component to increase NAD+ levels in cells. NAD+ is a critical molecule found in every cell of your body, but levels of NAD+ naturally fall with age, making it — and NMN, as a result — crucial. NMN is one of the most popular supplements in the anti aging community. The global Nicotinamide Mononucleotide (NMN) market was valued at US$ 98.5 million in 2019 and it is expected to reach US$ 296.5 million ( R ) by the end of 2026, growing at a CAGR (Compound Annual Growth Rate) of 7.3% during 2021-2026. The NAD story took off toward the end of 2013 with a  high-profile paper  by Harvard's David Sinclair and colleagues. Sinclair, recall, achieved fame in the mid-2000s for research on yeast and mice that suggested the red wine ingredient resvera
