- ضدآفتاب in a pill?
- Prevention of wrinkles, پوست خشک, age spots and freckles?
- Reversing the visible signs of aging?
If you think checking “all of the above” seems too good to be true, تو تنها نیستی.
But there just happens to be a natural compound that clinical studies are suggesting does ALL of the above—without a hefty price tag or side effects. This is a little miracle your plastic surgeon won’t want you to hear about.
It’s a relatively unknown carotenoid called آستاگزانتين, which is now believed to be the most potent antioxidant nature has to offer.
Scientists long ago discovered that a class of naturally occurring pigments called carotenoids held powerful antioxidant properties that are crucial for your health. Carotenoids are the compounds that give foods their vibrant colors—from green grasses to red beets, to the spectacular yellows and oranges of your bell peppers.
There are more than 700 naturally occurring carotenoids, but most people are familiar with only a few. همین الان, you probably have about ten different carotenoids circulating through your bloodstream.
As a source of antioxidants and vitamin A, carotenoids are critical to the photosynthetic process and protect a plant or organism from damage by light and oxygen. By consuming plants or organisms that contain these pigments, you gain a similar protective benefit.
آستاگزانتين has recently jumped to the front of the line in terms of its status as a “supernutrient,” becoming the focus of a large and growing number of peer-reviewed scientific studies.
One of the benefits of آستاگزانتين that has piqued the interest of researchers is its ability to help protect your skin from the sun, reducing the signs of aging.
اما, ataxanthin’s benefits to your health are more than skin deep—در واقع, so many benefits that I’ve had to write several articles just to cover the jaw-dropping activities of this amazing nutrient.
آستاگزانتين is in a League of Its Own
آستاگزانتين is produced only by the microalgae Haematococcus pluvialis when its water supply dries up, forcing it to protect itself from ultraviolet radiation. It’s the algae’s survival mechanism—آستاگزانتين serves as a “force field” to protect the algae from lack of nutrition and/or intense sunlight.
It is this “radiation shield” that underlies how آستاگزانتين can help protect you from similar radiation.
Many carotenoids are easily obtainable through a good diet rich in fresh organic produce. اما, this powerful carotenoid is harder to come by. There are only two main sources of آستاگزانتين—the microalgae that produce it, and the sea creatures that consume the algae (such as salmon, shellfish, and krill).
آستاگزانتين is the reason salmon have the strength and endurance to swim up rivers and waterfalls for days on end—their diets are high in this pigment, which concentrates in their muscles and makes them one of the “kings of endurance” of the animal kingdom.
This pigment is the most commonly occurring red carotenoid in marine and aquatic animals and is what gives salmon and pink flamingos their characteristic pink color. Most people don’t realize that baby flamingos are actually white and don’t turn pink until they receive آستاگزانتين, primarily from shrimp and algae.
آستاگزانتين is leaps and bounds more powerful than بتا-کاروتن, alpha-tocopherol, lycopene and lutein, other members of its chemical family. It exhibits VERY STRONG free radical scavenging activity and protects your cells, organs and body tissues from oxidative damage.
آستاگزانتين’s unique “antioxidative artillery” provides for an impressive array of health benefits, including improving cardiovascular health, stabilizing blood sugar, boosting your immune system, fighting cancer, reducing inflammation, improving eye health—and even improving your athletic abilities.
What Makes آستاگزانتين Special?
There are many properties that make this carotenoid unique. Here are the main differences:
- آستاگزانتين is by far the most powerful carotenoid antioxidant when it comes to free radical scavenging: آستاگزانتين است 65 times more powerful than vitamin C, 54 times more powerful than بتا-کاروتن, و 14 times more powerful than vitamin E.
- آستاگزانتين is far more effective than other carotenoids at “singlet oxygen quenching,” which is a particular type of oxidation. The damaging effects of sunlight and various organic materials are caused by this less-stable form of oxygen. آستاگزانتين است 550 times more powerful than vitamin E و 11 times more powerful than بتا-کاروتن at neutralizing singlet oxygen.
- آستاگزانتين crosses the blood-brain barrier AND the blood-retinal barrier (beta carotene and lycopene do not), which brings antioxidant and anti-inflammatory protection to your eyes, brain and central nervous system and reduces your risk for cataracts, macular degeneration, blindness, dementia and Alzheimer’s disease.
- آستاگزانتين is soluble in lipids, so it incorporates into cell membranes.
- It’s a potent UVB absorber and reduces DNA damage.
- It’s a powerful natural anti-inflammatory.
And how about some more great news? There have been no adverse reactions found for people taking آستاگزانتين.
Sunburn is Inflammation
If you are physically active, you have probably spent a fair amount of time in the sun. The sun offers enormous benefits to you in terms of vitamin D. But too much of a good thing can be—well, too much of a good thing.
Many athletes complain of feeling ill from overexposure to the sun after long trainings outside. اما, many report آستاگزانتين has allowed them to stay in the sun for longer periods of time, without feeling ill and without burning. Less burning also means lower skin cancer risk.
How does it do this?
The answer lies in how the Haematococcus pluvialis protects itself from intense ultraviolet radiation by producing آستاگزانتين as a natural ضدآفتاب. When you consume this pigment, you are creating your own “internal ضدآفتاب.” In other words, the same powerful antioxidants that protect the algae from the sun’s rays can help protect YOU as well.
Sunburn is actually an inflammatory process. Although the exact pathway by which آستاگزانتين protects your skin from burning is not yet known, it is almost certain that its anti-inflammatory properties are involved.
دكتر. Nicholas Perricone and Dr. Robert Childs, a physician in Hawaii, are both fans of آستاگزانتين.
دكتر. Childs, born and raised in Honolulu, was always extremely sensitive to the sun, until he started taking آستاگزانتين. He now finds he can go out in the midday Hawaiian sun for four hours without burning, whereas he used to burn within a half hour. He also discovered that, within a few weeks of starting آستاگزانتين, his morning stiffness and soreness had disappeared.
آستاگزانتين as an Internal ضدآفتاب
Besides copious testimonials and anecdotal evidence, scientific studies have substantiated these skin protective effects.
Cyanotech Corporation funded a study through an independent consumer research laboratory to measure the skin’s resistance to both UVA and UVB light, before and after آستاگزانتين supplementation.
The result was that in only three weeks of taking 4mg per day, subjects showed a significant increase in the amount of time necessary for UV radiation to redden their skin.
Animal studies lend further evidence to آستاگزانتين’s effects as an internal ضدآفتاب.
Consider the following:
- In 1995, hairless mice were fed various combinations of آستاگزانتين, بتا-کاروتن and retinol for four months. After irradiation, آستاگزانتين alone or in combination with retinol was substantially effective in preventing photoaging of the skin (as measured by markers for skin damage). [Savoure, N., Briand, G., Amory-Touz, M., Combre, A., Maudet, M. (1995). “Vitamin A status and metabolism of cutaneous polyamines in the hairless mouse after UV irradiation: action of بتا-کاروتن و آستاگزانتين.” International Journal for Vitamin and Nutrition Research. 65(2):79-86.]
- In a 1998 study with rats, آستاگزانتين was found to be 100 times stronger than بتا-کاروتن و 1000 times stronger than lutein in preventing UVA light-induced oxidative stress.
- The Journal of Dermatological Science published a study in 2002 finding آستاگزانتين is able to protect against alterations in human DNA induced by UVA light exposure.
A Topical Paradise: Help in Preventing Collagen Damage, چروک, Freckles and Age Spots
ولی آستاگزانتين might not even need to be ingested in order to protect you from the sun. In 2001, Arakane performed a study on hairless mice to explore whether or not آستاگزانتين offered topical benefits.
The mice were exposed to UVB radiation for 18 weeks to simulate photo-aged skin. The mice that had آستاگزانتين applied to their skin demonstrated reduced wrinkles when compared to the control group, as well as younger-appearing collagen. در واقع, the collagen of the آستاگزانتين mice looked as if it had never been exposed to radiation.
Researchers concluded that آستاگزانتين “can significantly prevent UV-induced collagen degradation, چروک, lipid peroxidation, آفتاب سوختگی, phototoxicity and photoallergy.”
The same study also discovered that topical آستاگزانتين can act as an effective “skin whitening agent,” which is a tremendously popular trend in Asia. آستاگزانتين was found to reduce melanin by 40 percent, greatly reducing freckles and age spots.
Beauty From Within
Although it appears that آستاگزانتين does indeed offer topical benefits, your greatest gifts will come from taking آستاگزانتين internally.
There have been three studies demonstrating that taking آستاگزانتين can improve the way you look. All of these studies combine آستاگزانتين with other substances, such as omega-3 fatty acids or vitamin E, but all three had positive findings when آستاگزانتين was present.
- In Japan, a study was done in 2002 by Yamashita with women around age 40 who consumed 2mg آستاگزانتين daily for four weeks. Researchers were surprised that after only 2 هفته, almost every aspect of the women’s skin had improved; پس 4 هفته, there was even more improvement. [Yamashita, ابراهيم. (2002). “Cosmetic Benefit of Dietary Supplements Containing آستاگزانتين and Tocotrienol on Human Skin.” Food Style. 21 6(6):112-17]Benefits included fewer fine lines, better moisture, increased skin tone and elasticity, smoother surface, fewer freckles, and less under-eye puffiness.
- In 2003 a Canadian study involving female subjects ages 35 به 55 were given آستاگزانتين combined with omega-3 fatty acids and marine glycosaminoglycans. They were divided into three groups using different combinations of these agents, all showing improvements in the areas measured.
Due to the design of the study, researchers were limited in the conclusions they could draw, but said it was clear that آستاگزانتين does offer benefits as an internal beauty supplement.- The third study was done in Europe and was similar to the Japanese study discussed above. اما, subjects were given 5mg per day آستاگزانتين along with two other ingredients. Treated subjects showed improvements in fine lines, an increase in dermis density of up to 78 percent, and visible improvement in overall skin appearance.
Can Eating Colorful Vegetables Make You MORE Attractive and Help Snag You a Mate?
One of the most interesting studies to date was headed by Dr. Ian Stephen at the University of Nottingham who investigated what skin tones were perceived as most healthy and attractive to humans.
He discovered that red and yellow skin tones make you more attractive.
People take on redder tones when they are flushed with blood, particularly if the blood has lots of oxygen in it, and from a biological/anthropological perspective, this signals health and vitality.
Scientists have believed that we evolved by selecting potential mates whose appearance signaled good health. According to coauthor of the study, David Perrett, PhD:
“This is something we share with many other species. به عنوان مثال, the bright yellow beaks and feathers of many birds can be thought of as adverts showing how healthy a male bird is. چه بیشتر, females of these species prefer to mate with brighter, more colored males. But this is the first study in which this has been demonstrated in humans.
Together our studies link skin carotenoid coloration to both perceived health and healthy diet, establishing carotenoid coloration as a valid cue to human health which is perceptible in a way that is relevant to mate choice, as it is in bird and fish species.”
Healthier Looking Than a Tan !!
And here’s the kicker…
دكتر. Stephen found that, given the choice between skin color caused by suntan and skin color caused by carotenoids, people preferred the carotenoid skin color.
So if you want to be more physically attractive, make sure you use a regular source of آستاگزانتين. Not only will it allow you to look healthier it will also help protect you when you are tanning and optimizing your vitamin D levels.
Make Sure Your آستاگزانتين is the Natural Variety from Marine Algae—NOT Synthetic
Synthetic (laboratory-made) آستاگزانتين is now commonly used worldwide to supplement fish feeds in order to obtain the desired pinkish to orange-red color. You really should avoid synthetic آستاگزانتين because it’s made from petrochemicals.
Some aquaculture companies are beginning to use natural آستاگزانتين instead of synthetic, even though it costs more, because it’s better for the health of the animals, and it’s far superior for pigmentation. Animals fed fish food with natural آستاگزانتين have higher survival rates, better growth rates, better immunity, fertility and reproduction.
متاسفانه, synthetic آستاگزانتين still dominates the farmed salmon industry worldwide.
If your salmon label does not read “wild” or “naturally colored,” you’re probably going to be eating a coloring agent somewhat closer to motor oil than antioxidant. طبیعی آستاگزانتين is more than 20 times stronger as an antioxidant than synthetic آستاگزانتين.
Wild salmon are 400 percent higher in آستاگزانتين than farmed salmon, and100 percent of their pigment is natural آستاگزانتين, rather than synthetic. پلاس, wild salmon have much higher levels of omega-3 fatty acids than the farmed version. But even if you are successful in purchasing genuine wild salmon, there is the problem with high levels of mercury and other unwanted toxins, not to mention the skyrocketing prices.
Final Recommendations
If you decide to give آستاگزانتين امتحان کنید, I recommend starting with at least 2 mg per day. I have been taking 8 mg per day this year. Krill has some آستاگزانتين in it, but not enough to provide full benefits.
