Looking for new ways to find the right balance of nutrients in natural foods? Zeaxanthin and astaxanthin are two more things to add to the list. Both are made from plants, have a lot of antioxidants, and are good for your health in many different ways. Astaxanthin, which comes from algae and is a powerful terpine, is in GEM’s Daily Essentials multi-bite. But what’s the difference between zeaxanthin and astaxanthin
Zeaxanthin vs. Astaxanthin: Color Variations and Origin Differences
Zeaxanthin is a pigment that gives plants and vegetables their yellow colour. It is found in corn, cantaloupe, and carrots, among other things. Even though it looks different, zeaxanthin is the most common yellow pigment (xanthophyll) in dark green leafy vegetables like kale, spinach, and broccoli.
Zeaxanthin is another one of the most common carotenoids in nature. Plants and some microorganisms make it. Many people eat a lot of fruits and vegetables to meet their needs. So, what is astaxanthin, and how is it different? Natural astaxanthin is a powerful antioxidant that has been called the “king of the carotenoids.” Salmon is a beautiful colour because it has a red-orange pigment in it. GEM gets astaxanthin from the Himalayas in a way that is good for the environment and climate. This is where Haematococcus pluvialis, the microalgae that contains astaxanthin, grows best. Even though it is most common in algae, it can also be found in salmon, trout, and other fish, as well as in shellfish.
Benefits of Zeaxanthin
One of the biggest differences between zeaxanthin and astaxanthin is that only zeaxanthin and lutein are stored in the retina. So, it’s mostly good for eye health because it keeps the eyes from getting inflamed and hurt by free radicals.
A zeaxanthin supplement also acts as a natural block against absorbing too much light energy, both from the sun’s UV rays and from the blue light that electronic devices give off. A zeaxanthin supplement may help with a number of eye conditions and diseases, such as eye strain and ageing, uveitis, macular degeneration, cataracts, and diabetic retinopathy.
Zeaxanthin for Eye Health
Because we use screens so much, people of all ages often have tired eyes and the pain that comes with it. As a result, progressive eye strain can cause headaches, dry eyes, eye fatigue, blurred vision, and neck and shoulder strain.
Researchers at Fordham University say that zeaxanthin helps block the blue light that these screens give off and protects the eye tissues from damage caused by singlet oxygen. The results of their research also showed that this carotenoid helps lower the risk of blindness that can’t be fixed.
Zeaxanthin for Uveitis
Uveitis is a broad term for inflammation in the eye that can affect different parts of the eye. Researchers from the University of Texas Medical Branch in Galveston study the effects of several antioxidants as a way to reduce inflammation in the eye. Their research shows that carotenoids protect against free radicals and help control inflammation caused by oxidative stress.
Zeaxanthin for Macular Degeneration
Macular degeneration is common in older people and can lead to blindness in the end. Researchers at Peking University in Beijing, China, found evidence that suggests eating more zeaxanthin and lutein may protect against late macular degeneration.
A separate study done by the Departments of Ophthalmology and Visual Sciences shows that healthy women younger than 75 whose diets are high in these carotenoids may be less likely to get intermediate macular degeneration.
Zeaxanthin for Cataracts
Cataracts are another common eye problem that tends to happen as people get older. A study done at the University of Melbourne in Australia found that eating a lot of lutein-zeaxanthin was linked to a lower risk of getting cataracts. More research shows that eating a lot of zeaxanthin-rich vegetables may help prevent cataracts or slow their growth in people who already have them.
Zeaxanthin for Diabetic Retinopathy
Retinopathy is an eye disease that makes it hard or impossible to see. A study from the Kresge Eye Institute in Detroit, Michigan, talks about how too much damage from oxidation can lead to diabetic retinopathy. Results showed that diabetic patients who took zeaxanthin supplements had a lot less damage and a higher level of vascular endothelial cell growth factor, which could stop retinopathy from happening.
Benefits of Astaxanthin
Zeaxanthin has mostly been shown to help with eye health, but astaxanthin has a wider range of health benefits. It has also been shown to protect the eyes, as well as the heart, skin, joints, cancer treatment, and the immune system’s responses.
Astaxanthin for Heart Health
Astaxanthin is known for its ability to reduce inflammation and help keep the heart healthy. Australian researchers found evidence that this dietary supplement helped reduce blood clots, plaque buildup, fatty acids, and blood pressure. More research from the National Institute of Health and Nutrition in Tokyo suggests that astaxanthin could help prevent atherosclerosis, which is a buildup of plaque that can lead to serious heart conditions like angina and myocardial infarction. This study shows that astaxanthin is also a great natural supplement that can help prevent heart disease.
Astaxanthin for Skin
When algae is used as a topical solution, it is known to be good for your skin. The benefits of astaxanthin in food, on the other hand, help skin health from the inside out. When taken as a chewable, astaxanthin has been shown to reduce age spots, wrinkles, and fine lines. It does this by blocking the sun’s ageing effects and stopping the loss of water that leads to dry, rough skin tone and texture.
Astaxanthin for Joint Protection
As with eye strain, joint pain and inflammation are happening more and more these days. Texting, scrolling, and typing can keep your hands and forearms moving all day, which can lead to tension and stiffness.
It has also been shown that taking an astaxanthin supplement can reduce the pain and joint damage caused by conditions like carpal tunnel syndrome and osteoarthritis. Research shows that it could help lessen the effects of joint pain because it reduces oxidative stress and reduces inflammation.
Astaxanthin for Regulates Immune Responses
Astaxanthin is also good for you because it can help control how your immune system responds. A study done by Inha University in Korea, La Haye Labs, Inc. in Redmond, and Washington State University showed that people who took two or eight mg of astaxanthin every day for eight weeks had less inflammation and oxidative damage, and in the first four weeks, a DNA damage marker went down.
Zeaxanthin vs. Astaxanthin: Which Is Better
Even though it’s safe to say that both zeaxanthin and astaxanthin are good for your health, astaxanthin has more of them. In general, eating a lot of fruits, vegetables, and algae helps the body absorb more carotenoids, which helps keep the body in good health overall.
Gaining Value from Natural-Based Nutrition
As different as zeaxanthin and astaxanthin are, their similarities are also important. Both zeaxanthin and astaxanthin are made by plants and are carotenoids. They also have helpful antioxidant properties. Antioxidants are good for a healthy, well-balanced diet that helps protect against free radicals and oxidative stress.
