Astaxanthin VS Zeaxanthin

What's the Difference Between Zeaxanthin and Astaxanthin?

Exotic foods are becoming increasingly popular as individuals seek natural ways to achieve nutritional balance. Zeaxanthin and astaxanthin are the most recent additions to the list. Both are plant-based cartoneids that are high in antioxidants and have a long list of health advantages. What is the difference between zeaxanthin and astaxanthin, on the other hand?

When comparing the two, it's necessary to give an overview of each so that you can see how and why these elements are used. We're going to talk about the differences in benefits provided by both of these potent components. You'll have a better notion of which dietary supplement is suitable for you by the end of this essay.

Variations in color and differences in origin

Zeaxanthin is a yellow pigment present in a variety of plants and vegetables, including corn, cantaloupe, and carrots. Despite its distinctive appearance, zeaxanthin is the most prevalent xanthophyll (yellow pigment) found in dark green leafy vegetables such as kale, spinach, and broccoli.

It's one of the most prevalent carotenoids found in nature, and it's made by plants and some microbes. Many people get their daily allowance by eating a diet rich in fruits and vegetables.

So, what is astaxanthin and how does it differ from other antioxidants? Because of its high antioxidant content, natural astaxanthin is known as the "monarch of the carotenoids." 2 Salmon has a reddish-orange pigment that gives it its attractive color. Astaxanthin is sourced from the Himalayas, where the natural environment and climate are excellent for cultivating Haematococcus pluvialis, the astaxanthin-producing microalga. Although it is most prevalent in algae, it can also be found in salmon, trout, and a variety of shellfish.

Zeaxanthin's Advantages

One of the most significant differences between zeaxanthin and astaxanthin is that zeaxanthin is the sole carotenoids that accumulate in the retina, along with lutein. As a result, it protects the eyes from inflammation and free radicals, which is helpful to eye health. 

A zeaxanthin pill can also protect you against absorbing too much light energy, such as UV rays from the sun and blue light emitted by electronic devices. A zeaxanthin supplement may aid in the treatment of a number of eye-related ailments and diseases, including:

  • Aging and eye strain
  • Uveitis
  • Cataracts are caused by macular degeneration.
  • Diabetic retinopathy is a type of retinopathy that develops as a result of diabetes.

Pain and strain in the eyes

Eye fatigue and pain are common among people of all ages as a result of our modern world's increased reliance on gadgets. The use of digital screens is considerably more widespread than we'd like to acknowledge, from daily smartphone use to playing video games on the computer. As a result, headaches, dry eyes, eye fatigue, impaired vision, and neck and shoulder strain are common side symptoms of increasing eye strain.

Researchers from Fordham University discuss the benefits of zeaxanthin. It mentions two of the most important types of eye protection it offers. For starters, it aids in the filtering of blue light emitted by electronic devices. Second, it protects the tissues of the eyes from singlet oxygen damage. 3 Their findings also showed that this carotenoid can help reduce the incidence of irreversible blindness.


Uveitis is a broad word for inflammation of the eye that affects various regions of the eye.

5 Researchers from the University of Texas Medical Branch in Galveston look into the effects of a variety of antioxidants to see whether they can help minimize ocular inflammation. Carotenoids, in particular, appear to guard against free radicals and aid in the regulation of oxidative stress-induced inflammation, according to their findings.

Macular Degeneration is a condition that affects the eyes.

Macular degeneration is a condition that affects older people and can lead to eyesight loss. Increased dietary consumption of zeaxanthin and lutein may protect against late macular degeneration, according to researchers at Peking University in Beijing, China.

A further study undertaken by the Departments of Ophthalmology and Visual Sciences also demonstrates that diets high in these carotenoids may protect healthy women under the age of 75 against intermediate macular degeneration.


Cataracts are another prevalent eye ailment that affects people as they get older. The occurrence of cataracts was found to be inversely related to a high dietary intake of lutein-zeaxanthin in a study undertaken by the University of Melbourne in Australia. According to another studies, persons who eat a diet high in zeaxanthin-rich vegetables may be able to prevent cataract formation and/or decrease their progression.

Diabetic Retinopathy is a disease that affects people who have diabetes.

Retinopathy is an ophthalmic condition that causes vision loss and impairment. Excessive oxidative damage as a cause of diabetic retinopathy is discussed in a paper from the Kresge Eye Institute in Detroit, MI. Zeaxanthin administration dramatically reduced damage and increased vascular endothelial cell growth factor, potentially preventing the development of retinopathy in diabetes individuals.

Natural Astaxanthin's Advantages

While zeaxanthin has mostly been shown to help eye health, astaxanthin has a broader range of health advantages. It has also been found to help with heart health, skin care, joint protection, cancer treatment, and immune responses, in addition to protecting the eyes.

Cardiovascular Health

Astaxanthin is well-known for its anti-inflammatory qualities as well as its heart-health benefits. According to Australian experts, this dietary supplement helped to reduce blood clots and plaque accumulation, as well as fatty acid and blood pressure levels. Additional research from Tokyo's National Institute of Health and Nutrition suggests that astaxanthin may help to prevent atherosclerosis, a plaque accumulation that can lead to significant heart problems like angina and myocardial infarction. According to this study, astaxanthin can be a beneficial natural supplement for preventing cardiovascular disease.

Skin Rejuvenation

When applied as a topical treatment, algae is well-known for its skincare benefits. Dietary astaxanthin, on the other hand, helps skin health from the inside out. When taken as a chewable, astaxanthin has been shown to diminish age spots, wrinkles, and fine lines by slowing down the aging effects of the sun and limiting water loss, which causes dry, rough skin tone and texture.

Mutual Defense

Joint soreness and inflammation are now all too common, just as they are with increased eye strain. Tension and stiffness in the hands and forearms can be caused by the constant activity of texting, scrolling, and typing throughout the day.

A dietary supplement containing astaxanthin has also been demonstrated to alleviate pain and joint degeneration in disorders such as carpal tunnel syndrome and osteoarthritis. It has been shown in studies to be useful in reducing the symptoms of joint pain by regulating oxidative stress and reducing inflammation.

Treatment for Cancer

Antioxidant-rich foods are a part of a healthy diet and can aid in the prevention of some malignancies. According to a study conducted by Hong Kong experts, astaxanthin inhibits the growth of malignant cells after a 48-hour incubation period and may even result in cancer cell death after six days.

Immune Responses are regulated.

Another advantage of astaxanthin supplementation is its ability to help modulate immunological responses. A study conducted by Inha University in Korea, La Haye Labs, Inc. in Redmond, and Washington State University found that taking astaxanthin daily (at two or eight mg) for eight weeks reduced inflammation and oxidative damage in study participants while also lowering a DNA damage marker within the first four weeks.

Though both zeaxanthin and astaxanthin are thought to provide a variety of health benefits, astaxanthin's are more numerous. A diet rich in fruits, vegetables, and algae, in general, helps to enhance the quantity of carotenoids absorbed by the body, which aids in overall health.

Getting the Most Out of Natural-Based Nutrition

There's value in how zeaxanthin and astaxanthin are similar as well as how they're different. Both zeaxanthin and astaxanthin are carotenoids that are generated by plants and have beneficial antioxidant effects. Antioxidants help to maintain a healthy diet by protecting against free radicals and oxidative stress.

Free radicals can be found in the environment, as a result of air pollution, some poisons and chemicals, a high-carbohydrate diet, and other factors that might cause cell damage. The activity that arises from the development of these free radicals in the body is known as oxidative stress. Diabetes, cancer, eye problems, Alzheimer's, and Parkinson's are just a few of the diseases it's been linked to.

6 For decades, doctors and medical professionals have advised individuals to eat a diet rich in fruits and vegetables as a preventative measure against these harmful events.

However, not everyone can meet their required daily vitamin, mineral, and antioxidant intake alone through diet. Additionally, many people are experiencing pill weariness as a result of the additional supplementation needed to attain these daily values. Fortunately, GEM offers a natural, allergen-free alternative that allows people to reap the benefits of nutritious, non-synthetic components in the form of a chewable food.

What we eat has a direct impact on our appearance, feeling, and function. Taking advantage of the readily accessible sustainable components aids in the maintenance of proper nutrition and bodily balance. Our diets don't always provide us with what we require for our bodies to thrive. Our antioxidant supplementation can help you boost cognitive performance, minimize oxidative damage, and protect your eye health. In just one bite, you can obtain all of the nutrients you need with ingredients you recognize.
