What are the health benefits of astaxanthin?
Astaxanthin is a naturally occurring carotenoid pigment found in certain types of algae, as well as in seafood like salmon, shrimp, and lobster. It is a red pigment that gives these organisms their distinctive colour.
It’s known for its many incredible health benefits, including reducing inflammation, improving skin health, promoting cardiovascular health, and protecting eye health. In this article, we take an in-depth look at these health benefits as well as things to consider before incorporating an astaxanthin supplement into your diet.
Astaxanthin’s health benefits
Astaxanthin possesses powerful antioxidant properties and has been linked to numerous health benefits, including reducing inflammation, improving skin health, and promoting cardiovascular health.
Astaxanthin functions as an antioxidant by neutralising free radicals in the body. Free radicals are unstable molecules that can cause oxidative stress and damage to cells, leading to a range of health problems, including inflammation, ageing, and chronic diseases like cancer and cardiovascular disease. By neutralising free radicals, antioxidants can help to reduce inflammation and protect cells from damage, promoting optimal health.
Astaxanthin is a particularly effective antioxidant because it can cross both the blood-brain barrier and the blood-retinal barrier, meaning that it can protect the brain and eyes from oxidative stress.
Various studies have been published by institutions such as the Journal of Agricultural and Food Chemistry as well as the Journal of Medicinal Food that have scientifically shown the antioxidant properties of astaxanthin as well as its health benefits.
Astaxanthin is also a potent, naturally occurring compound that has been shown to reduce inflammation in the body. It does this by modulating the activity of several inflammatory pathways, including nuclear factor kappa B (NF-κB) and tumour necrosis factor-alpha (TNF-α).
When inflammation occurs, it can lead to various chronic diseases, such as diabetes, heart disease, and arthritis. By reducing inflammation in the body, astaxanthin may help prevent or mitigate these conditions. Additionally, astaxanthin has been found to support immune function, promote healthy skin, and improve exercise performance.
Several scientific studies have demonstrated the anti-inflammatory properties of astaxanthin. In one study, astaxanthin supplementation was found to decrease levels of inflammatory markers in patients with non-alcoholic fatty liver disease. Another study found that astaxanthin reduced inflammation and improved joint function in patients with rheumatoid arthritis. Additionally, a meta-analysis of several studies concluded that astaxanthin could reduce oxidative stress and inflammation in healthy individuals.
Improved Cardiovascular Health
Astaxanthin, a natural carotenoid found in seafood, has been shown to have beneficial effects on cardiovascular health by reducing oxidative stress and inflammation, improving cholesterol levels, and enhancing blood flow.
Oxidative stress and inflammation are two major contributors to the development of cardiovascular diseases. Astaxanthin's potent antioxidant and anti-inflammatory properties can help protect against these risk factors by neutralising harmful free radicals and reducing inflammation.
Improving cardiovascular health has numerous benefits, including reducing the risk of heart attack, stroke, and other cardiovascular diseases. It can also lead to increased energy levels, better sleep, and improved overall quality of life.
Several scientific studies have demonstrated the beneficial effects of astaxanthin on cardiovascular health. In one study, astaxanthin supplementation was found to improve lipid profile, reducing LDL cholesterol levels and increasing HDL cholesterol levels in overweight and obese individuals. Another study found that astaxanthin reduced oxidative stress and improved endothelial function, which plays a critical role in blood flow and circulation.
Skin Health Benefits
Astaxanthin can protect against sun damage, reduce wrinkles and fine lines, improve skin elasticity and moisture, and reduce inflammation associated with various skin conditions.
Skin health is important not only for appearance but also for protection against external factors such as UV radiation and pollutants. Good skin health can also help prevent skin infections and other skin conditions.
Several scientific studies have demonstrated the beneficial effects of astaxanthin on skin health. One study found that astaxanthin supplementation improved skin moisture content, elasticity, and texture in healthy individuals. Another study found that astaxanthin supplementation reduced the appearance of fine lines and wrinkles in middle-aged women.
Eye Health Benefits
This keto-carotenoid has also been shown to have beneficial effects on eye health by reducing oxidative stress and inflammation, protecting against age-related macular degeneration (AMD), and improving visual function.
Eye health is important for maintaining clear vision and preventing age-related vision loss. Good eye health can also help reduce the risk of eye infections and other eye diseases.
How can Rejuvenated help?
At Rejuvenated, our H30 Night Repair Supplement contains astaxanthin as well as a host of other beneficial ingredients, such as grape seed extract, pine bark and vitamin A.
While taking is generally considered safe when taken as recommended, it can interact with certain medications, including blood thinners, which can increase the risk of bleeding. It may also interact with immunosuppressants and cholesterol-lowering medications.
Additionally, it can cause mild side effects in some people, such as stomach upset, diarrhoea, or skin discolouration. These side effects are generally rare and can be avoided by following recommended dosages.
So, as always, we recommend you consult a healthcare professional before incorporating this or any other supplement into your diet.
