WEEK 15 (2024) – Why Astaxanthin is Your New Must-Have Supplement?

Welcome to this week’s edition of Naturally Healthy News, where we delve into the wonders of Astaxanthin, one of nature’s most potent antioxidants. You may have seen it hit the headlines recently, as reports have dubbed it the ‘miracle’ supplement and questioned whether it is one we should all be taking. Studies link it to wide-ranging benefits, including eye, skin, and brain health. Therefore, this week, we’ll take a closer look at astaxanthin and its many research-backed benefits. Plus, why it is a beneficial compound to include in your daily skincare routine, especially during the sunnier months of the year.

What is Astaxanthin?

Astaxanthin is a naturally occurring carotenoid pigment found in various marine organisms such as microalgae, salmon, shrimp, and krill. It belongs to the xanthophyll family of carotenoids, known for their powerful antioxidant properties. Astaxanthin gives salmon and flamingos their pinkish-red hue, acting as a shield against oxidative stress caused by environmental factors.

How Does Astaxanthin Work?

Astaxanthin exerts its potent antioxidant effects through several key mechanisms, making it a standout among antioxidants. Its unique molecular structure allows it to span cell membranes, reaching both the water-soluble and fat-soluble parts of cells, unlike many other antioxidants. This broad cellular access enables astaxanthin to neutralise a wide range of free radicals, including reactive oxygen species (ROS) and reactive nitrogen species (RNS), which are byproducts of normal cellular metabolism and environmental stressors like UV radiation and pollution. By scavenging these free radicals, astaxanthin helps prevent oxidative damage to lipids, proteins, and DNA within cells, thereby preserving cellular integrity and function.

Furthermore, astaxanthin can activate the body’s own antioxidant defence systems. It upregulates the expression and activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase, which work synergistically to combat oxidative stress. This dual action of direct free radical scavenging and enhancing our own antioxidant defences reinforces its potent antioxidant properties.

Additionally, astaxanthin possesses anti-inflammatory properties that complement its antioxidant actions. Chronic inflammation is closely intertwined with oxidative stress, and astaxanthin helps mitigate inflammatory responses by inhibiting pro-inflammatory cytokines and signalling pathways. This anti-inflammatory effect improves overall tissue protection and supports a balanced immune response.

Research-Backed Benefits

Numerous studies have highlighted the diverse health benefits of astaxanthin, making it a sought-after supplement for maintaining overall health and well-being:

Skin Health: Clinical studies have demonstrated astaxanthin’s remarkable benefits for skin health, particularly in protecting against UV-induced damage and improving overall skin appearance. Research published in the Journal of Clinical Biochemistry and Nutrition found that astaxanthin supplementation significantly reduced UV-induced skin erythema (redness) and improved skin elasticity in human subjects. Another study published in the Journal of Dermatological Science reported that astaxanthin supplementation reduced wrinkles and age spots while improving skin moisture content and texture. These findings highlight astaxanthin’s potential as a natural supplement to support ‘beauty from within’ and maintain youthful and healthy skin.

Eye Health:
Astaxanthin’s protective effects extend to eye health, with studies showcasing its potential in preventing age-related vision problems and supporting overall ocular function. A randomised, double-blind, placebo-controlled trial published in the Journal of Clinical Biochemistry and Nutrition evaluated the effects of astaxanthin supplementation on visual function in healthy subjects. The results showed improvements in visual acuity, contrast sensitivity, and focus in the astaxanthin group compared to the placebo group. Additionally, astaxanthin’s antioxidant properties help protect retinal cells from oxidative stress, making it a promising supplement for preserving eye health.

Brain Function:
Emerging research suggests that astaxanthin may benefit cognitive function and neuroprotection. A review published in the Journal Nutrients investigated the effects of astaxanthin supplementation on cognitive function in older adults with mild cognitive impairment (MCI). The results demonstrated improved cognitive performance, including memory and processing speed and protection from age-related neurodegeneration.

Exercise Performance Enhancement: Clinical research highlights astaxanthin’s potential to enhance endurance, reduce muscle fatigue, promote faster recovery, and support overall muscle health. Studies have shown that astaxanthin supplementation can improve cycling time trial performance, reduce lactate levels indicative of muscle fatigue, and accelerate muscle strength recovery following exercise-induced damage. Its antioxidant properties protect muscles from oxidative stress and inflammation, contributing to improved exercise tolerance and performance. Furthermore, astaxanthin’s ability to enhance mitochondrial function underscores its role in optimising energy production during physical activity.

Cardiovascular Health:
Clinical research has revealed promising benefits for heart function and vascular health. Studies have shown that astaxanthin supplementation can improve markers of cardiovascular risk, including lipid profiles, blood pressure, and oxidative stress levels. Research published in Diabetes Obesity and Metabolism demonstrated that astaxanthin supplementation reduced LDL cholesterol and triglycerides while increasing HDL cholesterol levels. Moreover, astaxanthin’s potent antioxidant and anti-inflammatory properties help protect blood vessels from damage, improve endothelial function, and reduce inflammation markers associated with cardiovascular diseases.

Astaxanthin Supplements for Skin Protection

In the warmer months, protecting our skin from sun damage becomes a top priority. While sunscreen is a crucial tool in our skincare arsenal, incorporating astaxanthin supplements can provide an added layer of defence against UV-induced skin damage.

Here’s why many people turn to astaxanthin for skin protection:

UV Radiation Defense: Astaxanthin’s ability to scavenge free radicals from UV radiation helps prevent skin cell damage, premature ageing, and sunburn. It complements the protective effects of sunscreen by neutralising oxidative stress within the skin layers.

Collagen Support: Collagen is essential for maintaining skin elasticity, firmness, and hydration. Astaxanthin promotes collagen production and helps preserve existing collagen fibres, contributing to youthful and resilient skin.

Reduction of Inflammatory Responses: Excessive sun exposure can trigger inflammatory pathways in the skin, leading to redness, irritation, and skin damage. Astaxanthin’s anti-inflammatory properties help mitigate these responses, reducing the risk of long-term UV-related skin issues. But always remember to sunbathe safely and not to allow the skin to burn.

Enhanced Skin Moisture: Astaxanthin supports skin barrier function and hydration levels, promoting supple, moisturised skin even in sun-exposed conditions. This can be particularly beneficial for individuals with dry or sensitive skin.

Overall Skin Health: Astaxanthin’s multifaceted benefits extend beyond UV protection, contributing to overall skin health, radiance, and resilience against environmental stressors. It is classed as a ‘beauty from within’ product, a category of nutritional ingredients usually referred to as cosmeceuticals or nutricosmetics.
