Astaxanthin - The Ultimate Nutrient

Astaxanthin - The Ultimate Nutrient

Astaxanthin may not be a common household name, however it doesn’t make it any less important. Astaxanthin is a vital antioxidant known as the ‘king of the carotenoids’ as its potency is 6 thousand times higher than vitamin C and five hundred times more effective than the antioxidant, vitamin E. Carotenoids are phytochemicals found in an array of plants, bacteria, algae, and many other living organisms. They vary in their natural pigmented colours and are responsible for the vibrant orange, red and yellows, mainly found in vegetables, fruits and herbs.

Astaxanthin is a potent fat soluble carotenoid which provides positive outcomes in many areas of human health.  It has been founded to protect cells against a wide range of illnesses, along with great tolerability and safety. Below we explore 5 powerful benefits of this ultimate nutrient: 

Reduce fine lines & wrinkles

Astaxanthin being a powerful carotenoid is one of the most, if not the most important nutrient dense antioxidants for skin health and healing (1,2). Numerous clinical research suggests oral and topical use has found improvements in facial wrinkles, skin texture, elasticity and age spots. A specific study on men concluded that after 6 weeks of oral supplementation, patients had improved moisture content and more regulated sebum oil level at the cheek zone (3).

Protect against UV damage

Astaxanthin has been shown to protect the body's largest organ. The studies are clear and consistent and show excellent results for helping with skin moisture levels, smoothness, elasticity, fine wrinkles, and spots or freckles. (4, 5). 

Astaxanthin may help support sun damaged skin, caused by ultraviolet rays from the sun. In fact, if you get a sunburn, which causes inflammation, astaxanthin penetrates the skin cells and reduces UVA damage. Think of it as an internal sunscreen (5, 7).

Relieve pain & inflammation

Astaxanthin has been shown to reduce inflammatory pathways including nitric oxide, prostaglandins and C Reactive Protein (CRP), of which CRP is tested as a key indicator for heart disease.  A few studies have noted that patients taking Astaxanthin for 12 weeks or more, showed a significant decrease in their CRP levels, some up to 20% in just 8 weeks (4,6).

Protection of Cardiovascular health

Research has shown that patients who are at high cardiovascular disease (CVD) risk who consistently took astaxanthin orally found a significant decrease in key factors which lead to CVD. These include minimising free radical damage to membranes, increasing circulation and reducing cholesterol accumulation (2). Therefore the use of antioxidant therapies, including that of astaxanthin, may have profound effects on assisting the normal regulation of circulatory systems to reduce the risk of poor cardiovascular outcomes.

May improve eye health

Including the strong properties of astaxanthin listed above, the antioxidant powerhouse also has mighty effects that may help to improve our circulation, particularly with blood and oxygen moving to the capillaries. Meaning, the vascular layers of the eyes are protected by free radical damage as nutrients can easily flow to certain areas, and thus are less at risk of developing diseases that may result in loss of vision (8).
