Astaxanthin – The King of Antioxidants

Allow me to acquaint you with one of nature’s most potent antioxidants – astaxanthin (as-ta-xan-thin) – with the latest research showing promising results for those everyday concerns such as ageing skin, low immunity, tiredness and fatigue, aching joints, low fertility, poor cognitive function, below-par exercise performance – and so much more.

What is astaxanthin?

Astaxanthin is a bright red carotenoid pigment (natural colour) derived from haematococcus pluvialis (H. pluvialis), an algae with the highest levels of astaxanthin, accumulated to protect itself in response to stressors from its environment, such as starvation, high levels of salt, high temperature and radiation. The accumulation of astaxanthin turns the algae from green to red, and is responsible for the bright pink-red colouring of many marine animals such as salmon, crab and lobster and the brightly coloured feathers of flamingos, who obtain astaxanthin through their diet. Aside from its wonderful colouring, its main action is that of an antioxidant and, as such, providing protection to algae from environmental stressors as listed above.

Just as with algae, the human body is also exposed to environmental stressors; however, these lead to the creation of free radicals – for example, from factors such as poor diet, pollution, stress, exercise, smoking, alcohol and medication. Fortunately, the body has its own inbuilt antioxidant capabilities which it works hard to keep in balance. Issues arise, however, when an over-burdened body struggles to keep up, which can lead to oxidative stress and, in turn, cellular damage. Long term, oxidative stress is associated with chronic inflammation, autoimmune conditions, accelerated ageing and hormonal issues.

Astaxanthin can support combat against free radicals

Astaxanthin works in several ways to help to combat free radicals in the human body. Like all antioxidants, astaxanthin donates a chemical group to free radicals (compounds that have lost a chemical group and without it become unstable and lead to oxidative damage). With many antioxidants, they themselves can become pro-oxidant unless they are recycled by another antioxidant. Astaxanthin, importantly, has an unlimited ability to provide chemical groups without itself becoming a pro-oxidant. Astaxanthin also works by calming free radicals, absorbing the negative energy they emit. Finally, its unique chemical structure enables it to act through the entire cell, unlike fat-soluble antioxidants that tend to provide protection to the inner wall of the cell membrane, and water-soluble antioxidants that provide protection only to the outer wall. Since astaxanthin is able to span the cell membrane, it provides antioxidant protection to the inner and the outer wall, as well as the intra-membrane space.

Of all the carotenoids, astaxanthin is nature’s most potent, with the highest known ORAC value (oxygen radical absorbance capacity) – a measure of its ability to combat oxidative stress. Astaxanthin’s ability to quench free radicals is 6,000 times greater than vitamin C, 800 times that of coenzyme Q10 and 550 times that of vitamin E.

Studies to date show astaxanthin’s ability to reduce and terminate oxidative stress, protect against unwanted inflammation and protect cell structure and function, providing health-enhancing properties in the following areas:

  • Astaxanthin for ageing skin – Skin ageing occurs over time, but the ageing process is accelerated by certain lifestyle factors and exposure to agents which cause oxidative stress in the skin – like, for example smoking, drinking alcohol, UV exposure from the sun and poor diet, amongst others. Studies illustrate that supplementation and topical application of astaxanthin improved the appearance of ‘crow’s feet’, improved elasticity, skin texture and moisture content over the course of 8 weeks (1). Who doesn’t want to keep that fresh-faced and crease-free complexion for longer?
  • Astaxanthin for exercise – Exercise leads to production of reactive oxygen nitrogen species (RONS) within muscle, which promote improvement in athletic performance. Without the body’s own antioxidant capabilities, RONS can cause a state of oxidative stress, the body can become overloaded during times of vigorous exercise, thus leading to oxidation, damaging molecules and potentially a negative impact on physiological function. Astaxanthin is not only a powerful antioxidant, but as it also upregulates the body’s own antioxidant capabilities, it helps to rebalance the oxidative stress caused by an over-production of RONS, with 3-5 weeks of astaxanthin supplementation shown to improve exercise metabolism, performance and recovery (2).
  • Astaxanthin for neuroprotection – Astaxanthin is a fat-soluble molecule, enabling it to pass the blood-brain barrier where it can exert its beneficial effects neurologically. With its ability to upregulate the body’s own antioxidant capabilities, as well as exerting anti-inflammatory effects, supplementing with astaxanthin can reduce the production of reactive oxygen species (ROS), the build-up of which can lead to tissue damage and therefore loss of function following a cerebrovascular event (3).
  • Astaxanthin for cardiovascular disease – Studies suggest that taking astaxanthin before an ischemic event provides protection to the muscle tissue of the heart (4). It has also been shown to have a positive effect on cholesterol levels by decreasing overall triglycerides and increasing HDL (‘good’) cholesterol, which provides protection against atherosclerosis as HDL cholesterol carries LDL (‘bad’) cholesterol back to the liver to prevent it from forming plaques in the arteries (5).
  • Astaxanthin for eye health – Astaxanthin protects the cells of the eye following an ischemic attack (6) and also inhibits retinal damage following white light exposure (7). A 6mg daily dose of astaxanthin for 4 weeks has also been shown to improve the function of the eye in middle-aged participants with eye strain complaints (8).
  • Astaxanthin for immunity – Astaxanthin has been shown to boost the immune response and reduce DNA damage when exposed to infection (9).
  • Introducing Pure Essentials AstaPure Astaxanthin Complex

    Pure Essentials AstaPure Astaxanthin Complex is a natural extract from the microalgae Haematococcus pluvialis (H. Pluvialis) – the same algae responsible for the pink-red pigmentation of wild salmon and crustaceans. AstaPure contains the highest available concentration of astaxanthin, as well as a complex of other beneficial carotenoids including lutein, canthaxanthin, zeaxanthin and beta-carotene, amino acids and fatty acids, which together offer a broad range of health benefits, enhance its bioavailability and increase cell membrane stability.

    7 Health Benefits of Using Pure Oxygen

    Pure oxygen has been used by hospitals to improve our health for over 200 years and has been recorded to improve our exercise performance since as early as 1928, although the first famous figure was Sir Roger Bannister, who published a research paper about the benefits of using pure oxygen in 1954 (the same year he broke the 4 minute mile).

    Whilst not new, the use of pure oxygen is becoming more widely accepted and more widely understood for the health benefits it can provide. Air contains 21% oxygen and canned oxygen is normally 95%.

    Here are 7 Health benefits of using pure oxygen:

    1. Slow down ageing skin

    From wrinkle creams to moisturising gels to facials, we all want to slow the ageing process. Getting rid of those crow’s feet, laughter lines or frowning tell tale marks, the beauty industry offers every type of product and solution that our heart’s desire. Pure oxygen is starting to break onto the scene to help us in the fight against ageing. Try canned oxygen as part of your daily beauty regime.

    2. Stressful lives

    The 9 to 5 is a challenge for all of us. Trying to get more done in the same amount of hours is best described by the ‘Carrot and Donkey’ fable. From getting to work, wanting to achieve more, dealing with more than one person should, followed by trying to fit enough house time, family time, and me time, can have us at breaking point several times per week. We all know that when we are stressed someone normally suggests ‘taking a deep breath’. Pure oxygen can help you take a moment, get pure oxygen into your bloodstream and help you tackle the road ahead with a little more ease because pure oxygen can help to reduce stress.

    3. Think faster

    A study by the Human cognitive Neuroscience Unit in Northumbria experimented with pure oxygen and concluded that those breathing pure oxygen remembered up to 20% more words, from a given list, than those that did not breathe pure oxygen. If you are struggling some days to focus, get things done, then breathing pure oxygen can help make those tasks that bit easier and quicker.

    4. That jetlag feeling

    Flying on long haul is challenging enough with not enough leg room and then arriving to feel as though all your energy has been left on the plane. The reasons for this are to do with the change in time zone, obviously the long travel, and also the increased pressure in the airplane cabin, which means that less oxygen enters your blood stream. Using pure oxygen will help you to overcome jetlag quickly and help you to enjoy your holiday sooner.

    5. Speeds up recovery

    Footballers, rugby players, and runners, to name a few, are breathing pure oxygen to help them speed up their recovery. Of course, when you earn tens of thousands per week and your team depend on you, or you just want to get back to winning again, speed of recovery is key. Breathing pure oxygen has been prescribed by hospitals for recovery and now breathing pure oxygen can help everyone that is looking to recover more quickly from injury, a minor operation or a period of being unwell.

    6. The great detoxer and cleanser

    According to many health gurus the great body cleanser and detoxifier is oxygen. Our lifestyle is less physical than our ancestors and so we are not oxygenating our blood as well as they did, which leads to our bodies carrying more toxins than we did generations before us. Breathing pure oxygen can help to reduce those toxins that we carry in our bodies, in turn helping us to be healthier.

    7. Booost the immune system

    Our immune system helps us to fight infections, diseases, coughs & colds, and helping it do its job is key to living more healthy. There are a number of ways you can maximise your immune system, like eating healthily, exercising regularly, moderating your alcohol, and breathing pure oxygen is another way of helping you to help your immune system to help you.
