Astaxanthin is a naturally-occurring carotenoid closely related to beta-carotene and lutein that provides a wide range of antioxidant benefits.

Product Notes:

Astaxanthin may play a key role in the protection of cell membranes against free radical damage as well as supporting the immune system and cardiovascular health, particularly since it can help reduce inflammation. Conditions where that can be beneficial include asthma, aching or swollen joints (whether from arthritis or from repetitive stress injury, e.g.), fibromyalgia, and even inflammatory eye (such as uveitis) or brain conditions. Safflower or olive oil have been added because astaxanthin is fat-soluble, and this improves its absorption.

Astaxanthin is a carotenoid – basically, a natural pigment or dye. It is found primarily in marine organisms such as salmon, trout, krill, shrimp, crayfish, and crustaceans – it's actually the pigment that gives salmon and crustaceans their pink/red colour – and is also found in extremely high concentrations in a type of green microalgae called Haematococcus pluvialis, which this type is made from, which may be both its richest and most sustainable source.

But astaxanthin doesn't just provide those marine organisms with their colour: it protects them from the harmful UV effects of sunlight. It's also turned out to be a very powerful antioxidant when consumed – possibly the most powerful one identified, to date – and because it is fat soluble, it's able to enter the fat layer of any given cell's outer membranes, and go on to diffuse and disarm multiple types of free radicals which may be causing oxidative damage within them.

In addition to supporting eye health, increased energy levels, and recovery from exercise, astaxanthin shows promise in being able to help the skin, and reduce inflammation, and may be able to help stave off quite a number of diseases, including cardiovascular, gastrointestinal, liver, and neurodegenerative conditions.
