What is astaxanthin

Astaxanthin – King of carotenoids

Astaxanthin is the strongest known antioxidant belonging to the carotenoid group. In nature, it is found, for instance, in algae, salmon, lobster, prawns and flamingo feathers. These organisms are coloured orange to red depending on their content of astaxanthin. Scientists claim that astaxanthin gives salmon the strength and stamina to overcome their long journeys upriver and up through waterfalls. Countless comparative studies have proven astaxanthin to be the strongest natural antioxidant ever found.

Many scientific studies have demonstrated that astaxanthin has beneficial effects not only on the muscles, cardiovascular system, eyes and brain, but also on the immune system and the skin.

Astaxanthin as an antioxidant is:

  • 500 times stronger than Vitamin E
  • 560 times stronger than the catechins in green tea
  • 800 times stronger than the coenzyme Q10
  • 3,000 times stronger than Resveratrol
  • 6,000 times stronger than Vitamin C

Astaxanthin is currently produced from seven different sources. As evident from the table (see below), the Haematococcus pluvialis algae contains the highest concentration of astaxanthin. Haematococcus pluvialis is currently the only type of algae cultivated by Algamo Ltd.

Astaxanthin content in individual natural sources:

Proven positive effects of astaxanthin

Astaxanthin is a very strong antioxidant so it is very effective in free radical neutralization. Radical is a chemically highly reactive molecule that strengthen organic redox reactions. These reactions have an adverse effect on body cells, tissues as well as whole organs and are the cause of many serious diseases. The occurrence of free radicals in human body is caused by many factors, such as air pollution, lifestyle, stress etc. Astaxanthin is a great choice in free radical neutralization and reduction.

Many reviewed articles published in renowned scientific magazines and more that forty clinical tests and trials have confirmed safety and effectiveness of astaxanthin as the strongest natural antioxidant.

Astaxanthin usage has a beneficial effect on:

  • musculoskeletal system (muscles, joints, tendons),
  • cardiovascular system,
  • immunity,
  • eye health,
  • brain health,
  • skin health.

Natural versus synthetic astaxanthin

  • Natural astaxanthin is extracted from living microalgae as compared to synthetic astaxanthin which is manufactured from petrochemicals or petrochemical derivatives.
  • Natural astaxanthin has a higher biological activity than synthetic astaxanthin.
  • Natural astaxanthin is 20 to 50 times stronger than synthetic astaxanthin.
  • Natural astaxanthin is safe for human and animal use.
  • The synthetic astaxanthin has never been tested for safety in human use.
  • Human use of the synthetic astaxanthin is not allowed.

Side effects

Studies have shown a very high safety rate of astaxanthin and a very low rate of minor side effects such as reduction of calcium levels, decreased blood pressure, increased hair growth and pigmentation of the skin. There are no dangerous side effects associated with the use of astaxanthin, not even at high doses. Possible side effects recede quickly, there is no reason for concern.

Pregnant and breastfeeding women should consult the use of astaxanthin with their doctor.
