Like many carotenoids, astaxanthin is a lipid -soluble pigment. Its red-orange colour is due to the extended chain of conjugated alternating double and single double bonds at the centre of the compound. This chain of conjugated double bonds is also responsible for the antioxidant function of astaxanthin as well as other carotenoids as it results in a region of decentralized electrons that can be donated to reduce a reactive oxidizing molecule. Astaxanthin is a blood-red pigment and is produced naturally in the freshwater microalgae Haematococcus pluvialis and the yeast fungus Xanthophyllomyces dendrorhous also known as Phaffia. When the algae is stressed by lack of nutrients, increased salinity, or excessive sunshine, it creates astaxanthin. Animals who feed on the algae, such as salmon, red trout, red sea bream, flamingos, and crustaceans i.

Published on Mar 2, Astaxanthin, the naturally occurring carotenoid responsible for the pink-red pigmentation of wild salmon and crustaceans such as shrimp and lobsters, is a potent and effective antioxidant that boasts an ability to combat oxidative stress x greater than that of vitamin C, x coenzyme Q10, x vitamin E and 75x alpha lipoic acid.

Naturally, we are very excited to introduce AstaPure astaxanthin to our Pure Essentials range, launching in March! New research is coming out daily suggesting astaxanthin is a highly effective tool in combating age-related diseases and cardiovascular disease, as well as boosting the immune system, liver and brain function.

Astaxanthin decreased oxidative stress and inflammation and enhanced immune response in humans. Nutr Metab Lond. It is estimated that the synthetic form would need to be provided in doses 20—50 times greater than the natural form to achieve the same benefits Capelli, B.

Synthetic astaxanthin is significantly inferior to algal-based astaxanthin as an antioxidant and may not be suitable as a human nutraceutical supplement Nutrafoods 12 Esterification In nature, astaxanthin it is found either conjugated with proteins e.

Pharmacokinetics Pharmacokinetic studies are limited; however, in an open labeled study, three middle- aged male volunteers years ingested a single meal containing first a mg dose of astaxanthin followed by a dose of mg after 4 weeks Coral-Hinostroza GN, Ytrestoyl T, Ruyter B, Bjerkeng B.

The plasma astaxanthin concentration-time curves were measured over 76 hours. Maximum levels of astaxanthin Cmax for the low dose was 0. Biosci Biotechnol Biochem. Furthermore, in a separate study, taking astaxanthin after food rather than before food improved the bioavailability of astaxanthin supplements by 2-fold An open-label clinical study of the toxicity and efficacy of an astaxanthin-rich H. Preliminary clinical evaluation of toxicity and efficacy of a new astaxanthin- rich Haematococcus pluvialis extract.

J Clin Biochem Nutr. The protective effects of astaxanthin are associated with its anti-oxidative, anti-inflammatory, anti-apoptotic effects.

Astaxanthin is a safe nutrient, with no toxic effects when it is consumed with food. Furthermore, as a fat-soluble compound, astaxanthin is able to effectively pass through the BBB.

Therefore, astaxanthin is an excellent candidate for treating neurological diseases. There have been no safety concerns noted so far in human clinical studies where astaxanthin has been administered. As astaxanthin is a potent antioxidant and is associated with membrane preservation, it may protect against oxidative stress and inflammation and provide cardiovascular benefits.

Astaxanthin in cardiovascular health and disease. Astaxanthin was administered to subjects at a daily dose of 6 mg for 4 weeks, and the pupillary constriction ratio before and after astaxanthin supplementation was measured by TriIRIS C The change in subjective symptoms after supplementation was examined by a questionnaire. Dosing guidance This product should not be used as a substitute for a balanced diet. Pregnant or breastfeeding women should consult their doctor before taking any food supplement.

Keep out of the reach of children and away from sunlight. For intensive support, the dose can be increased to 4 capsules daily. For optimal absorption, astaxanthin should be taken with fats and immediately after meals. Do not exceed the above doses unless advised by a healthcare practitioner.
