Product Description
   Astaxanthin is a carotenoid. It belongs to a larger class of phytochemicals known as terpenes, which are built from five carbon precursors; isopentenyl diphosphate (or IPP) and dimethylallyl diphosphate (or DMAPP). Astaxanthin is classified as a xanthophyll (originally derived from a word meaning "yellow leaves" since yellow plant leaf pigments were the first recognized of the xanthophyll family of carotenoids), but currently employed to describe carotenoid compounds that have oxygen-containing moities, hydroxyl (OH) or ketone (=0), such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin and/or canthaxanthin, containing both hydroxyl and ketone functional groups. Like many carotenoids, astaxanthin is a colorful, lipid-soluble pigment. This 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 found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. It provides the red color of salmon meat and the red color of cooked shellfish. Professor Basil Weedon's group was the first to prove the structure of astaxanthin by synthesis, in 1975

   Astaxanthin, unlike several carotenes and one other known carotenoid, is not converted to vitamin A (retinol) in the human body. Like other carotenoids, astaxanthin has self-limited absorption orally and such low toxicity by mouth that no toxic syndrome is known. It is an antioxidant with a slightly lower antioxidant activity in some model systems than other carotenoids. However, in living organisms the free-radical terminating effectiveness of each carotenoid is heavily modified by its lipid solubility, and thus varies with the type of system being protected.

   While astaxanthin is a natural nutritional component, it can also be used as a food supplement. The supplement is intended for human, animal, and aquaculture consumption. The commercial production of astaxanthin comes from both natural and synthetic sources.




Benefits & Uses
1. Astaxanthin is a reddish pigment that belongs to a group of chemicals called carotenoids. It occurs naturally in certain algae and causes the pink or red color in salmon, trout, lobster, shrimp, and other seafood.

2. Astaxanthin is used for treating Alzheimer's disease, Parkinson's disease, “brain attack” (stroke), high cholesterol, and an eye condition called age-related macular degeneration (AMD). It is also used for preventing cancer.

3. Astaxanthin is applied directly to the skin for protection against sunburn.

Astaxanthin is an antioxidant. This effect might protect cells from damage.

5. Astaxanthin might also improve the way the immune system functions.

What's a standardised plant extract?
In contrast with ordinary plant powders, standardised plant extracts contain specific quantities of active ingredients. In order to manufacture a supplement based on plants, it is not sufficient to simply grind down just any part of the plant.

How are standardised plant extracts obtained?
The quantities of active ingredients in plants can vary considerably, as a result of the variety of plant used, the part of the plant used (the highest concentrations of active ingredients are usually to be found in a specific part of the plant: root, leaf, stem, flower, fruit) and the environment (climate, season, soil) in which the plant is grown. That’s why the plants are first accurately identified and monitored before they are harvested. During the extraction of the plants, the active ingredients are dissolved. Thereafter, the solvent used (water or alcohol) is evaporated. As a final step, the concentrated extract is analytically controlled and the active ingredients are standardised.

Standardised plant extracts have several important advantages in comparison with ordinary plant powders:
* They guarantee the constant quality of the end product.

* They have a higher concentration of active ingredients as a result of the removal of the ballast substances.

* They can be kept for longer periods the ballast substances can’t ‘contaminate’ the active ingredients any more.

* They have a higher level of bio-availability: they are more easily absorbed by the body.
