About Astaxanthin
The radical defense behind the cell
Natural
Astaxanthin from the microalgae, haematococcus pluvialis, is a
natural carotenoid found in abundance
from arctic marine environments to common fresh water rock pools throughout
the world. Astaxanthin is what gives the pink and red color to
salmon, shrimp and
lobster. However, animals depend on their diet to obtain astaxanthin and
other carotenoids since they cannot produce carotenoids themselves.
The most abundant
source of astaxanthin in nature is haematococcus pluvialis, which will accumulate
astaxanthin in lipid vesicles during periods of nutrient deficiency and environmental
stresses. Because haematococcus often grows in places that are exposed to
intense sunlight during its dormant phase astaxanthin functions
to protect the cell nucleus
against free radicals generated by UV radiation that would otherwise cause
damage to its DNA and peroxidise energy reservoirs.
Fuji Chemical
Industry Co. Ltd. produces the highest purity astaxanthin in the
world from haematococcus pluvialis through its two subsidiaries,
BioReal,
Inc.
(USA) and AstaReal AB (Sweden).
BioReal, Inc.
Located on the paradise island of Maui, BioReal utilizes the proprietary,
state of the art technology we call the "BioDome" to cultivate and grow
the naturally occurring microalgae, haematococcus pluvialis for the natural
production
of astaxanthin.
The BioDome advantage
- contamination control
- purity improvement
- environmentally friendly
- astaxanthin yield improvement
BioReal (Sweden) AB
Located in Sweden, BioReal (Sweden) AB was the first
company in the world to commercialize a supplement containing natural
astaxanthin
from Haematococcus pluvialis, which was launched in the year
1995. Also to date, BioReal has completed more clinical studies
with natural astaxanthin than any other company providing an
in-depth understanding of the benefits of astaxanthin as well
a strong sense of safety surrounding the use of it.
BioReal utilizes a fully enclosed proprietary
photobioreactor system to grow, harvest and dry the microalgae
haematococcus pluvialis
under carefully controlled hygienic conditions.
Antioxidant -
Cell Membrane protection
Astaxanthin has been found to be a very potent lipid soluble
antioxidant through in vitro and ex vivo studies. It has been
shown to be 1000
times and 550 times more effective than vitamin E ( -tocopherol)
concerning lipid peroxidation and singlet oxygen quenching
respectively. Astaxanthin is also superior to many other antioxidants
because
of the unique role it may play in protecting the cell membrane
because of its unique chemical structure and orientation within
the living cell. Figure
1 shows astaxanthin's unique ability to span through the double
layer cell membrane. For example,
-carotene
resides inside the bilipid membrane and vitamin C resides outside
the bilipid membrane only. Whereas, the astaxanthin molecule
is exposed both in and outside of the cell giving overall better
protection.
In addition, it can also function as a bridge by transporting
trapped free radicals to the aqueous (polar) regions of the
cell, thus
making them available to water soluble antioxidants.
