Health Benefits
of Astaxanthin
Health
Benefits of Astaxanthin Revealed - Astaxanthin is a
potent antioxidant that is more than 10 times as
potent as other carotenoids. Scientific evidence is mounting that it
may hold the key to protection against heart
disease and cancer and to reverse the aging process.

Facts
on Astaxanthin
Human studies
show that it is
a potent antioxidant that protects cells against oxidative
damage caused by free radicals. Unlike other carotenoids that
convert to vitamin A, this one does not. (High doses of vitamin A are
harmful to the body.)
Chemical Structure of Astaxanthin
It is approved
by the FDA as a red
food coloring for use in
animal and fish foods and in Europe, it is considered a food dye. It is
naturally found in salmon, krill, arctic shrimp, phaffi yeast and the
microalgae Haematoccocus
pluvilis.
For comparison,
4 ounces of
wild sockeye salmon would contain 4.5 mg of
astaxanthin and Atlantic salmon would contain 0.5 to 1.1 mg.
Research
studies to support natural astaxanthin benefits
Enhances fertility in men
A well-designed
clinical study involving 30 men showed that taking 16 mg daily of
astaxanthin increased sperm motility and other measured sperm
parameters. More importantly the fertility and pregnancy rates were
significantly higher in the group taking astaxanthin.
This confirms previous animal studies that show positive benefits of
astaxanthin supplements on
reproductive health and fertility.
Age-related
macular degeneration (AMD)
Taking a
combination of astaxanthin along with vitamin C, vitamin E and
several other vitamin and minerals for 12 months improved the visual
function in those suffering from age-related macular degeneration.
Antioxidant benefits
and immune system booster
Taking
astaxanthin was shown to reduce cellular DNA damage and to boost the
immune response in young health females. This benefit was seen both at
4 weeks and 8 weeks.
Acid reflux symptoms treatment
A
well-designed clinical study showed that taking astaxanthin at dose
of 40 mg daily was effective in reducing heartburn symptoms in 4 weeks.
It was much more effective in those who were infected with the stomach
bacteria H. pylori.
Skin anti-aging cure and
protection
Lab
studies show that astaxanthin protects against the damaging effect
of UVA rays from the sun that causes the skin to age prematurely.
Researchers believe that astaxanthin could have a protective effect
against sagging and wrinkles of the skin. Further studies will be
needed to reconfirm all the reported health benefits of astaxanthin in protecting against skin damage and aging.
What's the difference between astaxanthin and
canthaxanthin?
Canthaxanthin
is another beta-carotene carotenoid like astaxanthin. It also shows
similar health benefits.

Side Effects and
Precautions
Astaxanthin
has the
Generally Recognized As Safe (GRAS) status in the United States.
There are no significant side effects or toxicity from using
astaxanthin even at a high dose of 20 mg daily. Other rare and minor
side effects include lowering of blood pressure, hormonal changes and
changes in blood counts.
When taken for long periods of time (e.g. months to years) at a high
dosage there may be discoloration of the skin.
Dosage
to Use
Typical dosage
used ranges from 2 to 12 mg (milligrams) daily.
