Health Benefits and Side Effects of Astaxanthin Supplements
Astaxanthin is an
antioxidant. This effect might protect cells from damage. Astaxanthin might
also improve the way the immune system functions. 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.
It is also used for preventing cancer.
Astaxanthin has been
claimed to be ten times more effective than beta carotene and 100 times more
effective than vitamin E in preventing lipid peroxidation. Astaxanthin protects
the cellular and mitochondrial membranes and the ocular tissues against the
photo-oxidative damage to DNA, involved in AMD pathogenesis. Carotenoids can
help protect the retina from oxidative damage. The free radical scavenging
activity of astaxanthin protects lipids from peroxidation and reduces oxidative
damage of LDL-cholesterol (thereby reducing arterial plaque formation), cells,
cell membranes, mitochondrial membranes. Astaxanthin increases strength and
endurance.
Astaxanthin is one of those
important carotenoids and might be beneficial for nerve damage associated with
age-related macular degeneration. Astaxanthin may easily cross the blood brain
barrier and could have antioxidant effects in the brain. Astaxanthin might
exert beneficial effects in protection against hypertension and stroke, and
could improve memory in vascular dementia. Astaxanthin has a peculiar chemical
structure. Astaxanthin enhances the cellular membranes stability as it locates
crosswise inside them.
Astaxanthin supplements are
nutrients that help protect the body from harmful toxins which could cause
cancer and other harmful diseases. It’s said to be very similar to
beta-carotene because it has a bright red pigmentation. As a matter of fact,
it’s used as food coloring for animal food in the USA. Its potency as an
anti-oxidant is ten times stronger than beta-carotene.
Compared to beta-carotene and other Vitamin A
variants, astaxanthin supplements have lower toxicity levels. Most people take
astaxanthin supplements because they don’t have enough seafood in their diet,
which is the most common source of this nutrient. Studies have shown, though,
that those who eat seafood and still take astaxanthin supplements still benefit
from the extra dosage.
While astaxanthin
supplements include several health benefits, side effects can occur as well. You
should consult with your doctor before taking astaxanthin supplements. Astaxanthin
may hinder an enzyme called 5-alpha-reductase. As a result, it may keep
testosterone from changing into the hormone DHT in the body. Side effects can
include lower libido, growth in male breasts, and erectile dysfunction. They may also lower blood pressure and
calcium levels.
Astaxanthin supplements should be avoided if you are allergic or sensitive to:
- Similar carotenoids such as canthaxanthin
- A source of astaxanthin, such as the algae that produces it
- Drugs that inhibit 5-alpha-reductase like finasteride (Propecia, Proscar) or dutasteride (Avodart, Jalyn)
- Women who are pregnant or might become pregnant should avoid astaxanthin.
- Astaxanthin may increase your immune function, so use caution when taking it if you:
- Have autoimmune problems or you're
- Taking drugs to suppress your immune system, since it may increase your immune function
While the general feedback
from those who took astaxanthin supplements is positive, your medical records
will always be unique from everyone else’s. Your doctor’s advice is especially
necessary when you’re taking other medicines. For all you know, these medicines
might be counteracting the supplement. You wouldn’t want to waste money, or
worse, suffer from the repercussions of a bad chemical interaction by taking
astaxanthin supplements.
