Astaxanthin obstructs the oxidation of lowdensity<br />
lipoprotein (LDL) and raises the level<br />
of high-density lipoprotein (HDL) cholesterol<br />
and adiponectin, a fat tissue hormone that<br />
is, together with other hormones, responsible<br />
for the regulation of the energy metabolism.<br />
Adiponectin originates from fat tissue<br />
and influences insulin activity in the glucose<br />
and fat metabolism. Extensive studies have<br />
demonstrated that astaxanthin can act preemptively<br />
against arteriosclerotic cardiovascular<br />
diseases as it may alleviate oxidative<br />
stress and resultant inflammations as well as<br />
lipid and glucose metabolism.[6],[7]<br />
Cardioprotective effects of natural astaxanthin<br />
have, for instance, been ascertained<br />
in a clinical, randomised, placebocontrolled<br />
double-blind study. In the study,<br />
44 probands with type 2 diabetes were daily<br />
supplemented with 8 mg of asta xanthin<br />
over 8 weeks. The intake of astaxanthin led<br />
to a significant increase of the adiponectin<br />
concentration in the serum (p < 0.05) and<br />
to a reduction of the visceral body fat mass. Moreover, a significant<br />
astaxanthin-induced reduction of triglyceride and LDL cholesterol in<br />
the blood and a lowering of the systolic blood pressure were demonstrated.[7]<br />
These results affirmed findings from previous studies and<br />
illustrated the high potential of natural astaxanthin to pre-emptively<br />
counteract arteriosclerotic cardiovascular diseases. Cognitive health<br />
also plays a major role in maintaining all important body functions.<br />
In some ways, our brain is the control centre of the body. Due to<br />
several blood vessels, it has high oxygen consumption and is susceptible<br />
to oxidative stress. Especially with advancing age, natural antioxidative<br />
enzymes in the body become less effective, through which<br />
inflammations and, consequently, neurodegenerative diseases may<br />
occur. Astaxanthin is one of the less known compounds that can overcome<br />
all the blood-brain barrier by which its antioxidative properties<br />
are also enhanced in the human brain.[8],[9]<br />
A randomised placebo-controlled double-blind study with 89 participants<br />
has shown that a 3-months nutritional supplement with a daily<br />
dose of 12 mg of natural astaxanthin influences the cognitive performance<br />
of older probands. In this clinical study, various parameters to<br />
determine the cognitive performance like working memory, delayed<br />
memory to measure accuracy or short-term working memory were<br />
significantly enhanced in participants supplemented with astaxan-<br />
