Astaxanthin is one such carotenoid, that occurs naturally in organisms like salmon, crabs, shrimp, chicken, and egg, as well as trout, yeast, and microalgae, to name a few. It occurs naturally in certain algae as well.
So, the pinkish red tinge of colour that these organisms possess, comes from the presence of this carotenoid. .

6. Astaxanthin uses in male infertility
Infertility can be frustrating.
While there are several causal factors of infertility like obesity, hormonal issues, testicular trauma, and genetic issues, there is another cause as well – oxidative stress.
A strong link has been found with sperm oxidative stress and infertility.
Astaxanthin’s antioxidant properties can help deal with this. A study in 2005 says that astaxanthin can help with male fertility as well .
According to the study, the research that was conducted on a group of men, saw positive results, which included better quality of sperm like motility and count, and overall improvement of fertility.
Yet another study claimed that it can help with sperm capacitation as well 
However, since this particular research was conducted on a small group of people, it is insufficient evidence. More research will be necessary to support this claim.
7. Great for your heart
It is believed that astaxanthin can help lower cholesterol and prevent heart diseases.
In a recent study, research was conducted on rats, and the results were promising.
Astaxanthin showed to have a positive impact on hypertension, as well as an improvement on the thickness of the arterial wall and elastin levels .

An imbalance between peroxynitrite and nitric oxide is one of the leading causes of problems in the blood vessels, the lining of the arteries, and the endothelium.
It has shown to restore any impalace between peroxynitrite and nitric oxide, which is beneficial for the heart. 
8. Relieves symptoms of menopause
Menopause is the natural decline of the menstrual cycle in a woman.
This period can be particularly stressful for most women.
Women who are menopausal, will experience various symptoms like anxiety, hot flushes, stress, and sometimes even depression. 
Hot flushes are triggered by stress hormones like cortisol and oxidative stress.
As mentioned above, it can help reverse the effects of oxidative stress. The intake of astaxanthin has shown signs of reduction of menopausal symptoms as well. 
9. Regulation of cholesterol
Most people have a misconception that cholesterol is bad. However, the fact is that the liver produces cholesterol naturally. Cholesterol is used for making hormones.
But, the problems starts when there is an abnormal increase in the cholesterol levels, which settles along the blood vessels, causing a blockage. This is the perfect recipe for heart attacks and other heart related ailments, as well as strokes.
Now, this is where astaxanthin comes into the picture. A regular intake of 6 to 18 mg, for around 84 days, has shown to reduce the level of cholesterol in the blood. 
10. Can help manage diabetes
There has been a steady rise in the number of people suffering from diabetes, thanks to the choice of lifestyle we have been living.
In case you didn’t know, diabetes is caused due to a malfunction of the pancreas and the irregular production of insulin.
And this in turn stems down to damage of the beta cells in the pancreas. This takes place due to inflammation or oxidative stress. 
It can help with oxidative stress, thanks to its antioxidant properties.
It can also help with sugar toxicity in the blood.
11. Great for your immune system
The immune system is your body’s defence force. When the immune system is weak, so are you.
A good immune system protects the body from invaders like germs, bacteria, virus, and disease.

It has shown to reduce inflammation and, of course, oxidative stress in the body, thereby helping you keep your immune system at optimal health.

We’ve discussed the benefits of astaxanthin, but are there any side effects?
The Food and Drug Administration (FDA) considers Astaxanthin to be safe in moderation .
However, too much of anything is bad, so make sure you do not over indulge in it.

High doses of astaxanthin can cause sudden stomach pain as well.
As far as consumption during pregnancy is concerned, there is not enough knowledge.
It is best to steer clear of any complications during this crucial period, so avoid the use of astaxanthin during this time.
The same can be said about mothers who are breast-feeding as well. 
Various factors like your age and state of health come into consideration while administering the right dosage.
In general, doctors say that 4 to 40 mg on a daily basis for 12 weeks or around 12 mg on a daily basis for 6 months, has been considered safe, with no side effects.
