Astaxanthin Uses, Benefits, Side Effects, Dosage, and Warning
Astaxanthin is a pinkish-red carotenoid pigment found in microalgae, yeast, shrimp, trout and other sea animals. The salmon and the flamingo both get their color from this pigment as they eat foods high in this carotenoid.
These animals don’t turn brilliant pink on their own. They eat shrimp and blue-green algae that gives them their pink color.
Humans also transform carotenoids, like beta-carotene, into vitamin A, which is why every nutrition unit stresses that we should eat “a rainbow of foods,” from orange carrots and sweet potatoes to red peppers and green broccoli. We need them to stay alive. (20)
Healthcare professionals and fitness enthusiasts are using it as a dietary supplement, and it has been dubbed the ‘King of Carotenoids’. But what exactly is astaxanthin, and more importantly, should you be consuming it?

What is astaxanthin?
Astaxanthin is what is known as a carotenoid. Carotenoids are pigments that are found naturally in various organisms. It 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 .
The muscle of salmon happens to have the highest concentration of astaxanthin in the animal kingdom. It is an antioxidant as well. But that’s not all, a recent study showed that it has antifungal and anti-inflammatory properties too .
Astaxanthin is obtained from which source
Astaxanthin is produced from H. pluvialis is a main source for human consumption. (6)
Haematococcus pluvialis (Chlorophyta) is a freshwater, unicellular algae with a rather complex life cycle. Its ovoid vegetative cells are motile by way of two flagella and during growth, nonmotile cells (cysts) also occur. (7)
For dietary supplement in humans and animals, astaxanthin is obtained from seafood or extracted from H. pluvialis.
Astaxanthin Uses and benefits
So we now know that astaxanthin is a carotenoid, but what exactly are its uses and benefits? Read on
1. Works as a great antioxidant
An antioxidant can protect your body from the negative effects of free radicals, which are harmful to you. Antioxidants can accept or donate electrons, without getting destroyed, thereby balancing the effects of the free radicals.
Additionally, antioxidants also protect the body from cell damage. It works as a great antioxidant. In fact, among all the carotenoids, astaxanthin happens to have the highest antioxidant properties.
As an antioxidant, it helps lower oxidative stress that is caused due to being overweight and smoking of tobacco as well .
Oxidative stress takes place when there is an imbalance between the free radicals and antioxidants in the body, which will increase the risk of free radicals. When there is an increase in free radicals, you are bound to experience inflammation.
A good intake of antioxidants like astaxanthin can help reverse this issue by neutralizing the effect of free radicals. 
2. Helps in reducing pain and inflammation
It can help relieve pain, especially pain and inflammation related to arthritis. It also helps with joint pain, rheumatoid arthritis, and carpal tunnel syndrome. Both rheumatoid arthritis as well as carpal tunnel syndrome, are the leading causal factors of joint pain.
However, there is insufficient evidence to back the effects of astaxanthin on carpal tunnel syndrome. Additionally, it has shown positive results in preventing inflammation caused by the H. pylori bacteria as well. 
3. Treatment of cancer
Antioxidants can play a significant role in the treatment of cancer, as it helps protect damaged cells. The high antioxidant properties of astaxanthin are beneficial for the protection from cancer-causing cells.
One study concluded that it has both long term and short term benefits in the treatment of breast cancer, where it leads to the death of breast cancer cells. 
4. Great for your eyes
Antioxidants can help protect the retina of the eye from oxidative damage. It has superior antioxidant activity, that is great for your retina, as well as age-related macular degeneration, diabetic retinopathy, and eye strain and fatigue.
Since it is found mainly in fish, the consumption of it includes omega-3 fatty acids, which again, is great for your eyes. 
5. Works wonders for your skin

It does not really have SPF, but still, it has great UV-blocking properties as well, which protects your skin from damage related to sun exposure. 
6. Increases male fertility
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.
Sperm oxidative stress and infertility can be strongly linked. Astaxanthin’s antioxidant properties can help deal with this. A study in 2005 says that It 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 it 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 [11). So that makes astaxanthin a potential anti-hypertention drug as well!
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. 
Stress hormones like cortisol and oxidative stress trigger hot flushes. 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 naturally produces cholesterol. This, in turn, is sent out to the blood, and then used for the cell and for making hormones.
But, the problems start 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, here is where It 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, malfunction of the pancreas and the irregular production of insulin causes diabetes. 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. Astaxanthin has shown the ability to manage diabetes as it can help with the improvement of metabolism of sugar and lower high blood pressure as well. 
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. However, prolonged inflammation and oxidative stress can negatively impact the immune system. 
It has shown to reduce inflammation and, of course, oxidative stress in the body, thereby helping you keep your immune system at optimal health. 
12. Astaxanthin benefits for weight loss
13. Astaxanthin uses in female fertility
Researchers conducted a study on a group of women with endometriosis. Endometriosis is a condition that is linked to female fertility. Both endometriosis and infertility are linked to low levels of antioxidants and an increase in oxidative stress and free radicals in the body. It has superior antioxidant qualities, which can help reverse this and aid with female fertility.
Best time of day to take Astaxanthin
Astaxanthin is fat-soluble and best taken along with a fatty meal. It can be taken once a day with a fatty meal to increase its absorption.
If you’re an athlete, or work out regularly, please be aware that several studies have shown that taking antioxidant supplements before exercise may lead to decreasing insulin sensitivity. It also hampers your body’s ability to defend itself against oxidative damage. (8)
