Questions to Consider Before Buying Astaxanthin supplements

What is astaxanthin?

Astaxanthin is an antioxidant and natural color that belongs to the group of carotenoids. It is mainly produced by freshwater algae and is reddish-purple in color.
This is why, for example, the red color of crustaceans or salmon, as they eat the algae.

The dye is obtained industrially from the so-called “blood rain algae” or Haematococcus pluvialis. Algae production takes place mainly in Hawaii and partly in Israel.

What are Antioxidants and Free Radicals?

Free radicals are constantly forming in our body and in all living organisms in a natural process.
These are aggressive molecules or reactive compounds that e.g. Can be found in polluted air, UV light and rancid fat.

Free radicals damage proteins, fats and the DNA of cells through oxidation. This accelerates the aging of our bodies and diseases like cancer, diabetes and heart disease can develop.

Antioxidants ensure that free radicals are inhibited so that they cannot damage the body’s cells.

So-called antioxidants counteract this process. They defuse the free radicals and ensure that the body cells are not damaged by them.

Antioxidants are chemical compounds that slow down or prevent oxidation. In addition to astaxanthin, examples of antioxidants include Beta Carotene, Vitamin C, Vitamin E and Resveratrol.

Why should I use astaxanthin?

Thanks to the antioxidant effect described above, astaxanthin keeps you young and fit, protects the heart and curbs many diseases such as diabetes and asthma.
It also strengthens eyesight and the immune system, has anti-inflammatory effects, helps with infertility, ensures more extensive regeneration of the brain in the event of strokes and acts from within as a natural sun protection against UV radiation.

According to researchers, astaxanthin is said to …

  • 6000 times stronger than vitamin C.
  • 800 times stronger than CoQ10
  • 550 times stronger than green tea catechins
  • 550 times stronger than vitamin E (alpha tocopherol)
  • 75 times stronger than alpha lipoic acid
  • 40 times stronger than beta carotene
  • 17 times stronger than OPC grape seed extract

… and thus be the strongest “radical catcher”. It should be noted, however, that many of the older studies have so far been carried out with animals and the effects on humans can, but need not be identical.

How does astaxanthin help me with my exercise?

In a 2008 study, 40 students were trained in fitness, strength / endurance, and strength / explosiveness through standard exercises (such as squats) for six months.
Half of the students took only 4 mg astaxanthin a day during this time, the other half a placebo.

According to the researchers, athletic performance did not improve significantly differently in the areas of fitness and strength / explosiveness in the two groups.

However, the improvement in strength / endurance with astaxanthin was 55%.

The group that took astaxanthin for six months improved its performance three-fold compared to the group that took the placebo.

Various other studies have shown that astaxanthin reduces the production of lactic acid in muscles and thus muscle fatigue, improves eyesight, speeds up post-exercise recovery, and improves fat metabolism.

Astaxanthin is therefore a popular dietary supplement in fitness / bodybuilding, triathlon and in general in competitive sports.

In addition, there is additional protection from inside against UV radiation at outdoor sports events such as the Ironman or a marathon.

How do I dose astaxanthin and how long does it work?

In general, an intake of 4-8 mg per day is recommended. A maximum dose that the body can absorb daily has not yet been determined.

Therefore, a dosage of 12 mg or more per day can also be taken.

Astaxanthin is built up in the body, so you should take it regularly or daily for at least 2 months to achieve your desired effects.

With certain diseases or if you want to inhibit inflammation, you can also use a higher dose of e.g. Start 12 mg and then reduce it again after a certain time.

How do I take astaxanthin?

Since astaxanthin comes from the group of fat-soluble caratinoids, it is advisable to take the astaxanthin with a meal and to stimulate the metabolism.

However, most products are available in capsule form. Here the astaxanthin is already sealed together with an oil in a soft capsule.

This means that you can take these preparations completely independently of your meals.

Negative interactions with other food supplements or foods have not yet been found in any study.

Therefore, you can safely take astaxanthin together with other medicines.

However, some preparations contain active ingredients from crustaceans instead of just algae, so allergy sufferers should pay close attention to the composition.

Is there a vegetarian or vegan variant of astaxanthin?

Astaxanthin is naturally found in algae, carrots, red peppers and other vegetables and fruits with a red color.
The dietary supplements are also mostly vegan, as astaxanthin is obtained from the algae.

Most astaxanthin food supplements are vegan because the substance is obtained from freshwater algae.

As mentioned above, there are also preparations in which the substance is obtained from crustaceans. In addition, the products are usually offered as capsules.

Here, many of the capsule shells are made from beef gelatin. But there are also manufacturers who offer 100% vegetarian capsules. These are made from vegetable cellulose and coated with beeswax.

Therefore, you should definitely pay attention to the exact composition of such dietary supplements.

Astaxanthin Alternatives


The antioxidant OPC (oligomeric proanthocyanidins) belongs to the group of polyphenols and is found in grape seeds and in the skin of red grapes.

It’s also found in peanuts, cranberries, and blueberries. OPC also binds free radicals and is said to protect against cardiovascular diseases, diabetes, cancer and skin aging.

As with astaxanthin, no maximum dosage recommendation can be made. There are no studies that clearly prove that the above Prevents diseases or diabetes and improves blood vessels.


Beta-carotene is also a carotenoid and natural coloring agent. It is said to have a weaker effect than astaxanthin, but has the same anti-oxidative properties.

The ceratonoid beta-carotene also provides additional internal protection against UV radiation.

However, caution is advised! In the meantime, the additional intake of beta-carotene is no longer recommended, as many foods naturally contain the coloring agent or many foods are enriched with it.


A daily amount of 15 mg is considered safe according to consumer protection. Natural beta-carotene e.g. from carrots is not a problem and is not included in the daily dose.

Did you know that beta-carotene as a dietary supplement is said to be harmful and increase the risk of lung cancer, especially for smokers? Further research, for example on risk groups such as asthmatics, is still pending.

What types of Astaxanthin supplements are there and which one is right for you?

If you want to buy astaxanthin, you can choose between the following two types. To help you with your decision, we will introduce you to both types and weigh the advantages and disadvantages of each.

Natural astaxanthin: Advantages & Disadvantages

Natural astaxanthin is obtained either directly from the blood algae or from e.g. Crustaceans or salmon that feed on these algae are obtained.

The natural astaxanthin has the highest antioxidant potential and therefore works better because the alga also naturally supplies other antioxidants / nutrients.

Food supplements for us humans usually contain the natural astaxanthin.

Synthetic astaxanthin: Advantages & Disadvantages

Synthetic astaxanthin is produced either from a genetically modified yeast fungus (Phaffia rhodozyma) or from petroleum in a complex process.

The synthetic astaxanthin is most produced and sold in the world today, but in the form of fish feed and not for humans.

If we buy a salmon for consumption, it usually doesn’t get its color from the natural diet of freshwater algae. These animals are mostly fed the synthetic astaxanthin.

If it says on the packaging that it was fed with microalgae and thus high quality astaxanthin, in most cases it is astaxanthin from genetically modified yeast. This is significantly cheaper.

Purchase criteria: Use these factors to compare Astaxanthin supplements

In the following we would like to show you which factors you can use to compare and evaluate astaxanthin preparations. This will make it easier for you to decide whether a particular astaxanthin supplement is right for you or not.

In summary, these are:

  • Dosage
  • Composition & Quality


As mentioned above, a dosage of 4-8 mg is recommended. You can also buy astaxanthin in high doses of 12 mg.

Depending on the effect you want to achieve or whether you have a painful inflammation, you can use a product with 12 mg and then reduce the dose after a while.

If you are not a competitive athlete, you can take 4 mg per day, like the above. Study has already shown a very good effect.

Composition & Quality

Another important criterion for you can be the composition of the astaxanthin.

If you are a vegetarian or vegan, you have to make sure that the astaxanthin in the respective product is only obtained from algae and not from crustaceans.

It also makes sense to concentrate on products with natural astaxanthin instead of using synthetic preparations.

Furthermore, the astaxanthin should not contain any additives, lactose, gluten or anything else.

Facts about Astaxanthin

What is Oxidative Stress?

Oxidative stress means an increased attack of harmful free radicals. This means that the necessary balance between oxidative substances (free radicals) and antioxidative substances is no longer given in the body.

An imbalance arises, which means that the free radicals are no longer slowed down and our body cells can increasingly attack.

This can lead to faster skin aging and various diseases can be promoted.

To counteract this imbalance, you should eat a balanced and healthy diet and, in addition to supporting the antioxidants in foods, you can take a dietary supplement such as astaxanthin.
