The global astaxanthin market is estimated to reach $7.5 billion by 2031, according to a new report by Straits Research.
Astaxanthin is gaining attention as a supplement with potential benefits — some suggest it may help give the skin a natural glow, while others believe it could support cognitive and cardiovascular health. There’s ongoing research to explore if its properties might help manage COVID-19 related complications. (1)
But, like all health trends, it’s worth examining the validity of these claims before adding this supplement to your diet.

What is astaxanthin?
Astaxanthin is a type of natural pigment that belongs to a group of substances called xanthophyll carotenoids. These pigments give plants, algae, and certain animals their vibrant colors, ranging from yellow to deep red.
Astaxanthin is found in a variety of microorganisms (like certain algae and yeast) and marine animals, such as salmon, trout, krill, shrimp, and lobsters, which is why these creatures often have a reddish or pinkish hue. (2)
Astaxanthin is available as a supplement, which is typically derived from the microalgae Haematococcus pluvialis and the bacterium Paracoccus carotinifaciens. It can also be produced synthetically.
The potential benefits of astaxanthin
There are many claims about the potential benefits of astaxanthin. Although the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) haven't officially endorsed any health benefits, we’ll explore some of the more common ones below:
- Skin health. Some studies suggest that astaxanthin may help support skin health by protecting skin cells and reducing the appearance of aging signs like wrinkles. It might also help manage the effects of sun exposure. (2)
- Brain health. Astaxanthin has been shown to cross the blood-brain barrier and, as a result, may have neuroprotective qualities. Some studies have found evidence suggesting it could support cognitive and psychomotor function as people age. (3, 4)
- Immune support. Astaxanthin is recognized as a strong antioxidant with anti-inflammatory properties, which means it may help manage inflammatory responses. This could be important in managing conditions like COVID-19, which can cause a cytokine storm — an overreaction of the body's immune system. (5)
The side effects of astaxanthin
Studies find that astaxanthin is generally safe when it is consumed with food. (6) The FDA has also placed astaxanthin on the GRAS (generally recognized as safe) list.
However, it should be noted that astaxanthin is only GRAS at 6 to 7 milligrams (mg) daily and only when it’s derived either from Haematococcus pluvialis or Paracoccus carotinifaciens.
While astaxanthin is generally considered safe, some individuals may experience side effects, so it's essential to consult with a healthcare provider before starting any new supplement.
Is astaxanthin worth taking?
While astaxanthin has so far been shown to have several potential health benefits, more research is needed to fully understand its effects and optimal dosage.
It’s also important to be aware that supplements, while regulated by the U.S. Food and Drug Administration (FDA), are categorized as food, not drugs, which means they’re not held to as high of a standard. This means that quality may vary widely.
All of this to say: it’s important to do your research before adding an astaxanthin supplement to your regimen.
