8 Best Astaxanthin Supplements (2022) Reviewed and Compared

Never miss a glorious update - click here!

If you, like most people, feel unsettled about the prospect of aging, you may want to add a supplement called astaxanthin (pronounced as-ta-zan-thin) to your anti-aging protocol.

This orange-red pigment is part of the carotenoid family. And there’s evidence that it may protect the health of your skin, brain, heart, and eyes.

What is Astaxanthin?

Astaxanthin is a naturally occurring carotenoid produced by the oceanic microalgae Haematococcus pluvialis in response to stress.

If you eat seafood, you can get it from salmon, shrimp, lobster, and crab. These guys get their color from the buildup of astaxanthin in their tissues.

It’s also available as a safe (and reasonably priced) supplement.

What Are the Benefits of Astaxanthin Supplements?

There are potent antioxidants on the market, but astaxanthin may beat them all.

Astaxanthin quenches free radicals like a boss. It’s known as “The King of Carotenoids.”

Research suggests it’s 800 times stronger than CoQ10, 3000 times stronger than resveratrol, and an incredible 6000 times stronger than vitamin CImpressive, right?!

This comes down to its unique lipophilic and hydrophilic structure (in English: it loves water and fat). It can become part of the cell membrane, where it strategically protects both the inside and outside of your cells.

In short, by reducing oxidative stress, astaxanthin helps cells function more efficiently, with knock-on effects for overall health.

Astaxanthin may also have the following benefits:

Encourages Healthy Skin

Astaxanthin may help you achieve smooth, healthy skin by slowing down sun damage and premature signs of aging. Sign me up!

This study found astaxanthin protected the skin from UV damage and reduced moisture loss.

Another study found a combination of oral and topical astaxanthin reduced crow’s feet and improved skin elasticity, hydration, and texture in men and women.

Promotes Heart Health

Astaxanthin quells inflammation and oxidative stress – factors we know are enemies of a healthy heart.

Astaxanthin may slow the progression of atherosclerosis (which leads to the hardening of arteries).

In addition, studies show it may reduce harmful triglycerides and low-density lipoprotein (LDL) cholesterol while increasing beneficial high-density lipoprotein (HDL) cholesterol.

Supports Brain Health and Cognitive Function

Astaxanthin crosses the brain-blood barrier, putting it in a unique position to protect you from age-related cognitive decline.

A study on people with age-related forgetfulness found that both 6 mg and 12 mg of astaxanthin improved their cognitive functioning. However, this study found astaxanthin only improved word recall in those aged 45-54.

How We Ranked

We reviewed what we believe are the best astaxanthin supplements.

To help you make the best decision for your lifestyle, here are the factors we considered when ranking the supplements.

Strict Testing Standards

The FDA does not regulate the supplement industry. It’s like the wild West out there!

We selected products subject to strict third-party testing and made according to Good Manufacturing Practice (GMP) regulations.


Did you know there is a synthetic form of astaxanthin added to farmed salmon to give it a pop of color?

Unfortunately, this is much less effective than naturally-occurring astaxanthin from algae.

We ensure all the products here contain astaxanthin from microalgae sourcesnot crustaceans or fish. This makes them safe for people with seafood allergies.

We also prioritized non-GMO, patented forms of astaxanthin sourced from microalgae grown in controlled environments.


Astaxanthin has a unique fat-soluble structure, which allows it to merge with your cell membranes. We only included products that use a lipid delivery mechanism to enhance bioavailability.


We compare the overall price of each product based on what they offer. We strive to list products that are high-quality and affordable.


Can Astaxanthin Boost Exercise Performance?

It’s safe to say astaxanthin’s anti-inflammatory properties may help you stay mobile as you age. But can it improve your performance?

A couple of studies have shown astaxanthin may increase endurance and performance during aerobic exercise. But this study on cyclists showed no impact on performance.

As of now, we can’t say for sure whether astaxanthin has any effect.

Note: If you try astaxanthin for performance, don’t take it too close to a workout. Antioxidants blunt oxidative stress and muscle fiber damage, which are necessary to trigger muscle growth and adaptation.

Does Astaxanthin Support Healthy Vision?

Theoretically, astaxanthin should protect the vasculature of the eyes and slow age-related eye problems.

This study found an antioxidant blend with 4 mg of astaxanthin reduced eye strain in older people.

However, we need more clinical studies using astaxanthin as the sole ingredient.

Can Astaxanthin Improve Arthritis?

Animal studies have found astaxanthin has anti-arthritic activity. It may protect against osteoarthritis by lowering inflammation and reducing cartilage destruction. But we need human studies to support these findings.

Does Astaxanthin Improve Male Fertility?

This small clinical study found a high dose of astaxanthin (16 mg per day) increased sperm velocity. Pregnancy rates also increased in their partners during this time.

Can Astaxanthin Improve Immunity?

Limited research suggests astaxanthin may support a healthy immune response.

This study on healthy women found taking astaxanthin over two months increased the activity of natural killer cells.

What is the Best Astaxanthin Dose?

There is no official recommended dose for astaxanthin, but human studies have found 4-16 mg daily to be the most beneficial.

Most supplements offer astaxanthin in 4, 6, 10, and 12 mg doses.

Does Astaxanthin Have Side Effects?

Astaxanthin supplements are well-tolerated by most people. Studies have used doses of up to 40 mg per day with no ill effects.

In some people, it may result in red-orange skin coloration. However, this is rare and will go away when you stop supplementing.

We encourage you to speak to your doctor to see if astaxanthin is right for you.
