Can Astaxanthin Help You Sleep?

Struggling with restless nights? You may have heard about astaxanthin—a potent antioxidant—and wondered if it could help improve sleep. While astaxanthin has been studied for various health benefits, its role in sleep quality is still being explored. Below, we’ll look at what the existing research says about astaxanthin and its possible impact on sleep, including the findings of one notable study.

What is astaxanthin and its sleep benefits?

So, what exactly is astaxanthin? This naturally occurring carotenoid is found in certain algae and seafood like salmon and shrimp.

Thanks to its antioxidant properties, astaxanthin has attracted research interest for its potential to benefit skin health, athletic performance, eye function, and more. However, clinical studies on its effect specifically on sleep are sparse.

Astaxanthin research on sleep

Although anecdotal reports suggest that some people feel more rested after supplementing with astaxanthin, rigorous data on its direct effects on sleep quality remain limited.

A single randomized, double-blind, placebo-controlled trial investigated whether an astaxanthin-rich supplement (12 mg/day from Paracoccus carotinifaciens, taken for 8 weeks) could help reduce stress and improve sleep in adults aged 20–64.

Here’s what the researchers found:

• Overall results: When looking at the entire study population, there was no statistically significant improvement in stress or sleep quality compared to a placebo.
• Subgroup analysis: However, a subset of participants with a higher tendency toward depression (based on a specific questionnaire) experienced significant improvement in sleep—especially in measures of sleepiness on rising—compared to those given a placebo.
• Safety: The astaxanthin supplement was not linked to any serious adverse effects.

These findings suggest that astaxanthin may help individuals with more pronounced depressive symptoms improve certain aspects of their sleep. Still, it’s crucial to note that more extensive research is needed to confirm these results, establish ideal dosages, and determine who may benefit most.

Dosage matters

Thinking about giving astaxanthin a try? Then you should make sure that you are taking an adequate dosage:

• Dosage in the study: Participants took 12 mg of astaxanthin per day for eight weeks.
• Other dosages: Previous research on astaxanthin for other health outcomes has examined daily dosages in the range of 4–12 mg.
• Individual factors: Factors such as diet, overall health, and lifestyle may influence how astaxanthin affects you. Always consult a healthcare professional to determine whether supplementation is right for you.

Additional benefits of astaxanthin

Astaxanthin may offer other health perks that may indirectly boost your sleep quality.

Easing eye strain

In our digital age, many of us suffer from computer vision syndrome, leading to eye strain and disrupted sleep. Astaxanthin has been shown to reduce eye fatigue and improve visual acuity.

Boosting antioxidant capacity

By increasing antioxidant enzymes like superoxide dismutase (SOD), astaxanthin helps combat oxidative stress. This not only supports better sleep but also enhances overall health. If you're curious about how antioxidants benefit your body, you might enjoy reading more about what are antioxidants.
