Astaxanthin belongs to a class of phytonutrients called carotenoids primarily found in marine organisms such as algae, shrimp and crustaceans. Carotenoids are well-known for their anti-aging benefits and their abilities as antioxidants to help prevent certain chronic disease conditions.

Here are a few science-backed uses of astaxanthin.

As an Anti-inflammatory

Chronic inflammation is a major factor in several diseases, including hypertension and diabetes.

Like other carotenoids, astaxanthin has been researched for its effectiveness as an anti-inflammatory agent. In an 8-week study on the effectiveness of dietary astaxanthin on immune response and inflammation in healthy adult females, inflammation was decreased in the group who were given astaxanthin when compared to those receiving placebo.

For Healthy Skin

Researchers have also explored the skin health benefits of astaxanthin. In a 2012 study, women who supplemented with 3 milligrams per day of oral astaxanthin and used a topical astaxanthin product for 8 weeks had fewer wrinkles and age spots as well as more skin moisture and greater elasticity than those who had not used the supplement.

Another study published in 2018 found that dietary supplementation with astaxanthin protected against UV-induced skin damage and helped keep skin healthy.

For Eye Health

Age-related eye diseases that result in vision loss, like macular degeneration or AMD, affect more than 6 percent of Americans over the age of 40.

In a two-year study on AMD patients, supplementation with astaxanthin and two other carotenoids (lutein and zeaxanthin) improved visual acuity and contrast sensitivity.

While there is no recommended dose of astaxanthin, clinical studies have demonstrated health benefits in doses between 3 to 8 milligrams per day.
