Eye Health

You may have heard that carrots are good for your eyes. Carrots contain carotenoids, a family of compounds that help protect the eyes, so there is some truth to this old adage.

Astaxanthin is one of nature’s most powerful carotenoids (much stronger than carrots), and one that can actually cross the blood-retinal barrier which separates your bloodstream from your eyes. As such, astaxanthin can directly benefit eye health.

Oxidative stress is associated with the formation of many eye disorders, like age-related macular degeneration (ARMD) (1). The eye is particularly susceptible to this oxidative stress and astaxanthin has been shown to prevent oxidation of lipids in human lens cells (2). Another study observed astaxanthin reducing oxidative stress and inflammation in the eye of animal subjects (3).

Macular degeneration is one of the leading causes of blindness in the United States in people over 50 years of age. In combination with other antioxidants, red algae astaxanthin was shown to improve vision in patients at risk for AMD (4). Astaxanthin has also been shown to reduce eye strain and fatigue, which may result from excessive exposure to blue light from computers and other electronic devices (5).

The evidence is mounting, astaxanthin can be a powerful ally in eye health.
