Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Haematococcus pluvialis is a microalga recognized as the richest natural source of astaxanthin, a potent antioxidant carotenoid. Scientific studies have investigated astaxanthin's effects on eye health, with several clinical and preclinical trials suggesting benefits. Astaxanthin can cross the blood-retina barrier, allowing it to exert antioxidant effects directly in ocular tissues. Research has shown that astaxanthin supplementation may reduce oxidative stress in the eyes, improve retinal blood flow, and alleviate symptoms of eye fatigue, particularly in individuals exposed to prolonged screen time. Some randomized controlled trials have reported that astaxanthin supplementation supports accommodation (focusing ability) and reduces eye strain.

Furthermore, animal and in vitro studies suggest astaxanthin may protect retinal cells from damage induced by light exposure and oxidative stress, both of which are implicated in age-related macular degeneration (AMD) and other degenerative eye conditions. While more large-scale, long-term clinical studies are needed for definitive conclusions, the current body of evidence provides a reasonable scientific basis for using Haematococcus pluvialis (through its astaxanthin content) to support eye health.
