Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Dunaliella salina is a type of microalgae notable for its exceptionally high content of natural carotenoids, particularly beta-carotene. Beta-carotene is a well-known precursor to vitamin A, a nutrient essential for maintaining healthy vision. Scientific studies have demonstrated that beta-carotene supplementation can help prevent vitamin A deficiency, which is associated with a range of eye disorders, including night blindness and xerophthalmia. Additionally, carotenoids like beta-carotene possess antioxidant properties that may help protect ocular tissues from oxidative damage related to aging and environmental stressors, such as UV light exposure.

However, while Dunaliella salina is a rich natural source of these compounds, most clinical studies on eye health have focused on beta-carotene or mixed carotenoid supplements rather than on Dunaliella salina itself. The use of Dunaliella salina as a dietary supplement is primarily justified by its beta-carotene content, with indirect evidence supporting its benefit for eye health via this mechanism. There is a moderate level of scientific validation for carotenoids in general supporting eye health, especially in the context of preventing deficiency and potentially reducing the risk of certain eye diseases, such as age-related macular degeneration, when consumed as part of a balanced diet. However, more direct clinical research on Dunaliella salina itself is limited.
