Dunaliella salina


Dunaliella salina is unicellular green halophilic micro-algae specie which grows in high salt concentration environment. D. salina has adapted to high solar radiation by producing a mixture of carotenoids, mainly β-carotene, to protect itself against ionizing energy.

The accumulation of the carotenoids gives a peculiar pinkish-red colour to the organism. This survival tactic of the micro-algae makes it one of the most potent sources of natural β-carotene, a pro-vitamin A having tremendous importance in terms of visual health.

Dunaliella’s rich nutritional profile of high quantity anti-oxidants along with a vast spectrum of vital phytonutrients makes it a fitting active ingredient in the nutritional and cosmetic industry.

Natural Beta-carotene from Dunaliella salina

Natural beta-carotene is a pro-vitamin A which is converted to retinol (Vitamin A) in the body as required.

Dunaliella salina comprises of all-trans β-carotene, and the equivalent stereoisomers, 9-cis, 13-cis and di-cis β-carotenes in equal amounts. 9-cis β-carotene is of particular nutritional and medical interest as a retinoid precursor, RXR. It is associated with therapeutic effects in a number of macular diseases.
