A Dunaliella salina microalgae extract processed to make its natural carotenoids easier for the body to absorb. The key carotenoids are beta-carotene and zeaxanthin. Compared to standard algal powders or whole-cell supplements, this form is absorbed better and tolerated more easily.
Most people take it to support eye health, including macular health and protection against blue light, and to reinforce skin's antioxidant defenses against UV stress. Others take it as a general antioxidant to help maintain immune function.
Take this extract once daily with a fat-containing meal. That step helps your body absorb the carotenoids. Common doses do not cause major drug interactions, but high beta-carotene intake can produce harmless yellowing of the skin called carotenodermia. A theoretical interaction with retinoid medications exists.
