Many
supplements use a pink micro-algae called Dunaliella salina as a source
of carotenoids. These organisms live in highly saline conditions and grow in
intense light which causes them to produce high levels of beta-carotene. This
algae is not a normal part of the human food chain. GNLD Carotenoid Complex
derives carotenoids from foods you would find in your grocery store.
There are many different carotenoids and each has a specificity of action. The
carotenoid profile of foods is altogether different than the profile found in
algae. There is also a competitive inhibition of absorption of one carotenoid by
others. This means that use of high quantities of carotenoids from outside the
food chain may impair absorption of some carotenoids robbing the body of the
beneficial effects which may be unique to carotenoids found only in
foods.
