 All of our I-vitamins, we have no beta carotene in that. As a matter of fact, we were a study site. We did the Blaze study, beta carotene, lutein, alpha carotene, zeaxanthin absorption study. This is years ago, proving that beta carotene actually blocks the absorption of carotenoids, lutein, and zeaxanthin. That's before we even knew a lot about astaxanthin. So those are all in the xanthophyll family. It might even block astaxanthin.
