Beta-carotene absorption is quite a challenge because it's an extremely water-insoluble compound, which is why it's best consumed with fats. It's probably likely that you're absorbing some of it, but not all, that's what most people do. Most... (more)

Eat some liver. 3-4 oz per week should be sufficient. Sounds like you need some retinol and your body isn't able to convert all the beta-carotene you are consuming.

Beta carotene, as found in plants, does not cause hypervitaminosis A. We only convert what beta-carotene we need to vitamin A. You might start to turn orange from all the beta carotene though. See: http://en.wikipedia.org/wiki/Beta-Carotene (more)
