Palmitate retinol. Suggested daily use is silly. Do I look like someone who takes recommended dosages??? lol. This stuff has the longest half life ever. Look at how much C we take compared to recommended doses. I don't know about absorption differences. But I do know that there retinoids (in animals) and Carotenoids (found in plants) are not made equal. While similar, there are unique benefits to each. I've been taking powder form for a long while now, never really looked too much into carotenoids.
