Beta carotene is as it is and you cant overdose on it.The liver converts beta carotene to pro-vitamin A which is a fat soliable vitamin than can become toxic.The self regulation of the body will not poison itself so beta carotene is never a problem.If food pigments changed skin color than one could become green from grass and blue from blueberries,this doesnt happen.Skin issues are a sign of constipation on a digestive and ultimatly on a cellular level.Life and death begin and end in the bowels.Maximize the workings of elimination and the blessings of life will flow in abundance.Be well,Jeff.
