Question

why consuming large amounts of vitamin A is more dangerous than consuming large amounts of vitamin C?

Answer 1

Overconsumption of vitamin A can cause rashes, headaches, drowsiness, nausea, irritability and problems in muscle coordination.  When symptoms develop it would be best to decrease your intake of vitamin a supplements for at this point it does more harm than good.  Unlike vitamin a, overconsumption of vitamin c only leads to excess to leave the body through fluids.  Still it is better to maintain balance intake to avoid any health problem.
