My son is 21 he gets random nose bleeds mostly at night while he sleeps. He grew up taking flintstones vitamins daily and as a adult he is not a daily vitamin taker he has taken iron pills from time to time, thinking with all the blood lose it is probally a good ideal. When he doesn t take the iron it seems to make his nose bleeds more common. Is there a relationship between the two? He has given blood many times in his life, thru high school, with no problems from it, he has never been found to be anemic. ????
