I take 1 tablet three times a day. Mine is both b12 and folic acidMy nutritionist has me doing 5000 mg's under the tongue with Sublingul. It is very very hard to overdose on b12 according to one of my doctors. He said b12 and d3 are Crohn's happy vitamins. I do liquid versions of both, the latter I mix in applesauce.
i wouldn't do anything without asking my doc. too much b12 can worsen things.I have mild to moderate Crohn's. My tongue is sore, which is a symptom of vitamin B12 deficiency. I am going to take a B12 supplement. Is there any way to determine how much (micrograms) to take each day?
