Vitamin C and yellow stool

Hi brothers and sisters.I have a question. The thing is that i did injections of ascorbic acid 3gr(200mg every 1,5 hrs)and it really works for me,i feel better!!But now I don't have the opportunity to do it ,my butt all in bruises and i simply don't have a time etc.I bought C-1000 by "Now foods",drink 3 capsules every 5 hours...and my stool became yellow,but without diarrhea nor pain etc..(and also it seems that there are undigested pieces of food in it,but i could be wrong about it).Is it normal that the colour has changed?Thank you.
