My 7 year old daughter who has ASD has been taking many vitamin and mineral supplements for the last 10 months which are helping her. Problem is, for the last 3 and half months she is getting severe migraine headaches daily. These throbbing, pounding headaches usually start from her right temple. The headaches started after recurrent viral and bacterial infections. The only supplement that I started a week before the onset of headaches is sublingual MB12. She is taking 800mcg. Can anyone please help me by telling, if MB12 drops can cause migraine headaches?
