helps migraines

Posted by Reviewer3268719 on Nov 30, 2011

My son has suffered from headaches for years. This is the first and only thing that has showed some improvement on his migraine headaches. He used to get them almost every day. Now it is only a couple times a week. He takes 2 of the 100mg daily. We are increasing the dose to 3 of the 100mg daily. I do wish they would make a high mg pill though.

Seems to be working

Posted by Reviewer2148303 on Aug 23, 2011

I was told to take 400 MG for migraine and was worried because of bad reactions to other B vitamins (the flush!). This seems fine though, easy to digest, and I've only had one almost migraine since I started taking it. I was told it would take several weeks to get to the right level in my blood, so I have my fingers crossed! I've had migraines for 25 years.
