Vitamin B-1 for Stuttering

Vitamin B-1 for Stuttering Okay, I’m looking into Vitamin B-1 to help my stuttering problem. And I don’t know whether to take the vitamin or just get speech therapy. Vitamin B-1 can help stuttering but can have some side effects, such as itching, swelling in the face and restlessness. So I’m not sure if it will be beneficial for me because of the side effects. People who take the vitamin, have you had good results?
