Effect of Vitamin E

I took Vitamin E (250 IU; d-alpha-tocopherol 167.5 mg) in the morning for few days. I experienced severe headache for almost the whole day. However, I observed one strange effect. If I take vitamin E together with a boiled egg, then I did not get any headache.

Positive effects:

• Reduced anxiety
• Able to work continuously with focus and concentration without getting much tiredness and it was helpful for writing articles at one stretch.

Negative effects: 

• Stuttering was mild. However, mild vocal blocks were there during the conversation. The speech was easy to start but after talking for 10-15 minutes, suddenly I was stuck with a vocal block in which I was unable to produce any sound from my throat. I could not even stutter. This vocal block was similar to the one I observed with DL-phenylalanine.
• Severe headache on right side of my head (indicating dopamine deficiency)

This vocal block might be probably due to the low level of dopamine. There is a research paper supporting this hypothesis.
