Hello friends.
For the few weeks I been trying to get in better shape, eat better and take my vitamins.
I went to the local nutrition house and got some vitamins (Vitamin B3 (500mg niacin), Vitamin B12 (250mcg), Vitamin C (500mg), Beta Carotene (30,000 IU), Vitamin E (200UI). I also take the Centrum Forte multivitamin.
Ok the thing is, I though I was going to have a heart attack (litteraly).
First day I took all of these vitamins together, and two minutes after I started to get really hot, and itchy. After five minutes, my whole body feelt like it was really sunburned, I had red rashes all over my body and my head felt like it was going to explode (the feeling you get when hanging upside down for 5 minutes when all the blood rushes to your head).
This was a somewhat strange experience, I really though my blood pressure is high, but I noticed that this happens EVERY time I take this combination of vitamins.
Does anyone know what vitamin can be cuasing this? Here is the rundown again.

Vitamin B3 (500mg niacin)

Vitamin B12 (250mcg)

Vitamin C (500mg)

Beta Carotene (30,000 IU)


Vitamin E (200UI)
