I am a big believer in vitamin B. I've read in several books that it can help reduce anxiety.
I know firsthand though, that if you have any weird tingling sensations, or numbness, or tiredness while anxious, it definately helps get rid of those sensations. It definately helps me.
When I first started taking a vitamin B-complex, I felt a little jittery, but that stops quickly and you really can feel the difference.
Here is a part of an article from

"VITAMIN B COMPLEX DEFICIENCY:
MAJOR CAUSES
Vitamin B complex comprises a number of vitamins that exist as a family. They should not be taken individually. In this modern era, millions of people suffer from a deficiency of vitamin B for several reasons, chief among which are:
Stress: emotional, physical and spiritual
Processed foods in the diet: these are not real foods and so they tax the body
Refined sugar. The average person consumes at least 140 pounds of sugar a year which robs the body of its vitamin B stores
Drugs: both recreational and prescription drugs deplete vitamin B
Toxins: poisons in the environment and personal care products deplete vitamin B complex
Malnutrition. Most people are malnourished because they are not eating the right kinds of foods
Cooking. Most people do not eat enough real, raw foods, so vitamin B is killed or so depleted that people are not getting enough of it in the diet
DO YOU HAVE ANY OF THESE SYMPTOMS?
Once your body has been deprived of the vitamin B complex due to reasons stated above, it begins to show symptoms (signs) of altered, diminished or poor health. This is because the vitamin B complex (within foods, not vitamin pills) is responsible for such a wide variety of activities, including cellular differentiation, transmission of nerve electricity, health of nerve cells, heart pulse rate, muscular contraction, digestion, brain function, thought processes and energy production. Without adequate vitamin B complex from foods, you can experience one or more of any one of these symptoms:
mental problems
heart palpitations
heart arrythmias
fibrillation
indigestion
chronic fatigue
chronic exhaustion
paranoia, vague fears, fear that something dreadful is about to happen
nervousness
ADD (attention deficiency), inability to concentrate, irritability
feeling of uneasiness
thoughts of dying
easy agitation, frustration
inability to sleep (insomnia)
restlessness
tingling in hands
fingers and toes
rashes
crying spells, inability to cope
soreness all over
and so much more.
