Doctors often prescribe large doses of Vitamin B3 to help patients suffering from various mental problems, including a persecution complex. The vitamin is destroyed by alcohol, contraceptive pills, sleeping pills and sulfa medication.
You can enhance medical treatments by eating foods rich in Vitamin B3. Generally speaking, B3 is found in many foods, especially pork, beef and veal liver, whole grains, fish, white meat, eggs, dates, figs and almonds.
The daily recommended dosage for adults is 15 to 20 milligrams. Larger doses (50 to 100 milligrams) can be taken without danger, in the form of nicotinamide, to compensate for a deficiency.
