Following my post yesterday about the British television show "Doc Martin" and the use of placebos, I deliberately avoided revealing what the placebos actually were in order not to distract from the main points I wanted to raise. The "placebos" that Doc Martin and his predecessor gave the patient were vitamins.
Now, if you, like me, are a fan of another doc, "Doc" Abram Hoffer, you may object to calling vitamins, "placebos." Niacin in very high doses in combination with an equal amount of vitamin C and other B-vitamins, is very effective in reducing psychotic symptoms, anxiety, and increasings one's focus. Ever since I learned about niacin and started giving it to Chris to help his psychosis, I also put myself on three grams per day of niacin,vitamin C, and I added a B-complex and zinc. I got amazing results in just three days. My ability to focus increased about five-fold, my hair got thicker and my skin got smoother. I was less anxious.
People are unique in their nutritional needs. People under stress need much larger amounts of certain B vitamins than they get from eating an otherwise healthy, well-balanced diet. Smoking depletes vitamin C, alcohol depletes the B vitamins, and so on. Don't assume that vitamins are worthless just because someone calls it the placebo effect.
