Do you know how tryptophan gets converted into niacin. Tryptophan can go 2 ways serotonin or niacin. How do we shuttle it into niacin instead of serotonin because just taking niacin doesn't solve the problem of all our tryptophan turning into serotonin.There are studies by Hoffer, Saul, etc from doctoryourself.com about niacin being used on concentration camp victims, alcoholics, people with mental issues. I consider these people to be in "really bad shape and near death." Something about niacin restoring progesterone? This is how I view people who have been vaccinated.
"This observation raises some interesting speculations. Women, on average, live longer then men. It has been shown for men that giving them niacin increases their longevity. [2] Is the increased longevity in women the result of greater conversion of tryptophan into niacin under the stimulus of their increase in estrogen production? Does the same phenomenon explain the decrease in the incidence of coronary disease in women?"
"Dr. Hoffer has treated thousands and thousands of such patients for nearly half a century. At 83, he still is in actively practicing orthomolecular (megavitamin) psychiatry. He has seen medical fads come and go. What he sees now is what he’s always seen: that very sick people get well on vitamin B-3."
I always come back to Ray Peat, Hoffer, Saul who basically promote the opposite of what they teach doctors in medical school.
