Supplement with flush-free niacin (vitamin B3), 500 m.g. with each meal (always with food). Schizophrenia is symptomatic of deficits in vitamins B1 & B3. Research Abram Hoffer (the late M.D., bio-chemist & co-creator of Orthomolecular medicine). Dr. Hoffer gradually weened his schizophrenic patents off lithium-based psychiatric drugs. There were many positive testimonials on YouTube from Dr. Hoffer's former patients, but these videos have been removed.

Niacin that isn't labeled "flush-free" often causes a harmless (false) allergic reaction: red skin & itchiness that lasts 15 minutes (a shower lessens the reaction).

Dr. Abram Hoffer's videos, that were on YouTube several years ago, concerning vitamin B3 as a successful treatment for mental illness are on BitChute.
