I have had moderate psoriasis for many years. My father had it worse. About 5 years ago I learned about a recently discovered third variant of the B-3 vitamin, Niagen (nicotinamide riboside, or NR). I took 300 mg at first, but take 900 mg per day now. At first I noticed that I no longer had muscle inflammation in the mornings - after taking it for about 7 weeks. Over time, but especially after upping my dose to 600 mg, my psoriasis ent gradualy away, except that there is s little left on one knee, while my feet, elbows, and the other knee went completely smooth. I told others about it, and they got relief from restless leg syndrome, neuropathy from chemo, and carpal tunnel syndrome. I will never stop taking it. Here is the report I saw today regarding psoriasis: https://www.businesswire.com/news/home/20231002427548/en/A-Milestone-Clinical-Study-Reveals-that-Elevating-Nicotinamide-Adenine-Dinucleotide-NAD-with-Nicotinamide-Riboside-NR-Supplementation-Effectively-Reduces-Inflammation-in-Both-Healthy-Subjects-and-Immune-Cells-Derived-from-Psoriasis-Patients?fbclid=IwAR1Fqa99UETwiXlB82590dGsEar8bqlzwef8iycZoRaMxfazDgGLMZUkMw8
