What is your opinion (Rich / David) on using high doses of the supplement Niacinamide for joint pain/osteoarthritis?
it is referenced in this article: https://isom.ca/wp-content/uploads/Niacinamide-Therapy-Pioneer-William-Kaufman-MD-PhD-as-Remembered-by-his-Wife-Charlotte-30.1.pdf
And specifically in a study by Dr. William Kaufman: https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/554657
