B3 overdose is dangerous if you have susceptibility to gout. This happened to me after I inadvertently megadosed by consuming a knock-off Berocca drink containing something like 10x RDI. That was over 10 years ago. I have not had a gout attack since. Edited: Risk is actually for Vit B3 (Niacin). The drink I had contained massive amounts of B12, B3 and others. https://www.mayoclinic.org/drugs-supplements-niacin/art-20364984 https://www.mayoclinic.org/drugs-supplements-niacin/art-2036...
