I found this excellent guide for blessings for food, drinks, meals, snacks for Noahides. Also, Orach Chaim course has been an excellent guide for us in this aspect. https://asknoah.org/faq/short-blessing-after-food
One question I have is, how about vitamins, supplements, or medicines? Should we also bless Hashem before eating/ingesting those too? (Nowadays certain kinds of vitamins or medicines are made to taste like snacks and pleasurable to eat. Even if they don't taste good, since I am benefitting from them, I wonder if I should bless Hashem.)
Thank you so much for considering my questions!
