Same reply as to the canker. I take vitamin C routinely. with my family , friends etc it seems when allergy, uri, virus symptoms arrive (scratchy throat is one of mine) the c helps. I routinely take 500 mg once a day. When symptoms arrive I take these two or three times a day & then add a 100 mg tablet of zinc a day to supplement. Our diets of refined, processed, etc kill much of the food value that was originally there. Good luck & continue to have doc monitor for possibility of serious problem.
