Lysine is helpful for "cold sores" (oral herpes).

@Wheatwacked, Are you aware of the interaction of potassium iodide and losartan ?   https://www.drugs.com/drug-interactions/iodine-potassium-iodide-with-losartan-1368-0-1489-0.html#:~:text=Talk to your doctor before,to safely use both medications.

As a life.long celiac, I understand this.  I simply ask that the medical profession stop disregarding the fact that it should remain a concern for some. It cost me a lot of medical discomforts.

@dmallbee, about 8% of celiacs react to the oat protein avenin like they do to the wheat protein gluten. In addition, there are some cultivars of oats that apparently do actually contain gluten.

I was diagnosed at 18 months old with celiac and lived without wheat, rye, oats, and barley as instructed by my doctor, Dr. Katz at Boston Children's Hospital in the 60's and 70's. I don't agree nor recommend doctors removing oats from restriction, certified gluten-free or not.  I have eaten certified gluten free oats and have had the usual reactions to gluten.  Please reconsider this with newly diagnosed patients.
