Many thanks to Jennifer from Northern Idaho. I tried the flax seed oil capsules and my canker sores have not appeared since. I had taken lysine capsules for two years when one day the canker sores reappeared. The flaxseed capsules have worked beautifully. Highly recommended.
Flax Seed Oil
I was having chronic canker sores, usually 3 at a time. I tried everything I'd ever heard of with little success. I started taking Omega 3 in the form of flax seed oil for general health reasons. Within a week or so my sores were gone and I haven't had one since. I alternate between flax oil capsules (6 a day), ground flax seeds (2 tablespoons) and eating about 1/4 cup of walnuts.
