I digest grounded flax seed almost everyday with my J Pouch, I only eat about 5 grams of it, but it's been one of the friendlier foods I've consumed.

thank you what about the gelcaps digesting though?

Since gel caps are made to dissolve my guess is you wouldn't have much of a problem with them. You're probably better off with the crushed flax seeds though if you can find them in gel caps. I consume my flax seed mixed with milk and oatmeal in the morning. It's one of the better foods I've used since my J Pouch was installed.
