What about the pill form? How much would you take and does it have to be taken right after a meal?

1 capsule or by directions. Before, during or after the meal.

Just what I need, another supplement to take!

I don't need the l-glutamine when I'm on the right dose of vitamin D.

This may sound... strange, but it may work for you. Buy a mouth gaurd, like for football or whatevery and when you not eating put it in your mouth. It might just work...
