Although I can’t speak about flaxseed helping smooth out levodopa absorption levels, it is however an excellent and healthy way to help alleviate and/or prevent the discomfort of constipation.

I have used flaxseed for over a decade, adding it to everything thing from oatmeal, cereals, yogurt, smoothies, baked goods, meatloaf, meatballs, etc. Be sure to use ground flaxseed (whole seeds will not be absorbed) and refrigerate the open package. Give it a try, add 1-2 tablespoons to your diet, slowly. It has a nutty flavor, much nicer than the “orange” drink!
