I've read somewhere that you shouldn't take your oil and fatty acid supplements (fish oils, flax, safflower, CLA, etc) at the same time as a high fiber meal or say with psyllium husks which are fiber. Apparently the fiber absorbs the oils and prevents them from being utilized by the body. They basically pass through your system bonded to the fiber.
I now take my psyllium husk in the morning and divide up my oils between afternoon and nighttime. Especially those yucky fish oils are good to take at night so I don't burp up a fishy taste during the day.
