i went to gnc yesterday to get some flax seed oil and all they had were these gelcaps. i'm getting it to add some calories to my diet but these little 500mg gelcaps only have 5 calories per pill. it says take 1-2 daily...is that enough? how many of these 500mg caps would be equal to 1 tbsp. i was told to take 1-2 tablespoons daily.
