Flax seeds are a rich source of fibre and also multi nutrients such as Vitabin B1, Manganese and a very rich source of Omega 3 which is very good for heart and skin. Yes I have been taking 2 spoon full of flax seeds for last 2 years and there are visible benefits of doing so. My cholesterol levels are in control and also digestion is good. When you take falx seeds remember to drink lot of water otherwise it may lead to constipation.
Other factor to consider is to increase the consumption slowly. This may disturb your bowl for a short time till your body gets used to it.
I simply ground the seeds and put them in roti batter and take it. You can take them in any form like in chutneys, on bread etc but regular with roti is best in my view.
I have no idea on organic and inorganic and I dont think that should have any impact.
