ALA, which is found in terrestrial plants, is a type of Omega-3 that is not in a form that your body can efficiently use. What we mean is that your system has to convert all land-based (short molecular chain) Omega-3 to long chain ocean/marine based Omega-3 (DHA & EPA)  for it to be bioavailable. This process is quite inefficient. We would also note that you are unable to digest any flax seed that is swallowed whole so ground flax is preferable. We estimate that it would take 8 tablespoons of ground flax to match the bioavailability of 300mg of DHA, assuming that you convert at an average rate. Put another way, DHA is around 20 times more bioavailable than ALA, so it’s highly recommended to use an algae-based oil. We sure would appreciate it if you buy our products,but if you choose not to,we strongly suggest you take algae oil daily. It’s for your health! You cannot solely rely on ALA – hemp, chia, nuts and or Flax.
