At 7:32 Seth mentions how someone said this could be placebo effect, and he said that his friend (Tucker) stopped taking flaxseed oils and that his gums got worse. I feel like placebo could easily throw away all his results into nothing, and can only hope that maybe one day he will try experiments to try to confirm if placebo is just as effective instead of trying to disprove placebo effect ineffectively by stopping flaxseed oil for a bit. I've experimented with several sources of omegas and antioxidants, and have in turn become very skeptical about these sort of things. I've noticed a lot of people really talk up a lot of different supplements and how they greatly enhance certain abilities only to be very disappointed after paying buckets full of money for them. I think exercise and a good (varied) diet are way more important then supplements (or uber strict diets), but even then haven't noticed any huge performance gains from such things.
