sleep effect?
placebo effect?
how many g’s of omega-3 would you recommend taking per day? do you think it matters what form it comes in (flaxseed oil, fish oil supplements, real fish, etc.)?
I haven’t gotten far enough to answer your excellent questions. I can only say that 3 tablespoons/day of flaxseed oil seems to produce better results than 2 tablespoons/day.
