I bought Bob's Red Mills Chai Seeds. It states it has Omega-3 2900 mg Omega-6 1100mg Whole Chia Seed this is for a tablespoon. So my question is how much of my omega 3 needs daily does this fill? I do eat fish such as salmon,some walnuts,etc but I am trying to get more omega 3 and not through more pills. Also if I get wild salmon is there still a concern about mercury and the amount weekly should be limited?Thank you
