Good post with good information, especially on DHA, which indeed has solid science behind it. And there are non-fish sources, if you decide to use supplements, like Life's DHA as an algae-based ingredient. Regarding supplements overall, there is certainly a mixed bag, with a lot of hype. If it sounds to good to be true - it is! There are also, though, well-substantiated products in some supplement categories. Looking forward to following this series as well.
