I suffered from SAD from the age of 14 quite possibly from the age of 10 until the age of 40. it was hell then at the age of 40 I started taking Omega 3, it didn't work on my depression for 7 months, the Omega 3 seemed to work on my body first before moving on to curing my brain problems. Fact: 24% of the brian is made from essential fatty acid of which omega 3 is one. Omega 3 also cured loads of problems I had, loads of. them. This is maybe the only post I am going to post on the subject.
