Every day for about 20 years I've taken a daily cod-liver oil or Omega 3 supplement. Yes, I know I should get Omega 3 by eating oily fish twice a week, but realistically I'm not going to do that. For the last 2 years I've added a vitamin D supplement on GP's advice. I never get colds or flu, skipped all the covid despite working throughout, have healthy blood pressure and in my mid 60s still work full time. It feels almost like a superstition to take Omega 3 now. I'm not sure the evidence for it helping brain health is even that strong. AIBU to continue taking fish oils daily? What supplements do you swear by and why?
