Interesting new Clinical trial study see here and here:
"A question most physicians hear almost daily is “Doctor, which vitamins or supplements do you recommend that I take?” This was a question that my colleagues and I set out to answer in the Autoimmune Disease Prevention ancillary study in the VITAL trial.1 Now, when my patients, colleagues, or friends ask me, I can point to our research findings, which suggest that for women age 55 years and older, and men 50 years and older, marine omega-3 fatty acids (fish oil) 1000 mg a day, and vitamin D 2000 IU a day—the doses used in VITAL—lead to a 22% reduction in all autoimmune diseases with vitamin D, and a 15% reduction in the same with fish oil supplementation over 5.3 years of randomised follow-up. In the trial, these supplements were prescription grade and underwent rigorous quality testing. They were safe and well tolerated and no increase in adverse events was found. For individuals obtaining these supplements over the counter, I also recommend that they check the safety seals for quality assurance as these products are not always as well tested."
