"Vitamin D and Omega-3: Key in Preventing Autoimmune Diseases"
A study following up on the VITAL trial found that while the protective effects of daily vitamin D supplementation for reducing risk of autoimmune diseases waned after discontinuation, the benefits of daily marine omega-3 fatty acid (n-3 FA) supplementation remained significant for at least 2 additional years. The study suggests that vitamin D supplementation should be continuous for long-term prevention of autoimmune diseases, while the benefits of n-3 fatty acids may persist after discontinuation. Different autoimmune diseases showed varying responses to the supplements, with vitamin D appearing strongest for psoriasis and n-3 fatty acids for rheumatoid arthritis and inflammatory bowel disease.
