Study investigates how vitamin D or omega fatty acids may affect rates of autoimmune diseases

Autoimmune diseases (AD) such as rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease and psoriasis, are a leading cause of morbidity and mortality as people age.

Effects of multi-nutrient supplementation on COVID-19 severity in elderly patients

In a new study, researchers analyzed the effects of multi-nutrient supplementation on SARS-CoV-2 vaccine efficacy and the overall improvement of respiratory and muscle function in elderly COVID-19 patients.

27 Jan 2022

Daily supplementation with vitamin D and fish oil may lower the risk of autoimmune disease

Taking daily vitamin D supplements - or a combination of vitamin D and omega-3 fish oil - appears to carry a lower risk of developing autoimmune disease, with a more pronounced effect after two years, finds a trial of older US adults published by The BMJ today.

Targeting SARS-CoV-2 M protein may help ease severity of COVID-19

A new study, published on the medRxiv preprint server, focused on the production of human CD4+ T cell lines (TCLs), reactive to either S or M protein, and analyzed if the S and M structural proteins had intrinsic differences in driving antigen-specific CD4+ T cell responses.
