By David Liu, PHDSunday July 8, 2012 (foodconsumer.org) -- A new review article published recently in the American journal of Clinical Nutrition suggests vitamin d3 is more efficacious than vitamin d2 in raising serum 25-hydroxyvitamin D.Both vitamin D3 made from some animal like wool and vitamin d2 made from a plant source like mushroom may be available as supplements although vitamin d3 is more commonly seen on the market. Both are believed to be helpful.The meta-analysis of previous trials led by Laura Tripkovic of University of Surrey, Guildford, United Kingdom and colleagues showed "supplementation with vitamin D3 had a significant and positive effect in the raising of serum 25(OH)D concentrations compared with the effect of vitamin D2."Vitamin D has been found associated with more than 100 health conditions including obesity, diabetes, heart disease, and cancer, according to Vitamin D Council.
