The study, published online in the Journal of Nutrition, was one of the first to directly compare the effects of two of the
omega-3 fatty acids often cited for their nutritional value,
DHA and EPA.
In research with laboratory animals, it found that EPA had comparatively little effect on preventing the fibrosis, or scarring, that's associated with NASH. However, DHA supplementation reduced the proteins involved in liver fibrosis by more than 65 percent.
