CVD treatment watch

Scientists suspect omega-3 fatty acids could slow acute wound healing

They are supposedly good for the heart, but this popular fish oil used by many as nutritional supplement seems to slow down wound healing, according to researchers at the Ohio State University. In their research, they compared the healing process of blister wounds of people taking omega-3 supplements compared to those taking only placebo. Although healing seemed to have proceeded almost at the same time in the two groups, something different was observed at the cellular level. There were more proteins associated with initiating and sustaining inflammation observed in the blister fluid of those who were taking the active supplement. The researchers expected exactly the opposite and are still trying to figure out the mechanisms behind this.

These findings are very significant because many heart patients are on omega-3 supplementation. If healing is indeed slowed down by these supplements, then such supplements are not suitable for patients scheduled for surgery.
