According to a new study from Japan a daily supplementation with EPA-rich fish oil may boost exercise economy, a predictor of endurance exercise performance.
In the randomized controlled trial, blood concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) as well as oxygen uptake (VO2) during steady-state submaximal exercise were measured in 20 healthy college-age males, who received a daily fish oil supplement with 3.6 grams EPA or placebo (triglycerides) for eight weeks (1). The study results showed that blood (erythrocyte) EPA and DHA levels increased significantly by 148% and 13%, respectively, after fish oil supplementation, while no such increases were observed in the control group. Data from cycle ergometer tests indicated that the more EPA was in the red blood cells the lower was the oxygen uptake during the exercise.
The researchers concluded that these findings suggest that an EPA-rich fish oil supplementation improves exercise economy and reduces perceived exertion. Because there is a strong relationship between exercise economy and endurance capacity, fish oil supplementation may also enhance endurance capacity by improving exercise economy. The mechanisms behind these effects are not clear so far.

The immune system plays an important role in fighting tumors. Adequate blood concentrations of vitamin D can help to strengthen the immune system and ensure that immune cells are functioning properly. It is also suggested that certain immune cells have the ability to convert vitamin D into its active form. In addition, vitamin D seems to be able to bind to cancer cells and instruct them to die or stop growing. Thus, vitamin D supply status may be related to the risk for cancer development.
