A recently published article in Bioscience, Biotechnology and Biochemistry (Kawabata, 2014) suggests that a daily dose of 3.6g of fish oil can improve exercise efficiency.

In a double-blind study, the group of healthy male subjects, supplemented with EPA-rich fish oil, experienced a decrease in oxygen uptake needed for sub-maximal exercise. They also perceived the exercise as being easier.

This points to an increase in exercise economy, which is linked to an increase in exercise endurance.

A sachet of KetoactiveMind contains 3.5g of high quality fish oil rich in EPA and DHA in a tasty shot.
