The body takes fatty acids from Omega 3 and Omega 6 and transform them into powerful substances called prostaglandins. Prostaglandins are used by every tissue cell and organ in the body to regulate and control. When something needs to be done the body will take some fatty acids, turn them into  prostaglandins and get the job done. i.e. movements of calcium and other substances, dilation and contraction, inhibition and promotion of blood clotting, regulation of secretions including digestive juices and hormones, control of fertility and sexual relationships.

As such, our body requires a good balance of Omega-3 and Omega-6 fatty acids so that it can use prostaglandins to fine tune the work that needs to be done.

Along with hormones, these are very powerful and complex substances and can be easily influenced by external factors through diet. Our emotions as well as stress can alter and influence the way these natural body chemicals work.
