For a balanced production of prostaglandins, adequate intake of omega 3 fats is important. Prostaglandins help regulate various functions, which include nerve clotting, blood pressure, nerve transmission, allergic responses and inflammation. Moreover, it also regulates the functions of the kidneys, GI tract, and other hormones production.

However, it has also been claimed that over dosage can have adverse effects such as allergies in infants.
