Omega-6 is a type of polyunsaturated fatty acid and an essential aid to good health. Omega-6 protects the heart, promotes skin and hair growth, improves bone health, and regulates the metabolism.
How much you should have: Approximately five to 10% of a day's worth of calories should come from omega-6 fatty acids, though really, the key is to balance your omega-6 intake with a healthy dose of omega-3.
As a rule of thumb, take in twice as much omega-6 as omega-3. Food sources alone tend to deliver enough omega-6, meaning supplements are not usually required.
