Take a fish oil supplement every morning with your breakfast.  

The alternative to supplementation is to have two servings of oily fish a week. Most of us don’t get that - hence the supplement.

ACTION PLAN

1. Choose a good quality supplement.  
2. You may have to do some experimenting with different supplement ranges. I always thought that the Omega-3 thing was a bit of a waste of time. I bought the brand that I am currently taking because it was on special. After about a month on it, I could honestly say that I felt that it was making a difference.
3. It is best to take these with meals to stop the flavor from repeating throughout the morning.  
4. If you do not like fish, you are not initially going to like the fact that the flavor does repeat on you. But that will go away in time.
