• The standard dose to maintain optimal health is minimum 500 mg per day.
• For people suffering from dyslexia and dyspraxia, 500 mg per day is sufficient.
• For those suffering from ADHD, a dose with a 500mg to a 1g is recommended.
• For people with Depression and mood disorders a dose as 1000 mg EPA will be adviced.  

In order to take in the recommended standard dose of EPA, you should eat 230 g of fatty fish daily or 860 g of less fatty fish. That's not a very practical solution as most people in the community don’t eat enough fish in the first place. Because there is a fear that fresh fish contains high levels of PCB's, dioxins, organochlorine pesticides and heavy metals, a carefully selected fish oil supplement may be a much better and also remove any concern you may have.
