Recommended dose: Represented values are for orientation purposes only.
If sourcing omega 3s through a fish diet, the American Heart Association recommends eating 2 portions of oily fish (7 ounces) a week.
Equivalent doses of supplement tablets/capsules must be taken every day.
The recommended doses may change depending on whether an individual suffers from a medical condition. If this is the case, following the advice of a medical practitioner is advised.
It is also advisable to consume omega 3 from different sources, meaning you should eat fish as your primary source of omega 3 fat, but you should also consume for example flaxseed oil from time to time to change the source of omega 3 fats. You can also buy two types of omega 3 rich oil and mix (consume) them together.
