What does it do?
Omega-3 is a family of fatty acids. ALA must come from food. The body can convert it to EPA and DHA, but only to a limited extent. DHA is part of cell membranes, especially in the brain and retina. This does not establish performance benefits from extra capsules.
Where can you find it?
Rapeseed oil, linseed oil and walnuts provide ALA. Oily fish such as salmon supplies EPA and DHA. These sources are not interchangeable one for one.
Make it work in everyday life
Start with your usual ingredients: which oil do you use, and does your family eat fish? A familiar meal can often be varied with one suitable ingredient. Avoiding fish calls for thoughtful planning, not a self-designed high-dose regimen. Offer nuts in a form suitable for younger children; texture needs to match safe chewing skills.
Is a walnut dish equivalent to a fish dish?
No. It mainly provides a different omega-3 form. These ingredients can fit different diets without guaranteeing the same EPA and DHA content.
