Fish oil supplements exist to close a gap most diets have: omega-3 fatty acids (specifically EPA and DHA), which the body needs but doesn't produce in meaningful amounts on its own. Unless you're eating oily fish (salmon, mackerel, sardines) at least twice a week, a daily fish oil supplement is one of the more evidence-backed additions to a general health routine — well-established outside of sports nutrition specifically, not just gym marketing.
What EPA and DHA actually do
These two omega-3 fatty acids are linked to heart, brain, and joint health, and are also associated with helping manage exercise-induced inflammation — relevant if you're training regularly and dealing with recovery demands beyond what diet alone typically provides. A quality fish oil supplement should deliver 250–500mg of combined EPA and DHA per serving at minimum; higher-strength options in this category go further for those wanting a more concentrated dose.
What to look for on the label
Focus on the actual EPA/DHA content rather than total fish oil weight — a 1000mg softgel that's mostly filler oil delivers far less omega-3 than a well-formulated 1000mg capsule with a higher concentration. Products labelled "high strength" (like [Insight Omega High Strength]) typically indicate a more concentrated EPA/DHA ratio rather than just a bigger capsule.
Who this is for
- Anyone not eating oily fish at least twice a week
- Regular trainers wanting additional support for recovery and joint comfort
- Anyone building a foundational daily supplement stack alongside a multivitamin
How to use: typically 1–2 softgels daily with food — check the specific product for its EPA/DHA content per serving, since dosing varies meaningfully between brands.
Pair with our Joint Health range if joint comfort is a specific focus, or see Vitamins/Minerals for the rest of your daily foundational stack.
