Here’s the quick scoop for 115 g of King Oscar skinless, boneless mackerel in olive oil : it appears to provide about 5,040 mg of omega-3s total based on the brand’s stated 3,500 mg per 80 g serving , which scales to 115 g.

EPA and DHA

The sources I found do not break out EPA and DHA separately for this product, so I can’t give an exact EPA-vs-DHA split from the available label data.

What the label-style sources do support is the total omega-3 amount, not the individual fatty acids.

Other nutrients

For a drained 80 g serving, King Oscar mackerel is listed at about 240 calories, 16 g protein, 19 g fat, 0 g carbs, 350 mg sodium, 35 mg cholesterol, and 4 g saturated fat.

It also contains vitamin D, calcium, iron, and potassium in smaller amounts, and the ingredients are simply mackerel, olive oil, and salt.

Rough scaling to 115 g

If you scale the 80 g label to 115 g, the approximate values are:

  • Calories: about 345.
  • Protein: about 23 g.
  • Fat: about 27 g.
  • Sodium: about 504 mg.
  • Omega-3s: about 5,040 mg total.

Practical note

So the safest answer is: about 5.0 g of omega-3s total in 115 g , but the exact EPA and DHA amounts are not listed separately in the sources I found.

If you need, I can also estimate EPA and DHA from typical mackerel composition ranges.
