Why might you need multiple servings of fish oil to reach 3 grams of EPA and DHA?

• A. Because all brands have the same concentration but you must take more.
• B. Because EPA and DHA are not absorbed well.
• C. Because different brands have different EPA and DHA concentrations, and some include other omega-3s.
• D. Because fish oil does not contain EPA or DHA.

Answer: (C)

The key idea is that EPA and DHA content varies by product. Each serving of fish oil lists a specific amount of EPA plus DHA (measured in milligrams), but different brands and formulations have different concentrations. Some capsules may also include other omega-3s or fatty acids, so not every serving contributes the same amount of EPA and DHA.

To reach 3,000 mg of EPA+DHA, you need to look at the label, add up the total EPA+DHA per serving, and calculate how many servings are required. For example, if a capsule provides 600 mg of EPA+DHA, you’d need five servings; if another product provides 1,000 mg per capsule, three servings would meet the goal. That variability is why multiple servings might be needed.

Absorption isn’t the issue; EPA and DHA are absorbed when consumed. Also, fish oil products do contain EPA and DHA, so the reason you might take more than one serving is simply the differing concentrations across brands and formulations.
