Computes how many servings of a fish oil supplement are needed to reach a target daily combined EPA+DHA (omega-3) intake, given the supplement's label EPA+DHA content per serving. A commonly cited general-population guidance range for combined EPA+DHA intake for general health is roughly 250-500 mg/day (e.g. as summarized by organizations such as GOED, the Global Organization for EPA and DHA Omega-3s, and various national dietary guidelines). This is a supplement-serving-size arithmetic tool, not medical dosing advice. Consult a doctor or registered dietitian for individualized omega-3 intake goals.
How it works
Enter the combined EPA+DHA content per serving (from the supplement label) and your target daily combined EPA+DHA intake. The tool divides the target by the per-serving amount to compute servings needed.
- Enter combined EPA+DHA per serving (mg, from the supplement label).
- Enter target daily combined EPA+DHA (mg).
- Click Calculate to see your results.
Examples
300 mg EPA+DHA per serving, target 500 mg/day
500 / 300 = 1.67 servings/day, rounded up to 2 servings for about 600 mg/day actual intake.
Who should use it
- Comparing different fish oil supplement products.
- General omega-3 intake planning.
Industry applications
- Nutrition and supplement education
- General wellness reference
Advantages
- Simple serving-size arithmetic.
- Cites a recognized general guidance range (GOED/dietary guidelines).
Limitations
- A serving-size calculation only, not personalized medical dosing advice.
Common mistakes to avoid
- Using total fish oil serving size (which includes other fats) instead of just the EPA+DHA content specifically.
Best practices
- Read the supplement facts label carefully — "1000mg fish oil" often contains much less than 1000mg of actual EPA+DHA.
Tips
- Some supplements express EPA and DHA separately on the label — remember to add them together before entering the per-serving value.
