Enter the body weight and recommended dosage per kg of body weight into the calculator to determine the daily dosage of fish oil.

Fish Oil Formula

The following formula is used to calculate the daily dosage of fish oil.

DD = (BW * R) / C

Variables:

  • DD is the daily dosage of fish oil (mg)
  • BW is the body weight (kg)
  • R is the recommended dosage per kg of body weight (mg/kg)
  • C is the concentration of EPA and DHA in the fish oil supplement (mg/ml)

To calculate the daily dosage of fish oil, multiply the body weight by the recommended dosage per kg of body weight. Then divide the result by the concentration of EPA and DHA in the fish oil supplement.

What is a Fish Oil?

Fish oil is a dietary supplement derived from the tissues of oily fish. It contains omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are known for their health benefits. These benefits include reducing inflammation, lowering blood pressure, improving heart health, and supporting mental health. Fish oil is often consumed in the form of capsules for convenience and dosage control.

How to Calculate Fish Oil?

The following steps outline how to calculate the Daily Dosage of Fish Oil.


  1. First, determine the body weight (BW) in kilograms (kg).
  2. Next, determine the recommended dosage per kg of body weight (R) in milligrams per kilogram (mg/kg).
  3. Next, determine the concentration of EPA and DHA in the fish oil supplement (C) in milligrams per milliliter (mg/ml).
  4. Next, gather the formula from above = DD = (BW * R) / C.
  5. Finally, calculate the Daily Dosage of Fish Oil.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

body weight (BW) = 70 kg

recommended dosage per kg of body weight (R) = 10 mg/kg

concentration of EPA and DHA in the fish oil supplement (C) = 500 mg/ml
