Do you have a preference on when you take your multivitamin and fish oil supplement? A frequently asked question we get in stores is: “Should I take my supplements together, or separately?”

The below information will help you decide if taking both a multivitamin and a fish oil supplement works for your current routine.


Consider a supplements purity when choosing a multivitamin and fish oil. Your multivitamin and fish oil supplement should come from a company that holds the quality of their product as a priority.

How do you know if your fish oil supplement is a quality one?

Formulas that contain the Omega-3 fatty acids EPA and DHA and have their potency clearly marked, is a sign of quality supplements. The fish oil should be purified to reduce heavy metals and other contaminants.

Should you take a multivitamin and fish oil supplement together?

Fish oil supplements are known to be naturally high in vitamins A and D. However, that’s not always the case. Most traditional fish oil supplements (from the oil in fish meat) do not contain significant amounts of vitamin A or D. Some oils from fish liver (such as cod liver oil) contain significant levels of vitamins A and D and may potentially result in exceeding the recommended daily intake if taken with a multivitamin.

It is important to read the supplement facts label, if you’re taking many supplements per day. Taking both a multivitamin and a fish oil supplement is not necessary, but together they can complement your diet. Taking a fish oil supplement and a multivitamin together should not be a concern. Always talk to your physician if you have specific questions about the right supplements for you.

Could you be missing key nutrients in your daily diet?

A multivitamin fills nutritional gaps for nutrients that you are not getting sufficiently from food. It is possible to meet your daily recommended intake through diet alone, but it can be hard to maintain a balanced diet every day, especially if you’re following a lower calorie diet. Plus, while a multivitamin with minerals can cover your basic vitamin and mineral needs, most do not provide a source of healthy fat. This is why a fish oil supplement is important. Combining a fish oil supplement with your daily multivitamin complements your overall nutritional diet.

If you’re still unsure if you need both multivitamins and fish oils, answer the below questions. If you answered “no” to one or more of the following questions, you might be missing key nutrients in your diet. If that’s the case, taking a multivitamin and a fish oil supplement might support your nutritional needs.

Do you eat 7-10 servings of fruits and vegetables a day?
Do you consume at least 2-3 servings of dairy products a day?
Do you eat the recommended 2 servings of fish per week?
