Fish Oil 3000mg: How to Find the EPA and DHA on the Label

Fish oil 3000mg on a label is the weight of oil in one labeled serving, which can be two or three softgels. It is not the amount of omega-3s. To know how much EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) a serving declares, find those two lines on the Supplement Facts panel and add them. The NIH Office of Dietary Supplements (ODS) says a typical fish oil supplement provides about 1,000 mg of fish oil containing 180 mg EPA and 120 mg DHA, but that doses vary widely. [1] Among the labels compared below, two servings that each declare 3,000 mg of oil list 477 mg and 1,500 mg of EPA plus DHA. [2] [3] Federal rules require the weight shown for an ingredient such as fish oil to be the weight of that ingredient, not of any component of it, and allow components such as EPA and DHA to be listed indented beneath it with their own weights. [4]

This page is general education about reading labels. It does not recommend any product or amount. If you take medicines, have a health condition, are pregnant or breastfeeding, or are considering a fish-oil product for a child, talk with your doctor or pharmacist first. [5] Two of the labels below carry similar cautions. [6] [7]

Safety first: if you take warfarin or another blood thinner, are allergic to fish or shellfish, or have atrial fibrillation (an irregular heart rhythm), ask your doctor before using any fish-oil product. ODS says high doses of omega-3s may cause bleeding problems when taken with warfarin or other anticoagulant medicines. [5] Prescription omega-3 labeling advises caution for people with a known fish or shellfish allergy and reports a possible link to more frequent episodes of atrial fibrillation in people who already have it. [8]

Five fish oil labels compared

Method. The table uses five fish-oil records from the NIH Dietary Supplement Label Database (DSLD), which captures the information printed on supplement labels sold in the United States, including products that are no longer sold, and identifies each by its DSLD record number. [9] A record shows what a label declares, not what a product has been tested to contain, so check any entry against the label you have. The per-softgel and percentage figures are our calculations from each label’s declared amounts.

3,000 mg can be several softgels. Labels A and B both declare 3,000 mg of oil per serving, but A’s serving is two softgels and B’s is three, so each softgel holds about 1,500 mg or 1,000 mg of oil (our calculation). [2] [3] Label C’s 3,600 mg figure is also for three softgels. [6] FDA says one serving of a dietary supplement is the maximum amount the label recommends per eating occasion, or one unit when the label gives no recommendation. [11]

Same oil weight, different EPA and DHA. Labels A and B each declare 3,000 mg of oil, yet B lists more than three times as much EPA plus DHA: 1,500 mg against 477 mg. [2] [3] Across the five labels, EPA plus DHA ranges from about 16% to 80% of the declared oil weight. [2] [7] A higher percentage describes how concentrated the oil is. It does not show that a product works better or suits you.

“Total omegas” is not the same as omega-3. Label A’s statement pairs “3000 mg” with “1400 mg total omegas”, while its panel lists 627 mg of omega-3 fatty acids. The panel also lists omega-5, omega-6, omega-7 and omega-9 fatty acids, and together with the omega-3s they come to about 1,409 mg (our calculation). [2] Check which fatty acids a “total” includes before comparing it with another label.

Total omega-3 can include more than EPA and DHA. Label B lists 1,860 mg of total omega-3 fatty acids, including 90 mg of docosapentaenoic acid (DPA), alongside its 1,500 mg of EPA plus DHA; label E lists 1,055 mg of total omega-3s and 1,000 mg of EPA plus DHA. [3] [7] ODS says omega-3 supplement formulations vary widely, so it is important to check labels for the types and amounts of omega-3s. [1] Label B’s record was entered in 2014, so the label in circulation may differ.

Why no %DV appears. FDA calls dietary ingredients without a Daily Value “other dietary ingredients”: they are listed by weight per serving, with a symbol pointing to the footnote “Daily Value Not Established”. [11] Each label above marks its oil line this way. [2] [3] [6] [7] [10] ODS notes that recommended amounts of EPA and DHA have not been established. [5]

How to read a fish oil label

• Serving size. Every amount on the panel applies to the labeled serving, which may be more than one softgel. [11]
• Oil line. A line such as “fish oil”, “fish body oil”, “salmon oil” or “fish oil concentrate” gives the weight of the oil itself per serving, not the weight of its omega-3s. [4] [2] [10] [7]
• EPA and DHA lines. These are constituents of the oil, listed indented under it, each with its own weight per serving. [4] [11] ODS describes EPA and DHA as long-chain omega-3s. [1]
• Total omega-3 or total omegas. A total may include DPA and other omega-3s, or, as on label A, other omega fatty acids too. [2] [3]
• Proprietary blends. For a proprietary blend, the rules require the total weight of the blend’s other dietary ingredients, listed in descending order, rather than each one’s amount. [4] If EPA and DHA appear only inside a blend, ask the manufacturer how much of each a serving provides.
• Form names. ODS lists natural triglycerides, free fatty acids, ethyl esters, re-esterified triglycerides and phospholipids among the forms in supplements. [1] Whatever the form, the figures to add up are the EPA and DHA weights the label declares.
• Calories and fat. Labels A, C, D and E also list calories, total fat and cholesterol per serving. [2] [6] [10] [7] FDA requires these on a Supplement Facts panel when they are present in measurable amounts. [11] For practice reading serving sizes on Nutrition Facts panels, see the food label reading worksheet.
• Capsule shell. All five labels list gelatin among their other ingredients. [2] [3] [6] [10] [7] The guide to a plant based vitamin B complex explains how to read capsule ingredients on a label.

Prescription omega-3 is a different product

A prescription omega-3-acid ethyl esters label on DailyMed states that each 1-gram capsule contains at least 900 mg of omega-3 ethyl esters, mainly about 465 mg EPA and about 375 mg DHA. [8] It is a medicine approved for a specific diagnosed condition and used under a prescriber’s care, and its labeling says people who take it with an anticoagulant or another medicine that affects clotting should be monitored periodically. [8] Do not swap a supplement for a prescribed omega-3 medicine, or the reverse, without your prescriber. DailyMed posts labeling that companies submit to FDA; NLM does not review it before publication. [12]

Adding up EPA and DHA

The U.S. Food and Drug Administration recommends consuming no more than 5 g a day of EPA and DHA combined from dietary supplements. [5] That ceiling is about EPA plus DHA, not fish-oil weight, it counts every supplement together, and it is not a recommended amount. The Institute of Medicine did not set an upper limit for omega-3s, but noted that high doses of EPA and DHA (900 mg a day of EPA plus 600 mg a day of DHA or more for several weeks) might reduce immune function, and that 2 to 15 g a day might increase bleeding time. [1] Two large clinical trials found that taking 4 g a day of omega-3 supplements for several years slightly increased the risk of atrial fibrillation in people with cardiovascular disease or at high risk of it. [1]

Hypothetical example. Suppose someone used one labeled serving of label C and one of label E on the same day. Together, those two labels declare 2,160 mg + 1,000 mg = 3,160 mg of EPA plus DHA, before counting a multivitamin with omega-3s, a cod liver oil or any other product. [6] [7] ODS notes that cod liver oil supplements also provide vitamin A and vitamin D. [1] Bring the whole list to your pharmacist or doctor rather than comparing it with a ceiling yourself.

Ingredient-label checklist for fish oil

Use these steps with each physical label in front of you, and write down the date you checked.

• Find the serving size. Note how many softgels, capsules or millilitres make up one serving. [11]
• Read the oil weight with its serving. A front figure such as 3000 mg may cover the whole serving. Divide by the number of softgels if you want the oil per softgel. [2] [3]
• Add EPA and DHA. Find the two lines indented under the oil and add their milligrams; that sum, not the oil weight, is what FDA’s supplement ceiling refers to. [4] [5]
• Check what any total includes. “Total omega-3” may include DPA, and “total omegas” may include omega-6, omega-7 and omega-9 fatty acids. [2] [3]
• Work out the concentration. Divide EPA plus DHA by the oil weight and multiply by 100. On the labels above this ranged from about 16% to 80%. [2] [7]
• Look for a proprietary blend. If EPA and DHA have no separate amounts, ask the manufacturer. [4]
• Read the allergen statement. Each label above declares fish, and several name the species. [2] [3] [6] [10] [7] If you have a fish or shellfish allergy, ask your doctor first. [8]
• Add up every product. List each product with EPA or DHA, including multivitamins and cod liver oil, with the servings you actually use. [1] [5]
• Bring the totals to your pharmacist or doctor. Mention any blood thinner or other medicine that affects clotting, and any history of atrial fibrillation. [5] [8]
• Match the record to your container. DSLD includes labels for products no longer sold, so compare any entry with the label you have. [9]

Safety notes

• ODS says side effects of omega-3 supplements are usually mild: an unpleasant taste in the mouth, bad breath, heartburn, nausea, stomach discomfort, diarrhea, headache and smelly sweat. [5]
• High doses of omega-3s may cause bleeding problems with warfarin or other anticoagulant medicines. [5] Prescription omega-3 labeling says omega-3 acids may prolong bleeding time. [8]
• Prescription omega-3 labeling says it is not known whether people with fish or shellfish allergies are at increased risk of an allergic reaction, and advises caution. [8]
• If you have atrial fibrillation, ask your doctor before using any omega-3 product. [1] [8]
• Talk with your health care provider about possible interactions between omega-3 supplements and your medicines. [5]

Where to go next

Whether you need fish oil, and how much EPA and DHA, is a question for your doctor or pharmacist. More label guides are listed under Ingredients and labels.

Common questions

Does fish oil 3000mg mean 3,000 mg of omega-3s?

No. It is the weight of the oil in one labeled serving. Two labels above that each declare 3,000 mg of oil list 477 mg and 1,500 mg of EPA plus DHA. [2] [3] [4]

How many softgels make 3,000 mg of fish oil?

It depends on the label. Label A reaches 3,000 mg in two softgels and label B in three. [2] [3] The serving size on the panel tells you. [11]

What is the difference between EPA, DHA and total omega-3?

EPA and DHA are two long-chain omega-3s. [1] A total omega-3 figure can also include others such as DPA, so it can be larger than EPA plus DHA. [3] [7]

Is a more concentrated fish oil better?

Not as a rule. Concentration only tells you how much of the oil is EPA and DHA; on the labels above it ranged from about 16% to 80%. [2] [7] Recommended amounts of EPA and DHA have not been established, so ask your doctor or pharmacist whether any amount suits you. [5]

Why does fish oil have no %DV?

Fish oil, EPA and DHA have no Daily Value, so FDA’s labeling guide has them listed by weight with the footnote “Daily Value Not Established”. [11]

If you take warfarin or another blood thinner, are allergic to fish or shellfish, or have atrial fibrillation, ask your doctor before using any fish-oil product. [5] [8]
