BiOmega: EPA, DHA, and vitamin D per serving

Joy Health transcribed every row below and checked it against the U.S. label USANA publishes.^[1] Amounts, units, and % Daily Values are exactly as printed. Formulas change, so compare the label on your own package.

Directions on the label: Take two (2) capsules daily, preferably with food.

Other ingredients: Fish Gelatin, Glycerin, Lemon Oil, Purified Water, Mixed Natural Tocopherols.

Contains: Fish (anchovy, mackerel, sardine, tilapia)

EPA and DHA are listed inside the total omega-3 amount. Together they make up 1,100 mg of the 1,200 mg; the label does not name the other 100 mg. The fish behind the oil are named in the allergen line: anchovy, mackerel, sardine, and tilapia.^[1]

At two capsules a day, vitamin D is the only BiOmega ingredient with an adult Tolerable Upper Intake Level (UL), and 5 µg is small next to the 100 µg limit. It does add to the vitamin D in the other products below, and NIH notes that vitamin D toxicity almost always comes from supplements.^[5] Fish oil has no UL. FDA has concluded that supplements providing no more than 5 g of EPA and DHA a day, used as labeled, are safe and lawful; two capsules provide 1.1 g.^[4]

Daily amounts multiply the label's per-serving amounts by the servings its directions call for. Food, drinks, fortified foods, and other supplements add to these totals. A Tolerable Upper Intake Level (UL) is the highest daily intake likely to pose no risk of adverse effects for almost all healthy people in an age group. It is not a recommended intake.^[9]

Yes. BiOmega is certified to NSF/ANSI 173: NSF's official listing for USANA's Salt Lake City facility names “OPTIMIZERS™, BiOmega™” under NSF/ANSI 173, the dietary supplement standard, with a recommended daily serving of 2 gelcaps.^[2] NIH describes this kind of third-party certification as independent assurance that a product contains the labeled amounts of its ingredients.^[6]

Joy Health interpretation: the listing answers a quality question about this product. It does not show that fish oil will do a particular thing for a particular person; the supplement evidence guide explains how to match a claim to evidence.

• Fish allergy. The label says it contains fish: anchovy, mackerel, sardine, and tilapia.^[1]
• Blood thinners. NIH notes that fish oil might prolong clotting times when taken with warfarin, though most research finds that 3 to 6 g of fish oil a day does not significantly change anticoagulant status.^[3]
• Heart rhythm. Two large trials found that 4 g a day of prescription omega-3 products slightly raised the risk of atrial fibrillation in people with or at high risk of heart disease.^[3] Those trials used different products at several times this dose, so ask a clinician if you have a heart rhythm condition rather than assuming either way.
• Surgery. FDA notes that a clinician may ask you to stop supplements two or three weeks before a procedure, in part because of bleeding risk.^[7]
• Vitamin D from several products. Add BiOmega's 5 µg to any other vitamin D you take; the table above shows the amounts in the other products on this site.

FDA does not approve dietary supplements before they are sold, and it advises talking with a doctor, pharmacist, or other health professional before using one, because some supplements interact with medicines or other supplements.^[8]
