Omega-3 EPA/DHA

Yes. Omega-3 supplements such as fish oil can interact with warfarin (Coumadin) and similar anticoagulants, with fish oil having antiplatelet effects at high doses and potentially prolonging clotting times. Most research indicates 3-6 g/day fish oil does not significantly affect the anticoagulant status of patients taking warfarin, but INR should be monitored periodically. — per the NIH Office of Dietary Supplements; general information, not medical advice.

Anything below the median is a solid deal for the same molecule.

Aim for about 1–3 g/day of combined — read the label and add the two, since a '1,000 mg fish oil' may hold only ~300 mg. Higher doses lower triglycerides but should be supervised. Take with a fatty meal.

The fact sheet notes that when the IOM last reviewed omega-3s it established Adequate Intakes rather than a (UL), so no UL is stated. The FDA specifies that the labels of dietary supplements should not recommend a daily intake of higher than 2 g — per the NIH Office of Dietary Supplements.

A deficiency of essential fatty acids — either omega-3s or omega-6s — can cause rough, scaly skin and dermatitis, and plasma and tissue concentrations of decrease when an omega-3 deficiency is present. However, classical essential fatty acid deficiency in healthy individuals in the United States is virtually nonexistent; clinical signs are usually only found in patients receiving parenteral nutrition that lacks polyunsaturated fatty acids — per the NIH Office of Dietary Supplements.

Plant oils that contain ALA include flaxseed (linseed), soybean, and canola oils, and chia seeds and walnuts also contain ALA. Cold-water fatty fish, such as salmon, mackerel, tuna, herring, and sardines, contain high amounts of long-chain omega-3s (), whereas lower-fat fish such as bass, tilapia, and cod, as well as shellfish, contain lower levels — per the NIH Office of Dietary Supplements.
