Short answer

We found no documented interaction between Zinc and Omega-3 in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

Zinc

What it is: An essential mineral for the immune system, wound healing, taste, and making DNA and proteins.

What the research says: Zinc is needed for normal immune function; it's commonly taken to make sure intake is adequate.

Cautions

• Adults shouldn't exceed 40 mg a day from all sources unless under medical care.
• Too much for a long time can lower copper levels and immunity.
• Very high doses can reduce magnesium absorption.

Medicines to check

• Quinolone and tetracycline antibiotics: take the antibiotic at least 2 hours before or 4 to 6 hours after zinc
• Penicillamine: take at least 1 hour apart
• Thiazide diuretics can lower zinc levels

Omega-3 (fish oil)

What it is: Fats (EPA and DHA) found in fish that are part of every cell membrane and matter for the heart, brain and eyes.

What the research says: EPA and DHA lower triglycerides. Heart experts recommend eating fish; they don't recommend omega-3 supplements for people at low heart risk.

Cautions

• The FDA advises no more than 5 g a day of EPA plus DHA from supplements.
• Side effects are usually mild: fishy taste, heartburn, nausea, loose stools.

Medicines to check

• Warfarin and other blood thinners: high doses may raise bleeding risk
