The makers of Neptune Krill Oil claim that its product, krill oil -- made from tiny crustaceans -- contains the highest levels of omega-3 fatty acids and antioxidants. Coenzyme Q10, or CoQ10, is an antioxidant produced by your body that keeps your cells healthy. In many cases, mixing supplements may cause negative side effects, but there are no indications that taking Neptune Krill Oil with CoQ10 is harmful. However, discuss taking them together with your doctor before adding them to your supplement routine.

Neptune Krill Oil

The creators of Neptune Krill Oil claim that it benefits heart and joint health as well as supports cognition and controls symptoms of premenstrual syndrome in women. The oil contains omega-3s and antioxidants, nutrients that protect many aspects of your health. The product contains a mix of fatty acids and antioxidants without any added ingredients. It's likely safe to take with CoQ10, which is another kind of antioxidant.


CoQ10 production decreases with age and some doctors recommend adding supplements to keep levels healthy. Certain health conditions might also play a role in decreased CoQ10 levels. The Mayo Clinic website reports few serious side effects from the use of CoQ10, which makes it safe for most people who are also using Neptune Krill Oil.

Taking Together

In general, mixing Neptune Krill Oil and CoQ10 isn't contraindicated by manufacturers of either product. However, this doesn't ensure the safety of combining the two. Talk with your doctor about adding Neptune Krill Oil and CoQ10 to your supplement regime, particularly if you have health conditions, which may make it unsafe. For example, according to New York University's Langone Medical Center, krill oil has been shown to lower blood sugar levels. CoQ10 may also produce decreased blood sugar levels, according to If you're diabetic or hypoglycemic, combining CoQ10 and Neptune Krill Oil may be dangerous. In addition, both supplements have an effect on blood-thinning and may not be safe if you're on medication for the condition, either alone or together.

Reading Labels

Neptune Krill Oil doesn't contain CoQ10, so it's unlikely that you will get too much of either by combining the two. However, there are many brands and types of CoQ10 on the market that contain other nutrients and supplements. Read the labels to ensure that the one you choose doesn't contain krill oil. If so, you may be getting more than the recommended .5 to 2 grams per day, the dosage recommended by the manufacturers of Neptune Krill Oil.
