NOW Foods Krill Oil 500 mg
Discover a superior source of essential fatty acids with NOW Foods Krill Oil. This premium supplement delivers 500 mg of Neptune Krill Oil (NKO®) in each softgel, providing a potent blend of Omega-3s in a highly bioavailable form. Uniquely bound to phospholipids, the EPA and DHA in krill oil are readily absorbed by the body to support joint comfort, heart health, and healthy brain function. With the added benefit of naturally occurring Astaxanthin and enteric-coated softgels to prevent fishy aftertaste, NOW Krill Oil is the intelligent choice for your daily wellness.
What is Krill Oil?
Krill oil is a nutrient-rich extract derived from krill, tiny shrimp-like crustaceans that inhabit the cold, pristine waters of the Antarctic. What makes krill oil exceptional is its unique molecular structure. Unlike fish oil, where the Omega-3 fatty acids EPA and DHA are bound to triglycerides, the Omega-3s in krill oil are attached to phospholipids. This phospholipid structure is the same as that of human cell membranes, allowing the body to absorb and utilize these vital fats with remarkable efficiency. Furthermore, krill oil is a natural source of Astaxanthin, a potent carotenoid antioxidant that gives krill its characteristic red color and helps to protect the fragile Omega-3s from oxidation.
Why Choose NOW Krill Oil?
Superior Bioavailability and Absorption
The primary advantage of NOW Krill Oil lies in its phospholipid-bound Omega-3s. Because your body’s cells are also surrounded by phospholipid membranes, they can easily recognize and incorporate the EPA and DHA from krill oil. This superior bioavailability means that more of the beneficial fatty acids get delivered directly to where they are needed most—your brain, heart, and joints. A scientific review published on PubMed Central highlights that the phospholipid form may lead to more efficient incorporation of Omega-3s into tissues compared to the triglyceride form found in fish oil.
Potent Antioxidant Protection with Astaxanthin
Each softgel of NOW Krill Oil contains naturally occurring Astaxanthin, a powerful antioxidant that helps combat oxidative stress at the cellular level. This potent carotenoid not only provides its own health benefits but also acts as a natural preservative, protecting the delicate EPA and DHA fatty acids from degradation. This ensures that the oil remains fresh and potent from the time it’s encapsulated until you consume it, maximizing its effectiveness.
Comprehensive Support for Joint, Brain, and Heart Health
The balanced profile of nutrients in NOW Krill Oil offers multi-system support. Its anti-inflammatory properties are excellent for promoting joint comfort, flexibility, and mobility. For cognitive health, the high concentration of DHA is crucial for maintaining brain function, memory, and mood. Furthermore, the combination of EPA and DHA is well-known for its role in supporting cardiovascular health by helping to maintain healthy cholesterol and triglyceride levels already within the normal range.
Enteric-Coated for No Fishy Burps
One of the most common complaints about Omega-3 supplements is the unpleasant fishy aftertaste or “fishy burps.” NOW Foods has solved this problem by using special enteric-coated softgels. This coating allows the softgel to survive the acidic environment of the stomach and dissolve in the more alkaline small intestine. This ensures optimal absorption of the krill oil and completely eliminates the possibility of fishy reflux, making your daily supplement routine a much more pleasant experience.

Frequently Asked Questions
What is the main difference between krill oil and fish oil?
The key difference is in their structure and composition. Krill oil’s Omega-3s are bound to phospholipids, making them more easily absorbed by the body than the triglyceride-bound Omega-3s in fish oil. Krill oil also naturally contains the antioxidant Astaxanthin, which is not found in most fish oils, and it is sourced from a more sustainable biomass.
Why is this krill oil red?
The red color comes from Astaxanthin, a natural carotenoid pigment found in the microalgae that krill feed on. This powerful antioxidant is responsible for the red-pink hue of krill, shrimp, and salmon.
What does it mean that this product is “enteric-coated”?
Enteric coating is a special layer on the softgel that prevents it from dissolving in the stomach. Instead, it dissolves in the small intestine. This has two major benefits: it prevents the fishy aftertaste and burps common with Omega-3 supplements, and it ensures the oil is released where it can be best absorbed.
Can I take krill oil if I have a shellfish allergy?
No. Krill are crustaceans, which are a type of shellfish. Individuals with an allergy to shellfish (such as shrimp, crab, or lobster) should not use this product. It is crucial to consult your doctor if you have any food allergies before taking a new supplement.
Is the krill in this supplement sustainably sourced?
Yes. NOW Foods uses Neptune Krill Oil (NKO®), which is known for its sustainable and responsible harvesting practices. The krill are harvested in the pristine Antarctic Ocean in a manner that is carefully managed to ensure the stability of the krill population and the surrounding ecosystem.
