The Blends and Key Ingredients

These are the ingredients used in Onnit Krill Oil


Astaxanthin, which can be found in krill oil, is a potent free radical scavenger, providing antioxidant and anti-inflammatory properties.

Astaxanthin has been the subject of many studies for its potential use in cancer treatment due to its antioxidant characteristics. The development of breast cancer cells was slowed in one research, among other benefits for treating the disease.

Astaxanthin has been shown to improve immunological function and can have anti-inflammatory effects. In particular, this pigment inhibits proteins that contribute to inflammatory disorders, including celiac, rheumatoid arthritis, heart disease, and diabetes, by acting on reactive oxygen species.

Moreover, krill oil’s astaxanthin content makes it useful for extending both the longevity of stored products and quality over time.

Omega 3 Fatty Acids

These fats are essential and can be obtained from meals like fish or nutritional supplements because the human body does not make them. They aid in cardiovascular health and provide neuroprotection in the brain. Additionally, they can improve one’s mood and mental capacity.

Additionally, they are rich in antioxidants, which reduce inflammation and discomfort in the joints. The medical journal CMAJ released a paper that delved into the research on omega-3 fats.

Krill Oil

This lipid oil’s high levels of the omega-3 fatty acids EPA and DHA are beneficial to mental and cardiovascular health. It is derived from sea crustaceans and is more effective and nutritious than fish oil. In addition, it has a high concentration of antioxidants, which boost immunity and aid in the body’s natural healing processes.

Research has shown that omega-3 fatty acids, like those present in krill oil, play a key role in reducing inflammation throughout the body.


These lipids, made up of fatty acids, play an essential role in the structure of cell membranes, particularly those of the brain. They aid and encourage cellular activity.

Furthermore, they include a lot of antioxidants, which are good for your health and your immune system. In a recent study published in Molecular Cellular Biochemistry, researchers examined the function of phospholipids in the central nervous system, cardiovascular system, renal system, and hepatic cells.
