Guide to Choose the Best Omega-3 Supplement

If you find that your diet lacks a sufficient intake of omega-3 fatty acids, particularly from sources like fatty fish, you might want to explore the option of omega-3 supplements. Omega-3 supplements come in various forms, ranging from conventional fish oil to mammalian oil.

Omega-3 fatty acids play a pivotal role in promoting overall health and well-being. While the most ideal way to secure an adequate supply of omega-3s is through the consumption of whole foods rich in these fatty acids, such as fatty fish, supplements can be a valuable alternative for those who don’t consume these foods regularly.

However, it’s important to acknowledge that the market offers a plethora of omega-3 supplements, each with its own unique set of health benefits and characteristics. To make an informed decision regarding which supplement suits your needs best, refer to our comprehensive guide at

Diverse Forms of Omega-3

Omega-3 supplements are available in several distinct forms, with each form presenting specific attributes that affect their absorption rates and health benefits. These forms encompass:

Natural Fish Oil:
Derived from the tissues of oily fish, natural fish oil is primarily found in the form of triglycerides, making it the closest equivalent to consuming fish in its natural state. It contains a spectrum of crucial nutrients and vitamins, including omega-3 fatty acids such as EPA and DHA, as well as vitamins A and D. Natural fish oil’s omega-3 content, comprising both EPA and DHA, typically ranges from 18% to 31%, with variability among different fish species.

Processed Fish Oil:
Processed fish oil undergoes purification and concentration processes, often leading to the conversion of fatty acids into either ethyl esters or triglycerides. Purification serves to eliminate contaminants like mercury and PCBs, while concentration can boost the levels of EPA and DHA, with some oils containing as much as 50% to 90% pure EPA and/or DHA. Processed fish oils constitute the majority of the fish oil market, given their cost-effectiveness and popularity in capsule form. However, it’s essential to note that the human body may not absorb processed fish oil in its ethyl-ester form as effectively as natural fish oil. Moreover, ethyl esters are more prone to oxidation and rancidity compared to triglycerides. Nonetheless, certain manufacturers further refine processed fish oil to convert it back into a synthetic triglyceride form, which is better absorbed. These oils are often referred to as “reformed” or “re-esterified” triglycerides, although they represent a smaller segment of the market.

Krill Oil:
Krill oil is extracted from Antarctic krill, small shrimp-like marine creatures. It contains omega-3 fatty acids in both triglyceride and phospholipid forms. Numerous studies have demonstrated that omega-3 absorption from phospholipids in krill oil can be as effective as, or even more effective than, absorption from triglycerides in fish oil. Krill oil boasts natural resistance to oxidation, courtesy of its abundant antioxidant, astaxanthin. Krill, being small and having a limited lifespan, accumulate fewer contaminants throughout their lives. Consequently, krill oil rarely requires purification and is seldom found in the ethyl ester form.

Green-Lipped Mussel Oil:
Native to New Zealand, the green-lipped mussel typically yields oil primarily in the form of triglycerides and free fatty acids. In addition to EPA and DHA, it contains trace amounts of eicosatetraenoic acid (ETA), a rare omega-3 fatty acid noted for its potential to reduce inflammation. Opting for green-lipped mussel oil over fish oil is often considered a more environmentally friendly choice.
