Omega-3, or n-3, fatty acids isafamily of polyunsaturated fats obtained from our diets. They are called essential fatty acids since they are required for health, though the body cannot synthesize them. The chemical structure of polyunsaturated fatty acids has several double bonds. For instance,omega-3 fatty acidshave the first double bond positioned three carbon atoms away from the omega end.
Omega-3 fatty acids are very vital for your health. Consuming whole foods rich in omega-3s, including fatty fish, is the best strategy to acquire them adequately.However, if you take fewer fatty fish, you mayneed to add various omega-3 supplements, including krill oil, fish oil, cod liver oil, and algal oil (a vegetarian source extracted from algae). These supplements offer a broad range of doses and forms of omega-3s. Due to insufficient information on omega-3 supplements, this article will discuss everything you should know about them.
Omega-3 Supplement Forms
Algal Oil
Marine algae, especially microalgae, are another triglyceride source of EPA and DHA. The DHA and EPA in fish originate from algae consumed by smaller fish moving up the food chain. Research shows that algal oil is even more concentrated in omega-3s, specifically DHA, than fish oil, making ita reliable source for vegans and vegetarians. It might also contain essential minerals like iodine. Furthermore, algal oil is environmentally friendly and doesn’t have any contaminants, such as heavy metals, which makes it a sustainable healthy option.
Mammalian Oil
Mammalian omega-3 oil is extracted from seal blubber asnatural triglycerides. Besides DHA and EPA, it also contains relatively high docosapentaenoic acid (DPA), an omega-3 fatty acid with many potential health benefits. Mammalian omega-3 oil is also exceptionally low in omega-6.
Krill Oil
Krill oil is extractedfrom Antarctic krill, a minute shrimp-like vertebrate. This oil has omega-3s in phospholipid and triglyceride forms. Several studies have concluded that omega-3 is absorbed perfectly from the phospholipid in krill oil and triglycerides in fish oil. However, krill oil is greatly opposed to oxidation since it normally has an effective antioxidant known as astaxanthin. Furthermore, krill are so minute and have a limited lifespan, so they don’t buildup numerous contaminants in their life before dying. Thus, krill oil does not need purification and is seldomfound in the ethyl ester form.
Natural Fish Oil
This oil is extracted from the tissues of oily fish, mainlyas triglycerides. Natural fish oil has multiplevital nutrients. The quantity of omega-3s in fish-includingDHA and EPA ranges from 18 to 31%, but the amount differs between fish species. Additionally, natural fish contains vitamins A and D. Sardines, menhaden, salmon, and cod liver are among the most dominant sources of normal fish. These oils are availed in liquid or capsules forms.
Green-Lipped Mussel Oil
This vertebrateis popular in New Zealand, and its oil is often free of fatty acids and triglycerides. Besides DHA and EPA, it also has trace amounts of eicosatetraenoic acid (ETA). This minimal omega-3 fatty acid may be more efficacious at reducing inflammation thanother omega-3s. Also, taking green-lipped mussel oil rather than fish oil is regardedas environmentally safe.
Processed Fish Oil
Processed fish oilconsists of ethyl esters or triglycerides. Purification removes impurities, including mercury and PCBs. Concentrating this oil can also elevate DHA and EPA levels. Most processed fishoils may consist of up to 50-90% pure DHA and EPA and occupy a significantfish oil market percentage sincethey are cheap and often available in capsules, popular with customers. The human body does not uptake processed fish oilas ethyl ester, which appears to be more susceptible to rancidity and oxidation than triglycerides.Therefore, some manufacturers further convert fish oil into synthetic triglycerides to maximize theiruptake. However, triglycerides are expensive fish oil supplements and occupya minute percentage in the market.
Omega-3 Capsules
Omega-3 capsules or softgelsare popular because they are taste-free and light to swallow. These capsules are frequently manufactured from a soft gelatin layer, while someproducers also use an enteric coating. Enteric coating assists inpreventing the capsule from dissolving until it reaches the small intestine. It is popular in fish as it inhibitsfish burps. Nonetheless, it can further cover the foul odor of rancid fish oil. Therefore, taking omega-3 capsules may expose you to smell and ensurethe fish oil hasn’t gone rancid.
Tips for Picking A Good Omega-3 Supplement
When purchasing an omega-3 supplement, ensure that you read the label. Other crucial things to check include:
The Omega-3 Quantity
A supplement might indicate on the fore that it consists of 1000mg of fish oil for every capsule, while on the rear, you will only see that DHA and EPA are just320mg.
Freshness
Omega-3s are vulnerable to becoming rancid, having a foul smell, or evenless effectiveandhazardous.When buying the supplement,confirm the date, feel the product’s smell and check if it has an antioxidant such asvitamin E.
Purity and Authenticity
Buy products that have either the GOED standard for purity or a third-party seal. These labels confirm that they are safe.
Sustainability
Purchase fish oil that the environmental Defense Fund or a similar organization and MSC has certified. Tiny fish with a short lifespan appears to be easier to sustain.
The Best Omega-3 Supplements Brands
A consistent fish oil supplement might be the best option for most folks looking to boost their health. However, know that normal fish oil comprises 30% EPA and DHA and 70% other fats. You can also purchase supplements that have a higher concentration of omega-3s. DHA and EPA have a maximum of 90%. For best outcomes, seek brands that sell omega-3s supplements without fatty acids, such as phospholipids and triglycerides. A few reputable omega-3 supplement brands include Green Pasture, Nordic Naturals, Omega Via, Bio-Marine, and Omega-3.
Conclusion
A regular oil supplement is probably enoughfor most folks.However, ensure that the supplement contains what it indicates on the label and check the DHA and EPA content. Vegetarian choices arealsoavailable, but they usually contain ALA. DHA and EPA are commonly found in animal-based omega-3 products. One exception is algal oil, a perfect source of quality omega-3s and suitable for everybody, including vegans. It isalsobest to eat these supplements with a meal that contains fat because they increase the absorption of omega-3s.Additionally, know that omega-3 supplementsare perishable, although they are the most beneficial; hence, you shouldchoose wisely.
