The Best Omega-3 Supplements: 2024 Buyer's Guide

 Omega 3 fatty acids (omega-3s) are polyunsaturated fatty acids (PUFAs) with various bodily functions. The three main omega-3s are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The ALA is found predominantly in plant-based sources, while EPA and DHA are found in animal foods, particularly seafood.

A healthy and balanced diet is enough to meet the daily requirement of 1.1-1.6g, as the National Institute of Health (NIH) suggests. However, people with limited dietary intake, those following a vegan diet plan, or those having inflammatory, cardiovascular, and depressive disorders must consider supplementation.

How to select the best supplement? What do you need to know before choosing a supplement? This review explains everything you need to know about omega-3 fatty acids and the best products in the 2024 market.

Different forms of Omega-3 fatty acids  

The Omega-3 fatty acids are available in four forms in natural sources and supplements. These are free fatty acids, triglycerides, ethyl esters, and phospholipids. These types differ in digestion and absorption. 

Free fatty acids (FFAs)

Free fatty acids are not bound to other molecules, e.g., glycerol in triglycerides. They are rapidly absorbed as they are already digested and in their simplest form. Most of the omega-3 fatty acids supplements contain EPA and DHA.

Triglycerides and phospholipids 

These are complex fatty molecules in which omega-3s are bound to other molecules. They release fatty acids after digestion. They are present in whole fish and fish oil and have slower absorption than FFAs. 

Ethyl esters

The fatty acids are converted into ethyl esters in concentrated fish oil supplements. This form requires enzymatic digestion before absorption and has a lower absorption rate than the other types.

Key Considerations When Choosing a Supplement

Before choosing an omega-three supplement, check the product label for the following things. 

Type of Omega-3s present: DHA and EPA are the most important forms of omega-3 fatty acids. Make sure the chosen product has these nutrients. 

Amounts/ doses of omega 3s: Read the amounts carefully and check how many mgs of EPA and DHA they offer. For example, a supplement containing 1000mg of fish oil will have only around 300 mg of EPA and DHA. 

Different forms of omega-3 fatty acids: Different types of omega-3 fatty acids are free fatty acids, triglycerides, reformed triglycerides, phospholipids, and ethyl esters. Free fatty acids have the highest absorption, while ethyl esters have the slowest absorption. Having a more absorbable form is preferred. 

Authenticity and purity: Check the labels on the products about testing, particularly third-party testing. For example, The Global Organization for EPA and DHA Omega-3s (GOED) certification is the accepted standard for purity and quality. 

Expiry date: All fats, including omega-3s, are prone to spoilage when stored for a long time. They produce a putrid odour and become rancid. The rancid fats are less helpful and even harmful to health. It is recommended to check the expiry date and smell it to detect the putrid odour. 

Presence of other ingredients: Some products contain other valuable ingredients, e.g., vitamin E, vitamin D, etc. A product containing these ingredients has additional benefits. However, ensure that these nutrients don't come at the cost of low doses of omega-3 fatty acids. 

Eco-friendliness: Buy an environment-friendly product certified by organisations like the Environmental Defence Fund (EDF).

Frequently Asked Questions 

Which supplement is the best to get essential omega-3 fatty acids? 

The ‘best supplement’ choice is subjective, and many individual factors are considered. The best products in our ranking are Day Lewis Omega 3 Fish Oil, Lamberts Omega 3 Ultra Pure Fish Oil and SeaRich Omega-3.

Which is better? EPA or DHA? 

Both forms are suitable. However, studies have noted that DHA has more potent anti-inflammatory properties than the EPA. 

How much omega-3 fatty acids should be taken daily? 

The recommendation varies from person to person. The National Institute of Health (NIH) recommends regularly taking 1.1-1.6g of omega-3 fatty acids. 

What are the top natural sources of omega-3 fatty acids? 

According to research, the top natural sources of omega-3 fatty acids are Sardines (2g EPA and DHA/3-ounce serving), Atlantic Salmon (2.4g of EPA and DHA/6-ounce serving), Herring (1.5g of EPA and DHA/3-ounce serving), chia seeds (5g ALA/1-ounce serving) and flaxseed (1.8g ALA/ tablespoon). 

Which oil is the richest source of omega-3 fatty acids? 

Fish oil, canola oils, soybean and flaxseed are the richest sources of omega-3 fatty acids. 

What are the side effects of Omega 3 fatty acids supplementation? 

The side effects are mild and rare. Some users experience headaches, eructation, vomiting, abdominal distension, foul-smelling breath, poor taste and gastrointestinal symptoms like diarrhoea, diarrhoea, and heartburn. 

Do eggs contain Omega-3 fatty acids? 

Yes, eggs are a decent source of omega-3 fatty acids. Each serving of two eggs provides 180mg of omega-3 fatty acids. 

Which foods are a good source of omega-3 fatty acids? 

Some omega-3 fatty acids-rich fruits are oranges, berries, avocado, papaya, seeds and nuts, fish and other seafood, kiwifruit and plant oils, e.g., canola oil, soybean oil and flaxseed oil. However, one must not rely on the fruits as a sole source. 

What are the symptoms of omega-3 fatty acids deficiency? 

A deficiency of omega-3 fatty acids causes symptoms like troubled sleep, fatigue, poor nails, hair and skin health, leg cramps, joint pain, poor concentration, cardiovascular concerns and menstrual irregularities.

Conclusion 

Choosing supplements with higher EPA and DHA contents is beneficial as these are the most effective forms of omega-3 fatty acids from animal sources. Some vegan products that contain ALA are available. Regardless of the choice, taking these supplements with fatty meals is necessary, as fat increases the absorption of omega 3s. 

Like other fats, omega 3s are prone to spoilage over time, and choosing a long supply for months and years is not a good idea. Before going for supplementation, testing the levels of different fatty acids in the blood is critical. Welzo offers Omega 3 and 6 (Essential Fatty Acids) Blood Test for this purpose.
