Buying Guide: What to Look for in Omega-3 Fish Oil
1. Triglyceride (TG) vs. Re-Esterified Triglyceride (rTG): The Absorption Factor
The form of omega-3 in your supplement matters more than you might think. Natural fish oil exists as triglycerides (TG), which your body recognizes and absorbs easily. Many cheaper supplements convert that oil into ethyl esters (EE) to concentrate EPA and DHA, but that form isn’t as bioavailable.
Re-esterified triglycerides (rTG) are created when ethyl esters are converted back into a triglyceride structure. Studies suggest rTG is absorbed up to 70% better than EE, and some research shows it may be slightly superior to natural TG. However, the difference between TG and rTG is often small when taken with food. For most people, both are excellent choices, as long as you avoid the ethyl ester form.

2. EPA and DHA Potency: More Isn’t Always Better
Look at the total EPA and DHA content, not just the total fish oil. For example, the Intelligent Labs product provides 1224mg EPA and 816mg DHA per serving, while the Built by Nature offers 700mg EPA and 350mg DHA. Higher potency means fewer pills to swallow, but it can also increase the risk of fishy burps.
Consider your dietary needs. If you eat fatty fish regularly, a lower dose may suffice. If you’re using fish oil to address specific concerns like joint pain or high triglycerides, a higher dose might be necessary. Always check the label for the actual EPA/DHA amounts, not just the total oil weight.
3. Purity and Freshness: Avoiding Rancidity and Contaminants
Fish oil can oxidize and go rancid, which not only tastes bad but can be harmful. Look for products that are molecularly distilled to remove heavy metals and PCBs. The SuperiOmega brand uses a patented stabilization process and includes natural tocopherols to resist oxidation. NOW Supplements also mentions molecular distillation in their quality control.
Freshness is key. If a softgel smells overly fishy or tastes unpleasant, it may be oxidized. Choose brands that are transparent about their sourcing and third-party certifications. For overall wellness, you might also be interested in essential nutrients for healthy circulation to support your cardiovascular system.
4. Serving Size and Softgel Count: Convenience Matters
Think about how many softgels you’re willing to take daily. Some products require 3 large capsules per serving, while others pack more into a single softgel. The NOW Tri-3D Omega provides 330mg EPA and 220mg DHA in just one softgel, making it easy to swallow. The SuperiOmega offers 1500mg total omega-3s in a serving, but you’ll need to check the label for the number of softgels.
Also consider the total supply. A 90-softgel bottle at 1 per day lasts 3 months, while a 60-softgel bottle at 2 per day lasts only 1 month. Factor in your budget and how consistent you’ll be. If you’re new to fish oil, you might want to start with a lower dose to see how your body reacts.
For a broader look at omega-3 sources, you can compare krill oil vs cod liver oil to see if a different source might suit your preferences.
Final Thoughts
When it comes to choosing between triglyceride and re-esterified triglyceride fish oil, both are effective, but rTG may offer slightly better absorption for those with sensitive digestion or higher needs. For a budget-friendly, high-potency option, the Omega 3 Fish Oil 2250mg Triglyceride Form from Intelligent Labs is a solid choice with a natural 3:2 EPA to DHA ratio. If you prefer a more affordable daily dose with balanced EPA and DHA, the Built by Nature Omega 3 Fish Oil 1400 mg for Women offers a clean rTG formula that supports heart, brain, and joint health. Whichever you pick, consistency is key to seeing benefits.
Frequently Asked Questions
What is the difference between triglyceride and re-esterified triglyceride fish oil?
Triglyceride (TG) fish oil is in the natural form found in fish. Re-esterified triglyceride (rTG) is a processed form where ethyl esters are converted back to triglycerides. Both are well absorbed, but rTG may have a slight edge in bioavailability, making it a popular choice for premium supplements.
Is rTG fish oil better than regular triglyceride form?
Research suggests rTG is absorbed more efficiently than ethyl ester forms, but compared to natural TG, the difference is modest. For most people, both TG and rTG are excellent. If you have a sensitive stomach or want maximum absorption, rTG might be worth the extra cost.
Can I take fish oil every day?
Yes, daily use is generally safe and recommended for most adults. The FDA suggests up to 3 grams of combined EPA and DHA per day is safe. Always follow the dosage on the label and consult your healthcare provider if you have underlying conditions or take blood thinners.
What is the best time to take fish oil?
Taking fish oil with a meal that contains fat can enhance absorption and reduce the chance of fishy burps. Many people prefer breakfast or lunch. Consistency matters more than the exact time, so choose a time you’ll remember. For more tips on heart health, check our supplements for healthy blood flow guide.
