If you have ever shopped for an omega-3 supplement, you have likely seen terms like “triglyceride form” or “rTG” on labels. But what does that actually mean for your health? The chemical structure of omega-3 fatty acids affects how well your body absorbs them, and the triglyceride form is the natural way these fats appear in fish. In this guide, we explain the triglyceride form of omega-3, why it matters, and how to choose a high-quality supplement. We also review two products: the Igennus Ultra Pure Omega 3 rTG IFOS-Certified Wild Fish Oil and the FemiCore bladder-reset formula. Whether you are new to omega-3s or looking to upgrade your routine, this article will help you make an informed decision.
Pros
- IFOS certification guarantees exceptional purity and quality.
- rTG molecular form maximizes omega-3 absorption and effectiveness.
- High concentration (70% EPA/DHA) means fewer softgels needed for desired dosage.
- Lemon flavor minimizes aftertaste and digestive discomfort.
- Sustainably sourced from wild Pacific anchovies with Friends of the Sea approval.
Cons
- Premium price compared to standard fish oil supplements.
- Softgels may be larger than average, potentially difficult for some to swallow.
- Natural lemon flavor may not completely mask the fishy taste for sensitive users.
The Igennus Ultra Pure Omega 3 is a premium fish oil supplement designed for those who demand the highest purity and absorption. It targets health-conscious individuals, athletes, and anyone seeking to support brain, heart, and joint function with a concentrated, clean omega-3 source.
Its standout feature is IFOS certification, meaning each batch is independently tested for contaminants like mercury and PCBs. Combined with the re-esterified triglyceride (rTG) form, this oil is absorbed up to 3.5 times better than standard fish oils, delivering more EPA and DHA to your cells. The 70% concentration with a 2:1 EPA to DHA ratio is one of the highest available.
Design-wise, the softgels are moderately sized and coated with a natural lemon flavor to reduce fishy burps. The packaging is sturdy and opaque, protecting the oil from light and oxidation. Astaxanthin is added to keep the oil fresh and provide extra antioxidant support.
On the downside, this premium quality comes at a higher cost than many standard fish oils. Some users may find the softgels slightly large, and while lemon flavor helps, it may not eliminate all fishy aftertaste for very sensitive individuals.
Overall, the Igennus Ultra Pure Omega 3 is an excellent choice for anyone prioritizing purity, absorption, and potency. It delivers on its promises and is backed by rigorous third-party testing, making it a top-tier option for daily omega-3 supplementation.

Pros
- Targeted support for natural testosterone production
- Includes scientifically studied ingredients like zinc and vitamin D
- May improve workout performance and recovery time
- No artificial colors or preservatives

Prime Labs Testosterone Booster is a dietary supplement designed for men who want to support healthy testosterone levels naturally. It is especially targeted at men over 30, as testosterone production begins to decline after that age. This product claims to enhance strength, stamina, and overall vitality through a blend of vitamins, minerals, and herbal extracts.
The formulation includes zinc and vitamin D, both of which are well-researched for their role in testosterone regulation. Additionally, the supplement contains Tribulus Terrestris, a herb often used to boost libido and athletic performance. Users can expect to take two capsules daily with a meal for best absorption and consistency.
In terms of real-world performance, many testosterone boosters take several weeks to show noticeable effects. Prime Labs suggests gradual improvements in energy, mood, and workout intensity rather than instant results. The product is manufactured in FDA-registered facilities, which adds a layer of quality assurance, though individual results will depend on diet, exercise, and overall health.
A drawback is the lack of independent customer reviews, making it harder to gauge how effective this specific bottle is. Also, as with any supplement, it is not a magic solution and works best when combined with a healthy lifestyle. Some users may experience mild digestive upset when starting the regimen.
Overall, Prime Labs Testosterone Booster is a reasonable option for men seeking a natural boost in energy and strength. For best results, use it alongside resistance training and a protein-rich diet. While it has potential, we recommend consulting a healthcare professional before starting any new supplement routine.

The product is manufactured in the USA in a facility that adheres to good manufacturing practices, and each batch is third-party tested for purity and potency.

Buying Guide: What to Look for in a Triglyceride Form Omega 3 Supplement
1. Purity and Certification
Not all omega-3 oils are created equal. The best supplements undergo third-party verification to ensure they are free from contaminants like mercury, PCBs, and dioxins. Look for certifications such as IFOS (International Fish Oil Standards) or similar programs. For example, the Igennus Ultra Pure Omega 3 rTG is IFOS-certified, meaning it has been independently verified for purity and safety. This gives you confidence that you are getting clean, high-quality oil.
If you are curious about the best time to take omega-3s for maximum absorption, check out our guide on when to take omega-3.
2. Form of Omega-3: rTG vs. EE vs. TG
The form of omega-3 in your supplement directly impacts how well your body absorbs it. Standard triglyceride (TG) form is natural but less concentrated. Ethyl ester (EE) form is cheaper but less absorbable. Re-esterified triglyceride (rTG) form is the gold standard: it is molecularly reconstructed to mimic the natural triglyceride structure, leading to up to 3.5 times higher absorption than standard TG oils. The Igennus product uses rTG technology, ensuring your body gets more EPA and DHA per dose.

3. EPA and DHA Concentration and Ratio
Concentration matters: more EPA and DHA per softgel means fewer pills to swallow. Look for a product that provides at least 500 mg of combined EPA and DHA per serving. The ideal EPA-to-DHA ratio varies by goal, but a 2:1 ratio is common for general health. The Igennus supplement delivers 500 mg EPA and DHA per softgel with a 2:1 ratio, supporting brain, heart, eyes, skin, and joints. If you want to learn more about the EPA DHA ratio, see our guide on omega-3 EPA DHA ratio.
4. Additional Ingredients and Quality Assurance
Some omega-3 oils include antioxidants like astaxanthin to prevent oxidation. The Igennus product contains astaxanthin, which also gives the oil a natural pink hue and protects the delicate fatty acids. Also consider manufacturing standards: the Igennus supplement is made in the UK under GMP guidelines, is non-GMO, soy-free, and compatible with halal and kosher diets. For those with sensitive stomachs, a natural lemon flavor helps prevent fishy burps.
While our focus is on omega-3, we also want to highlight a different health category: bladder support. The FemiCore formula is a doctor-endorsed bladder-reset supplement for women. If you are interested, you can explore more in our bladder support category.
Final Thoughts
Choosing the right omega-3 supplement comes down to understanding the form, purity, and concentration. For maximum absorption and purity, the Igennus Ultra Pure Omega 3 rTG IFOS-Certified Wild is an excellent choice, especially if you want a high-potency rTG oil with verified quality. On the other hand, if your priority is bladder health, the FemiCore – $4 EPC Doctor-Endorsed Bladder-Reset offers a targeted solution endorsed by a trusted doctor. Both products serve distinct needs, so pick the one that aligns with your health goals.
Frequently Asked Questions
What is the triglyceride form of omega-3?
The triglyceride form is the natural structure of omega-3 fatty acids as they exist in fish. It consists of three fatty acids attached to a glycerol backbone. Supplements in rTG (re-esterified triglyceride) form are modified to mimic this natural structure, improving absorption compared to ethyl ester forms.
Is rTG omega-3 better than regular fish oil?
Yes, rTG omega-3 is generally considered superior because it offers higher bioavailability. Studies show that rTG forms can raise omega-3 levels in cells up to 3.5 times more than standard triglyceride oils. This means you get more benefit from each dose.
How much omega-3 should I take daily in 2026?
General recommendations range from 250 to 500 mg of combined EPA and DHA per day for healthy adults. However, for specific conditions, higher doses may be beneficial. Always consult a healthcare provider. For a detailed breakdown, see our guide on omega-3 dosage for men.
Can omega-3 supplements help with bladder health?
Omega-3s are primarily known for heart, brain, and joint health. Bladder health is a different area; products like FemiCore are specifically formulated for bladder support. If you are looking for bladder support, consider a dedicated supplement rather than omega-3.
