Why Re-Esterified Triglyceride (rTG) Omega-3 Is the Smarter Choice for Better Absorption

Introduction

If you’ve ever compared different types of Omega-3 supplements, you’ve probably seen terms like ethyl ester, triglyceride, and re-esterified triglyceride (rTG). But what do they really mean? And does the form of Omega-3 truly matter?

At PURE SERVING™, we use the Re-Esterified Triglyceride (rTG) form, the most bio-available and premium version of fish oil — designed for better absorption and efficiency.

1. What Makes rTG Omega-3 Different?

Most generic fish oils come in ethyl ester form, which is created during processing.
However, in the rTG form, Omega-3 fatty acids are re-attached to natural triglycerides — restoring their native structure, closer to how fish naturally store fats.

This means your body can absorb and utilize EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) more efficiently.

2. Why Absorption Matters

Omega-3s only work when your body absorbs them effectively.
Studies show that rTG Omega-3 can offer up to 70% higher bioavailability than synthetic ester forms. That’s why PURE SERVING™ ensures every softgel delivers Omega-3 in its natural rTG structure.

3. Purity and Source

PURE SERVING™ sources its Omega-3 from premium sardine fish oil, known for naturally low mercury content and clean marine quality.
Each batch is tested for:

  • Heavy metals (mercury, lead, arsenic, cadmium)

  • Peroxide value (freshness indicator)

  • EPA + DHA content accuracy

Conclusion

The form of Omega-3 you choose determines what your body truly receives.
