This is a highly refined form of fish oil where omega-3 fatty acids are converted back into their natural triglyceride structure after purification. Known for better absorption and higher bioavailability.* **Q: Why is your fish oil dark in color?** A: Naturalis rTG fish oil has a dark red color because it contains astaxanthin. The inclusion of astaxanthin may also give the oil a mild ‘seaweed-like’ scent, as it is derived from natural microalgae. **Q: Is your fish oil third-party tested?** A: Yes, all Naturalis fish oil products undergo third-party testing for purity, stability, and safety. This rTG fish oil is certified by IFOS, ensuring it meets strict global quality standards. **Q: What is the purpose of adding astaxanthin and vitamin E to your fish oil?** A: Astaxanthin and vitamin E are added as antioxidants. They mainly aim to help the fish oil preserve freshness and potency. They also provide some extra benefits with their antioxidant nature. **Q: Is the astaxanthin in your fish oil natural or synthetic?** A: The astaxanthin used is 100% naturally sourced from microalgae. It is cultivated in a closed tubular system, which prevents contamination from open seawater. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good choice *by L***C on July 18, 2026* Very pleased with Omega 3 tabs have no problems swallowing nor doesn’t have after taste ### ⭐⭐⭐⭐⭐ Sin regusto. *by F***Z on July 24, 2026* Sin regusto a pescado.
