What does “rTG” fish oil mean?

“rTG” stands for re-esterified triglyceride. 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.*

Why is your fish oil dark in color?

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.

Is your fish oil third-party tested?

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.

What is the purpose of adding astaxanthin and vitamin E to your fish oil?

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.

Is the astaxanthin in your fish oil natural or synthetic?

The astaxanthin used is 100% naturally sourced from microalgae. It is cultivated in a closed tubular system, which prevents contamination from open seawater.
