2.What is rTG Fish Oil?
rTG stands for Re-esterified Triglyceride.
Traditional concentrated fish oils are often manufactured in ethyl ester (EE) form because EE processing allows easier concentration of EPA and DHA. However, EE fish oils may have lower absorption efficiency and reduced compatibility with the body’s natural lipid metabolism.
rTG technology converts concentrated Omega-3 fatty acids back into natural triglyceride form, significantly improving:
•Bioavailability
•Digestive absorption
•Stability
•Consumer tolerance
•Premium formulation compatibility
Our rTG-Pro Fish Oil contains:
•Average TG structure purity: 90%
