Tg in fish oil refers to Triglycerides, the natural form of fat in which omega-3 fatty acids like EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are found.
Understanding Triglycerides in Fish Oil
Fish oil naturally contains omega-3 fatty acids in the form of triglycerides. These triglycerides are the way EPA and DHA are primarily stored in fish.
- Natural Form: Triglyceride (TG) fish oils represent the natural state in which these beneficial fatty acids exist.
- EPA and DHA Content: Typically, TG fish oils provide a maximum combined EPA and DHA content of around 30%. This means that in 1,000 mg of fish oil, you'll find approximately 300 mg of combined EPA and DHA.
Comparison to Ethyl Esters (EE)
It's important to distinguish between triglycerides (TG) and ethyl esters (EE):
- Ethyl Esters (EE): These are created through a process to concentrate EPA and DHA in fish oil. This process can increase the EPA and DHA content beyond the natural 30% found in TG form.
- Absorption: Some studies suggest that triglycerides are absorbed better by the body compared to ethyl esters, although this is a topic of ongoing research and debate.
Key Takeaways
- TG fish oil is the natural form where EPA and DHA are bound to a glycerol backbone.
- EE fish oil is a processed form designed to increase the concentration of EPA and DHA.
- The choice between TG and EE fish oil depends on individual preferences and needs, considering factors like concentration, absorption, and cost.
In summary, Tg in fish oil signifies the triglyceride form, representing the natural structure of fats containing omega-3 fatty acids like EPA and DHA.
