Not all fish oils are created equal. Xtend-Life uses natural triglyceride oils that have superior bioavailability. Let’s take a closer look at that.
When we consume seafood, the omega 3s are in their natural form, called triglycerides. In contrast, when most manufacturers purify and concentrate fish oils, the oil is converted to a form called ethyl esters. This is needed for the distillation process, which requires high heat.
The problem with ethyl esters is that they are poorly absorbed by the body. One study showed that the maximum level of omega 3 (DHA and EPA) in the blood was
about 50% lower with ethyl esters compared to triglycerides. Fish oils in the ethyl ester form are the most common type of supplements because they are less expensive to produce.
Some fish oil manufacturers take another step (called trans-esterification) to turn the ethyl esters back to triglycerides. But there is a catch! In re-creating the triglyceride in this way, the molecule ends up in a different chemical structure compared to the natural form.
When it comes to fish oils, we believe nature knows best! That’s why we only use oil in their NATURAL TRIGLYCERIDE form. To manufacture our purified, concentrated fish oils and maintain their NATURAL TRIGLYCERIDE form requires a propriety enzymatic step that is technically difficult and also expensive.
Xtend-Life’s omega blend contains two fish oils which contain NATURAL TRIGLYCERIDES (DHA and EPA), with no conversion to ethyl esters. That makes Xtend-Life’s omega 3 products far superior to most other fish oil supplements on the market, so you can be confident you are getting the most effective type of fish oil available.
