為何沒有DHA?
Why no DHA?

While it is the case that DHA is important structurally in the brain, a consensus has emerged in the scientific and medical community that it is EPA which is the more beneficial of the omega-3 fatty acids for optimal neurological function. More and more supplement companies are acknowledging this body of evidence and are gradually increasing the ratio of EPA to DHA to the extent that some forward-thinking companies, like ourselves, remove the DHA completely through molecular distillation. This oxygen-free process extracts the EPA, which is left "ultra-pure" and is most bio-available to the body.

The primary reason why omega product only contains ultra-pure EPA and absolutely no DHA is due to the fact that clinical trials show that as the ratio of EPA to DHA increases in a supplement, so does its effectiveness. In addition, some leading experts believe that DHA (docosahexaenoic acid) may inhibit the beneficial actions of EPA (eicosapentaenoic acid).

Professor Puri, Consultant at Hammersmith Hospital and Imperial College London, is the author of over 100 scientific papers and more than 20 books, including The Natural Way to Beat Depression, Chronic Fatigue Syndrome - A Natural Way to Treat M.E. and Attention-Deficit Hyperactivity Disorder - A Natural Way to Treat ADHD.

He explains: "In general it has been found that as the ratio of EPA to DHA rises in the supplement used in clinical trials of certain conditions, such as depression and attention-deficit hyperactivity disorder (ADHD), the ability of the supplement to improve the condition also rises."

For these reasons the EPA to DHA ratio in omega product capsules is the highest possible - omega product contains no DHA at all. Each omega capsule contains around 280 mg of ultra-pure EPA.

Igennus is not negating the use of DHA in all circumstances; its importance for the developing foetus, for example, cannot be over-emphasised. DHA also has properties which make it beneficial for cardiovascular and joint health. What should be recognised, however, is that these fatty acids have very distinct roles for health, particularly the role of EPA in brain function and mood disorders, for which DHA has little or no benefit. Studies have shown that for these conditions EPA alone is far more effective than in combination with DHA, which can inhibit the beneficial actions of EPA.

With the necessary co-factors the body can convert EPA into DHA as and when it needs it, preventing the unnecessary build-up which results from taking DHA in supplement form, thus avoiding any concerns about its high rate of oxidation.
