EFA's or EssentialFatty Acids, are naturally occurring unsaturated fats that areconsidered essential because they are not produced by the human body.There are two EFA's, they are linoleic, sometimesreferred to as the Omega-6 fatty acid, and alpha-linoleic, referred toas the Omega-3 fatty acid. Without these essential fatty acids,several bodily functions would not be possible. The body useslinolenic acid to make two other essential fatty acids,docosahexaenoic acid, commonly referred to as DHA, andeicosapentaenoic acid, or EPA. These fatty acids are found in fish oilas well.
The role that EFA'splay in our bodies is significant and might surprise you. One of themajor roles of EFA's in the body is as structural components of allcell membranes. In addition to this, EFA's are vital for the formationof hormone-like substances called prostaglandins which are vital for avariety of functions including steroid hormone production. It isimportant to keep in mind that although our diets seem to beexcessively loaded with fat, these fats are of the saturated varietyand do nothing to improve overall body function except as stored fatdeposits. It is important to consume enough EFA's and as littlesaturated fat as possible in order to promote proper overall bodyfunction. I-Supplements only provides top quality articlesand supplements.
As with othersupplements, EFA's have plenty of research proving their benefits.Some studies have demonstrated that supplementing the diet with EFA'smay decrease catabolism and increase growth hormone secretion. Otherstudies have shown that EFA's may improve the action of insulin andcould possibly enhance oxygen utilization and the energytransformation necessary for optimal performance. Still other studieshave demonstrated that EFA's can have a positive impact on totalcholesterol levels and can increase levels of HDL, or the goodcholesterol. Finally, and perhaps the most exciting of all studies,found that supplementing with EFA's, specifically CLA, may support asignificant increase in fat loss and an increase in lean body mass.
There have been nodefinitive studies as to what doses are the optimal. The recommendeddose depends on a persons eating habits, metabolism and genetics.Usually, in conjunction with a low-fat diet, consuming 3-9 total gramsper day has been shown to be sufficient.
As of yet, there havebeen no reported or known side effects from taking EFA's. As statedbefore, EFA's are abundant in nature, such as fish oils, and vegetableoils, and thus no adverse side effects should be encountered.
