Eicosopentanoic acid (EPA) and decosahexanoic acid (DHA) are omega 3 fats found in cold water fish such as salmon, trout, mackerel, sardines
Humans tend to be severely deficient in DHA, as compared to EPA. This is why I recommend supplementation with more DHA as opposed to EPA. The VitaFish Oil from VitaTree Nutritionals contains a 40:10 ratio of DHA to EPA, yielding 400 mg of DHA per day. This is the important brain omega 3 fat necessary for cognition and brain function. DHA also concentrates at the back of the eye in the retina and is responsible for proper vision. It is important that DHA is supplemented everyday, as our brain uses its stores daily.
DHA is a 22 carbon chain, with 6 double bonds, whereas EPA has 20 carbons and 5 double bonds. The body can easily convert DHA to EPA if required because it can easily lose 2 carbons to become EPA, however the EPA has difficulty converting to DHA by adding 2 carbons. This is why I think we all need to be supplementing with more DHA than EPA daily.
DHA is concentrated in fast twitch muscles, like the heart, eyes and fast twitch skeletal muscles. Athletes, like sprinters who use fast twitch muscles, need to replenish more DHA than a sedentary person. It is interesting to note that hummingbirds have a high amount of DHA in their wings, and rattlesnakes in their rattle, as composed to their bodies. DHA also has been proven to be higher in individuals with faster metabolisms, and is one of the reasons I recommend taking the VitaFish Oil about an hour before exercise, to improve metabolism and feed the muscles with the DHA they require.
VitaFish Oil can be taken in capsule form, 4 capsules a day, with food. VitaFish Oil is so fantastic because it tastes like candy, and doesn’t have any fishy taste or aftertaste. It is in small little orange softgels, that can be either swallowed or chewed. Kids love them and take them willingly because they taste so great!
