We've heard about it, read about it, seen it promoted as a nutritional component in everything from canned tuna to oatmeal, to powdered milk. But do we really know what this amazing nutrient is and what it can do? Here's a quick backgrounder.
First things first—
WHAT IS DHA?
DHA is short for docosahexaenoic acid, one kind of omega-3 fatty acid.
These are essential oils that the human body needs to function normally BUT our bodies cannot produce on its own.
Because of this, we need to get DHA from other sources such as—
OILY FISH – salmon, tuna, sardines
VEGETABLE OILS – flax seed, soy, canola
OTHERS – chicken, eggs
WHAT CAN IT DO?
DHA CAN POWER UP THE BRAIN
When it comes to brain nutrients, DHA is one of the most widely-recognized of them all.
Here's an amazing theory about its brain-building power: some scientists believe that the inclusion of DHA in the diet of early humans may have contributed to the rapid expansion of their cerebral cortex—the first major step toward evolving into intelligent beings! 5-8
If you thought that was amazing, there is also scientific proof validating these same brain-building capabilities.
Clinical studies9-11 have shown that young children who received expert-recommended levels of DHA and ARA showed superior brain development in terms of problem solving, visual acuity, verbal intelligence, and IQ, compared to those who had not.9-11
Continuing to receive DHA throughout childhood is important to help keep the brain in optimal health.
DHA is also important even before birth, because this is the time when the newly-formed baby's brain develops very rapidly. Pregnant moms are advised to take lots of DHA, which will serve as the building blocks of her unborn child's brain.
Amazing right? It gets better. DHA has been shown to deliver a host of other health benefits.
DHA CAN BE GOOD FOR THE HEART
DHA helps reduce fats in the blood called triglycerides, blood pressure, and clogging in the arteries. It can also improve existing heart conditions and even prevent cardiovascular diseases, including heart attack and stroke.
DHA CAN HELP MANAGE ARTHRITIS, MENSTRUAL CRAMPS, AND MORE
By suppressing certain enzymes, DHA seems to decrease inflammation in the body and reduce the symptoms of rheumatoid arthritis. Unfortunately, it cannot prevent further joint damage.
Girls will be delighted to know that DHA may also lessen the pain of menstrual cramps, when taken on a regular basis.
Now that you're more informed about the importance of DHA, give your child expert-recommended levels every day. But beyond that, you must also support it with appropriate mental stimulation on a regular basis.

DHA: A BRIEF HISTORY
DHA has been around long before modern scientists began to tap its great potential.
The first study on omega-3 fatty acids is published, leading to hundreds more in the years that followed.
At the turn of the century, clinical tests revealed more positive results about its brain-building qualities.
Experts come out with the recommended levels of DHA per day to maximize its brain-building benefits. What are they? Click here to find out.
There are continuing studies on the many benefits that can be derived from DHA, including promising research that connects it to preventing heart disease, treating neurological and neuropsychiatric disorders, and even combating stress. But to us parents, its effects on improving our children's mental faculties are still the most exciting of all!
