Why DHA Supplementation?
DHA is a kind of nutrient known as an omega–3 fatty acid. It is needed for normal brain function throughout life.
While DHA is found throughout tissues of the body, it is a major structural component of cell membranes in the
gray matter of the brain and retina of the eye. DHA is especially important for visual and central nervous system
development during gestation and the first two years after birth.
DHA Supports Growing Minds
As children grow and develop, they never lose their need for DHA (docosahexaenoic acid).
It's the most important omega-3 fatty acid for brain and vision health at every stage of life.
Here's Why DHA Is So Essential
DHA represents up to 97% of the omega-3 fatty acids in the brain and is especially concentrated in the area responsible for complex thinking skills.
Between birth and 5 years of age, the human brain increases approximately 350% in mass, with DHA content increasing 450%.
DHA represents up to 93% of omega-3 fatty acids in the retina and is necessary for optimal structure and function of nerve cells in the eyes.
DHA - For a Healthy Life
In many studies, Omega-3 Fatty Acids and DHA has been shown to reduce the risk of cardiovascular disease.
Research has shown that they may: 31
Decrease risk of arrhythmias, which can lead to sudden cardiac death
Decrease triglyceride levels
Decrease growth rate of plaque in the arteries
Lower blood pressure (slightly)
In addition, some scientific studies have indicated that DHA may be important for brain and eye health as we age.
DHA plays a significant role in the maintenance of normal neurologic function 32
DHA is necessary for the development and maintenance of optimal structure and function of nerve cells in the brain and eyes. 33
Preliminary research suggests DHA plays an important role in maintaining healthy mental function. 34
Adding DHA to Your Diet
Unless you eat a lot of fatty fish and organ meats, you probably won't get enough DHA through diet alone.
To get your 220 milligrams a day, look for supplements and foods fortified with life'sDHA™, the algae-derived vegetarian
DHA source that does not contain fish or fish oil.
The recommended dosage of IQ DHA is 100mg per day. (1- IQ DHA Capsule)
Those who eat little or no DHA rich foods should take 200mg of IQ DHA per day.
Today, the average Americans daily intake of DHA is significantly lower then it was 50 years ago.
Similarly, the level of DHA in breast milk of American women is significantly lower then it was 50 years ago.
An additional 200mg of DHA a day increases the benefits of the average American mother’s breastmilk to near historic levels.
Eco-Friendly - IQ DHA
IQ DHA™ from Neuromins does not deplete fish populations or expose
you to oceanic pollutants and toxins found in some types of fish.
