Microalgal DHA

What is DHA?

Docosahexaenoic acid (DHA) is a necessary element during the growth of infants and children, and also a necessary supplement benefiting for the health of adults. Because DHA cannot be synthesized in human body and daily intake from dietary sources is insufficient, it is essential to consume special DHA supplemental products. .It is suitable for vegetarians and vegans due to its sustainable microalgae sourcing. The microalgae is “cultivated in a strictly controlled environment. It is extracted using an entirely natural enzymatic process with no solvents, then subjected to a high-tech purification and concentration process.”As a natural, safe, environment-friend functional food additive, microalgal DHA has drawn extensive attention and been applied widely in some countries. Meanwhile, it will be developed as a popular healthcare product and applied in food industry in China. However, technical problems in the application of microalgal DHA still need to be further investigated.As a new functional food additive, microalgal DHA will become a development tend of healthcare and food industries.


The Advantage of Microalgal DHA

l No fishy odour

l High clarity

l Entirely natural enzymatic process with no solvents

l Subjected to a high-tech purification and concentration process

l Higher DHA content, Low or even no content of the EPA

The Benefits of Microalgal DHA

l Supports Healthy Pregnancy

The omega fatty acid DHA is essential for brain development during a healthy pregnancy. Studies have shown that when a pregnant women consumes omega-3s, it improves the child's development. Omega-3 requirements increase during pregnancy in order to aid brain growth, especially as it accelerates during the second half of pregnancy.

Researchers have used a variety of tests, such as general developmental milestones, problem solving and language development, to assess neurodevelopmental outcomes among infants whose mothers were supplemented with omega-3 fatty acids compared with those who were not. A 2004 study conducted by Harvard Medical School and Harvard Pilgrim Healthcare found that higher maternal DHA consumption during pregnancy resulted in higher novelty preference on visual recognition memory and higher scores of verbal intelligence.

Animal studies have demonstrated that deprivation of omega-3 fatty acids, which is present in algal oil, during pregnancy is associated with visual and behavioral deficits that cannot be reversed with postnatal supplementation. This is why guidelines have recommended that pregnant women consume at least 200 milligrams of DHA per day.

l Boosts Eye Health

The brain and eye are highly enriched with omega-3 fatty acids, which accumulate in these tissues during late fetal and early neonatal life. A scientific review conducted by the Agency for Healthcare Research and Quality (U.S.) states that “clinical research has only scratched the surface with respect to understanding the possible utility of the intake of omega-3 fatty acids as a primary or secondary prevention in eye health.”

It’s known that there are very high levels of DHA present in the retina, and the role of DHA may be related to its biophysical effects on the cell membrane. It’s believed that DHA may modulate the activity of membrane-bound enzymes, which are responsible for the maintenance of cellular function. It may also regulate the receptors and kinetics of membrane transport systems.

Macular degeneration is a condition that is age-associated vision loss and blurry vision related to damage to the macula, or center of the eye. This can be a result of aging, poor digestion, smoking, high blood pressure, exposure to UV radiation and a low-vegetable diet. A natural treatment for macular degeneration is omega-3 fatty acid capsules that contain DHA because it helps relieve intra-ocular pressure.

l Supports Cardiovascular Health

Algal oil helps regulate heartbeat, reduce blood pressure, decrease blood clot formation and reduce overall inflammation; this decreases the risk of heart attacks and strokes. Algal oil also helps reduce triglycerides and LDL cholesterol.

A 2012 study published in the Journal of Nutrition identified 11 randomized controlled trials with 485 healthy participants and evaluated the relation between algal oil DHA supplementation and cardiovascular disease risk factors. The results indicate that DHA supplementation from algal oil may reduce serum triglycerides and increase HDL cholesterol and LDL cholesterol in persons without coronary heart disease.

l Aids Cognitive Development and Function

Omega-3 foods are important for cognitive development and function. The brain is made mostly of fat, and it functions especially well with high levels of DHA, which help the brain’s communication processes and reduce inflammation, which can help slow aging.

DHA is also required for the functional development of the brain in infants and maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability, whereas deficiencies of DHA are associated with deficits in learning.

Another interesting benefit of algal oil and other DHA foods is they’re able to reduce the symptoms of anxiety and depression. The European Journal of Neuroscience recently published a study earlier this year showing that oil containing omega-3s reversed all anxiety-like and depression-like behavior changes induced in rats. This is an interesting study because it stresses the importance of supplementing with omega-3s and DHA-rich oils at “critical periods of brain development,” which is why we should give it to our kids from early on to help them so they won’t develop anxiety or depression later in life.

l Improves Memory

Studies have shown that higher intakes of omega-3 oils significantly reduce the incidence of Alzheimer’s disease as well as vascular dementia; oils like algal also improve quality of life and memory in those affected by dementia.

Alzheimer’s disease is a brain disorder that progressively causes memory loss, dementia and early mortality. Memory loss is caused when plaque forms in the brain.

A 2012 study published in the Journal of Alzheimer’s Disease found that omega-3 fatty acid supplementation improved cognitive function; this effect appeared larger in rats compared to mice and in males compared to females. The fatty acid supplementation also diminished the amount of neuronal loss, especially in female animals.

l Reduces Inflammation

Preliminary studies suggest that omega-3s may help improve symptoms of osteoarthritis and joint pain. Inflammatory bowel disease may also be relieved with omega-3 supplementation. Because people today, consuming the standard American diet, don’t boost their omega-3 intake to balance out the elevated omega-6s they consume regularly, there has been an onslaught of chronic diseases and inflammatory processes. By reducing inflammation, which is at the root of most diseases, with algal oil or omega-3 supplements, you place your body in a state that is conducive to healing from these diseases and other health conditions.

One inflammatory condition is osteoarthritis, which occurs when cartilage between joints wears down, causing inflammation and pain. This type of arthritis generally occurs in the joints we most frequently use, such as knees, hips, spine and hands. By reducing inflammation in the joints, algal oil serves as a natural arthritis cure, and it reduces swelling and pain significantly.

Another condition that can be treated naturally with algal oil is inflammatory bowel diseases, which generally causes severe symptoms, such as diarrhea or ulceration of the digestive tract. This illness can often be related to a number of other health conditions, including ulcerative colitis, Crohn’s disease and leaky gut syndrome. Algal oil can reduce inflammation in the GI tract and serve as an IBS food treatment.
