Product Introduction
DHA oil , also known as docosahexaenoic acid oil , is a dietary supplement that contains a concentrated form of DHA, 
 which is an omega-3 fatty acid. DHA is an essential nutrient that plays a crucial role in brain development, cognitive function, and overall health. 
The majority of people consume far too little of what are known as Omega 3 fats. These are very healthy fats mainly found in oily fish (such as mackerel and sardines).
When someone doesn't have enough Omega 3 in their diet, it can lead to numerous health problems 
This is why health experts almost always recommend that people increase their Omega 3 intake and why fish oil is typically thought of as being an incredibly important, popular supplement.
DHA plays a key role in the development of eye and nerve tissues. DHA might also reduce the risk of heart and circulatory disease by decreasing the thickness of the blood, reducing swelling (inflammation), and lowering blood levels of triglycerides.
Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is found along with eicosapentaenoic acid (EPA) in cold-water fish, including tuna and salmon.

People commonly use DHA for high levels of cholesterol or other fats in the blood. It is also used for boosting memory and thinking skills, for helping infant and child development, for certain eye disorders, and many other conditions, but there is no good scientific evidence to support many of these uses.
Don't confuse DHA with EPA. They are both in fish oil, but they are not the same. DHA can be converted into EPA in the body in very small amounts.

Considering how vital the healthy fat docosahexaenoic acid (DHA) is, it’s no wonder more people are taking DHA supplements to support their nervous system, heart, and brain than ever before.
Fortunately, as studies continue to demonstrate the importance of DHA for both adults and children, supplements and foods that provide docosahexaenoic acid are becoming more widely available. This means it’s now relatively easy to include sources of DHA in your diet regularly, especially the richest food sources of omega-3s like wild-caught fish, such as salmon, sardines, and herring.
If you’ve ever tried to buy fish oil or algae supplements before, you’re probably aware of just how many options there now are to choose from. In addition to eating oily fish, DHA supplements are recommended for most people  — whether you’re pregnant, looking to give docosahexaenoic acid to your child or you’re an adult who wants to maintain healthy cognitive function as you age.
What Is DHA?
Docosahexaenoic acid is a polyunsaturated omega-3 fatty acid found throughout the body that is important for normal brain function, including growth and development of the infant brain.
It is a major structural fat, making up 97 percent of the omega-3s found in the brain and 93 percent of the omega-3s found in the retina of the eyes. It is also a key component of the heart.
Docosahexaenoic acid is the prominent structural fatty acid found in the grey matter of the brain and retinal tissues in humans. Granule neurons in the hippocampus (the part of the brain that is primarily associated with memory) continue to proliferate throughout life. The formation of these newly proliferated cells in the hippocampus helps explain why dietary DHA is crucial for the maintenance of learning and brain function in older age.
Benefits
How exactly does DHA impact our health, and what are the benefits of obtaining it from supplements and foods?
1. Supports the Nervous System
Having adequate intake of DHA is important in adults when it comes to the health and function of the brain. It is also needed for proper brain growth and development in infants, as well as maintaining normal cognitive function into older age.
Humans obtain DHA primarily from their diets because we only have the capacity to synthesize a limited amount. The brain actually prefers DHA to other fatty acids, so uptake of it is higher than other fats. DHA turnover is also very fast, which means the brain needs a steady supply.
2. Supports Fetal/Infant Development
Why is DHA good for babies? Infants acquire it in utero during pregnancy and from breast milk. Neural function and integrity can be damaged permanently by deficits of omega-3 essential fatty acids during fetal and neonatal development. The DHA in the cerebral cortex starts to increase with age, primarily due to the length of breastfeeding.
Studies suggest that one long-term benefit of infants with higher levels of DHA is faster development of behavioral functions. Specific DHA deficits may lead to learning impairment because docosahexaenoic acid is involved in cell signaling.
If a mother is healthy and consumed dietary docosahexaenoic acid or DHA supplements, a breastfed baby should be able to get enough DHA from the mother’s breast milk. Infant formulas may or may not supply DHA, so it’s important to read labels carefully if you plan to formula-feed your infant.
During the last 50 years, many infants who were formula-fed lacked DHA and other omega-3 fatty acids. Some speculate that this has contributed to the rise in learning disabilities, including ADHD, though more research is needed to verify this.
Still, recent studies have found that lower levels of omega-3s are found in ADHD patients’ blood compared to those without ADHD, and it appears omega-3 supplements may help prevent ADHD.
3. Supports Vision and Eye Health
DHA plays a major role in the development of proper visual function in infants. Studies with both premature and full-term infants suggest that an adequate supply of docosahexaenoic acid, sourced either from breast milk or DHA-fortified formula, is associated with better visual function and more rapid visual development, which is why docosahexaenoic acid is an important eye vitamin.
The retina contains a high concentration of DHA, which enhances visual function, fluidity of photoreceptor membranes and retinal integrity. Many studies demonstrate that docosahexaenoic acid has a protective role in the retina.
Experts now tell us that from a nutritional standpoint, older individuals who tend to have a higher than optimal omega-6/omega-3 ratio should make an effort to increase DHA  consumption (from food and/or fish oils) to help protect their vision.
4. Treats Rheumatoid Arthritis Symptoms
Low DHA levels have been found to be associated with the development of rheumatoid arthritis, an autoimmune inflammatory disease that negatively affects joints and leads to the destruction of bone and cartilage. DHA reduces inflammation in the body, so it may help decrease damage, swelling, and pain in the joints of people with rheumatoid arthritis.
