DHA – the fatty acid that shapes the health of the brain, the heart and immunity

Why DHA is regarded as an exceptional nutrient

DHA, that is docosahexaenoic acid, is a fat from the omega-3 group whose role in the body is considerably greater than it might seem. The stability of cell membranes, the efficiency of neurons and the quality of signalling between cells all depend on its presence. DHA is a key building block of the brain and of the retina of the eye, which is why its deficiency affects both cognitive abilities and the quality of vision. The human body produces only symbolic amounts of DHA, which is why it has to be supplied with food or through supplementation, especially in people with a demanding lifestyle.

DHA and the functioning of the brain and the nervous system

The central nervous system needs DHA for the efficient processing of information. This compound increases the flexibility of neuronal membranes, which makes possible a faster conduction of impulses and a more efficient formation of new connections. A high concentration of DHA in the brain favours concentration, resistance to stress and effective intellectual work. Clinical observations indicate that a low level of DHA correlates with a more frequent occurrence of mood disorders, irritability and problems with memorising. An increased supply of DHA in adults improves the speed of reaction, clarity of thinking and the ability to focus attention.

The importance of DHA in a child's development

In the prenatal period and in the first years of life, DNA and neurons take shape intensively, which is why DHA plays a fundamental role here. Its presence influences the development of the retina, the maturation of nerve cells and cognitive parameters. Studies have shown that children fed with milk rich in DHA achieve better results in cognitive tests, and their nervous system matures faster. This is precisely why DHA is one of the key ingredients recommended to pregnant women and to breastfeeding mothers – it is meant to enable the proper build-up of the child's brain and vision.

DHA and the health of the eyes

The retina of the eye contains one of the highest concentrations of DHA among all the structures of the body. It is responsible for the proper work of the photoreceptors and for adaptation to changing lighting conditions. An adequate concentration of DHA minimises oxidative stress within the eyeball and protects against macular degeneration. People working at monitors, drivers and children using screens have an increased requirement for DHA, because their organ of vision is more exposed to fatigue and micro-damage.

DHA in the prevention of cardiovascular diseases

The circulatory system benefits from DHA on many levels. This compound stabilises the rhythm of the heart, supports the elasticity of the blood vessels and limits inflammatory processes. The most important effect of DHA is a lowering of the level of triglycerides – a key risk factor for the development of heart disease. Regular supplementation reduces the viscosity of the blood, supports proper flow and improves the functioning of the endothelium. In combination with EPA, DHA forms one of the most effective duos supporting the health of the circulatory system.

The link between DHA and the body's immunity

Inflammatory states are a natural element of the body's functioning, but their chronic form leads to a whole range of disorders. DHA supports the production of anti-inflammatory cellular mediators, thanks to which it eases uncontrolled inflammatory processes in the tissues. Its presence improves the immune response and supports the body in the fight against infections. DHA accelerates regeneration, strengthens the immune cells and helps to maintain the stable work of the immune system.

Symptoms and effects of a DHA deficit

A lack of an adequate amount of DHA does not remain without influence on the body. A drop in the ability to concentrate, mood disorders, tiring quickly and fluctuations of energy are among the first warning signals. In children a deficit of DHA may affect neurological development and worsen memory and language abilities. In adults, deficiencies increase the risk of cardiovascular diseases, weaken visual acuity and cause a lowering of immunity.

Natural sources of DHA

The richest sources of DHA are oily sea fish: salmon, herring, mackerel, sardines and halibut. Vegans and vegetarians can obtain DHA from marine algae, which are a stable source of omega-3 acids in a form that is bioidentical for the human body. The contemporary diet often does not cover the requirement for DHA, which is why supplementation becomes a necessity.

DHA supplementation – how to select the right amount

DHA occurs in supplements in various chemical forms: triglycerides, ethyl esters and phospholipids. The best absorbed are the natural forms and products enriched with antioxidants that protect the fats against oxidation. The recommended doses range from 250 mg to 1000 mg a day, while pregnant women need a minimum of 400–600 mg. Seniors, people under stress or doing intensive mental work often require higher doses.

Advanced DHA formulas from DWATRO Laboratories

The DWATRO Laboratories brand offers advanced DHA preparations created with the use of liposomal technology, which increases the bioavailability and the stability of omega-3 acids. Thanks to the DWATRO®LIP system, the active substances reach the cells directly, which increases the effectiveness of supplementation. These products combine DHA with vitamin D3, vitamin E or coenzyme Q10, creating versatile support for the brain, the heart and immunity. The innovative DWATRO Laboratories formulas stand out for their high purity, the absence of heavy metals and excellent absorbability.

Summary

DHA is a nutrient of exceptional importance for the health of the brain, of vision, of the heart and of the immune system. Its deficiency is quickly reflected in concentration, mood and general vitality. Supplying DHA regularly – both with the diet and in the form of supplements – is one of the most effective ways of supporting cognitive functions and of protecting the circulatory system. DWATRO Laboratories preparations, thanks to liposomal technology, provide high absorbability and effectiveness of action, making DHA one of the most important elements of everyday health prevention.

My name is Dorota Wątróbska-Świetlikowska, I am a pharmacist and a scientist holding a habilitated doctorate in pharmaceutical sciences. I decided to combine my scientific knowledge and experience in order to create dietary supplements of the highest quality.

My passion and main area of research are submicron dispersion systems, such as submicron emulsions, liposomes and lipospheres. After obtaining my doctorate, I turned my attention to the practical aspects of parenteral nutrition, combining the needs of the patient with the possibilities of the pharmacist. Quality, safety and effectiveness are the most important things for me , which is visible both in my scientific work and in my approach to creating supplements from Dwatro Laboratories®.
