Now Foods DHA-500 is a powerful dose of essential fatty acids extracted from fish oil that does not contain poisonous chemicals (dioxins, polychlorinated biphenyls and heavy metals). The high content of DHA and EPA ensures the proper condition of the nervous, immune and cardiovascular systems.

Docosahexaenoic acid (DHA) belongs to the long-chain unsaturated fatty acids that build the membranes of various cells. Its high concentration is particularly visible in the brain. It also guarantees the correct synthesis of neurotransmitters such as dopamine and serotonin. They are responsible, among others, for the feeling of pleasure, which is why they are often called ‘the happiness hormones’.

Eicosapentaenoic acid (EPA) is another of the omega-3 fatty acids group that may be a precursor to DHA. Physiologically, it acts as a blocker of the phospholipase A2 enzyme, which is involved, inter alia, in the production of proinflammatory prostaglandins. It also supports the memory processes, which results in better interneuronal transmission.

Powerful brain support
Cell membranes are made of so-called phospholipid bilayer, which consists of unsaturated fatty acids, giving it semi-liquidity. Their greatest concentration is in the central nervous system, where they play a double role.

First of all, they are the building material for myelin sheaths that participate in the process of the nerve impulse transmission. Their improper structure results in neurological deficits, which appear depending on the location of their occurrence. In addition, DHA is involved in the synthesis of important neurotransmitter substances that regulate parameters which are  important for the functioning of the whole system, such as body temperature, sleep and wakefulness, sexual tension, pleasure or motor coordination.

Retina- another part of the nervous system also contains a high concentration of EFA. Their presence ensures the correct visual acuity and allows for long-lasting good eyesight.

Rescue for the circulatory system
One of the more frequent disorders that occur in the cardiovascular system are the common states of increased blood clotting. They are usually formed in blood vessels that have been damaged by atherosclerotic lesions or chronically elevated blood pressure. They lead to the formation of blood clots that, when wandering with the bloodstream, can close important arteries in the heart or brain. This results in ischemia leading to a stroke or myocardial infarction.

However, blood vessels can ‘defend’ against this unfavorable phenomenon by synthesizing appropriate substances that have anti-thrombotic and myorelaxant effects. One such substance is, among others, prostacyclin which is produced from the omega-3 fatty acids supplied to the body. It lowers the blood pressure and inhibits the thrombocyte aggregation.

Immunoregulation at the highest level
The cells of the immune system communicate with each other using substances with a parahormonal effect. They include cytokines, and derivatives of arachidonic acid - prostaglandins, as well as leukotrienes. Their production enables an effective defense against pathogenic germs, mobilizing the body's defense system to resist the intruder's attack. The problem arises at the time of overproduction of pro-inflammatory compounds which overstimulate immunocompetent cells. This leads to auto-aggression reactions and destruction of the body's own structures.

To prevent such conditions, supplementation with omega-3 acids is helpful. From these acids are produced the derivatives of prostaglandins and leukotrienes with anti-inflammatory activity that regulate the immune system. This promotes the restoration of the correct response of the cells and their response to the actual threat to the system.

In conclusion, Now Foods DHA-500 is a product supplementing dietary deficiencies of omega-3 acids. Each capsule contains the highest quality toxin-free fish oil, abundant in EPA and DHA acids. The preparation is recommended for anyone who wants to support cardiovascular health or cognitive functions, as well as reduce the occurrence of inflammation.

Calories are the conventional name of the unit expressing the energy value of food, the demand and energy expenditure in human body, which in fact is 1 kilocalorie (1 kcal). 1 kilocalorie is the amount of thermal energy required to heat 1 g of water and 1 degree Celsius. The SI unit of thermal energy is 1 joule (1J), equal to approximately 4,185 kcal.
The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents. Most often Atwater equivalent is used: ratio for protein 4 kcal / g, for carbohydrates 4kcal / g, and for fat - 9kcal / g.
The energy value carried out with the so-called. "Caloric bomb" is equivalent to the physical energy, amounting to 4.1 kcal per 1 g carbohydrate to 5.65 kcal per 1 g protein, 9.45 kcal per 1 g of fat.
Nutritional value, determines the suitability of a food product for realizing life functions of human, the higher it is - the higher bioavailability and lower quantity for consumption for obtaining the effects.




Fat is an essential nutrient plant and animal organisms. Because of the nutritional value and composition of fats are divided into: saturated (mono-saturated and multi-saturated fatty acids) and unsaturated fatty acids (including essential fatty acids - EFA). The group of lipids include lipids (triacylglycerols, waxes), complex fats (glycolipids, phospholipids), sterols and isoprenoids. Saturated fatty acids is a group of fatty acids having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is bound by a single bond. May adversely affect the lipid profile, so they can be used in limited quantities. Fats are a concentrated source of energy, with different flavours, facilitating the consumption and swallowing of food. They have building functions (part of cell membranes and co-create the white matter of the brain). EFAs are precursors of tissue hormones and biologically active compounds. The unsaturated fatty acids include fatty acids from the group Omega-3, Omega-6 and Omega-9 (the last digit indicates, on which, counting of the end of the chain, there is a double bond in the appropriate carbon chain. The essential fatty acids include: acids, medium-Omega-3 [n-3 ] included in EFAs [essential fatty acids], and long chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) Omega-6 and Omega-9. the number indicates that the last double bond in the carbon chain is on the third from the end carbon atom. The acids from the omega 3 group are essential components of cell membranes, they are precursors of eicosanoids and biological activators. They must be combined with ingestion in suitable proportions of Omega-6 acids.
Dosage: Depending on demand and applied diet. It is generally accepted that fats should constitute 20-30% of the energy (calorie) of meals daily.


Fish Oil


Fish oil is a source of long chain saturated fatty acids of the Omega-3 (EPA - eicosapentaenoic acid; DHA - docosahexaenoic acid), which are part of cell membranes and the precursor of eicosanoids, and an activator. When consuming acids Omega 3, it must be balanced with the Omega 6 (using in the range of from 1: 6 to 1: 1). Fats contained in fish oil help to reduce body fat, affect the oxygenation of the body, and the operation of systems: circulatory, respiratory, nervous system and the musculoskeletal system. Available in the form of mono-preparation supplement or as an ingredient of supplements in the category of "health and beauty".



Omega 3


Omega-3 (n-3) group of unsaturated fatty acids: short-chain (linolenic acid, belongs to the EFAs [essential fatty acids]) and long-chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]). The number 3 indicates That the last double bond in the carbon chain is the third from the end of carbon. Acids from the group of Omega-3 are essential components of cell membranes, they are biological precursors and activators of eicosanoids. EFAs quite abundantly supplied in food, and it can be supplied with food. EPA and DHA (oils, fats marine fish) are Supplied by foods of sea origin (sea fish and seafood). They are developed also in the human body as a result of processes of denaturation and elongation of alpha-linolenic acid , but in an amount insufficient for the full needs of the organism. Therefore,they should be supplied from the outside. With the use of so-called. western diet, supplementation of fatty acids Omega 3 is more desirable (than Omega 6).
Supplementation of fatty acids of Omega 3 is recommended for people who are physically active in order to supplement and to prevent deficiencies in body as well as due to their impact on the body composition and aerobic capacity, and tissue regeneration. In addition, it regulates the systems: circulatory (including heart), nervous, respiratory and locomotor. Formulations containing EPA and DHA are a complement to an effort diet, regardless of the degree of training and exercising.
Dietary fatty acids Omega 3, in principle, are produced in the form of capsules in combination with vitamin E as an antioxidant, available for purchase at:
Dosage usually we recommended supplements in sports: depending on the supply of diet and intake of Omega 6 it is 1 - 5 g of EPA and DHA / 24 h.

DHA (Docosahexaenoic acid)


DHA (docosahexaenoic acid) - acid of omega-3 family, unsaturated fatty acids with the last double bond in the chain located on the third carbon atom from the end. Synthesized in the human body to eicosapentaenoic acid, or retrieved from foods of marine origin (fish, particularly salmon). In the medicine it is indicated for the treatment of depression, Alzheimer's ADHD. There has been its positive impact on the insulin metabolism noted as well as on endocrine and cardiovascular systems. When used in appropriate doses, it has a beneficial effect on the composition and appearance of the body. In the the supplementation it is part of formulas containing fish oil, which fill in the gaps of unsaturated fatty acids Omega 3, recommended for people with different physical activity.
Dosage: 200-2000 mg per day


EPA (eicosapentaenoic acid)


EPA (eicosapentaenoic acid) – what is it?

EPA (eicosapentaenoic acid) is a long-chain, polyunsaturated omega-3 fatty acid. The chain of the fatty acid consists of 20 carbon molecules, and the first bound out of five double bounds is located at the third carbon from the omega end, which is characteristic for omega-3 acids. It is present in large quantities in fish oils, where it is accompanied by docosahexaenoic acid (DHA).

EPA is a precursor to prostaglandins and other eicosanoids, which contributes to the reduction in inflammations. It is involved in inhibition of platelets aggregation. It contributes also to the reduction in triglycerides level in blood. EPA block the activity of an enzyme, phospholipase A2, present on cell membranes, which under the influence of stressors can release polyunsaturated fatty acid (from the group of eicosanoids) into the glycerol skeleton. To some extent, EPA can be also converted into 22-carbon DHA. The both acids have positive impact on the condition of the nervous system and cardiovascular health.
