What Is DHA?

Docosahexaenoic acid (DHA) is an important polyunsaturated fatty acid and an essential nutrient for the development of the human nervous system and visual system. DHA is found in high concentrations in the human cerebral cortex and retina and is important in maintaining the nervous system and visual function.

Sources from

Traditional sources: DHA is usually found in high concentrations in fish and seafood, especially oily fish such as salmon, mackerel, and sardines.

Algal oil sources: Unlike fish oil, DHA algal oil comes from microalgae, making it a plant-based and sustainable alternative.

Others: Some nuts, seeds, and dairy varieties contain small amounts of DHA.

How To Produce DHA Algal Oil?

Microalgae cultivation. Microalgae used to produce DHA algae oil are cultivated in a controlled environment, which helps ensure purity and minimize contamination from environmental pollutants.

The manufacturing process usually includes the following steps.

Strain selection. Select a microalgae strain rich in DHA, such as Schizochytrium or Ulkenia.

Culture conditions. Microalgae are cultivated in a suitable culture medium. Microalgae can be grown under controlled conditions, such as light, temperature, pH, etc., to maximize DHA production.

Culture method. Open pond culture or closed photoreactors (such as photobioreactors) can be used for cultivation. Photobioreactors can provide better culture control and higher DHA yields.

Harvesting. When the microalgae reach a certain density, they are separated from the culture medium by centrifugation, filtration, or other separation techniques.

Drying. The harvested microalgae can be dried by spray drying, freeze drying, and other methods for subsequent processing.

Oil extraction. Extract oil from dried microalgae by physical or chemical methods (such as supercritical fluid extraction and solvent extraction).

Removal of impurities. Remove impurities from oils and fats through refining processes such as degumming, deacidification, and decolorization to ensure the purity of the extract.

DHA enrichment. Further enrich DHA through fractionation, supercritical fluid extraction, or column chromatography to isolate high-concentration DHA components.

Refining. Further refining to improve the purity of DHA and remove possible oxidation products and other unwanted components.

Testing. The final DHA algae oil is tested for quality, including DHA content, oxidation value, microbial contamination, etc., to ensure safety and quality standards compliance.

Packaging. The tested DHA algae oil is packaged, usually in a light-proof and oxidation-proof manner, to maintain its stability and potency.

Through these steps, DHA Algal Oil cultivated under microalgae culture can be efficiently and safely produced and provide a sustainable and nutritious source of Omega-3 fatty acids.

Advantages Of DHA Algal Oil Produced By Microalgae

Compared with fish oil products, DHA produced by microbial fermentation has the advantages of enjoying the benefits of microbial technology, relatively less environmental damage, higher content, relatively easy purification, and the ability to produce all year round.

DHA Algal Oil VS Fish Oil: Is Algal DHA Better Than Fish Oil?

Source: Fish oil DHA resources are limited, and the output is unstable. Algal oil DHA is a sustainable resource.

Safety: Toxic marine substances are deposited in fish oil through the food chain. Algal oil DHA is more natural and reliable.

Lipids and content: The lipid composition of fish oil DHA is complex, increasing the difficulty of purification. The content of DHA is high, but the content of EPA is also high. The lipid composition of algal oil DHA is simple. Its DHA purity is high, and its EPA content is extremely low.

Properties: The DHA in fish oil DHA is active, easy to oxidize, and becomes fishy, and it is difficult to use in the food additive industry. Algal oil DHA has a super antioxidant capacity and cannot easily become fishy. It is easy to absorb and suitable for the food industry.

Purification cost: The purification process of fish oil is complex. It increases the extraction cost, and the product yield is low. The purification process of algal oil is simple, and the product yield is high.

Suitable population: Fish oil is mainly for the elderly and adults. Algal oil is particularly suitable for pregnant women and infants.

Effect: EPA contained in fish oil can reduce blood lipids and dilute blood viscosity in the elderly or adults. Algae oil contains almost no EPA. It benefits infants and young children to absorb and promote the baby’s brain and vision development.

In summary, both algae DHA and fish oil contain important omega-3 fatty acids, but they differ in several ways. Algae DHA is a plant-based product suitable for vegetarians and vegans. It is sustainably produced in a controlled environment, minimizing pollution and environmental impact. Fish oil contains both DHA and EPA, providing a wider range of omega-3. However, sustainability issues may be involved due to overfishing and potential exposure to pollutants. Perhaps algae DHA is ideal for those seeking sustainable plant-based options.

Algae Oil DHA VS Omega-3

Docosahexaenoic Acid Docosahexaenoic Acid is an important Omega-3 fatty acid and a major brain and retina structural component. It plays an important role in brain development, cognitive function, vision, and cardiovascular health. Algae oil DHA is extracted from microalgae and mainly provides DHA. It is a plant-based source of Omega-3 fatty acids, which is very suitable for vegetarians and consumers concerned about sustainability.

Omega-3 is a class of polyunsaturated fatty acids, including DHA (Docosahexaenoic Acid), EPA (Eicosapentaenoic Acid), and ALA (Alpha-Linolenic Acid). They have a variety of health benefits for the human body. Fish oil is a common source of Omega-3, usually containing DHA and EPA. DHA mainly supports brain and retinal health, while EPA is particularly important for cardiovascular health and anti-inflammatory effects.

In short, DHA algal oil is a major form of Omega-3 fatty acids, focusing on providing DHA. It makes algae oil an important source of Omega-3 for plant-based eaters and environmentalists. Compared with fish oil, algae oil provides DHA while avoiding the problem of environmental pollutants and meets the needs of sustainable development. If you need a full range of Omega-3 fatty acids, you may need a product containing EPA or choose a comprehensive source that can provide DHA and EPA.

DHA VS EPA

Docosahexaenoic acid is a long-chain unsaturated fatty acid that belongs to the Omega-3 series of polyunsaturated fatty acids. Eicosapentaenoic acid is an unsaturated fatty acid and belongs to the Omega-3 series of polyunsaturated fatty acids.

Source: DHA is mainly found in aquatic products such as deep-sea fish, shrimp, crab, shellfish, etc., and can also be synthesized by marine microalgae. EPA mainly comes from cold-water fish (such as salmon, cod, herring, etc.), marine microorganisms and phytoplankton

Molecular structure: Although both are Omega-3 series of polyunsaturated fatty acids, there are differences in their molecular structures. EPA has five unsaturated bonds, while DHA has six unsaturated bonds.

Function: DHA has unique advantages in promoting brain development, retinal cells, and optic nerve development, while EPA does not have these functions. However, much of the literature shows no significant difference between algae oil DHA and EPA in reducing triglycerides, cholesterol, and cardiovascular diseases.

Literature shows that DHA can significantly reduce dense fatty acids and platelet aggregation compared with EPA. In addition, taking algal oil DHA is more advantageous than EPA in lowering blood pressure and heart rate.

In summary, DHA and EPA are long-chain unsaturated fatty acids, but their chemical structures differ slightly. EPA is mainly found in deep-sea fish oil and lowers triglycerides, cholesterol, and blood pressure. On the other hand, DHA is mainly found in marine microalgae and breast milk and is essential for brain and visual development. There is no significant difference between EPA and DHA in their protective effects on the cardiovascular system. DHA focuses more on lowering cholesterol and preventing arteriosclerosis, while EPA focuses more on lowering triglycerides and blood pressure.
