Docosahexaenoic Acid (DHA)

Docosahexaenoic acid

DHA (Docosahexaenoic Acid) is a polyunsaturated fatty acid of the omega-3 series, essential for the human body. This fatty acid is a fundamental component of cell membranes, particularly in the brain and eyes, and plays a crucial role in the development and function of various organs. DHA is found in high concentrations in the retina and is important for the health of the central nervous system, contributing to the maintenance of neuronal plasticity, memory and cognitive function.

Production process

DHA can be produced through extraction from natural sources such as fish and microalgae. The production of DHA from algae is a sustainable process that occurs mainly through:

Fermentation: microalgae are grown in closed and sterile bioreactors to ensure a contaminant-free environment and a high-quality product.

Mechanical extraction: uses physical processes to obtain DHA oil from algae without the use of chemical solvents.
Photoautotrophic cultivation: Microalgae are cultivated using sunlight to promote the production of DHA naturally.

The oil is then extracted using innovative methods that preserve the natural characteristics of DHA, ensuring a high-quality product.

Main sources from which it derives

DHA can be obtained from a variety of sources, both plant and animal, including:

Schizochytrium sp.: one of the most common microalgae used to produce DHA. This algae is high in DHA and is a popular choice for those following a vegan or vegetarian diet;
Crypthecodinium cohnii: a microalgae used to produce DHA and EPA. This algae is particularly valued for its sustainability and is grown under controlled conditions to ensure the quality of the product;
Nannochloropsis: although it is best known for its EPA content, some varieties also contain DHA. This algae is often used to produce functional foods and supplements;
Fatty fish: DHA is also extracted from fatty fish such as salmon, mackerel and tuna, which are traditionally a primary source of omega-3s.

Food use

DHA is widely used in food supplements and nutritional products to support various aspects of health:

Cardiovascular Health: helps maintain normal triglyceride levels and blood pressure;
Brain Health: supports cognitive function, memory and proper brain development in infants;
Visual Health: is essential for the development and maintenance of visual function.
