DHA and EPA, what are the differences?
DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are two essential types of omega-3s that are often confused. However, their roles in the body are different and complementary.
DHA (docosahexaenoic acid)
DHA is a major structural component of brain and retinal cell membranes. It contributes to:
- Atmaintenance of normal brain function(the beneficial effect is obtained with a daily intake of 250 mg of DHA).
- Atmaintenance of normal vision(the beneficial effect is obtained with a daily intake of 250 mg of DHA).
- Atmaintaining normal blood pressure, when consumed in combination with EPA (the beneficial effect is obtained with a daily consumption of 3 g of DHA and EPA combined, without exceeding a total intake of 5 g per day).
EPA (eicosapentaenoic acid)
The EPA is primarily recognized for its role in:
- THEmaintenance of normal heart function, in association with DHA (the beneficial effect is obtained with a daily intake of 250 mg of EPA and DHA).
Although the body can convert some EPA to DHA, this conversion is limited and insufficient to meet optimal DHA needs, particularly for the brain and eyes.
DHA is therefore considered to beessential, especially for pregnant and breastfeeding women, where it supports the development of the fetus's brain and vision.
Traditionally, fish oils provide these omega-3s, but they can be sourced from intensive fishing and may contain contaminants.
Algal oils, such as DHA from Schizochytrium Sp., offer a pure, sustainable and environmentally friendly alternative with no impact on marine life.
