Understanding Docosahexaenoic Acid (DHA): A Nutrient for Human Health

Docosahexaenoic Acid (DHA) is an omega-3 fatty acid that is a structural component of the brain and retina. DHA is an essential fatty acid that cannot be produced efficiently by the human body and must be obtained through diet or supplementation.

Role in the Body

DHA is a component of cell membranes, particularly in the brain, retina, and nervous system.

Specific Functions

• Contributes to brain structure

• Maintains cellular membrane structure

• Supports cellular communication

• Contributes to vision

Effects of Low Intake

Low DHA intake may be associated with:

• Potential changes in cognitive function

• Potential impacts on brain development

Dietary Sources

Best Food Sources

DHA is found in:

• Fatty fish (salmon, mackerel, herring, sardines)

• Fish oil

• Algae and seaweed

• Fish roe

• Some shellfish

Supplementation

Supplementation may be considered for individuals who:

• Follow a vegetarian or vegan diet

• Have limited access to fatty fish

• Are pregnant or breastfeeding

Health Considerations

Brain Health

Some studies suggest DHA may play a role in supporting brain function.

Pregnancy and Development

DHA is important for fetal development and is a component of brain and eye tissues.

Cardiovascular Health

Some research indicates potential cardiovascular benefits of omega-3 fatty acids.

Daily Intake Guidelines

Recommended daily intake varies:

• Adults: 250-500mg combined EPA and DHA per day

• Pregnant women: Consult healthcare provider
