DHA: The Health Benefits of this Essential Fatty Acid

Docosahexaenoic acid, or DHA as it’s commonly known, is an essential fatty acid, or healthy fat that is necessary for healthy functioning of the human body. This omega-3 fatty acid is a primary structural component of the human brain, skin, sperm, testicles and retina. DHA, along with other essential fatty acids, are critical fats critical for both neuron structure and biochemistry.

DHA promotes the following:

  • Cardiovascular health by supporting healthy triglyceride and lipid metabolism
  • Healthy blood flow
  • Healthy platelet function
  • Vision
  • Joint health
  • Cognitive function
  • Oxygen and nutrient delivery to the brain
  • Emotional well-being
  • Positive mood

According to Naturopathic Doctor, Cathy Wong, the essential fatty acid DHA has also been described as natural remedy for a large range of health concerns, including:

  • allergies
  • asthma
  • attention deficit-hyperactivity disorder
  • dementia
  • depression
  • heart disease
  • high blood pressure
  • high cholesterol
  • psoriasis
  • Raynaud’s syndrome
  • rheumatoid arthritis
  • type 2 diabetes
  • ulcerative colitis

The human body cannot produce DHA; therefore, it is an important nutrient that must be ingested in the diet or via supplementation.
