DHA (as Docosahexenoic Acid from Algae)

DHA is a structural omega-3 fatty acid with neuroprotective and nootropic effects. DHA has been shown to improve executive function, memory and learning..

Scientific Name:
Docosahexaenoic acid extracted from algae


  • DHA is the most abundant omega-3 fatty acid in the brain – main structural component of the neuronal cell membrane[1]
  • Modulates the levels of dopamine, adrenaline and noradrenaline in the brain and downregulates the HPA axis [1,2]
  • DHA modulates the transport of choline, glycine, and taurine, the function of some potassium channels, and the function of rhodopsin in synaptic vesicles[3]
  • Decreases neuronal susceptibility to oxidative stress[4]
  • Decreases the production of proinflammatory molecules and increases the levels of anti-inflammatory molecules and neuroprotectins[5]
  • Slows the rate of telomere shortening – chromosomic marker of aging[5]
  • Increased protection from neurodegeneration and decreased age-related memory loss[5]
