For the first time, researchers have developed a form of the omega-3 fatty acid docosahexaenoic acid (DHA) that is capable of crossing into the eye’s retina to ward off visual declines related to Alzheimer’s disease, diabetes and other disorders.
The DHA found in fish oil capsules and other supplements is typically in a form called triacylglycerol (TAG) DHA. Although TAG-DHA has benefits in other parts of the body, it does not reach the eyes because it cannot travel from the bloodstream into the retina. For the study, researchers created a new lysophospholipid form of DHA, or LPC-DHA. In studies using mice, LPC-DHA successfully increased DHA in the retina and reduced eye problems associated with Alzheimer’s-like processes.
“Dietary LPC-DHA is enormously superior to TAG-DHA in enriching retinal DHA and could be potentially beneficial for various retinopathies in patients,” said…
