How DHA Can Protect Your Eyes, Making Them Immune To Injury

How DHA Can Protect Your Eyes, Making Them Immune To Injury |

If you want to protect your vision, taking Omega-3 fatty acid DHA (Docosahexaenoic acid) can pre-condition your vision cells to survive injury. That’s according to research into the effects of DHA as a form of vaccine or immunity.

The study was written about in the Cellular and Molecular Neurobiology journal and explains why Omega-3 and its components can protect cells, making it essential for protecting and maintaining good vision.

Researchers found that DHA and docosanoids are responsible for “activating the sustained cellular mechanisms that elicit long-term preconditioning protection,” according to Professor Nicolas Bazan, MD, PhD, Director of LSU Health New Orleans Neuroscience Center of Excellence.

It is this pre-conditioning (PC) stimulus that can activate a protective response to a future lethal stimulus. This often occurs when blood supply to the organ is interrupted for a short time and then re-established.

A protective response often occurs from the first injury and then this is carried over to a subsequent blood supply shortage. This is just like the immunity that a vaccine provides against future exposure to disease. This happens within the heart, brain and the retina, along with other organs. Researchers say it is important to identify what the molecules are that are directly involved in this process.

DHA Could Be The Essential Key To Good Eye Health

Polyunsaturated fatty acids (PUFAs) are found in two kinds within fish oil. These often have very different actions and include Omega-3s (Docosahexaenoic acid – DHA) and Omega-6s such as Arachidonic Acid (AA).

DHA and its docosanoids (DHA’s metabolic derivatives), have been shown to contain the most powerful anti-inflammatory properties. Omega-6 fatty acids and their components have been suggested to be widely pro-inflammatory however.

Bazan’s team found that while they are often released one after the other, DHA can affect the actions of AA. When DHA was supplemented prior to oxidative stress, the synthesis of protective DHA derivatives increased while the AA synthesis was found to have decreased over time.

The Lead Researcher commented that the findings demonstrate how DHA and docosanoid synthesis is necessary for preconditioning protection, and the daily survival of photoreceptor and RPE cells.

Omega-3 impairments are usually associated with neuro-inflammation and this contributes to both photoreceptor cell dysfunction and death. Enhancing the synthesis of docosanoids can provide an opportunity for stopping or making better debilitating regenerative diseases, including the dry form of age-related macular degeneration.

All of the above evidence highlights the importance of how essential Omega 3 fatty acids are for good health. These fatty acids are often found in fish oils. One of the best ways to ensure you get a sufficient amount of DHA and EPA into your body is to add a good Omega 3, 6 and 9 supplement such as Krill Oil into your daily routine.

    This sounds great but at if you can’t eat any fish a allergic aretheee by non fish alternatives?

      Hello Claire, DHA supplements derived from fish oil are an excellent source of the valuable omega-3 fatty acid. But vegans and vegetarians, until recently, had no practical and acceptable source for DHA. A new process now enables DHA to be extracted from algae, by means of completely vegan-friendly techniques. You can search for these on the market.
      While EPA & DHA are mainly found in oily fish, the body can convert ALA to EPA and DHA. Hemp Oil is a a good source of ALA and again makes a good option for those unable to tolerate fish or want vegan alternatives.

        You are right about EPA & DHA because it nourishes deep tissue in the reproductive organs especially plant-based
