We investigated the impact of diabetes on the levels of docosahexaenoic acid (DHA), an essential omega 3 fatty acid, in the retina of humans and mice. Our findings revealed that diabetic individuals had significantly lower DHA levels—40% less in peripheral regions and 25% less in the macula—compared to those without diabetes.
Additionally, we observed a reduction of retinal thickness and function in diabetic mice. Although there’s potential for dietary DHA to help with diabetic retinopathy, the current study suggests that diabetes is linked to reduced DHA and related retinal defects.

Frequently Asked Questions
Diabetes is a chronic medical condition that occurs when the body either does not produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone made by the pancreas that helps glucose from food enter the cells, providing them with energy. When diabetes is present, it leads to elevated levels of glucose in the blood, which can cause serious health complications if left unmanaged. There are primarily two types: Type 1 diabetes, which is an autoimmune condition where the body attacks insulin-producing cells, and Type 2 diabetes, which is often associated with lifestyle factors such as obesity and lack of physical activity, leading to insulin resistance.
Managing diabetes typically involves a combination of lifestyle changes, such as a balanced diet and regular exercise, along with monitoring blood sugar levels and, in many cases, medication or insulin therapy. Education is crucial for those with diabetes to understand how their condition works and how to manage it effectively. The goal of diabetes management is to keep blood sugar levels within a target range, helping to prevent complications such as heart disease, nerve damage, and kidney failure. Regular check-ups and consultations with healthcare professionals are essential to ensure optimal care.
Omega-3 fish oil is a nutritional supplement derived from the fatty tissues of fish, particularly fatty fish like salmon, mackerel, and sardines. It is rich in omega-3 fatty acids, which are essential fats that the body cannot produce on its own. The most significant types of omega-3s found in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are known for their numerous health benefits. These include reducing inflammation, supporting heart health, and promoting brain function.
Incorporating omega-3 fish oil into your diet can be beneficial if you don’t consume enough fish regularly. Many health experts recommend oily fish as a part of a balanced diet due to their high omega-3 content. For those who find it difficult to include fish in their meals, fish oil supplements can offer a convenient alternative, providing the same essential fatty acids in concentrated form. However, it’s essential to choose high-quality supplements that are third-party tested for purity and potency to avoid contaminants such as heavy metals or other toxins that can impact health.
Recent studies suggest that Omega-3 fish oil might play a role in managing diabetes, but the findings are not entirely conclusive. Omega-3 fatty acids, primarily found in fish oil, are known for their anti-inflammatory properties and potential to improve cardiovascular health. Some research indicates that they may help in reducing insulin resistance, which is a critical factor in type 2 diabetes management. However, while fish oil supplements may offer some benefits, they should not be relied upon as the sole treatment for diabetes.
It's important to note that more research is needed to establish a clear connection between Omega-3 fish oil and diabetes management. For those considering adding Omega-3 supplements to their diet, it’s advisable to consult with a healthcare professional. They can provide tailored advice based on individual health needs and conditions. Additionally, incorporating a balanced diet rich in omega-3 sources like fatty fish, walnuts, and flaxseeds, along with regular physical activity and proper blood sugar monitoring, remains the cornerstone of diabetes management.
When taking Omega-3 fish oil for diabetes, the timeline for seeing results can vary significantly based on individual health factors, dosage, and overall adherence to a prescribed health regimen. Generally, users may start to notice changes in their blood sugar levels or associated markers such as triglycerides within a few weeks to a few months. Some studies suggest that regular intake can lead to meaningful changes in insulin sensitivity and lipid profiles within about 8 to 12 weeks.
It's important to note that Omega-3 fish oil is often used as a complement to a well-rounded diet and lifestyle modifications rather than a standalone treatment. Therefore, while some individuals report feeling benefits in energy levels and mood relatively quickly, it’s essential to manage expectations and continue working closely with healthcare providers for comprehensive diabetes management. If you're considering the integration of Omega-3 fish oil into your routine, tracking progress over a few months can provide clearer insights into its effects on your blood sugar control.
