Cod liver oil slows coronary disease
Inhibition of atherosclerosis by cod-liver oil in a hyperlipidemic swine model.
High relevance to heart disease
We investigated how cod liver oil affects coronary artery disease in pigs on a high-fat diet over eight months. By comparing 7 pigs that received cod liver oil to 11 control pigs, we observed significantly less disease in the oil-fed group. Notably, lesion size and arterial narrowing were reduced, suggesting that cod liver oil may influence heart health. Both groups had high lipid levels, but the differences in atherosclerosis weren't linked to these levels. This study hints at the oil's potential to slow coronary disease progression via changes in metabolism.

Cod liver oil aids heart health
Cod liver oil supplementation improves cardiovascular and metabolic abnormalities in streptozotocin diabetic rats.
Directly addresses heart disease
We delved into how cod liver oil (CLO) influences heart health, especially in the context of diabetes. Using a study with streptozotocin (STZ)-induced diabetic rats, we treated them with CLO and monitored various cardiovascular metrics over 12 weeks. What we found was quite telling: untreated diabetic rats faced significant increases in blood sugar and harmful lipid levels, while those receiving CLO showed improved weight gain and complete prevention of lipid problems.

Moreover, the study revealed that CLO-treated rats exhibited healthier blood vessel responses and heart function. For instance, we observed that CLO effectively corrected some vasoconstriction issues and improved heart rhythm responses that were otherwise diminished in diabetic rats. The treatment also helped preserve the structural integrity of heart tissue, which often suffers in diabetes.

Overall, this research strongly suggests that cod liver oil can be a valuable supplement for mitigating heart disease risks associated with diabetes. With its rich omega-3 fatty acids and antioxidants, CLO appears to play a protective role in maintaining cardiovascular health in diabetic settings.

Cod liver oil may stabilize heart
[Correction of disorders of cardiac electric stability in post-infarction cardiosclerosis using a diet enriched with polyunsaturated fatty acids].
Moderate relevance to heart disease.
We examined the effects of cod liver oil, enriched with essential fatty acids, on heart stability after inducing myocardial infarction in rats. Over 30 days, we found that the oil significantly raised the heart's fibrillation threshold by 50% and halved the occurrence of spontaneous extrasystoles. While there were improvements in the heart's functionality during rest, overall heart pressures and contraction speeds showed no significant changes. This suggests that cod liver oil may contribute positively to heart stability, but it doesn't dramatically alter all heart functions.

Supports immunity
Cod liver oil significantly benefits skin health and delays ageing. It supports heart health, memory, and reduces diabetes risk. Additionally, it boosts immunity against infections and aids in lowering triglycerides and cholesterol. It’s derived from cod liver, providing higher vitamins A and D than regular fish oils.

Combats inflammation
The quality is excellent with clear ingredients, making it one of the best supplements for ageing. I noticed benefits quickly, especially in combating inflammation. The taste is almost non-existent and it supports heart health. The packaging is substantial and it is great for hair health as well.

Cod liver oil aids heart recovery
Docosahexaenoic Acid-Enhanced Autophagic Flux Improves Cardiac Dysfunction after Myocardial Infarction by Targeting the AMPK/mTOR Signaling Pathway.
High relevance for cardiovascular research
We explored the effects of docosahexaenoic acid (DHA), found in cod liver oil, on heart health after a heart attack. Using lab tests on heart cells and mouse models, we found that DHA helped protect heart cells from damage due to low oxygen levels.

Remarkably, DHA not only reduced heart damage but also improved heart function overall. It seemed to support a process called autophagy, which helps clear out damaged cells, thereby benefiting heart health after injury.

However, it's important to note that while DHA shows promising results, more research is needed to fully understand its role.

Cod liver oil's potential heart benefits
Effects of n-3 polyunsaturated fatty acids on coronary heart disease.
Study highlights fatty acid balance
We explored the relationship between n-3 polyunsaturated fatty acids, particularly from cod liver oil, and coronary heart disease (CHD). The research found that cod liver oil significantly reduced harmful arachidonic acid levels in heart cells, promoting a healthier balance with beneficial docosahexaenoic acid. This balance may lower risks of heart issues, including sudden cardiac death. However, while diets rich in fish oil show promise, the study does not claim that cod liver oil is a guaranteed solution to heart disease.
