Benefits for the cardiovascular system
Reduce blood lipids
EPA (eicosapentaenoic acid) in fish oil extract is a key component in lowering blood lipids. It inhibits the synthesis of very low-density lipoprotein (VLDL) in the liver, which primarily transports triglycerides in the blood. Therefore, reducing the synthesis of VLDL also means lowering triglyceride levels in the blood. For instance, patients with hypertriglyceridemia may experience a significant reduction in blood triglyceride levels after taking fish oil extract, thereby decreasing the risk of atherosclerosis.
Improve endothelial function of blood vessels
Endothelial cells play a crucial role in maintaining vascular health. Fish oil extract enhances the production of nitric oxide (NO) by endothelial cells in blood vessels. NO is a potent vasodilator that relaxes vascular smooth muscle, dilating blood vessels and lowering blood pressure. Additionally, NO inhibits platelet aggregation and leukocyte adhesion, reducing the risk of thrombosis. It acts like cleaning and maintaining the interior of blood vessels to ensure smoother blood flow.
Antiarrhythmic effects
The components in fish oil extract can stabilize the electrical activity of myocardial cells. Studies have found that it reduces the incidence of ventricular arrhythmias. This is because components such as DHA (docosahexaenoic acid) regulate the ion channels of myocardial cells, preventing abnormal excitation and reducing the occurrence of arrhythmias. This serves as a potential protective measure for individuals at risk of heart disease.
Benefits for the nervous system
Fetal and infant brain development
DHA is the primary structural fatty acid in the brain and retina. During pregnancy and lactation, DHA is transmitted to the fetus or infant through the placenta or breast milk after the mother consumes fish oil extract. DHA is involved in the generation, migration, and differentiation of neurons, as well as the formation of myelin sheaths during fetal brain development. Studies have shown that adequate DHA supplementation during pregnancy can enhance infants' cognitive abilities, attention, and memory. In the first few years after birth, the brain continues to develop rapidly, and appropriate supplementation with fish oil extract can further aid in brain maturation.
Improving adult cognitive function
For adults, fish oil extract can also enhance cognitive function. DHA increases the synthesis of neurotransmitters in the brain, such as dopamine and serotonin. These neurotransmitters are closely related to various cognitive functions, including learning, memory, and emotions. Long-term use of fish oil extract may improve memory, attention, and thinking abilities in adults. Studies targeting the elderly have found that supplementing with fish oil extract can help slow down cognitive decline and reduce the risk of developing dementia.
Regulate emotions and relieve stress
Fish oil extract may regulate emotions by adjusting neurotransmitter levels. Serotonin, a neurotransmitter closely associated with emotion regulation, can be influenced by fish oil extract, thereby alleviating negative emotions such as anxiety and depression. For example, in individuals under high stress, supplementing with fish oil extract can improve their emotional state and reduce their stress levels.
Benefits for eye health
Maintain normal retinal function
The photoreceptor cells in the retina are abundant in DHA. DHA maintains the structural integrity of the retina and plays a crucial role in visual signal transmission. During the light transduction process in the retina, DHA participates in the regeneration of rhodopsin, a key step in visual production. Supplementing with fish oil extract ensures sufficient DHA in the retina, maintaining normal visual function.
Preventing eye diseases
The risk of eye diseases increases with age or poor eye habits. Fish oil extract helps prevent eye diseases such as age-related macular degeneration (AMD) and retinopathy. AMD is one of the primary causes of vision loss in the elderly. DHA protects retinal cells from free radical and inflammatory damage through its antioxidant and anti-inflammatory effects, thereby reducing the risk of AMD.
