Which is better, DHA or EPA

DHA and EPA each have their own advantages, with DHA being more suitable for brain development in infants and young children and cognitive function maintenance in middle-aged and elderly people, while EPA has more significant effects on cardiovascular health and anti-inflammatory effects. When choosing, individual needs should be taken into account, mainly including growth and development needs, cardiovascular protection needs, anti-inflammatory regulation needs, nervous system maintenance needs, and supplementary needs for special populations.

1. Growth and Development Requirements

DHA is the main structural component of the cerebral cortex and retina, and plays a crucial role in the neural development of fetuses and infants. Adequate daily intake of DHA by pregnant women can promote fetal brain cell proliferation, and supplementing DHA in premature infants can improve visual acuity. Continuous supplementation of DHA in children is associated with improved language expression ability, and it is recommended to obtain it through breast milk, formula milk, or deep-sea fish.

II. Cardiovascular protection requirements

EPA can significantly reduce the level of triglycerides in the blood, inhibit the excessive aggregation of platelets, and reduce the formation of atherosclerotic plaque. Long term intake of EPA can improve endothelial function and has a protective effect on patients with hypertension and hyperlipidemia. Clinical trials have shown that EPA can reduce the probability of cardiovascular events and is suitable for individuals with a family history of coronary heart disease.

III. Anti inflammatory regulatory requirements

EPA is converted into anti-inflammatory mediators in the body, which can alleviate joint swelling in patients with rheumatoid arthritis. EPA can regulate pro-inflammatory cytokine levels in chronic inflammatory diseases such as psoriasis and irritable bowel syndrome. When patients with autoimmune diseases use EPA and DHA in combination, EPA plays a dominant anti-inflammatory role.

4. Neurological maintenance requirements

DHA accounts for 40% of the fatty acids in the adult brain, and supplementing DHA can slow down the rate of cognitive decline. The DHA content in the brain of Alzheimer's disease patients is generally low, and moderate supplementation can help maintain neuronal membrane stability. When patients with depression supplement EPA and DHA together, EPA has a more significant effect on mood improvement.

V. Supplemental Needs of Special Groups

Vegetarians are advised to choose algal oil DHA to avoid EPA deficiency, and athletes can increase EPA intake to reduce post exercise inflammatory reactions. Pregnant women should ensure a daily intake of DHA, and those at high cardiovascular risk should focus on EPA supplementation. Individuals with abnormal liver and kidney function should adjust the ratio of the two under the guidance of a doctor.

Deep sea fish, such as sardine and salmon, contain both DHA and EPA in daily diet. It is recommended to take them two to three times a week. When choosing supplements, attention should be paid to product purity and proportion. Cardiovascular disease patients can choose formulas with a high proportion of EPA, and pregnant women should choose supplements mainly composed of DHA. People who are allergic to fish can obtain alpha linolenic acid from plant sources such as flaxseed oil, which is partially converted into DHA and EPA in the body. Long term use of anticoagulant drugs requires monitoring of their intake to avoid affecting coagulation function. During storage, it is necessary to avoid light and moisture to maintain the stability of the active ingredients.
