Is it better to have EPA in DHA or not

DHA supplements with or without EPA have their own applicable scenarios, and the choice should be based on specific needs. DHA containing EPA is suitable for people who need to regulate blood lipids and have anti-inflammatory effects; DHA without EPA is more suitable for special populations such as infants and pregnant women who need to avoid excessive intake of EPA. DHA supplements containing EPA are usually extracted from deep-sea fish oil. The synergistic effect of EPA and DHA can reduce triglycerides, improve blood circulation, and be beneficial for cardiovascular health. This type of product is suitable for middle-aged and elderly people or those at risk of hyperlipidemia and arteriosclerosis. But EPA may affect the growth and development of infants and young children, and excessive intake may interfere with arachidonic acid metabolism. DHA without EPA is mostly extracted from algal oil, with higher purity and better safety. Algae oil DHA avoids EPA interference and is more suitable for fetal neurodevelopmental needs. Pregnant women, lactating women, and infants should prioritize this type of supplement. Some individuals who are sensitive to fishy odors or herbivores can also choose algal oil DHA, but it should be noted that algal oil may lack the anti-inflammatory synergistic effect of EPA. When choosing DHA supplements, one should consider their own health condition and needs. The recommended daily intake of DHA for adults should not exceed 1000 milligrams, and infants and young children should adjust their dosage according to their weight. It is recommended to consult a nutritionist or avoid taking anticoagulant drugs together before long-term use. Omega-3 fatty acids can be supplemented daily by eating deep-sea fish such as salmon and sardine or plant foods such as flaxseed and walnut.
