Regarding the consumption of fish oil?
I previously saw a doctor's response, but I still have some questions regarding fish oil consumption.
Could you please advise me, doctor? What is the optimal daily intake of EPA and DHA combined for an individual? What are the potential effects if the intake is insufficient? Additionally, if it is necessary to take calcium supplements alongside fish oil, how should they be taken to avoid saponification? Lastly, is it advisable to avoid daily consumption of fish oil? Thank you for your assistance with these questions.

Hello: 1.
Fish oil EPA belongs to omega-3 fatty acids, while DHA is a polyunsaturated fatty acid.
Most fish oils contain 18% EPA and 12% DHA.
2.
Fish oil is more suitable for the elderly and patients with cardiovascular diseases.
According to the FDA (Food and Drug Administration) dosage guidelines, it is recommended not to exceed 2.5 g of fish oil capsules per day.
Due to the high content of polyunsaturated fatty acids (EPA and DHA) in fish oil, it is prone to oxidation, leading to the production of free radicals.
Excessive free radicals can cause abnormalities in lipid metabolism, disrupt the immune system, contribute to atherosclerosis, and even trigger cancer; therefore, caution is advised when consuming fish oil capsules.
3.
Taking fish oil and calcium supplements together may lead to saponification, resulting in diarrhea.
If it is necessary to take both, it is advisable to space them apart by more than two hours.
4.
If you wish to purchase fish oil, the Food and Drug Administration has approved fish oil health products, which can be checked at http://food.doh.gov.tw/foodnew/info/InfoHealthFoodList.aspx.
5.
Dietary supplements are not as beneficial as food supplements; obtaining nutrients from natural food sources is more reliable.
What natural foods can replace fish oil? Sardines, mackerel, tuna, and salmon are all excellent choices.
For vegetarians who cannot consume fish and do not wish to take fish oil, "perilla" can be used as a substitute.
6.
Precautions for consumption: 1.
Young people: It is recommended to obtain EPA and DHA from natural seafood rather than encouraging young individuals to take health supplements.
2.
Individuals allergic to seafood: They may not be aware of which part of the fish they are allergic to, and since fish oil can be extracted from various parts, it is not advisable for those with allergies to consume it.
3.
Individuals taking other medications: Those on aspirin, lipid-lowering medications, or with coagulation disorders (such as hemophilia) should also avoid fish oil, as both aspirin and fish oil can enhance blood circulation, potentially leading to adverse effects.
Wishing you health and safety.

More Info
When it comes to the optimal daily intake of EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) from fish oil, the general recommendation varies based on individual health needs, age, and dietary habits. For most adults, a combined daily intake of 250-500 mg of EPA and DHA is often suggested for general health benefits, particularly for cardiovascular health. However, specific populations, such as those with heart disease or high triglyceride levels, may benefit from higher doses, sometimes up to 2-4 grams per day, under medical supervision.
If the intake of EPA and DHA is insufficient, individuals may experience a range of health issues. Omega-3 fatty acids are crucial for various bodily functions, including reducing inflammation, supporting heart health, and promoting brain function. A deficiency in these fatty acids can lead to increased inflammation, higher risk of cardiovascular diseases, cognitive decline, and mood disorders. Therefore, ensuring adequate intake is essential for maintaining overall health.
Regarding the concurrent use of fish oil and calcium supplements, it is important to note that taking them together can lead to a phenomenon known as saponification, where the fatty acids in fish oil may bind with calcium, potentially leading to gastrointestinal issues such as diarrhea. To avoid this, it is advisable to space the intake of fish oil and calcium supplements by at least two hours. This allows for better absorption of both supplements without the risk of interaction.
As for the frequency of fish oil consumption, it is generally safe for most people to take fish oil daily, provided that they adhere to the recommended dosages. However, some individuals may choose to cycle their intake, taking fish oil for a period and then pausing, especially if they are consuming a diet rich in omega-3 fatty acids from natural sources like fatty fish (e.g., salmon, mackerel, sardines). The key is to balance supplementation with dietary sources to achieve optimal health benefits.
It is also worth noting that while fish oil supplements can be beneficial, they should not replace a balanced diet. Whole foods provide not only omega-3 fatty acids but also other essential nutrients that contribute to overall health. For those who do not consume fish, plant-based sources of omega-3s, such as flaxseeds, chia seeds, and walnuts, can be good alternatives.
In summary, the optimal daily intake of EPA and DHA from fish oil typically ranges from 250-500 mg for general health, with higher doses for specific health conditions. It is crucial to avoid taking fish oil and calcium supplements simultaneously to prevent gastrointestinal issues. Daily consumption of fish oil is generally safe, but it is essential to consider dietary sources and individual health needs. Always consult with a healthcare provider before starting any new supplement regimen, especially if you have underlying health conditions or are taking other medications.
