How to select the best fish oil?

What is fish oil?

Fish oil is a dietary supplement that is derived from the tissues of oily fish, such as salmon, mackerel, herring, and sardines. It contains two types of omega-3 fatty acids - eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are considered essential fatty acids that the body needs for optimal health.

EPA and DHA are found primarily in fatty fish such as salmon, mackerel, and sardines, as well as in fish oil supplements. ALA is found in plant-based sources such as flaxseeds, chia seeds, and walnuts, as well as in some vegetable oils such as canola and soybean oil.

Omega-3 fatty acids are essential for optimal health and play a crucial role in several bodily functions. They are particularly important for heart health, brain function, and inflammation management. Regular consumption of omega-3 fatty acids has been associated with several potential health benefits, including reducing the risk of heart disease, improving cognitive function, and reducing inflammation in the body.

Triglyceride and ethyl ester are two forms in which omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), can be found in fish oil supplements. Here are some benefits of triglyceride fish oil over ethyl ester:

Absorption and Bioavailability: Triglyceride form of fish oil is more natural and easier for the body to absorb, metabolize and incorporate into the body's tissues than ethyl ester form, which requires extra steps to be broken down and absorbed. One study published in the Journal of the American College of Nutrition found that the bioavailability of EPA and DHA from triglyceride fish oil was 50% higher than from ethyl ester fish oil. Another study published in the Journal of Nutritional Science and Vitaminology found that the bioavailability of EPA and DHA from triglyceride fish oil was 1.7 to 1.8 times higher than from ethyl ester fish oil.

Stability: Triglyceride form of fish oil is more stable and less likely to oxidize, leading to less fishy aftertaste and odor, and better shelf life compared to ethyl ester form.

Purity: Triglyceride form of fish oil is less prone to contain impurities, such as heavy metals and environmental contaminants, because it undergoes less processing than ethyl ester form.

Clinical Studies: Clinical studies have shown that triglyceride form of fish oil is associated with better bioavailability, increased plasma levels of EPA and DHA, and improved health outcomes compared to ethyl ester form.

Naturalness: Triglyceride form of fish oil is more natural and similar to the form in which omega-3 fatty acids are found in fish, compared to ethyl ester form, which is a synthetic derivative.

What is the correct dosage of triglyceride fish oil?

The correct dosage of triglyceride fish oil supplements can vary depending on several factors, such as the individual's age, health status, and reason for taking the supplement. However, the American Heart Association recommends that individuals without documented coronary heart disease (CHD) consume a minimum of two servings of fatty fish per week, which is equivalent to about 500 milligrams (mg) per day of EPA and DHA.

For individuals with documented CHD, the American Heart Association recommends a daily intake of 1 gram (1000 mg) of EPA and DHA, preferably from fatty fish or fish oil supplements under the guidance of a healthcare professional.

It's important to note that the quality and purity of fish oil supplements can vary, and some products may contain contaminants such as heavy metals or PCBs. To ensure the safety and quality of fish oil supplements, look for products that are third-party tested and certified for purity and potency. Additionally, it's important to consult with a healthcare professional before taking fish oil supplements, particularly if you are taking any medications or have a medical condition.

Overall, triglyceride form of fish oil may be considered a better choice over ethyl ester form, as it offers better absorption, stability, purity, and naturalness.
