It seems that Omega-3 is from Jongkundang Health.

When checking the omega ingredients, it is important to carefully verify whether it is RTG, plant-based ingredients, or if a low-temperature extraction method was used. In particular, products with an excessively fishy smell may cause reluctance to take them regardless of their effectiveness, so careful selection is necessary. Additionally, due to severe ocean pollution these days, if the raw materials come from large fish species, there is a risk of ingesting mercury, lead, and other toxins, so using small fish species as raw materials is also important.

Jongkundang Health's Omega-3 and Ginkgo are in RTG form, contain fewer impurities, and are said to have excellent absorption in the body.

The pill is a bit large, so it might be a bit burdensome, but it hardly has any fishy smell, so you can swallow it like taking vitamins. I recommend Omega-3 made by Jongkundang, a leading pharmaceutical company in Korea, because you can trust the quality of the raw materials.
