Seal oil and fish oil are both health products extracted from fatty tissues of marine organisms, both of which are rich in omega-3 unsaturated fatty acids, and their functions also overlap greatly. However, there are some differences between seal oil and deep-sea fish oil, mainly in the following aspects:
1, different raw material sources
Seal oil is mainly extracted from the subcutaneous fat of seals, while deep-sea fish oil is mainly extracted from the viscera, head and bones of deep-sea fish in cold areas such as salmon and sardines.
2. Different nutrients
The molecular structure of seal oil and deep-sea fish oil is different, mainly reflected in the difference of omega-3 composition. The omega-3 unsaturated fatty acids in seal oil are mainly composed of EPA, DHA and DPA, while the omega-3 in deep-sea fish oil is only EPA and DHA. And the omega-3 content of seal oil is higher than that of fish oil, which is the highest among natural animals. Moreover, seal oil contains more squalene and vitamin E than deep-sea fish oil.
3. Other differences
Seal oil contains almost no cholesterol, while deep-sea fish oil mostly contains more cholesterol, so people with high cholesterol can eat seal oil in moderation, but it is not suitable for deep-sea fish oil.
The above is the difference between seal oil and deep-sea fish oil, so which is better?
2. Which is better, seal oil or deep-sea fish oil?
It is a question that many friends will have to choose between seal oil and deep-sea fish oil, so which of these two health products is better?
1. From the source of raw materials, deep-sea fish oil may be extracted from fish viscera, fish heads and fish bones, and the extraction process is complicated, which inevitably brings in impurities, so the purity is relatively low; Seal oil is a natural oil purified from seal oil, which is more pure and hygienic.
2. From the absorption effect, both seals and humans belong to warm-blooded mammals, and the position of ω-3 unsaturated fatty acids on triglycerides is different from that of fish. Omega-3 in mammals is in the first and third place, while fish is in the second place. In the process of human digestion, the first and third omega-3s are more likely to interact with lipase and decompose into free fat, so they can be absorbed by human body.
3. In terms of nutritional value, fish oil basically contains all the nutrients of Shanghai leopard oil, while seal oil also contains DPA, squalene, vitamin E and other nutrients on the basis of deep-sea fish oil, which has better health care effect.
To sum up, relatively speaking, seal oil is a better choice than deep sea fish oil.
