Fish seed oil, fish oil and cod liver oil are all extracted from fish, but the extracted parts are different. Fish seed oil is extracted from the eggs of Arctic herring, fish oil is extracted from the fat layer of deep-sea fish, and cod liver oil is extracted from fish liver.
The function is also different: fish oil is a supplement to human unsaturated fatty acids, containing EPA and DHA. EPA can reduce cholesterol and triglycerides in human blood, while DHA plays an important role in brain and retina, and fish oil contains phospholipid DHA, which is more absorbed and utilized than fish oil. Cod liver oil mainly supplements vitamins A and D. Vitamin A helps to maintain vision and promote growth and development. Vitamin D promotes the absorption of calcium and is beneficial to bone growth.
DHA in seaweed oil and fish seed oil will be different in raw materials and absorption and utilization rate. Fish seed oil DHA is made of high-end food raw materials such as wild herring seeds in the Arctic, which naturally contains phospholipid DHA, and its absorption and utilization rate is 3-5 times that of ordinary DHA in the market.
Moreover, bile salts do not need to be emulsified during digestion, which is easier to digest and can reduce the burden on the liver. But seaweed oil and fish oil need bile salts secreted by the liver and gallbladder to help digestion.
In addition, fish seed oil naturally contains choline, which plays an important role in promoting brain development and improving memory, which seaweed oil and fish oil do not have.
