Fish oil, cod liver oil, vitamin AD, vitamin D and vitamin D3, you are still confused? Today, we bring you a scientific article that you should read carefully. Of course, the most important thing today is to teach you how to differentiate. Fish oil vs. cod liver oil Literally understand: 1, different extraction parts, different ingredients, efficacy Fish oil: rich in DHA and EPA, can reduce blood lipids, prevention of cardiovascular disease and other effects. Cod liver oil: the main components are vitamin A and vitamin D, used for the prevention and treatment of rickets, night blindness and pediatric hand and foot convulsions. 2, suitable for different groups of people cod liver oil: children’s lack of outdoor activities, low body vitamin D stores. It is recommended that appropriate additional supplementation, the elderly non-specific type does not need to supplement. Fish oil: If breast milk or formula + complementary feeding is sufficient, infants and children do not need fish oil supplements; the elderly need appropriate supplementation. The dangers of mistaking fish oil with cod liver oil Cod liver oil and fish oil should not be confused when using cod liver oil, because the dose is small, the impact is relatively small; however, if cod liver oil is eaten as fish oil, it may lead to a large accumulation of vitamin A and vitamin D, two fat-soluble vitamins in the body, which can produce acute and chronic toxic side effects. For example, oily and itchy skin, hair loss, low gastrointestinal digestive function, etc. Cod liver oil vs. vitamin AD: Should children take cod liver oil or vitamin AD preparations when they need to supplement VA and VD? In fact, both are possible, but pay attention to the VA and VD ratios. Of course, if your baby is allergic to seafood, you should definitely buy vitamin AD preparations. Vitamin AD VS Vitamin D As we mentioned earlier, the components of vitamin AD are VA and VD, which can prevent night blindness and rickets and pediatric convulsions. Hospitals usually prescribe it after the birth of a child. But some hospitals do not prescribe vitamin AD, but vitamin D. What is this about? What is the difference between them? The ingredients and efficacy are different So, parents, although there is also vitamin D in vitamin AD, but if your child’s body is deficient in calcium and needs calcium supplementation, you must still buy vitamin D with high content and good effect so as not to waste money. The difference between vitamin D and vitamin D3 No big difference. Vitamin D3 is the highest biometabolic rate in the vitamin D family, that is, the highest utilization rate, other aspects of no major difference, basically can be regarded as the same. Finally, I would like to advise you: 1, cod liver oil is extracted from fish liver, VA:VD = 3:1 formula, more suitable for children to eat; 2, cod liver oil and vitamin AD substances are basically the same, if the child is allergic to seafood can choose vitamin AD preparations; 3, the child’s body calcium deficiency to buy vitamin D or vitamin D3; 4, vitamin D and vitamin D3, except for the metabolic rate, there is no major difference.
