In the era when food was not abundant, cod liver oil was an effective way to supplement vitamin AD, which could prevent dry eye syndrome, rickets, etc. During the founding of the People's Republic of China, there were cod liver oil factories, and Star Shark was one of them.
 
Founded in 1952, Star Shark is not only sold domestically, but also popular in Southeast Asia and Eastern Europe because of its low price. Although the type of Star Shark Liver Oil products is relatively old, it can still play a role in the prevention and treatment of vitamin deficiencies.
 
Star shark liver oil is made in the form of cod liver oil milk, which is a bit like a concentrated drink, and needs to be taken with warm boiled water. Compared with other imported cod liver oil, Star Shark has obtained a drug batch number, which is not a health food, and should be used under the guidance of a doctor or pharmacist. There are three types of cod liver oil milk, namely adult type, children's type, and prescription drug type, but the vitamin content is not higher than that of imported cod liver oil.
 
Star Shark Adult Cod Liver Oil Milk contains about 200mg of cod liver oil per gram, the preventive dose is 15ml per day for adults, and the therapeutic dose is 35~65ml per day for adults. It is recommended to check the blood vitamin level after 1-2 weeks of use at therapeutic doses, decide whether to continue use at therapeutic doses, and if normal levels have been reached, return to the prophylactic dose.
 
Star Shark 3D Cod Liver Oil Milk is suitable for children, made into a palatable and better sweet orange flavor, with low vitamin content, about 30IU vitamin A, 13.5IU vitamin D, and 1.54IU vitamin C per gram, which can only be used for prevention. However, Star Shark's prescription cod liver oil milk is different, the vitamin content is relatively high, containing 1500IU of vitamin A and 150IU of vitamin D per gram, which is only suitable for the treatment of vitamin deficiency, and pregnant women and children must consume the prescription cod liver oil milk (green packaging) under the guidance of a doctor.
 
Star Shark Liver Oil Milk is an early cod liver oil product, which is relatively old and does not use cod liver oil. In terms of the use effect, Star Shark can achieve the effect of supplementing vitamins A and D, but it does not have the supplemental effect of cod liver oil DHA and EPA, and it is relatively not so convenient to take. The advantage is that the price is cheaper, and a bottle of 500ml is only 16 yuan.
