Ordinary ones can be bought from a cod liver oil factory in Xiamen. It seems to be Star Shark. This is an old brand, and it won't exceed 5 yuan at most. If it's better, you can buy natural vitamin E from Yangshengtang, but the price will be a little more expensive, 70-80 yuan a bottle, but the quantity is very large, as long as one tablet a day, there are One Happy and Fifty capsules/bottles.
