Seabuckthorn, orange, lemon and kiwi fruit are all good vitamin C supplements, but I recommend seabuckthorn most, especially seabuckthorn with small fruit. The content of vitamin C is 5 times that of kiwifruit, 10 times that of orange, 80 times that of tomato and 200 times that of apple, so it is the "king of natural VC". I have been drinking seabuckthorn puree from Qinghai CommScope recently. The raw material is seabuckthorn, which has high nutritional value. It is appropriate to supplement vitamin C every day. Amway gave many friends who wanted to keep fit, and they all said yes after drinking.
