The VC content of Amway is 250mg per tablet and that of Yangshengtang is 52.8mg, so one tablet of Amway is 5 tablets of Yangshengtang. A bottle of Yangshengtang 90 yuan, Amway's seems to be 347. 1 bottle of Amway VC is equivalent to 5 bottles of Yangshengtang VC, and 90 times 5 equals 450. So in this way, Yangshengtang is more expensive than Amway's. Look at the ingredients and find that Amway VC also contains all B vitamins, so eating Amway VC or even VB is enough. It's much more cost-effective than Yangshengtang. In addition, Nutrilite now has a much better reputation than other health care products.
