Not reliable, regional differences are different, and nutritional deficiency is different (for example, there is almost no calcium deficiency in the United States, and calcium tablets sold locally contain very little calcium; However, China is generally short of calcium, and calcium tablets contain high calcium content)
Nutrition camp is different from the same type of products, which is very different!
By the way, I would like to remind you that calcium magnesium tablets (Amway China's only calcium supplement product: 228*.85*.24=46 yuan's income; 228-46= 182 yuan, excluding freight, lower than the revised price, absolutely false)
