Thank you for posting this, the dosage amounts to a multivitamin. 120 mg of vitamin C is double the RDA, but still a small amount. And the dosage of vitamin E is also quite small (30 International Units of Vitamin E is about 20 mg alpha-tocopherol). We can argue that most in the western world would obtain these amounts from their diet. Can ew infer that a multi-vitamin, in the malnourished, can have significant health benefits? And with the prevalence of junk food in the western diet, it probably applies to a significant population in the west as well.
I also wonder what the life expectancy is of the study population. Maybe 55 is exceptionally old age in this part of China?
