The research conclusion of Harvard University in 25 years shows that there is no obvious difference in 5 years. 10 years can reduce the prevalence rate by 25%; 15 years, the prevalence rate decreased by 75%. I'm not sure if this is true or not.

Harvard University also reported an experiment. They don't know what health products to give the experimenters. Health care products are just a category, and there are too many things in them.

It is certain that taking health care products correctly is beneficial to human body, but the reported timeliness of taking them does not represent the whole story. Personally, I don't need to take health care products for so long to achieve the above effects. But health care products need to be taken for a long time, which is for sure.
