The industry of health care products can be said to be very violent, and many health care product promoters mainly sell to the elderly. Faced with each other's hype, many elderly people can't resist the temptation and will spend huge sums of money to buy it.

In modern society, people pay more and more attention to health care. It is ok to eat some health care products properly, but don't be too obsessed with health care products, because no matter what kind of health care products, they can only enhance your physique in some ways. I think if your father is crazy about health care products, you can show your father some videos that expose health care products scams online and explain them to your father with real examples. If it really doesn't work, you can go to the hospital to find a doctor and ask professionals to explain the function and usage of health care products to your father, so I believe your father will understand and be considerate.
