Health care for the elderly mainly focuses on cardiovascular and cerebrovascular diseases and calcium supplementation. There are fish oil, lecithin, propolis, calcium and so on. In the market, people who know the elderly are fine. People who don't know will almost certainly choose low prices instead of high content and good ingredients ~
I feel that if you really want to do it, first of all, your product should have certain advantages. For example, is calcium easily absorbed by the human body? Is it what the human body needs every day?
Whether you like dealing with the elderly or not, because as you said, you mainly deal with elderly customers. If you don't like it, exercise slowly and communicate with the elderly bravely, so that you can sell yourself @!
I believe that as long as you have patience and hard work, you will do it well.
