Generally speaking, it is ineffective for the elderly to take supplements, because supplements are invincible in advertising, but they are actually vitamins and trace elements, and there are some nutrients, but the human body can only absorb some nutrients, and more will be excluded. As long as you usually eat well-off aquatic products (three dishes and one soup), nutrition is enough. The key is scientific collocation and eating more vegetables. It is not easy for the elderly not to eat meat and eggs, otherwise they will get high blood pressure, cerebral thrombosis and diabetes. If you always shout pain, it may be that you are ill. You should go to a regular hospital for examination and let the doctor handle it. It may also be a neurological or psychological problem. It is common sense that "it is not enough to make up for it". If you use supplements indiscriminately and waste money, it may be counterproductive. You should believe in science, not advertising. There is also to let your grandmother exercise more, with less intensity, and learn more health-keeping methods according to her feelings. I wish your grandmother a long life. I love her very much.
