Many of today’s older Americans are malnourished, and the reasons are rather obvious upon closer inspection. The same medications that so many elderly people take to live healthy lives have a detrimental side effect: they limit appetite. That means that the older generation is trying to function without all of the vitamins and minerals recommended by doctors and nutritionists.

We also need vitamins to boost immune system function. In order to create effective antibodies that fight off germs and disease, we need a full complement of Vitamin D and calcium. These vitamins work in tandem to strengthen the immune system. Vitamin D is especially important for those senior citizens with mobility issues who might not get all of the sunlight they need.
