Most people do not get enough vitamins and minerals in their daily diet. In these cases, a dietary supplement can be very helpful in replacing the vitamins and minerals that are lost through the course of the day. Those most likely
to need a supplement to fill the gaps in their diet are those on a low-calorie diet, those who have been sick, and those who do not have a varied enough diet (such as vegetarians or those with food allergies). As science and technology advances, a difference in the daily needs of men and women have been found, and a men’s vitamin supplement supplies the vitamins and minerals most commonly needed by men, and thus are more effective for men.
