Vitamins are essential nutrients that the body needs to grow, function properly, and stay healthy. They participate in a wide range of processes, such as supporting immune function, strengthening bones, enabling cellular repair, and assisting with energy release from food. Vitamins help protect against a variety of health problems, including certain deficiencies, weakened immunity, and impaired vision, by ensuring that all the body’s systems operate smoothly. In situations where dietary intake is limited due to age, illness, or changing appetite, supplementing with the right balance of vitamins can make a meaningful difference in wellbeing and recovery.
