A nurse is developing an education program about dietary supplements. Which of the following clients would benefit from a dietary supplement?

A. Having a family history of heart disease does not automatically indicate a need for dietary supplements. Heart disease risk is influenced by lifestyle factors such as diet, exercise, smoking, and cholesterol levels. Preventive strategies like a heart-healthy diet and regular physical activity are preferred over routine supplementation unless specific deficiencies are identified. B. Clients at risk for osteoporosis can benefit from dietary supplements such as calcium and vitamin D. These nutrients are essential for maintaining bone density and preventing fractures, especially in populations at higher risk, such as older adults or postmenopausal women. Supplementation helps address deficiencies that cannot be met through diet alone. C. While some vitamins and minerals, like vitamin C or zinc, may support immune function, they do not treat or cure an acute upper respiratory infection. Supplementation in this context is not considered a primary intervention and is unlikely to significantly impact recovery.
