As you age, it becomes increasingly vital to ensure that your body is receiving all the necessary nutrients to maintain optimal health. Unfortunately, as many older adults face challenges in maintaining a varied and balanced diet, it is essential to explore alternative options to meet their nutritional needs. This article focuses on identifying the key supplements that are highly suggested for older adults with a limited diet, offering potential solutions and valuable insights to help you make informed choices for your own well-being.
Vitamin D
Importance of vitamin D for older adults
Vitamin D is an essential nutrient for older adults, as it plays a crucial role in maintaining bone health and overall wellbeing. As you age, your body’s ability to produce vitamin D naturally through sun exposure decreases, making it even more important to obtain this essential nutrient through other sources. Vitamin D aids in the absorption of calcium, which is necessary for strong and healthy bones. It also supports muscle function and helps prevent falls and fractures, which can be particularly problematic for older adults.
