Taking supplements is not always necessary for overall health, as a well-balanced diet typically provides sufficient nutrients. Research suggests that relying on whole foods rather than supplements is more beneficial, as nutrients in food are better absorbed and utilized by the body. However, certain populations such as pregnant women, elderly individuals, or those with specific medical conditions may benefit from supplements under the guidance of a healthcare professional. It's essential to prioritize dietary diversity and focus on nutrient-rich foods to maintain optimal health rather than relying solely on supplements.
