Supplements can play a significant role in supporting a healthy diet by filling nutrient gaps that might exist due to dietary restrictions or inconsistent eating habits. They provide concentrated doses of essential vitamins, minerals, and other bioactive compounds that support overall well-being. For instance, individuals may use multivitamins to ensure they meet daily requirements, while athletes might opt for protein powders to assist with recovery and muscle growth. However, it is important to remember that supplements should complement, rather than replace, whole foods in a balanced diet, ensuring that diverse nutrients are consumed naturally for optimal health.
