Nutritional supplements can effectively complement a well-balanced diet by providing essential nutrients that may be lacking due to dietary restrictions or increased physical demands. Vitamins, minerals, and protein powders can aid in recovery, support immune function, and enhance energy levels. However, supplements should not replace nutrient-dense foods but rather serve as an addition to address specific needs. Consulting with a healthcare professional is vital to ensure proper supplementation that aligns with individual health goals and dietary habits.
